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?
