Hello

I have a very similar problem with 1142 Access Points connecting back to a central FlexConnect Controller.

The WLC is running version 7.6.100.0

We see the same errors in our logs and debugs on the access points.

We notice that the controller association time is always resetting so the AP only joins for a matter of minutes.

Did you every find a resolution to this problem?

Thank you

Greg

Hi,

In fact what we found was a network connection issue that was causing the problem, check the firewalls and also the WAN metrics.
