Please check if the wireless driver is detected in the device manager. Click on the Windows flag (start) icon, type Device Manager and check for Wireless driver under Network Adapters.
Let's try these steps to resolve the issue:

When complete, follow any recommended actions and try connecting again.
If problem persists or there were no issues found by the troubleshooter, close the results screen and continue to the next step.
