How to Fix Wi-Fi Keeps Disconnecting on Windows 11 (7 Proven Fixes)

Wi-Fi keeps disconnecting on Windows 11? Use these 7 proven fixes to stop random drops for good — no tech skills needed. Free, built-in Windows tools only.

Your Wi-Fi keeps disconnecting on Windows 11 — mid-call, mid-stream, mid-meeting. You reconnect, and it drops again minutes later. It’s one of the most reported Windows 11 problems, and it costs real time and real patience.

The most common causes are Windows 11’s aggressive power-saving settings shutting down your Wi-Fi adapter, an outdated or corrupted driver, or a stale DNS cache. The fixes below use only built-in Windows tools — free, no downloads required — and most take under five minutes. Work through them in order until your Wi-Fi stays stable.

Quick Answer

To stop Wi-Fi from disconnecting on Windows 11: open Device Manager, find your Wi-Fi adapter under Network adapters, go to the Power Management tab, and uncheck “Allow the computer to turn off this device to save power.” Then update your driver and run ipconfig /flushdns in an admin Command Prompt. These two steps fix the vast majority of cases.

Why Does Wi-Fi Keep Disconnecting on Windows 11?

Before diving into fixes, here are the most common culprits at a glance:

Cause What Happens
Power Management Windows shuts off the adapter to save battery — even on desktops
Outdated or buggy driver A bad update breaks the adapter’s stability
DNS/IP conflict Your PC holds a stale or duplicate network address
Roaming Aggressiveness setting Windows constantly hunts for a “better” signal, causing drops
Corrupted network profile Saved Wi-Fi credentials go invalid
Unreliable ISP DNS Your ISP’s DNS server drops out, breaking the session
Pending Windows updates Network bugs already fixed in updates you haven’t installed

Fix 1: Turn Off Wi-Fi Power Management (Most Common Fix)

This single setting is responsible for the majority of random Wi-Fi drops on Windows 11. Windows automatically powers off your network adapter during idle periods to save energy — even on plugged-in desktops.

  1. Press Windows + X and click Device Manager.
  2. Expand Network adapters and double-click your Wi-Fi adapter.
  3. Click the Power Management tab.
  4. Uncheck “Allow the computer to turn off this device to save power.”
  5. Click OK, then restart your PC.

Pro tip: On a laptop, also go to Control Panel > Power Options, choose High Performance, and click Change plan settings > Change advanced power settings. Under Wireless Adapter Settings > Power Saving Mode, set it to Maximum Performance.

Fix 2: Update or Roll Back Your Wi-Fi Driver

A Windows 11 update can silently corrupt your Wi-Fi driver. Updating usually fixes it — but if the drops started immediately after a Windows or driver update, rolling back is often the faster solution.

To update your driver:

  1. Open Device Manager, right-click your Wi-Fi adapter, and select Update driver.
  2. Choose Search automatically for drivers and follow the prompts.
  3. Restart your PC after the update.

To roll back your driver:

  1. Double-click your Wi-Fi adapter > Driver tab > Roll Back Driver.
  2. Select a reason and confirm.

Troubleshooting tip: If Windows says the driver is already up to date but drops continue, visit your PC manufacturer’s support site (Dell, HP, Lenovo) or your adapter chipset maker’s site (Intel, Realtek) and download the latest driver manually — manufacturer drivers are often newer than what Windows finds automatically.

Fix 3: Flush DNS and Renew Your IP Address

A corrupted DNS cache or a stale IP address can silently cause your connection to drop. This reset takes about two minutes and is completely safe.

  1. Press Windows + S, type cmd, right-click Command Prompt, and select Run as administrator.
  2. Type each command below and press Enter after each one:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /flushdns
ipconfig /renew
  1. Restart your PC once the commands finish.

These commands reset your network stack to factory defaults — they don’t delete files or change your settings beyond the network configuration.

Fix 4: Adjust Wi-Fi Adapter Advanced Settings

Two hidden adapter settings cause Wi-Fi drops that most guides miss: Roaming Aggressiveness (which makes Windows constantly scan for a stronger signal) and Preferred Band (which can lock you onto a congested 2.4 GHz channel).

  1. Open Device Manager and double-click your Wi-Fi adapter.
  2. Click the Advanced tab.
  3. Find Roaming Aggressiveness and set it to Lowest.
  4. Find Preferred Band or Wireless Mode and set it to 5 GHz if your router supports dual-band.
  5. Click OK and restart.

