How Did My Computer Forget My Wi-Fi Network?

My computer suddenly forgot my usual Wi-Fi network, and now I can't connect automatically even though it worked perfectly before. I've tried restarting the computer and router, but the network either...

This usually happens because of a Wi-Fi driver issue, a Windows update, a corrupted saved network profile, or a router setting change.

 

Try these fixes in order

Forget and reconnect: Go to Settings → Network & internet → Wi-Fi → Manage known networks, select your network, choose Forget, then reconnect and enter your password.

 

Check whether the network appears: If it doesn't, restart the Wi-Fi adapter under Settings → Network & internet → Advanced network settings.

 

Update the Wi-Fi driver: Open Device Manager → Network adapters → right-click your Wi-Fi adapter → Update driver.

 

Check the router: Make sure Wi-Fi is enabled and the network name (SSID) hasn't changed.

 

Prevent recurrence: Install reliable Windows and Wi-Fi driver updates.

 

Important: If other devices can see your Wi-Fi but your computer cannot, the issue is more likely with your computer's adapter or settings.
