1) Try opening up Device Manager on an Administrator account:
2) Go to Network Adapters > Right click your Wi-Fi one > Uninstall device > Don't check off the box to delete driver > Uninstall
3) Restart your device and try to connect.
If this doesn't work, do the same, but check off the box delete driver. Go to your devices website and look for the Wi-Fi driver and install it. (If you have a Dell, go to the Dell website and put in your device serial number as an example).
My best guess is this is a driver issue.
