I noticed when using airodump-ng in bt4 that I didn't pick up as many networks as i did on bt3 final. It's like my cards signal isn't as strong on bt4 as it is on bt3. I did a test to see which backtrack picked up the most networks bt3, or bt4, and bt3 wins hands down. The down fall is that under bt3 my card doesn't support injection. I know I could patch the driver I just wanted to point that out to the team. Thank you!!

P.s I was not attempting to crack any ones wep/wap it's just I noticed it when I scanned for my networks that the other networks that usually shows up under bt3 didn't show under bt4. That could hurt the performance depending on your location when running test.
