I'm glad you asked this question. We seem to have the same issue though I had not thought of rebooting the APs & controllers to help it. I hate to do this to 3500 Cisco APs and 24 controllers, but I might try it. Hopefully, we will hear from other folks who can shed more light on this subject.

We will get reports of poor wireless quality from users sitting directly under an access point. Often the WCS will report users on the access points with good dBm, but in reality the users can barely search the web. (I cannot remember if the average client SNR was looked at). The "solution" is to reboot the access point. So, we now are now talking about scheduling a reboot of all access points and controllers (4400s) every 3 months. While this may work to keep the problem at bay, it does not address two related questions. 1. Why is this happening? When I mentioned this behavior to a Cisco TAC, they said they had never heard of this before. As this has been our norm through multiple code and access point upgrades, I cannot believe this. 2. What are other schools using to monitor the quality of the wifi? I do not mean the rf interference quailty but instead a way to monitor of how well the access points are passing traffic, signal strength, average client SNR, etc?
