DNS Server Not Responding on Windows? 7 Ways to Get Back Online

Getting “DNS server not responding” on Windows? Fix it fast with 7 proven methods — flush your DNS cache, switch to Google’s 8.8.8.8 DNS, and reset TCP/IP. Back online in minutes.

You open your browser, type in a website, and get hit with a frustrating message: “DNS server not responding.” Your Wi-Fi shows connected, everything looks fine — but nothing loads. This error means your computer can’t translate website names (like google.com) into the numeric IP addresses it needs to reach them, a process handled by DNS (Domain Name System), which works like the internet’s phone book.

The good news: this is one of the most fixable Windows errors out there. It’s almost always caused by a stale DNS cache, a momentary router glitch, or a misconfigured DNS setting — none of which require technical skills to fix.

This guide walks you through 7 proven fixes for the “DNS server not responding” error on Windows, starting with the fastest and easiest.

Quick Answer

To fix “DNS server not responding” on Windows, restart your router and flush your DNS cache by running ipconfig /flushdns in Command Prompt (as administrator). If the error persists, switch your DNS server to Google’s (8.8.8.8 / 8.8.4.4) or Cloudflare’s (1.1.1.1 / 1.0.0.1) in your network adapter settings. Most cases are resolved by these three steps alone.

What Causes “DNS Server Not Responding”?

When you type a website address, Windows contacts a DNS server to look up that site’s IP address. If that lookup fails for any reason, you see this error. The most common causes are:

  • Router crash or overload — your router needs a simple restart to clear its memory.
  • Corrupted DNS cache — old or incorrect address records saved on your PC cause the lookup to fail.
  • ISP’s DNS server is down — your provider’s servers are slow, overloaded, or temporarily unavailable.
  • Outdated network adapter driver — the software controlling your Wi-Fi or Ethernet card has a bug.
  • Antivirus or firewall blocking DNS — security software is intercepting and blocking DNS requests as a side effect.
  • Corrupted TCP/IP stack — Windows’ core networking settings have become misconfigured.

7 Fixes for “DNS Server Not Responding” on Windows

Work through these fixes in order. Most people are back online after Fix 1, 2, or 3.

Fix 1: Restart Your Router and Modem

A router restart is the single most effective first step. It clears the router’s memory, drops stale connections, and picks up a fresh DNS assignment from your ISP. If every device in your home is affected — phones, tablets, laptops — this is almost certainly the fix.

  1. Unplug your router (and modem, if it’s a separate box) from the power outlet.
  2. Wait 30 seconds.
  3. Plug the modem back in first. Wait until its indicator lights stabilize — about 60 seconds.
  4. Plug the router back in. Wait another 60 seconds.
  5. Try loading a website on the affected device.

Pro tip: Always unplug the power cable rather than pressing the router’s physical Reset button. The Reset button restores factory settings and wipes your custom Wi-Fi password — unplugging the power does not.

Fix 2: Flush Your DNS Cache

Windows saves DNS lookups in a local cache to speed up browsing, but that cache can become stale or corrupted over time. Flushing it forces Windows to fetch fresh records for every site you visit.

  1. Press Windows key + R, type cmd, then press Ctrl + Shift + Enter to open Command Prompt as administrator.
  2. Type the following command and press Enter:
    ipconfig /flushdns
  3. You should see the message: “Successfully flushed the DNS Resolver Cache.”
  4. Restart your browser and test a website.

Troubleshooting tip: If you see “Access is denied,” you didn’t open Command Prompt as administrator. Close the window, search for Command Prompt in the Start menu, right-click it, and choose Run as administrator.

Fix 3: Switch to Google’s or Cloudflare’s DNS Server

Your ISP’s DNS server may be down or simply too slow. Switching to a fast, reliable public DNS server — like Google’s or Cloudflare’s — is one of the most effective fixes, and it often speeds up your browsing as a bonus.

  1. Press Windows key + R, type ncpa.cpl, and press Enter to open Network Connections.
  2. Right-click your active connection (Wi-Fi or Ethernet) and select Properties.
  3. Click Internet Protocol Version 4 (TCP/IPv4), then click Properties.
  4. Select Use the following DNS server addresses and enter:
    Preferred DNS server: 8.8.8.8
    Alternate DNS server: 8.8.4.4
  5. Click OK, then Close. Open a browser and test.

Not sure which public DNS to use? Here are the three most popular free resolvers and their server addresses:

Provider Primary DNS Secondary DNS
Google Public DNS 8.8.8.8 8.8.4.4
Cloudflare 1.1.1.1 1.0.0.1
OpenDNS 208.67.222.222 208.67.220.220

Pro tip: Cloudflare’s DNS (1.1.1.1 / 1.0.0.1) is a strong alternative — it’s consistently one of the fastest DNS resolvers worldwide and has a privacy-first approach that doesn’t log your browsing activity.

Fix 4: Restart the DNS Client Service

Windows runs a background process called the DNS Client service that handles all DNS lookups. If it has frozen or crashed, restarting it can clear the error without any other changes needed.

