Method 1=Your computer should be restarted. Restarting is a common troubleshooting procedure for most electrical devices, and it may be all that's required to resolve the Windows 11 network issue.

Restarting from the desktop is as simple as right-clicking the Start button and selecting Shut down or sign out > Restart.

Method 2=Check that Wi-Fi is turned on or that the Ethernet wire between the computer and the modem/router is securely connected. This is critical, and if it isn't resolved, you won't be able to connect to the internet.

To enable Wi-Fi, certain laptops feature a physical switch that must be toggled. Others utilize FN+F5 or FN+F2 as a key combination. In Settings: Network & Internet > Wi-Fi, there's also a Wi-Fi toggle.
