wireless card problem

My problem started a few months ago when receiving a 651 error code when trying to connect my Dell Inspiron N4010 to an existing connection that works just fine with my other laptop. Finally, in desperation (and many hours of trying things found on the internet), I reinstalled Win 7. Now, I do not have a wireless card showing in the device manager or in the Advanced section of the PhoenixBios.

Any help would be greatly appreciated. Thank you in advance for any suggestions.