  1. Press Windows key + R, type services.msc, and press Enter.
  2. Scroll down the list to DNS Client.
  3. Right-click it and select Restart.
  4. If Restart is greyed out, the service is managed automatically by Windows — move on to Fix 5.

Fix 5: Reset Your TCP/IP Stack and Winsock

The TCP/IP stack and Winsock catalog are the core components Windows uses to communicate on any network. Corruption in either can cause persistent DNS errors. Resetting them is completely safe and takes about two minutes.

  1. Open Command Prompt as administrator (see Fix 2, step 1).
  2. Run each command below, pressing Enter after each one:
    netsh winsock reset
    netsh int ip reset
    ipconfig /release
    ipconfig /flushdns
    ipconfig /renew
  3. Restart your computer once all commands complete.

Troubleshooting tip: If ipconfig /renew returns an error about “media disconnected,” skip it — this is normal for Wi-Fi adapters in certain states and won’t affect the reset result.

Fix 6: Update or Roll Back Your Network Adapter Driver

An outdated or buggy driver can cause intermittent DNS failures. Updating usually fixes it — but if the error started right after a Windows update, rolling back to the previous driver version may be exactly what’s needed.

  1. Right-click the Start button and choose Device Manager.
  2. Expand Network Adapters.
  3. Right-click your Wi-Fi or Ethernet adapter and select Update driver → Search automatically for drivers.
  4. If the error appeared after a recent Windows update, right-click the adapter, choose Properties, open the Driver tab, and click Roll Back Driver.

Fix 7: Temporarily Disable Your Antivirus or Firewall

Some antivirus programs and third-party firewalls intercept DNS requests to scan them — and can accidentally block them instead. Disabling your security software briefly is a safe diagnostic step. Just don’t browse untrusted sites while it’s off.

  1. Right-click your antivirus icon in the system tray (bottom-right corner of your taskbar).
  2. Look for an option like Disable protection, Pause, or Turn off temporarily.
  3. Try loading a website. If it works, your security software is the culprit.
  4. Re-enable protection immediately after the test.
  5. Check your antivirus settings for DNS filtering, “Web Shield,” or HTTPS scanning features and configure an exclusion — or contact the vendor’s support team for guidance.

Common Mistakes to Avoid

  • Pressing the router’s physical Reset button instead of power-cycling it. That button restores factory settings and deletes your Wi-Fi password. Unplug the power cable instead — that’s a power cycle with no side effects.
  • Skipping the “Run as administrator” step in Command Prompt. The ipconfig /flushdns and netsh commands fail silently or return errors without admin privileges. Always right-click and choose Run as administrator.
  • Forgetting to click OK when changing DNS settings. The new DNS servers won’t apply until you click OK in both the TCP/IPv4 Properties and Network Adapter Properties windows. Closing either window without clicking OK discards your changes completely.
  • Testing in the same browser tab after making a fix. Browsers cache their own DNS and page data. Always open a new private/incognito window to test — an existing tab can make you think a fix didn’t work when it actually did.
  • Leaving your antivirus disabled after the diagnostic test. Re-enable your protection immediately once you’re done testing. Never leave your PC unprotected while browsing for longer than a minute or two.
  • Assuming the problem is your PC when every device is affected. If every phone, tablet, and laptop in your home shows the same error, the problem is your router or your ISP — not any individual device. Power-cycle the router first before touching any PC settings.

Frequently Asked Questions

What does “DNS server not responding” mean?
It means your computer sent a request to translate a website name into an IP address, but the DNS server didn’t reply. Without that translation, your browser can’t load websites — even when your Wi-Fi appears to be connected and working.

Why does this error only affect one device?
If other devices on your network work fine, the problem is specific to that computer — likely a corrupted DNS cache, a misconfigured DNS setting, or a driver issue. Start with flushing your DNS cache (Fix 2) and switching to Google’s DNS (Fix 3).

Is it safe to use Google’s public DNS (8.8.8.8)?
Yes. Google’s public DNS (8.8.8.8 / 8.8.4.4) and Cloudflare’s DNS (1.1.1.1 / 1.0.0.1) are free, highly reliable, and trusted by hundreds of millions of users. Either is a solid replacement for your ISP’s default DNS.

Will resetting TCP/IP delete my files or settings?
No. The TCP/IP and Winsock reset only restores Windows’ internal networking rules to their defaults. It has zero effect on your personal files, installed apps, Wi-Fi passwords, or any other settings outside the networking stack.

Can a VPN cause “DNS server not responding”?
Yes. VPNs route your DNS traffic through their own servers, and a misconfigured or failing VPN can trigger this error. Disconnect your VPN and test your connection directly. If the error disappears, check your VPN’s DNS settings or contact their support team.

What if none of the seven fixes work?
Contact your Internet Service Provider. The problem may be a DNS server outage or a fault on their network. If your connection is working but painfully slow rather than dead, our guide on how to fix slow internet on Windows 11 covers additional speed-focused tweaks. Otherwise, your ISP’s support team can run remote diagnostics on their end that you have no way to access yourself.

