To that point- I have had to hit manual override on the fabled RRM algorithm in spots where the APs influence each other to the detriment of the clients. Typically amounts to setting a new min power level that the APs are not allowed to go below, and occasionally going old-school setting fixed power. I find the auto power/channel thing to be good, but not above reproach.

So we can take some time to fix the problem (referring to the room access issue). As Larry mentioned, we used to have many complaints with our hallway 2.4 GHz design, we have almost none with our bedroom 5 GHz design. The cost is different of course! BTW, good luck to have a decent coverage at 5 GHz if you plan to cover from the hallway. The attenuation is atrocious! It is hard to reach the room, and APs "see" each other in the hallway forcing the RADIO algorithm to reduce power. (at least with the kind of buildings that we have at UTK) Best, Season's Greetings, Philippe www.eduroamus.org On Dec 19, 2012, at 10:30 AM, "Jennings, Larry W" <ljenn...@utk.edu> wrote: > David, > During the spring and summer of 2012, the University of Tennessee Knoxville > campus upgraded wireless in the dorms.
