Problem for me at least has not been the MAC layer (either hotel room
or meeting room), it was that the DHCP server was not responding.
Ironically, I could still see everyone's Bonjour and SMB service
advertisements.

if it's wifi that's causing the trouble, the usual causes are:

- insufficient density of APs for the number of clients
- APs configured with TX too high (should be set as low as possible)
- APs configured to accept dot11b <= 9 megs
- APs configured to use auto channel selection
- stupid broken clients screaming at high volume across the room to APs
which are impossibly far away

There is a more fundamental problem, though:  wifi was not designed with
crazyass density in mind.

Bring back UTP?