Does this error mean I have a virus?
Not typically. The vast majority of DNS errors are caused by router glitches, stale cache, or misconfigured settings — not malware. However, some malware does modify DNS settings. If the error keeps returning after you’ve applied all the fixes, run a full scan with Windows Defender or Malwarebytes as a precaution.

Conclusion

The “DNS server not responding” error sounds technical, but it’s almost always fixable without a technician. A router restart, a quick ipconfig /flushdns command, or a switch to Google’s DNS (8.8.8.8) resolves the vast majority of cases in under five minutes. Work through the fixes in order and test after each one — you’ll be back online fast.

Wi-Fi Keeps Disconnecting on Windows 11? 8 Ways to Get a Stable Connection

Fix Wi-Fi that keeps disconnecting on Windows 11 with 8 proven methods — disable power saving, update your driver, reset TCP/IP, and more. Most users fix it in the first 3 steps.

Your Wi-Fi drops mid-Zoom call. You reconnect — and it cuts out again 10 minutes later. If your Wi-Fi keeps disconnecting on Windows 11, you’re not alone. This is one of the most-searched Windows 11 frustrations, and it almost always comes down to a fixable setting or driver issue — not broken hardware.

The usual suspects are a power-saving setting that silently puts your adapter to sleep, an outdated driver, or a corrupted network stack. None of these require a tech background to fix. Work through the 8 steps below in order, and test your connection after each one.

Note: If your Wi-Fi shows “Connected” but pages won’t load, that’s a separate issue — see our guide on Wi-Fi connected but no internet on Windows 11.

Quick Answer

To fix Wi-Fi that keeps disconnecting on Windows 11, open Device Manager > Network Adapters, right-click your Wi-Fi adapter, go to Properties > Power Management, and uncheck “Allow the computer to turn off this device to save power.” Click OK and restart your PC. This single setting resolves the problem for most users.

Why Does Wi-Fi Keep Disconnecting on Windows 11?

Knowing the cause helps you target the right fix first:

  • Power management — Windows puts the Wi-Fi adapter to sleep to save battery, cutting your connection without warning.
  • Outdated or corrupted driver — A bad driver causes random signal drops and disconnections.
  • Roaming aggressiveness — Your adapter aggressively hunts for a “stronger” signal and drops the current one in the process.
  • Corrupted network stack — Damaged TCP/IP settings or a stale DNS cache create ongoing instability.
  • Fast Startup — Windows 11’s Fast Startup can leave the network adapter in a broken state after booting.
  • A recent Windows Update — An update may have replaced a working driver or changed a network setting.

Fix 1: Disable Power Management on Your Wi-Fi Adapter

This is the most common fix — and the quickest. Windows can power down your Wi-Fi adapter automatically to conserve battery, silently dropping your connection.

  1. Right-click the Start button and select Device Manager.
  2. Expand Network Adapters.
  3. Right-click your Wi-Fi adapter (e.g., “Intel Wireless,” “Realtek Wi-Fi”) and choose Properties.
  4. Click the Power Management tab.
  5. Uncheck “Allow the computer to turn off this device to save power.”
  6. Click OK and restart your PC.

Pro tip: On a laptop, also go to Settings > System > Power & sleep > Additional power settings and switch to the High Performance power plan while troubleshooting to prevent Windows from throttling the adapter.

Fix 2: Update or Reinstall Your Wi-Fi Driver

An outdated or corrupted driver is the second most common cause of random drops.

  1. Open Device Manager > Network Adapters.
  2. Right-click your Wi-Fi adapter and choose Update driver.
  3. Select “Search automatically for drivers” and follow the prompts.

If Windows finds nothing new, visit your PC manufacturer’s website (Dell, HP, Lenovo, ASUS, etc.) and download the latest Wi-Fi driver directly — these are always more up to date than what Windows Update provides.

For a full clean reinstall: right-click the adapter, choose Uninstall device, check the box to delete the driver software, then restart. Windows will reinstall the driver automatically on boot.

Troubleshooting tip: If Windows keeps reinstalling an old driver, download the latest driver as a standalone .exe from your manufacturer’s site and run it manually to bypass Windows Update.

Fix 3: Run the Built-in Network Troubleshooter

  1. Go to Settings > System > Troubleshoot > Other troubleshooters.
  2. Click Run next to Internet Connections.
  3. Also click Run next to Network Adapter for a deeper scan.
  4. Follow the on-screen prompts and apply any recommended fixes.

The troubleshooter won’t always find the root cause, but it can catch common misconfigurations and reset certain settings automatically — worth a minute of your time before going deeper.

Fix 4: Reset the TCP/IP Stack and Flush DNS

A corrupted TCP/IP stack or stale DNS cache causes repeated disconnections. Resetting them is completely safe and takes under two minutes. If you suspect your DNS specifically is misbehaving, our guide on the DNS server not responding error on Windows walks through deeper DNS fixes.

  1. Search for cmd in the Start menu, right-click Command Prompt, and select Run as administrator.
  2. Run each command below, pressing Enter after each line:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /flushdns
ipconfig /renew
  1. Restart your PC when done.

