If it is enable or enabling it does not work then I would try 2 more things:
On your PC go to the Network and Sharing Centre in Control Panel and click Manage Wireless connections and delete your old connection.
Then go on the router and remove an Password on the wirless and set it to open. Save it and reboot the router.
Reboot the computer and then see if you can get on. If you can add back the security on the router.
It was enabled. I just tried removing the password to get on, reset it and it still does not show anywhere.
