If Wi-Fi keeps disconnecting on Windows 11, the problem may be caused by the router, wireless driver, signal interference, power management, or network settings. Try these fixes in order.
1. Restart the router and PC
Restart your router and wait until the connection is fully restored. Then restart Windows and test the Wi-Fi connection.
2. Check the Wi-Fi signal
Move closer to the router and test the connection. If the problem disappears near the router, distance or interference may be contributing to the issue.
3. Forget and reconnect to the network
- Open Settings → Network & internet → Wi-Fi.
- Open Manage known networks.
- Select your network and choose Forget.
- Reconnect and enter the Wi-Fi password.
4. Update the Wi-Fi driver
Open Device Manager, expand Network adapters, and update the wireless adapter. You can also check the PC manufacturer’s official support page for a compatible driver.
5. Check power management
Open the wireless adapter properties in Device Manager and review its power management options. If Windows is frequently turning the adapter off, test whether changing the available power-saving setting improves the connection.
6. Reset network settings
If the problem persists, use Settings → Network & internet → Advanced network settings → Network reset. You will need to reconnect to saved networks afterward.
Final thoughts
Start with the router, signal, and Wi-Fi driver. Use a network reset only after simpler connection and driver checks have failed.
