I'm currently trying to optimize a linux machine which acts as a Layer 3

wireless retries, thus rendering the video on the recieving end
stale/useless.

Maintaining QoS over wireless links, especially in the presence of interference
is tricky, perhaps impossible. My gut feel is that your problems are likely all
wireless-related and the solution will lie there too. Perhaps the radios are
queuing subsequent packets behind the one they attempt to re-transmit ?
Often there are tweakable parameters in the radios that you can try to play
with (enable RTS for example).

Good luck !
