Found 2 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to kill (some of) them!
PID Name
723 dhclient3
2137 dhclient3
Process with PID 2137 (dhclient3) is running on interface wlan0

Edit:
you need to have TP-LINK or you can go foe Edmax both are good never go for series coz both are no good to crack WAP/WAP2
