The network reset tool is found on the Network & Internet screen.
Expand the Start Menu and search for
Settings. Open the Settings window and choose Network & Internet.
In the left-hand column, Status should be selected. If it isn't, select it.
At the bottom of the Change your network settings list, choose Network Reset.
Select Reset Now to initiate the reset process. Be sure to choose Yes on the prompt confirming the reset.
When the reset is complete, your computer will restart. All of the network adapters will be reinstalled and network settings returned to their default values. This process might uninstall VPN or virtual switch software. With everything wiped, you can start a new network connection.
If the issue doesn't resolve you may need to reset the router of the network you're using. Worst case, you may want to try restoring Windows 10 to a previous state.
There are so many new features in Windows 11 it's almost hard to keep up with them all.
