Just installed Backtrack 5r3 to the harddrive of a Samsung NP520U4C-A01UB, with an Intel® Centrino® Advanced-N 6235 wireless card, but I can't seem to get it working. After iwconfig, I get the following:

lo             no wireless extensions

wlan0       IEEE 802.11ABGN ESSID:off/any
               Mode:Managed Access Point: Not -Associated Tx-Power0 dBM
               Retry  long limit:7 RTS thr:off  Fragment thr:off
               Encryption key:off
               Power Management:off

eth0         no wireless extensions
In the Wicd Network Manager, the network tab displays "No wireless networks found." Under the preferences tab, in the general settings tab, the wireless interface is listed as wlan0.

Any help would be greatly appreciated.
