I am having a very similar problem. Each time I connect to any wireless network (secure or unsecure), every goes smooth and I get connected, but only stay connected for a ouple seconds. I tried this code:
Code:
update-rc.d wicd defaults
/etc/init.d/wicd start
startx
After issuing those command, and once the GUI loads, I am able to connect for about 10 minutes, then I have the same problem all over again.
I am using a Broadcom BCM4312 wireless card and BackTrack 5. Any help would be great!
