i'm experiencing a problem with several AIR-AP1252AG-E-K9 converted to LWAPP:
If i run AirMagnet in order to monitor the signal of the AP, i see a signal outage approximately every 20 seconds, but not in regular intervals. At the time of this gap, one ping to a wlan-station gets lost and voice-over-wifi (7921) gets a short outage, too.
I tried another AP1252, same problem.
An AP1242 connected to that WLC (WLC4404-100) has no problems as well as the same AP1252 with IOS.
A change of the WLC Software Version didn't make any difference, neither a change from antenna diversity to right (or left).
Anybody got an idea for the cause of this? Is the AP maybe scanning for other frequencies in that time?
