Continuing from my previous thread, WEP attack after 200 million guesses still has not cracked the WEP key.

So back to Airsnort, given that I need approx 1200-4000 'interesting' packets for airsnort to work, and given that the network I am auditing has very low traffic voulmes, does anyone know of a tool I can use to generate traffic to the access point in an effort to up the level of traffic its generating?
