Wi-Fi Keeps Disconnecting on Windows 11? Here’s How to Fix It (8 Proven Fixes)

Fix Wi-Fi that keeps disconnecting on Windows 11 with 8 proven methods — disable power saving, update your driver, reset TCP/IP, and more. No tech skills needed.

Introduction

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The usual suspects are a power-saving setting that silently puts your adapter to sleep, an outdated driver, or a corrupted network stack.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  • Outdated or corrupted driver — A bad driver causes random signal drops and disconnections.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.

  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.

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.
