I'm using aireplay to collect some data from AP alongside with aircrack. Unfortunetlly, the proccess seems quite slow to me as I've reached 2000 in more than 20mins so far. What most affects the speed of data collecting? PWR of AP is -77dB. Thanks.
you should use airodump-ng to get the traffic. not aireplay. But that asside you can replay traffic you capture with aireplay as stated here
if there are no clients available you could use aireplay-ng to fake auth and then replay the traffic as stated here
good luck and stay safe
