Fix Windows 11 Wi-Fi Keeps Disconnecting

What Causes This?

Windows 11 Wi-Fi disconnects are usually caused by a bad network driver, aggressive power-saving settings, or router compatibility issues. In some cases, background apps, VPNs, or outdated Windows updates interfere with the wireless adapter and cause random dropouts. Corrupted network settings can also make the connection unstable even when your internet service is fine.

Common Symptoms

• Wi-Fi disconnects every few minutes and reconnects on its own
• The network shows “Connected, no internet” or disappears temporarily
• Video calls, games, or downloads suddenly drop
• Wi-Fi works after a restart, then becomes unstable again
• Other devices stay connected while your Windows 11 PC keeps dropping

How to Fix It Manually

1. Restart your PC and router

   • Restart your computer from Start > Power > Restart.
   • Unplug your router and modem for 30 seconds, then plug them back in.
   • Wait a few minutes and test the connection again.
   • If only your PC has the issue, continue with the steps below.

2. Run the Windows network troubleshooter

   • Press Windows key + I to open Settings.
   • Go to System > Troubleshoot > Other troubleshooters.
   • Find Network and Internet and click Run.
   • Apply any fixes Windows suggests, then reconnect to Wi-Fi.

3. Stop Windows from turning off your Wi-Fi adapter

   • Right-click Start and select Device Manager.
   • Expand Network adapters.
   • Right-click your Wi-Fi adapter and choose Properties.
   • Open the Power Management tab.
   • Uncheck Allow the computer to turn off this device to save power.
   • Click OK and restart your PC.

4. Update or reinstall the Wi-Fi driver

   • Open Device Manager again.
   • Expand Network adapters and right-click your wireless adapter.
   • Click Update driver > Search automatically for drivers.
   • If Windows says the best driver is already installed, go back, right-click the adapter, and choose Uninstall device.
   • Check Attempt to remove the driver for this device if the option appears, then click Uninstall.
   • Restart your PC. Windows will reinstall the adapter automatically.
   • You can also download the latest Wi-Fi driver directly from your laptop or motherboard manufacturer for a more reliable fix.

5. Reset your network settings

   • Press Windows key + I to open Settings.
   • Go to Network & internet > Advanced network settings > Network reset.
   • Click Reset now.
   • Your PC will restart after a few minutes.
   • Reconnect to your Wi-Fi network by entering the password again.

6. Disable background apps, VPNs, and bandwidth-heavy tools

   • Press Ctrl + Shift + Esc to open Task Manager.
   • Look for VPN apps, third-party firewall tools, cloud sync apps, or download managers that may interrupt the connection.
   • Select any unnecessary app and click End task.
   • If you use a VPN, disconnect it temporarily and test Wi-Fi stability.
   • Also check Settings > Windows Update and install any pending updates.

7. Change adapter settings if disconnects continue

   • In Device Manager, right-click your Wi-Fi adapter and choose Properties.
   • Open the Advanced tab.
   • Look for settings like Roaming Aggressiveness, Wireless Mode, or Preferred Band.
   • Set Preferred Band to 5 GHz if your router supports it, or try 2.4 GHz if range is the issue.
   • Lowering Roaming Aggressiveness can also reduce random disconnects on some laptops.
