AP will lose association with controller and then reassociate.

I have 240 AP's on a 5508 controller. The AP's are at 12 different locations and they all stay associated except for one location. This location has 2 AP's and when they lose the association with the controller it is always both AP's at the same time. I have nothing in the logs on the switch they are connected to, the ports on the switch are not dropping. My link to the building shows it is stable, but I still have this problem. They associate with the controller after about 15 seconds.

Hi,

 

*Nov  6 15:32:26.611: %CAPWAP-3-ERRORLOG: Retransmission count for packet exceeded max(CAPWAP_WTP_EVENT_REQUEST

Looks like it is loosing the heartbeat with the WLC.Just try to increase that value if that helps.

Is proper QOS in place to prioritize Capwap packets.

What firmware is your controller running on?

Ok, try upgrading your firmware to 7.6.130.X and see if this issue re-occurs.

Exactly Mr.Leo.

I faced the same issue and after upgrading it to 7.6.130.0. It worked for me.