Pro tip: This fix is especially effective if your drops started right after a Windows Update, which can silently corrupt DNS or TCP/IP settings in the background.

Fix 5: Change the Roaming Aggressiveness Setting

If your adapter constantly jumps between your 2.4 GHz and 5 GHz bands — or scans for a “better” nearby network — it will drop your current connection in the process. Locking it down stops this.

  1. Open Device Manager > Network Adapters.
  2. Right-click your Wi-Fi adapter > Properties > Advanced tab.
  3. Find Roaming Aggressiveness (may also be called Roaming Sensitivity) in the property list.
  4. Set the value to Lowest or 1.
  5. Click OK.

Pro tip: While you’re in the Advanced tab, check that 802.11n Channel Width is set to Auto. A mismatch with your router’s channel width can cause intermittent drops.

Fix 6: Disable Fast Startup

Windows 11’s Fast Startup speeds up boot times by saving a partial system state on shutdown — but this can leave your network adapter in an inconsistent state each time you power on.

  1. Open Control Panel and go to Hardware and Sound > Power Options.
  2. Click “Choose what the power buttons do” in the left sidebar.
  3. Click “Change settings that are currently unavailable.”
  4. Uncheck “Turn on fast startup” and click Save changes.
  5. Do a full shutdown (Start > Shut down — not Restart) and power back on.

Fix 7: Forget and Reconnect to Your Wi-Fi Network

Corrupted stored credentials or network profile settings can cause repeated drops on reconnect. A clean re-pairing often clears this up.

  1. Go to Settings > Network & internet > Wi-Fi > Manage known networks.
  2. Find your network name and click Forget.
  3. Click your network in the taskbar Wi-Fi menu, enter your password, and reconnect fresh.

Fix 8: Check for — or Roll Back — a Windows Update

A pending update may include a driver fix or patch for your exact issue. But a recent update might also be the cause if drops started shortly after one was installed.

  • To update: Go to Settings > Windows Update > Check for updates and install anything pending.
  • To roll back: Go to Settings > Windows Update > Update history > Uninstall updates. Compare the date your drops started with the install dates shown — a match is a strong signal to remove that update.

If you’re also experiencing system slowdowns alongside the disconnections, check out our guide on Windows 11 keeps freezing — several of the same underlying fixes apply.

Common Mistakes to Avoid

  1. Restarting the router first. If other devices (phone, tablet) stay connected fine, your router isn’t the problem — Windows is. Go straight to Fix 1 instead of wasting time on the router.
  2. Relying on Windows Update for drivers. Windows Update installs older, generic drivers. For the latest and most stable version, always download directly from your PC manufacturer’s website.
  3. Skipping Fix 1. Power management is the root cause for the majority of users, but it’s the most commonly overlooked step. Always try it first — it takes under two minutes.
  4. Not doing a full restart after each fix. Driver reinstalls, TCP/IP resets, and Fast Startup changes only take full effect after a proper restart — not a sleep/wake cycle.
  5. Assuming the hardware is dead. If only your Windows PC drops Wi-Fi while other devices hold a steady connection, hardware failure is almost never the cause. Exhaust all software fixes first. If nothing works, a USB Wi-Fi adapter (under $20) is a fast, cheap way to confirm whether the internal adapter is at fault.

Frequently Asked Questions

Why does my Wi-Fi keep disconnecting on Windows 11 after sleep?

The power management setting is almost always the culprit here. Windows is configured by default to turn off the Wi-Fi adapter during sleep to save battery. Open Device Manager, right-click your Wi-Fi adapter, and uncheck “Allow the computer to turn off this device to save power” in the Power Management tab (Fix 1 above).

Will resetting TCP/IP delete my files or saved passwords?

No. The netsh reset commands only clear network stack configuration. Your personal files, browser passwords, and installed programs are completely untouched.

My Wi-Fi drops only on my laptop — is the adapter failing?

Probably not. When the problem is isolated to one Windows device while others stay connected, it almost always points to a driver or power management issue, not hardware failure. Work through Fixes 1 and 2 before assuming the adapter needs replacing.

How do I find out which Wi-Fi adapter I have?

Open Device Manager and expand Network Adapters. Look for an entry with “Wi-Fi,” “Wireless,” or “WLAN” in the name — that’s your adapter’s full model name. You can use it to find the correct driver on your manufacturer’s website.

Does switching to 5 GHz help with disconnections?

It can, if 2.4 GHz interference from neighboring networks is the cause. If your router broadcasts both bands, try connecting to the 5 GHz network. Keep in mind that 5 GHz has shorter range — if you’re far from the router, you may actually see more drops on 5 GHz, not fewer.

How can I monitor exactly when my Wi-Fi disconnects?

Open Event Viewer (search for it in Start), go to Windows Logs > System, and filter by source WLAN-AutoConfig. Every disconnection is logged with a timestamp and an error code — this can help you pinpoint the pattern and identify the cause.

