I recently bought a D-Link DWA 643 to try out Aircrack using Backtrack 3.
According to a number of sites, this card is compatible with Aircrack, and I *think* that the drivers are bundled with Backtrack 3. But when I plug in the card (it's an Expresscard), Backtrack does not see it (according to iwconfig), and it will not boot at all if the card is plugged in. I've tried booting in safe mode and the system hangs just after "pci interrupt 0000 01 0a.0[a]".
My laptop is a Fujitsu Siemens Amilo M1450G.
Can anyone suggest how I could get Backtrack to recognise this card?
I should also explain that I am a total newbie to Linux, so I'd greatly appreciate if you could answer as if you were speaking to a five-year old!
