Ok this is the low down. I AM using the actual MAC to my card that is broadcasting. I run:

aireplay-ng -5 -e ap -h my mac ath0.

The program runs i get a packet in i press y then it says.

No answer. repeating...
trying a LLC NULL packet...
No answer. repeating....

Still nothing. Trying another packet...

I have used over a 100 different packets all same answer. I have tried this on 4 different router configurations still nothing. I know my cards are in monitor mode. I am aslo using a Ubiquity 300mw card. I have success collecting an arp and deauth attack as well with fakeauth but i am just trying to get the Frag attack to work. I have also followed muts' video from offensive security line for line and still same result. Anyone can give any insight to this?