Conclusion

Random Wi-Fi disconnections on Windows 11 are genuinely frustrating, but they’re almost always fixable without expert help. Start with Fix 1 (disabling power management on your adapter) — it solves the issue for most people in under two minutes. If that doesn’t do it, update your driver, reset the TCP/IP stack, or disable Fast Startup. Each step is safe and quick.

Wi-Fi Shows Connected But No Internet? Here’s How to Fix It on Windows 11

Wi-Fi shows connected but no internet on Windows 11? Follow these 7 proven fixes — flush DNS, reset TCP/IP, change DNS servers, and more. Back online in minutes.

You open your laptop, the Wi-Fi icon shows a solid connection in the taskbar — but every webpage fails to load. No browser works, apps say “no internet,” and you have no idea why. This frustrating situation where Wi-Fi is connected but there’s no internet access is one of the most common problems Windows 11 users face.

The good news: it almost always has a software-side cause — a DNS glitch, a stale IP address, or a confused network adapter — which means you can fix it yourself in minutes without calling your ISP.

This guide walks you through 7 proven fixes, starting with the easiest, so you’re back online as fast as possible.

Quick Answer

If your Wi-Fi shows connected but internet isn’t working on Windows 11, start by restarting your router and PC. If that fails, open Command Prompt as administrator and run: netsh winsock reset, netsh int ip reset, ipconfig /flushdns, then restart. This clears most DNS and TCP/IP issues in under two minutes.

Why Is Wi-Fi Connected But There’s No Internet?

Your device can connect to your router without actually reaching the internet. Think of it like getting into a car that has no fuel — you’re seated and buckled, but going nowhere.

The most common causes are:

  • DNS failure — Windows can’t translate website names (like google.com) into IP addresses.
  • IP address conflict or stale lease — Your PC grabbed a bad or duplicate IP address from the router.
  • Corrupted TCP/IP stack — The core networking software hit an internal error.
  • Router or modem hiccup — The router is running fine but its own internet connection dropped.
  • Outdated or glitched network driver — The Wi-Fi adapter software needs a refresh.

A quick way to narrow it down: check if other devices (phone, tablet) on the same Wi-Fi also have no internet. If they do, the problem is your router or ISP. If only your Windows 11 PC is affected, it’s a local issue — and the fixes below will solve it.

Fix 1: Restart Your Router and Your PC

Before anything else, do this. It solves the problem more often than you’d expect, because it clears the router’s memory and forces both devices to renegotiate the connection cleanly.

  1. Unplug your router (and modem, if they’re separate) from the power socket.
  2. Wait a full 30 seconds — this clears the router’s RAM properly, not just a quick blink.
  3. Plug the modem back in first, wait 60 seconds for it to fully reconnect, then plug in the router.
  4. Restart your Windows 11 PC.
  5. Reconnect to Wi-Fi and test by opening a few websites.

Pro tip: If your router has a dedicated Restart button (not Reset — that wipes settings), use it instead of unplugging. It runs a cleaner restart cycle and takes about the same time.

Fix 2: Run the Windows Network Troubleshooter

Windows 11 has a built-in network diagnostic tool that catches and fixes common problems automatically. It’s not perfect, but it’s fast and worth running before doing anything manual.

  1. Press Windows + I to open Settings.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Click Run next to Internet Connections.
  4. Follow any on-screen prompts and apply the suggested fixes.
  5. Restart your PC when done, then test your connection.

Troubleshooting tip: If the troubleshooter reports “No issues found” but you still have no internet, skip ahead to Fix 3. The built-in tool doesn’t detect DNS corruption or IP conflicts well — those need manual commands.

Fix 3: Flush DNS and Reset TCP/IP (Most Effective Fix)

This is the single most effective fix for “connected but no internet” on Windows 11. It clears the DNS cache (where Windows stores website address lookups) and resets the core networking stack to its defaults — without affecting any of your files or apps.

  1. Click the Start button, type cmd, then right-click Command Prompt and choose Run as administrator. You must run it as administrator or the commands will silently fail.
  2. Type each command below and press Enter after each one:
netsh winsock reset
netsh int ip reset
ipconfig /flushdns
ipconfig /release
ipconfig /renew
  1. Close Command Prompt.
  2. Restart your PC — the resets don’t fully apply until Windows reboots.
  3. Reconnect to Wi-Fi and test.

Pro tip: You can select all five commands, copy them, and paste the whole block into Command Prompt at once. They’ll run in sequence automatically, saving you time.

Troubleshooting tip: If you see “Access denied” on any command, you opened Command Prompt without administrator rights. Close it and redo step 1, making sure to right-click and choose “Run as administrator.”

Fix 4: Change Your DNS Server to Google or Cloudflare

Your ISP’s DNS server can go down, get overloaded, or respond slowly — cutting off internet access even when your Wi-Fi is perfectly fine. Switching to a reliable public DNS server often fixes this instantly and can also speed up browsing. If you’re also seeing an explicit error message, our guide on how to fix the DNS server not responding error on Windows covers more targeted steps.

