Our AP placement design was based only on 5Ghz coverage using power level 2 (1/2 power). 2.4 travels a lot farther so some of our B/G radios are tuned so far down that they are effectively off.

I've found changing transmit power has very little effect within a single "open-plan" room, it only really seems to have much effect when the signal hits obstacles such as walls, and shelves of books etc. Many Thanks Peter Peter Methven.

I've just gotten a request from a group that wants to run 50+ clients in one room. The last time we tried that about 4 years ago, it was a disaster. We had fat AP's at the time. There were a lot of Mac's, and they kept grabbing each other instead of the AP's. Ugh. How do folks handle this now? With my current system can I just throw a couple more AP's in the room and let them have at it?
