Why does my WiFi keep disconnecting in Windows 11?

The most common causes of random WiFi disconnections in Windows 11 are: power management turning off the adapter, an outdated or corrupted WiFi driver, router channel congestion, or the network profile getting corrupted. Disabling power management on the adapter and updating the WiFi driver resolves the issue for most users.

How do I stop WiFi from disconnecting randomly in Windows 11?

Open Device Manager, find your WiFi adapter, double-click it, go to Power Management tab and uncheck Allow computer to turn off this device to save power. Also go to the Advanced tab and set Roaming Aggressiveness to Medium. These two changes prevent most random WiFi disconnections.

Can a Windows 11 update cause WiFi to keep disconnecting?

Yes. Windows updates frequently overwrite WiFi drivers or reset power management settings, causing random disconnections. Reinstalling the WiFi driver from your manufacturer website and disabling adapter power management together fix update-caused disconnection issues.

Why does WiFi disconnect every few minutes in Windows 11?

WiFi disconnecting every few minutes usually indicates either power management aggressively turning off the adapter, router channel congestion causing signal drops, or a corrupted network profile forcing reconnection cycles. Fix 1 (power management), Fix 5 (router channel) and Fix 3 (forget and reconnect) address these three causes.

Does router channel congestion cause WiFi disconnections in Windows 11?

Yes. If many nearby networks are using the same WiFi channel (especially on 2.4GHz), signal interference causes frequent disconnections. Log into your router settings and change the WiFi channel to 1, 6, or 11 on 2.4GHz, or switch to 5GHz band which has far less congestion.