  1. Press Windows + I, go to Network & Internet > Wi-Fi.
  2. Click your connected network name, then scroll down and click Edit next to DNS server assignment.
  3. Change the dropdown from Automatic to Manual.
  4. Toggle IPv4 on.
  5. Set Preferred DNS and Alternate DNS using the table below.
  6. Click Save and test your connection.
DNS Provider Preferred DNS Alternate DNS Best For
Google 8.8.8.8 8.8.4.4 Reliability and speed
Cloudflare 1.1.1.1 1.0.0.1 Privacy and speed
OpenDNS 208.67.222.222 208.67.220.220 Family-safe filtering

Pro tip: Always set both Preferred and Alternate DNS. If you leave the alternate blank, Windows has no fallback when the primary DNS is temporarily unreachable, which causes intermittent failures.

Fix 5: Update or Reinstall Your Network Adapter Driver

A corrupted or outdated Wi-Fi driver can cause exactly this symptom — showing as connected to the router, but unable to pass real internet traffic. Updating the driver takes less than two minutes.

  1. Right-click the Start button and select Device Manager.
  2. Expand Network adapters.
  3. Right-click your Wi-Fi adapter (look for “Wireless” or “Wi-Fi” in the name) and choose Update driver.
  4. Select Search automatically for drivers and let Windows check for an update.
  5. If no update is found and the problem persists, right-click the adapter again and choose Uninstall device.
  6. Restart your PC — Windows reinstalls the driver automatically on reboot.

Pro tip: If Windows can’t find a newer driver, visit your PC manufacturer’s website (Dell Support, HP Support, Lenovo Support, ASUS Support, etc.) and search for your model number to download the latest Wi-Fi driver directly.

If your Wi-Fi also cuts out randomly rather than just showing no internet, see our guide on how to fix Wi-Fi keeps disconnecting on Windows 11 for additional driver and power-management steps.

Fix 6: Disable IPv6 on Your Network Adapter

Some routers and ISPs don’t fully support IPv6 — the newer internet address format. When Windows 11 tries to use IPv6 but the router can’t handle it properly, you get a “connected, no internet” result. Disabling IPv6 on your adapter is safe, reversible, and often fixes the problem instantly.

  1. Press Windows + R, type ncpa.cpl, and press Enter to open Network Connections.
  2. Right-click your Wi-Fi connection and choose Properties.
  3. In the list, uncheck Internet Protocol Version 6 (TCP/IPv6).
  4. Click OK, then disconnect from Wi-Fi and reconnect.

Troubleshooting tip: If disabling IPv6 makes things worse rather than better, go back into the adapter’s Properties and re-check the IPv6 box to restore it. This fix only helps when IPv6 is the specific cause.

Fix 7: Reset All Windows Network Settings

If none of the above fixes have worked, a full network reset is your final built-in option. It wipes all adapter settings, saved VPN configurations, and proxy settings — giving Windows 11 a completely clean networking slate.

  1. Go to Settings > Network & Internet > Advanced network settings.
  2. Scroll to the bottom and click Network reset.
  3. Click Reset now and confirm the prompt.
  4. Your PC restarts automatically within 5 minutes.
  5. After it restarts, reconnect to your Wi-Fi network — you’ll need to re-enter your Wi-Fi password.

Note: A network reset removes all saved Wi-Fi passwords and VPN app settings. Have your Wi-Fi password ready before you begin. Any VPN software will need to be reconfigured afterward.

Common Mistakes to Avoid

  • Skipping the router restart. Most people immediately jump to advanced fixes when a simple 30-second router restart would have solved it. Always start there — it fixes the problem roughly 30% of the time.
  • Running Command Prompt without admin rights. The netsh and ipconfig commands return “Access denied” or appear to succeed but do nothing without administrator privileges. Always right-click and choose “Run as administrator.”
  • Skipping the restart after Fix 3. The Winsock and TCP/IP resets require a full Windows reboot to take effect. If you skip the restart and immediately test the connection, the fix hasn’t applied yet.
  • Setting only the preferred DNS and leaving the alternate blank. Without a fallback DNS address, any temporary hiccup on your primary DNS server causes another “no internet” outage. Always fill in both fields.
  • Reinstalling the same driver version. Uninstalling and reinstalling an outdated driver just puts the same broken version back. Check the manufacturer’s website for a newer version before uninstalling.
  • Assuming it’s always the ISP’s fault. When only one device has no internet but others on the same Wi-Fi are fine, the ISP is almost never the cause. The problem is local to your PC — and these fixes will resolve it.

Frequently Asked Questions

Why does my Wi-Fi say “connected” but there’s no internet?

Your device successfully connected to the router, but the router either can’t reach the internet itself (ISP or modem issue) or your PC has a local problem like a DNS failure, a stale IP address, or a corrupted network driver. Check whether other devices on the same Wi-Fi have internet — that single test tells you whether the issue is in the router or on your PC specifically.

What does flushing DNS actually do?

DNS flushing clears Windows’ local cache of website-to-IP-address lookups. If that cache holds outdated or corrupted entries, your browser can’t find websites even though the network connection is technically working. Flushing forces Windows to request fresh lookups from the DNS server, solving the problem instantly when DNS corruption is the cause.

