If theres a client connected I dont even deauth. Just run the aireplay 3 attack untill you capture a packet. your ivs should increase dramaticly. couple of things ive noticed though. 1.kismet and airo dump do not like to work together. 2-leetmode slows down injection for whatever reason. 3-unless you lock airodump the the specific channel it will bogg out after a while and lose all data.
4-try using aircrack-ptw. I can crack my 64 bit key with 20-30,000 ivs instead of 250,000 like with aircrack-ng
