I am using (2) 5508s running version 7.0.240.0. Occassionally the WLAN temporarily disappears, the clients drop, and the WLAN re-appears. The majority of the clients are iMacs. The WLAN is open with no authentication, the SSID is being broadcasted. The APs connected to the WLC are 1142s and 1262s. I have tried to turn off AutoRF, and hard set the AP power level, but it did not solve the problem.
Is this a known problem?
