NOTE: I have tested the most information about how to start, disconnect etc with an atheros card but i still have problem.

Computer: HP Pavillion 9000
Card: Ubiquiti SRX Express card 34

I have following problem:

1. I put the Backtrack 3 LiveCD/xploitz USB fix and choose the KDE.
2. It starts to boot up with alot of text you know but after a while after it has loaded som "HAL" something i got this error:
Bank 0: b20000400000800
Bank 5: b200121020080400
Kernel panic - not syncing: CPU context corrupt
3.And i have to restart the computer.

But there is one way to avoid it, just some seconds before that sequens i pull out my Ubiquiti SRX from the Express card slot and then re-insert it --> KDE boots up fine and i reach the desktop.

Then i start the wireless assistent to connect to my essid "dlink", but i only got Connection failed.

IWCONFIG gives me this:
bt ~ # iwconfig
