I've been delivering a WiFi PoC (focused on video/voice and performance mainly) at a customer in the past two weeks. Version 9.12.04.0003, 3825e APs + dipole antennas. Everything was working perfectly until I activated RADAR (detection only, in-service profile for all APs, scan for security threats and rougue APs and identify sources of interference, no countermeasures enabled). With RADAR enabled (in-service), we started noticing instability in the 5 GHz band, randomly being disconnected from the WiFi infrastructure (or getting limited connection) and needing to reconnect manually again. With Microsoft Lync, upon starting a new video call, after a few seconds, the customer got dropped from the video call and lose connectivity. This happened all the time with Lync, but only in the 5 GHz band. Windows 8 machines. With X-lite, no problems whatsoever but nevertheless, they got random disconnections/limited connection from the WiFi infrastructure (I experienced that also with my Windows 7 machine), with the need to reconnect manually again.
Upon disabling RADAR, everything started working perfectly again...
Does anyone know of issues with our RADAR (detection only, in-service profile) with the 5 GHz band? I'm using non-DFS, 20 MHz channels.
Thanks in advance.
