WiFi Keeps Disconnecting: The Complete Fix

Published 2026 · 3 min read

Repeated disconnects are either one device's power-saving settings or a network-wide problem. The single most common culprit on Windows: the WiFi adapter turning itself off to save power.

1. Stop Windows from sleeping the adapter

Device Manager → Network adapters → your WiFi adapter → Properties → Power Management → uncheck "Allow the computer to turn off this device to save power." This fixes most laptop disconnects.

2. Forget and reconnect

Forget the network, re-enter the password, and update the adapter driver.

3. Network-wide drops

Restart the router and modem, update the router's firmware, and change the WiFi channel or switch to 5GHz if the 2.4GHz band is crowded. An old router (5+ years) often needs replacing.

4. Distance-related drops

That's signal strength — a mesh system or extender covers dead zones.

Why Wi-Fi drops but does not disappear

Intermittent drops usually come from Wi-Fi power management on the adapter, router channel congestion, or the adapter being pushed between 2.4 and 5 GHz bands. Each has a distinct fix, so test the cheap ones first.

Turn off adapter power saving

Open Device Manager > Network adapters > your Wi-Fi adapter > Properties > Power Management and uncheck "Allow the computer to turn off this device." This single setting clears a large share of random drops on laptops.

Pick a stable band and channel

In the router settings, set the 2.4 GHz channel to 1, 6 or 11 (they never overlap) and try forcing the device onto 5 GHz if you are close to the router, or 2.4 GHz if you are far. A channel crowded by neighbors is a common cause of periodic disconnects.

Update the driver and test the router

Update the Wi-Fi driver from your laptop maker's site. If several devices drop at once, reboot the router; if only this device drops, the fault is on the device side.
