Fix Wi-Fi Keeps Disconnecting on Windows 11

If your Windows 11 PC keeps dropping Wi-Fi, the fix usually involves updating your wireless driver, changing the power management setting for the adapter, or resetting the network stack. This guide walks through the most effective solutions in order, from quick checks to more advanced resets.

Why Windows 11 Wi-Fi Drops Randomly

Windows 11 is generally stable, but Wi-Fi disconnects can happen for many reasons. The most common culprits are outdated or buggy wireless drivers, aggressive power-saving features that turn off the adapter, and interference from other devices. Sometimes the problem is with the router or the internet service provider, but if your phone stays connected while your PC drops, the issue is almost certainly on the PC side.

Other frequent causes include:

• Wi-Fi adapter power management – Windows may put the adapter to sleep to save battery.
• Driver conflicts – a recent Windows update or a new driver can break things.
• IP address conflicts – two devices on the same network with the same IP.
• Wireless interference – microwaves, cordless phones, or neighboring networks on the same channel.
• Router settings – band steering, channel width, or firmware bugs.

Before You Start: Quick Checks

Try these simple steps first. They take less than a minute and solve a surprising number of cases.

1. Restart your PC and your router (unplug both for 30 seconds).
2. Forget the Wi-Fi network and reconnect: Settings > Network & internet > Wi-Fi > Manage known networks, select the network, and click Forget. Then reconnect by entering the password again.
3. Move closer to the router to rule out range issues.
4. Check if other devices (phone, tablet) also drop. If they do, the problem is likely the router or ISP, not your PC.

Fix 1: Update or Reinstall Your Wi-Fi Driver

An outdated or corrupted driver is the #1 cause of Wi-Fi disconnects on Windows 11. Here’s how to update it:

1. Press Win + X and select Device Manager.
2. Expand Network adapters.
3. Right-click your Wi-Fi adapter (it usually has “Wireless� or “Wi-Fi� in the name) and select Update driver.
4. Choose Search automatically for drivers. If Windows finds nothing, go to your PC or adapter manufacturer’s website and download the latest driver manually.

If updating doesn’t help, try uninstalling the driver and letting Windows reinstall it:

1. In Device Manager, right-click the adapter and select Uninstall device.
2. Check the box Delete the driver software for this device and click Uninstall.
3. Restart your PC. Windows will automatically install a fresh driver.

Fix 2: Disable Wi-Fi Power Saving

Windows 11 has a power-saving feature that can turn off your Wi-Fi adapter to save battery. This is a common cause of disconnects, especially on laptops.

1. Open Device Manager.
2. Right-click your Wi-Fi adapter and select Properties.
3. Go to the Power Management tab.
4. Uncheck Allow the computer to turn off this device to save power.
5. Click OK.

Also, check the power plan settings: Control Panel > Power Options > Change plan settings > Change advanced power settings. Look for Wireless Adapter Settings > Power Saving Mode and set it to Maximum Performance.

Fix 3: Run the Network Troubleshooter

Windows 11 includes a built-in troubleshooter that can automatically detect and fix common network problems.

1. Go to Settings > System > Troubleshoot > Other troubleshooters.
2. Find Network and Internet and click Run.
3. Follow the on-screen instructions. It may reset your network adapter or flush DNS.

This doesn’t always fix the issue, but it’s worth trying because it’s quick and sometimes catches something you missed.

Fix 4: Reset Network Settings (and Winsock)

If the above fail, resetting the network stack can clear corrupted settings. This will remove all saved Wi-Fi networks and VPN connections, so have your passwords handy.

1. Open Settings > Network & internet > Advanced network settings.
2. Click Network reset.
3. Click Reset now and confirm. Your PC will restart.

You can also try the command-line approach:

1. Open Command Prompt as administrator (search “cmd�, right-click, and select “Run as administrator�).
2. Type the following commands, pressing Enter after each:
   netsh winsock reset
netsh int ip reset
3. Restart your PC.

Fix 5: Change Wi-Fi Band or Channel

Interference from other networks can cause disconnects. If you’re on a crowded 2.4 GHz band, try switching to 5 GHz or vice versa. You can do this from the router’s settings page (usually accessed via a browser at an address like 192.168.1.1). Look for “Wireless settings� and change the band or channel.

On Windows 11, you can also set the adapter to prefer a specific band:

1. Open Device Manager, right-click the Wi-Fi adapter, and select Properties.
2. Go to the Advanced tab.
3. Find Preferred Band and set it to Prefer 5 GHz (or 2.4 GHz if you’re far from the router).

If you’re not comfortable changing router settings, you can also try moving the router to a more central location or away from walls and appliances.

Fix 6: Disable IPv6 (Sometimes)

IPv6 can occasionally cause disconnects if your router’s IPv6 implementation is buggy. Disabling it is a safe test:

1. Open Control Panel > Network and Sharing Center > Change adapter settings.
2. Right-click your Wi-Fi adapter and select Properties.
3. Uncheck Internet Protocol Version 6 (TCP/IPv6).
4. Click OK and restart.

If the disconnects stop, you can leave it off or update your router firmware.

Frequently Asked Questions

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

Windows 11 has different power management defaults and driver models than Windows 10. A driver that was fine on Windows 10 may be buggy on Windows 11. Also, Windows 11’s “Memory Integrity� (Core Isolation) can conflict with some older drivers. Try updating the driver first, then check power settings.

How do I know if it’s a driver problem or a router problem?

Check if other devices stay connected. If they do, it’s likely your PC. Then look at the Windows Event Viewer (under “Windows Logs > System�) for errors with source “WLAN-AutoConfig� or “Netwtw� – these often point to driver issues. If the disconnects happen at the same time every day, it might be interference from a neighbor’s device.

Will resetting Windows 11 fix Wi-Fi disconnects?

Sometimes, but it’s a last resort. A full reset reinstalls Windows and all drivers, which can clear any corrupted system files. However, it’s time-consuming and you’ll lose installed apps. Try the steps above first.

Does Windows 11 have a known Wi-Fi bug?

Microsoft has acknowledged several Wi-Fi-related bugs in Windows 11 over time, often fixed by cumulative updates. Always make sure Windows Update is current. If a new update causes disconnects, you can uninstall it temporarily from Settings > Windows Update > Update history > Uninstall updates.

Can my antivirus or VPN cause Wi-Fi drops?

Yes. Some security suites include “Wi-Fi protection� or “network shield� features that can interfere. VPNs can also cause disconnects if the tunnel drops. Try disabling your VPN or temporarily turning off your antivirus (if safe) to see if the problem stops.

Is there a way to keep Wi-Fi from disconnecting when the PC sleeps?

Yes. In Settings > System > Power & battery, set “Sleep� to “Never� for both battery and plugged in. Also, in Device Manager, under the Wi-Fi adapter’s Power Management tab, uncheck “Allow the computer to turn off this device to save power.� This is the most common fix for disconnects after waking from sleep.
