Bluetooth Keeps Disconnecting on Windows 11? How to Fix It

Your Bluetooth headphones, mouse, or keyboard keeps disconnecting and reconnecting on Windows 11, or drops out for a few seconds at a time.

Why: Most drops come from interference and weak signal, a low battery, or a stale pairing — and sometimes a power-saving setting that quietly switches the radio off. These fixes go fastest-first.

Fix 1: Reduce interference and charge the device

Bluetooth shares the crowded 2.4 GHz band, so distance and obstacles cause the dropouts most people see.

1. Move the device closer to the PC and clear the line of sight — walls, metal desks, and USB 3.0 hubs all weaken the signal.
2. Keep it away from Wi-Fi routers, microwaves, and other wireless gear while testing.
3. Fully charge the device (or swap in fresh batteries), then power it off and back on.

Fix 2: Toggle Bluetooth, then remove and re-pair

A clean re-pair clears a corrupted saved connection, which is a common cause of repeated drops.

1. Open Quick Settings from the taskbar (Network/Sound/Battery icons), select the Bluetooth tile off, wait 10 seconds, and turn it back on.
2. If it still drops, select Start > Settings > Bluetooth & devices > Devices, choose More options (the three dots) next to the device, then Remove device and confirm.
3. Put the device back in pairing mode and add it fresh: select Add device > Bluetooth.

Fix 3: Restart the Bluetooth Support Service

The service that manages discovery and connections can hang; restarting it restores stable links without a reboot.

1. Press Windows + R, type services.msc, and press Enter.
2. Find Bluetooth Support Service, right-click it, and select Restart.
3. Double-click it, set Startup type to Automatic, then select OK.

Fix 4: Stop Windows turning off the Bluetooth radio

Power management can shut the Bluetooth adapter off to save energy, which shows up as random disconnects.

1. Select Start > Device Manager, expand Bluetooth, and double-click your adapter (the main one, not the device).
2. On the Power Management tab, clear Allow the computer to turn off this device to save power, then select OK.
3. While there, on the Driver tab choose Update driver > Search automatically for drivers, then restart.

FAQ

Only my headphones drop, other devices are fine. That points to the headphones’ battery or firmware — charge them, update their firmware via the maker’s app, and re-pair (Fix 2).

It disconnects when the laptop sleeps or idles. That’s almost always power management — turn off the “save power” option on the adapter (Fix 4).

Everything drops at once. Suspect the PC’s adapter or driver: restart the Bluetooth Support Service (Fix 3), update the driver, and install pending Windows updates.
