Performing a Network Reset
Press Start and click the Settings button (or just by pressing Windows+I on your keyboard). On the Windows Settings screen, click “Network & Internet.”
On the “Network & Internet” page, select the “Status” tab on the left and then, on the right, scroll down and click the “Network reset” link.
The “Network reset” screen warns you about what will happen when your network is reset and also lets you know that a restart will be necessary. Click the “Reset now” button to reset the network and restart your PC.
And that’s all there is to it. After restarting your PC, Windows will walk you through setting up your network. It will pretty much just ask if you want your PC to be discoverable and entering in the WiFi password.
