We had a Windows 8.? computer at a quick build a couple of years ago with a similar issue. The operator selected Public from the list of network location choices (Home, Work or Public) this caused it to block the IP of the wireless connection on the router.

Depending on the Windows version, this can be difficult to diagnose and reset to allow it.

Search for "how to change network location to private" and follow instructions based on Windows version.
