Uhm, dumb question. If it is that important, why are you using
wireless at all? Why not install a cheap switch/hub in the middle of the
conference table and let people plug a patch cord from the hub to their
laptops?
Stupid pen-test tricks, instead of using an expensive WiFi scanner and
cracking WEP; often you can collect better intelligence with a radio
turned to the frequency used by wireless lapel mics used by executives
during briefings.