Troubleshooting tip: Advanced settings vary by adapter brand. If you don’t see “Roaming Aggressiveness,” look for similar options like “Minimum Power Consumption” or “Transmit Power” and lower them instead.

Fix 5: Switch to a Faster Public DNS Server

If your ISP’s DNS server is unreliable, your internet session can cut out even when your Wi-Fi signal bar looks perfect. Switching to Google’s or Cloudflare’s free public DNS servers takes two minutes and often solves the problem permanently.

  1. Go to Settings > Network & internet > Wi-Fi, click your current network, then click Properties.
  2. Click Edit next to DNS server assignment and switch from Automatic to Manual.
  3. Enable IPv4 and enter:
    • Preferred DNS: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)
    • Alternate DNS: 8.8.4.4 (Google) or 1.0.0.1 (Cloudflare)
  4. Click Save.

Fix 6: Forget and Reconnect to Your Wi-Fi Network

Windows can get stuck with corrupted saved credentials for your network. Forgetting the network and rejoining from scratch clears this in about 30 seconds.

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

Pro tip: If you use a 2.4 GHz and a 5 GHz network with the same name (SSID), try forgetting both and reconnecting to each separately. Naming them differently (e.g., “HomeNet” and “HomeNet_5G”) prevents Windows from bouncing between them unpredictably.

Fix 7: Reset All Network Settings

If none of the fixes above have worked, a full network reset returns every adapter, protocol, and configuration to its Windows default — the most thorough reset short of reinstalling Windows itself.

  1. Go to Settings > Network & internet > Advanced network settings.
  2. Scroll down and click Network reset.
  3. Click Reset now, confirm, and let your PC restart.
  4. Reconnect to your Wi-Fi network with your password.

Note: This wipes all saved Wi-Fi passwords, VPN connections, and proxy settings. Have your Wi-Fi password written down before you click Reset.

Common Mistakes to Avoid

  1. Only rebooting your router. A router reboot helps temporarily but doesn’t fix a driver or power management issue on your PC. Always check the Windows side first.
  2. Skipping Windows Update. Pending updates often contain network stack fixes and driver patches. Check Settings > Windows Update and install everything before diving deeper.
  3. Setting Roaming Aggressiveness to Highest. This sounds like it would improve stability, but it makes your adapter constantly hop between access points — causing more drops, not fewer.
  4. Assuming power management only affects laptops. Windows 11 applies this setting to all devices, including plugged-in desktops. Always check it.
  5. Running Network Reset without writing down your Wi-Fi password. The reset wipes every saved credential. Being locked out of your own Wi-Fi after the reset is an avoidable headache.
  6. Blaming Wi-Fi when a VPN is running. Some VPN clients interfere with the network adapter. Disable your VPN temporarily to rule it out before troubleshooting deeper.

Frequently Asked Questions

Why does my Wi-Fi keep disconnecting every few minutes on Windows 11?

Power management is the most likely cause. Windows 11 shuts off your Wi-Fi adapter during idle periods to save energy. Fix it in Device Manager: find your Wi-Fi adapter, open its Properties, go to the Power Management tab, and uncheck “Allow the computer to turn off this device to save power.”

Will resetting network settings delete my files?

No. A network reset only removes saved network configurations and passwords. Your personal files, installed apps, and Windows system are completely unaffected.

Why does my Wi-Fi only disconnect when the PC is idle or overnight?

This is the power management setting in action (Fix 1). Windows aggressively powers down your adapter during idle periods. Disabling that setting stops the drops immediately.

Does this work for Ethernet disconnecting too?

Yes. Fixes 1, 2, 3, and 7 all apply to Ethernet adapters. In Device Manager, find your Ethernet adapter and apply the same steps — especially the Power Management tab.

My Wi-Fi shows “Connected” but pages won’t load — is that the same problem?

“Connected but no internet” is usually a DNS or IP conflict rather than a true disconnect. Start with Fix 3 (flush DNS and renew IP) and Fix 5 (change to a public DNS server) for that specific symptom.

Can a VPN cause Wi-Fi to disconnect on Windows 11?

Yes. Some VPN clients conflict with the network adapter driver and cause drops that look like Wi-Fi problems. Temporarily disable your VPN to test — if the drops stop, update or reinstall the VPN client.

What if all seven fixes fail?