Will resetting TCP/IP delete my files or personal settings?

No. Resetting TCP/IP only changes your PC’s network stack configuration — the internal rules Windows uses to send and receive internet data. It has no effect on files, installed apps, browser bookmarks, passwords, or any personal settings. You can run it without worry.

Is it safe to change my DNS to Google or Cloudflare?

Yes, completely safe. Google Public DNS (8.8.8.8) and Cloudflare DNS (1.1.1.1) are among the most widely used DNS servers in the world. They’re typically faster and more reliable than your ISP’s default DNS. You can switch back at any time by setting DNS back to Automatic in your network settings.

What if only one specific website won’t load but everything else works?

That’s a different problem from “no internet.” The site itself may be down, your browser’s cache might be stale (press Ctrl+Shift+Delete to clear it), or the site could be blocked by your DNS filter or ISP. Try opening the same URL in a different browser or in an incognito window to rule out a browser issue before doing anything else.

How do I know if my router or my PC is causing the problem?

Connect another device — a smartphone or tablet — to the same Wi-Fi network. If that device also has no internet, the problem is your router or ISP: restart the router or contact your ISP. If only your Windows 11 PC is affected while other devices work fine, the problem is local to your PC and the fixes in this guide will resolve it. If the second device is an Android phone that won’t join the network at all, our guide on how to fix an Android phone that won’t connect to Wi-Fi can help.

What should I do if none of these seven fixes work?

If all seven fixes fail, suspect a hardware problem with your Wi-Fi adapter or an ISP outage. Run Windows Update first to ensure all system drivers are current. Then call your ISP to check for reported outages in your area. If the adapter itself is failing, a USB Wi-Fi dongle (available for under $15) is an inexpensive temporary fix while you arrange a repair.

Conclusion

The “Wi-Fi connected, no internet” error on Windows 11 is almost always fixable without a technician. Start with a router restart, run the DNS flush and TCP/IP reset commands if that doesn’t help, and switch to a public DNS server if the problem keeps returning. For stubborn cases, updating your network driver or running a full network reset clears the deeper issues.

Slow Internet on Windows 11? 10 Ways to Speed It Up Fast

Is your internet slow on Windows 11? Learn 10 proven fixes to boost your Wi-Fi and Ethernet speed right now. Most users see faster speeds within minutes.

Is your internet running painfully slow on Windows 11? You’re not alone. Thousands of users report sluggish browsing, buffering videos, and laggy downloads after upgrading to Windows 11 — even on fast broadband connections. The good news? You can fix slow internet on Windows 11 in minutes using the steps in this guide, without calling your ISP or hiring a technician.

Whether you’re on Wi-Fi or Ethernet, these 10 tested fixes will help you diagnose and resolve the problem fast. (If your Wi-Fi shows connected but you get no internet at all, that’s a different problem — see Wi-Fi connected but no internet on Windows 11.)

Quick Answer

To fix slow internet on Windows 11, first toggle off Metered connection (Settings → Network & Internet → Wi-Fi), then change your DNS to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) and flush the cache with ipconfig /flushdns. Finally, update your network adapter driver in Device Manager. These steps fix most Windows-specific slowdowns in under five minutes.

Why Is My Internet So Slow on Windows 11?

Before jumping into fixes, it helps to understand why the problem happens. Common culprits include:

  • Outdated or corrupted network drivers
  • Windows Update running silently in the background
  • Incorrect DNS server settings
  • Metered connection settings throttling your speed
  • VPN or background apps consuming bandwidth
  • Router firmware issues or interference

Now let’s fix them one by one.

10 Fixes for Slow Internet on Windows 11

Fix 1: Run the Windows Network Troubleshooter

Windows 11 has a built-in tool that automatically detects and repairs common network issues.

  1. Press Windows + I to open Settings.
  2. Go to System → Troubleshoot → Other troubleshooters.
  3. Click Run next to “Internet Connections.”
  4. Follow the on-screen instructions and apply any suggested fixes.

This takes under two minutes and often resolves DNS errors and adapter conflicts automatically.

Fix 2: Update Your Network Adapter Driver

An outdated driver is one of the most overlooked causes of slow internet on Windows 11.

  1. Right-click the Start button and select Device Manager.
  2. Expand Network Adapters.
  3. Right-click your Wi-Fi or Ethernet adapter and choose Update driver.
  4. Select Search automatically for drivers.
  5. Restart your PC after the update completes.

If Windows doesn’t find a newer driver, visit your laptop or motherboard manufacturer’s website and download the latest driver manually.

Fix 3: Disable the Metered Connection Setting

Windows 11 can throttle your connection to save data if “Metered Connection” is accidentally enabled.

  1. Open Settings → Network & Internet → Wi-Fi.
  2. Click your connected network name.
  3. Toggle Metered connection to Off.

This single toggle has restored full speeds for countless users — check it before anything else.

