atheros ar5b91 not detected vista

Specs: Windows Vista
Running Vista and cannot connect to the internet through the Atheros AR5B91. Can connect via USB adapter and LAN cable plugged in to router. Network discovery was custom, for some reason, but turned it off. Everything else in the house works, iphones, xboxes and another laptop with the same Atheros adapter. Any ideas.

Are there any errors shown in Device Manager under Network Adapters?
If yes, re-install the driver for the Atheros adapter.
You can download it from the laptop maker's support website.

Hi and thanks for your reply. Everything is fine in the device manager and it says that it is working correctly. I have rolled back the driver and updated but no good. When you do a network search it does not even appear. I will uninstall the adapter and see what happens. If that does not workt I will uninstall then reinstall Vista. Once I have done that upgrade to Windows 7.
