Hi all back track 3 Rulez

I have been following a tutorial step by step trying to crack my own wireless network WEP key using aircrack-ng tools.

I have a broadcom chipset which I知 not sure is compatible but i can receive many networks in the wireless assistant and it appears to be going in and out of monitor mode smoothly

the problem is when i airodump-ng (interface) all the network i can i see have PWR 0 and some even -1 which is quite strange because generally i get good signals from my neighbours and excellent signals from my own network.

Also I noticed that while i do some airmon-ng commands i get disconnected from the internet and cannot see ANY wireless networks in the wireless assistant all of a sudden.

I知 a new user so any explanation in somewhat easy language would be great!