If every fix above fails, the issue is likely hardware-level: outdated router firmware, Wi-Fi channel congestion, or a weak signal. Log into your router’s admin panel (usually at 192.168.1.1 in your browser) to check for firmware updates, or contact your ISP to test line quality.

Conclusion

Wi-Fi keeps disconnecting on Windows 11 is one of those problems that sounds mysterious but almost always has a simple fix. Start with Fix 1 — turning off power management — since it solves the majority of cases without any technical knowledge. If you still get drops after that, work through the driver update and DNS flush and you’ll very likely be stable within ten minutes.

How to Fix Windows Update Not Working on Windows 11 (7 Proven Fixes)

Windows Update not working on Windows 11? Use these 7 proven fixes to clear stuck updates, fix error codes, and get protected again — no tech skills needed.

Introduction

Windows Update is stuck. The progress bar hasn’t moved in an hour, you’re seeing a cryptic error code, or the same update keeps failing in a loop. It’s one of the most frustrating problems a Windows 11 user can face — especially when you know those updates include critical security patches.

The good news: Windows Update not working on Windows 11 is almost always fixable without reinstalling Windows. The cause is usually a corrupted download cache, a stalled background service, or a clock sync issue — and every fix below uses tools already built into Windows 11, no downloads needed.

Quick Answer

To fix Windows Update not working on Windows 11, open Settings > Windows Update and click Retry. If that fails, run the built-in Windows Update Troubleshooter (Settings > System > Troubleshoot > Other troubleshooters). For persistent failures, stop the Windows Update service, delete the files inside C:WindowsSoftwareDistributionDownload, restart your PC, and try again. This clears the corrupted cache that causes most stuck or looping updates.

Why Windows Update Fails in Windows 11

Windows Update depends on background services, a local download cache, and a live connection to Microsoft’s servers. Any link in that chain can break:

  • Corrupted update cache — partially downloaded files confuse the updater.
  • Stopped Windows Update service — it sometimes crashes silently.
  • Not enough disk space — updates need 5–10 GB free to download and unpack.
  • Wrong system date or time — causes Microsoft’s server authentication to fail.
  • Paused updates — Windows 11 lets you pause updates for up to 5 weeks; it’s easy to forget.

7 Fixes for Windows Update Not Working on Windows 11

Fix 1: Retry and Check Your Internet Connection

A dropped connection mid-download is a surprisingly common culprit.

  1. Open a browser and confirm you’re connected to the internet.
  2. Go to Settings > Windows Update.
  3. Click Check for updates or Retry.

If your connection keeps dropping, see our guide on fixing slow internet on Windows 11 first.

Troubleshooting tip: Switch from Wi-Fi to a wired Ethernet cable if possible. Wi-Fi drops during a large download often corrupt the update file.

Fix 2: Run the Windows Update Troubleshooter

This built-in tool automatically detects and repairs the most common update problems.

  1. Open Settings (Win + I).
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Windows Update and click Run.
  4. Follow the on-screen prompts.
  5. Restart your PC, then try updating again.

Pro tip: Even if the troubleshooter says it “couldn’t fix the problem,” it often silently repairs a blocked service. Always retry Windows Update after running it.

Fix 3: Check That Updates Aren’t Paused

  1. Go to Settings > Windows Update.
  2. Look for a “Resume updates” button near the top.
  3. Click it if it’s there, then click Check for updates.

This takes 30 seconds and is easy to miss.

Fix 4: Clear the Windows Update Cache

Corrupted files in the update cache are the single most common cause of stuck or looping updates. Clearing them forces Windows to download a clean copy.

  1. Press Win + R, type services.msc, and press Enter.
  2. Find Windows Update, right-click it, and choose Stop.
  3. Do the same for Background Intelligent Transfer Service (BITS).
  4. Open File Explorer and navigate to C:WindowsSoftwareDistributionDownload.
  5. Press Ctrl + A to select all files and delete them. Leave the folder itself in place.
  6. Return to Services, start Windows Update and BITS again.
  7. Go to Settings > Windows Update and click Check for updates.

Troubleshooting tip: If you see a “file in use” error when deleting, restart your PC first — then delete the files before opening any other programs.

Fix 5: Repair System Files with SFC and DISM

Corrupted Windows system files can silently break the update engine. Two command-line tools fix this.

