I recently installed BackTrack5-GNOME-64bit to my HDD (First time user) and I can't connect to my WiFi. I am pretty new to linux.
It scans fine and finds the networks but when I try to connect to my Wifi through Wicd it says
My device is
Disconnecting active connections...
ESSID: Resetting IP address...
ESSID: Putting interface up...
ESSID: Validating authentication...
ESSID: Connection Failed: Bad password
I've read on wireless.kernel.org that there is a known issue with DMA (Don't know what that is) and LP-PHY devices with kernel 2.6.
lspci -vnn | grep 14e4
0c:00.0 Network controller : Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
My kernel is 2.6.38 (uname -r).
I have seen some people make the BCM4312 work but I have looked on alot of different methods (Before I reinstalled) and nothing have worked.
Some output (I don't know what most of these report so some might be abundant):

All I have done since my fresh install is download the firmware-b43-lpphy-installer and installed it.
# This file lists those modules which we don't want to be loaded by

My two b43 packages are:
firmware-b43-lpphy-installer (version: 18.104.22.168-4)
b43-fwcutter (version: 1:013-2)
I either would like some insight on how I can fix this problem (if possible) or help with / link to documentation to upgrade the kernel to 3.0. I have searched how to do this but didn't find anything.
If I would go the path of upgrading the kernel, is it a daunting task? Is it smart at all? - I mean is it reasonably stable or is it in early early development? (I don't know much about these matters).
Thanks for any help or advice in advance,
