The fix to the error you can find oh the Wiki as for you adapter we can't help you unless you give more details.
Hello! Backtrack have worked perfect on my latpot for a good time now, but suddenly out of nowere it stop detecting my wlan. The most wired think about all of this is that if i enter wicd network manager, I can still find my wlan and connect to it. But no matter what I does in Wicd, I can get my laptop online.
There is also an error while starting Wicd. "Could not connect to icd's D-Bus interface. Check the wicd log for error messages." I have no idea where I can find this error log.
Im using a HP laptop with integrated Boardcom wlan chip.