  1. Search for cmd, right-click Command Prompt, and choose Run as administrator.
  2. Type this and press Enter:
    sfc /scannow
    This may take 10–15 minutes.
  3. When it finishes, type this and press Enter (stay connected to the internet):
    DISM /Online /Cleanup-Image /RestoreHealth
  4. Restart your PC and try Windows Update again.

Pro tip: Run SFC first, then DISM. SFC flags the corrupt files; DISM downloads clean replacements from Microsoft’s servers. The order matters.

Fix 6: Correct Your System Date and Time

An incorrect clock causes Windows Update’s security handshake with Microsoft’s servers to fail — often with no useful error message.

  1. Right-click the clock in the taskbar and choose Adjust date and time.
  2. Turn on Set time automatically and Set time zone automatically.
  3. Click Sync now.
  4. Try Windows Update again.

Fix 7: Free Up Disk Space

Windows Update can silently fail if there isn’t enough free space to unpack the update.

  1. Go to Settings > System > Storage.
  2. Click Temporary files and select what can be safely removed.
  3. Click Remove files.
  4. Search for Disk Cleanup in the Start menu, run it, and check Windows Update Cleanup.

Troubleshooting tip: If your drive is nearly full, move large files (videos, downloads) to an external drive or cloud storage before retrying the update.

Which Fix Should You Try First?

Fix Best For Time Needed Difficulty
Retry / Resume Paused updates or minor glitches 1 min Easy
Troubleshooter Most common errors 5 min Easy
Date/time sync Auth errors with no clear cause 2 min Easy
Clear update cache Stuck or looping updates 10 min Moderate
Free disk space “Not enough space” errors 10–15 min Easy
SFC + DISM Persistent error codes 30–60 min Moderate

Common Mistakes to Avoid

  1. Turning off the PC mid-install. Interrupting an update that’s actively installing (not just downloading) can corrupt Windows. Watch for drive activity before giving up.
  2. Ignoring error codes. Codes like 0x80070002 or 0x800f0922 each point to a specific fix on Microsoft’s support site. Don’t skip them.
  3. Deleting the SoftwareDistribution folder itself. Only delete the files inside SoftwareDistributionDownload. The folder must remain.
  4. Updating over a metered connection. Windows 11 blocks large updates on metered connections (mobile hotspots). Go to Settings > Network > your connection and disable “Metered connection” temporarily.
  5. Skipping restarts. Most fixes only take effect after a full reboot. Don’t assume a fix failed just because you haven’t restarted yet.
  6. Using third-party “PC optimizer” tools. Many of these disable Windows Update services. Check Services.msc and confirm Windows Update is set to Automatic (Delayed Start).

Frequently Asked Questions

Why does Windows 11 say “Update failed” with no explanation?

The most likely cause is a corrupted update cache or a stopped service. Run the Windows Update Troubleshooter first, then try Fix 4 (clearing the cache) if the troubleshooter doesn’t resolve it.

How long should a Windows 11 update take?

Security updates typically take 5–20 minutes. Major feature updates can take 30–90 minutes depending on your PC and internet speed. If the same percentage hasn’t changed in over 2 hours with no drive activity, a restart is safe.

Is it safe to skip Windows Updates?

Short term, yes. Long term, no — especially security patches. Unpatched systems are actively targeted by malware. Update as soon as you can fix the error.

What does Windows Update error 0x80070005 mean?

It’s a permissions error, usually caused by a third-party antivirus blocking the update. Temporarily disable your antivirus, retry the update, then re-enable it. If that works, add Windows Update to your antivirus exclusions.

Can I manually download Windows 11 updates?

Yes. Visit the Microsoft Update Catalog (catalog.update.microsoft.com) and search for the KB number shown in Windows Update. You can download and install it directly as a workaround while you troubleshoot the automatic updater.

Why does Windows Update keep restarting and never finishing?

This restart loop is almost always a corrupted cache (Fix 4) or broken system files (Fix 5). Run both fixes in sequence, then do a clean restart.

Will clearing SoftwareDistribution delete my personal files?

No. It only removes Windows Update’s temporary download files — not your documents, photos, or installed apps. Nothing personal is affected.

Conclusion

Windows Update not working on Windows 11 is almost always fixable with the tools Windows already gives you. Start with the Troubleshooter and cache clear (Fixes 2 and 4) — those two steps alone solve the majority of cases. For stubborn failures, SFC and DISM (Fix 5) go deeper and repair the system files that block updates from completing.
