hello, recently ive bought a new notebook-acer 5738ZG..it has acer nplify 802.11b/g/draft-n card, shown as atheros AR5B93, i had no problems starting it up..

(im kinda new to this, so im sorry, if ill start using incorrect terms)..so, the problems are:

1) how can i choose a channel for aireplaying? i use airodump -c, but when i start aireplay, the channel is random

2) using aireplay -1 0 i get only ack packets and error that the attack wasnt successful, using -3 argument wont get any arps aswell (is that because incompatibility of my wifi card, incorrect drivers or simple because im a lame?)

thanks a lot for explanation and pardon my english