Fix 4: Change Your DNS Server to a Faster One

Your ISP’s default DNS servers are often slow. Switching to Google DNS or Cloudflare can noticeably improve page load times.

  1. Go to Settings → Network & Internet → Advanced network settings.
  2. Click your active adapter → Edit.
  3. Set DNS to Manual and enter:
    • Preferred DNS: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)
    • Alternate DNS: 8.8.4.4 or 1.0.0.1
  4. Click Save.

If you also see a “DNS server not responding” message, our dedicated guide on fixing the “DNS server not responding” error goes further.

Fix 5: Flush Your DNS Cache

A corrupted DNS cache can slow down every website you visit.

  1. Press Windows + S and search for Command Prompt.
  2. Right-click and select Run as administrator.
  3. Type the following commands, pressing Enter after each:
ipconfig /flushdns
ipconfig /release
ipconfig /renew
netsh winsock reset
  1. Restart your computer.

Fix 6: Disable Background Apps Eating Your Bandwidth

Apps like OneDrive, Windows Update, or cloud backup tools can silently consume your bandwidth.

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. Click the Network column to sort by usage.
  3. Right-click any high-usage background app and select End Task.

To permanently restrict background data, go to Settings → Apps → Installed apps, select an app → Advanced options → set Background app permissions to “Never.”

Fix 7: Reset Network Settings

If multiple fixes haven’t worked, resetting your network stack clears corrupted configurations.

  1. Open Command Prompt as administrator.
  2. Run these commands one by one:
netsh int ip reset
netsh winsock reset catalog
ipconfig /flushdns
  1. Restart your PC.

Fix 8: Adjust Your Wi-Fi Adapter Power Settings

Windows 11 sometimes limits your Wi-Fi card’s power to save battery, reducing speed.

  1. Open Device Manager → Network Adapters.
  2. Right-click your Wi-Fi adapter → Properties → Power Management.
  3. Uncheck “Allow the computer to turn off this device to save power.”
  4. Also go to Settings → Power → Power mode and set it to Best performance.

Fix 9: Change Your Wi-Fi Channel and Band

If you’re on a crowded 2.4 GHz network, switching to 5 GHz dramatically improves speed.

  1. In your taskbar Wi-Fi panel, look for your network listed as 5G (e.g., “HomeNetwork_5G”).
  2. Connect to the 5 GHz band instead of 2.4 GHz.

If your router is old and doesn’t offer 5 GHz, consider upgrading to a dual-band or Wi-Fi 6 router. And if your connection keeps dropping rather than just running slow, see Wi-Fi keeps disconnecting on Windows 11. If your whole PC feels sluggish — not just the network — our guide on how to speed up a slow Windows 11 PC covers the rest.

Fix 10: Disable Windows Auto-Tuning

Windows’ auto-tuning feature can sometimes backfire and throttle TCP speeds.

  1. Open Command Prompt as administrator.
  2. Run: netsh int tcp set global autotuninglevel=disabled
  3. Restart your PC.
  4. Test your speed. If it doesn’t improve, re-enable it: netsh int tcp set global autotuninglevel=normal

Common Mistakes to Avoid

  • Skipping driver updates — This is the #1 overlooked fix.
  • Restarting the router but not the PC — Always restart both.
  • Using a VPN and blaming Windows — VPNs always reduce speed; disable yours to test.
  • Ignoring Windows Update — A pending update can hog bandwidth for hours. Let it finish, then test.
  • Assuming it’s the ISP — Always test on another device first to confirm the issue is Windows-specific.

Frequently Asked Questions (FAQ)

Why is my internet slow only on Windows 11 but fast on my phone?

This confirms the issue is device-specific, not your ISP. Start with Fixes 2, 3, and 4 — driver updates, metered connection, and DNS changes resolve the majority of Windows-specific slowdowns.

Can Windows Update cause slow internet?

Yes. Windows Update downloads large files silently in the background. Go to Settings → Windows Update → Pause updates temporarily while you need full speed.

How do I check my actual internet speed on Windows 11?

Open your browser and go to fast.com or speedtest.net. Run the test and compare the result to your plan’s promised speed.

Will resetting network settings delete my Wi-Fi passwords?

No. Resetting the network stack (Fix 7) does not delete saved Wi-Fi credentials or your personal files.

Does Windows 11 use more bandwidth than Windows 10?

Not significantly. However, Windows 11 has more aggressive background telemetry and update downloads by default. You can reduce this under Settings → Privacy & Security → Diagnostics & feedback.

What if nothing works?

Try creating a new Windows user account and test internet speed there. If it’s fast on the new account, a corrupted user profile is likely the cause. You can also do a Windows network reset via Settings → System → Recovery → Reset this PC (keeping your files).

Conclusion

Slow internet on Windows 11 is frustrating, but it’s almost always fixable without professional help. Start with the quick wins — disabling metered connection, flushing DNS, and updating your network driver — and work through the list until your speeds return to normal.

Actionable takeaway: Run Fix 3 (Metered Connection) and Fix 4 (DNS Change) right now — together, they resolve slow internet for the majority of Windows 11 users within five minutes.
