I have an ap model of AIR-AP3802E-B-K9 which cannot join the WLC, I have performed reset on the AP and yet it does not join the controller. It picks an IP address but registering to the WLC is the issue.
I have attached the log from the AP.
Thanks in anticipation!!!
You problem is this:
"Max retransmission count exceeded, going back to DISCOVER mode."
This can be recheability problem. Make sure links is Ok.
