How to Fix When Windows 11 Is Stuck in Airplane Mode

Solution 1: Restart the computer. In many circumstances, a tech problem that doesn’t have a clear cause, can be resolved with a simple reboot. One way to restart Windows 11 is to choose Restart from the power menu on the bottom-right side of the Start menu.

Solution 2: Try turning off Airplane mode a different way, like from within Settings (get there with WIN + i). You can find it in the Network & internet section.

Solution 3: If Settings is how you always disable Airplane mode, try instead from the desktop. Select the volume/network area next to the clock, and then select the Airplane mode button.

Solution 4: Disable and then enable the Airplane Mode Switch Collection device in Device Manager (if you see it; not all computers have one). Doing this should refresh Windows 11’s awareness of Airplane mode, letting you disable it normally.To do this, open Device Manager, expand the Human Interface Devices category, and then disable the device by
right-clicking it and choosing Disable device. Once it’s fully disabled, right-click it once more and choose Enable device.

Solution 5: Run the built-in network adapter troubleshooter to have Windows attempt to identify and fix the problem automatically.
Get there through Settings: System > Troubleshoot > Other troubleshooters. Select Run next to Network Adapter.
