Hey I'm having some issues and needed some advice.

I'm running kernel 2.6.27.19 with an intel 4965 AGN wifi card.
I've patched drivers and managed to get the card in monitor mode and I
can inject (aireplay -9 returns good)

In an environment where there exists an associated client to an ap I use

aireplay -3 -b accesspoint -h associatedclient DEV

to start packet injection. Airodump shows that the client is sending huge amounts of
packets but the Data field under the access point doesn't increase and the number of captured ARP packets from the injection doesn't change. I've had it working
on previous occasions so I doubt distance etc is an issue.

modprobe -l iwl* returns

I'm not sure what other details you would need. Thanks in advance.
