Killer wireless-N 1103 connectivity problems

Hello,

I have a Alienware M17 R3 laptop with the 1103 wireless card running windows 7.  Until recently I have not had reason to use the Wi-Fi, though when I enabled the card I found that I could not detect any nearby networks.

I have checked the device manager for errors and have found none.  I have noticed that the BigFoot connenction manager does not seem to detect the network card.

Should I reinstall the card driver and the BigFoot helper?

What software might conflict with the wi-fi card?  What services should I check to make they are running?

Thanks,

Derek
