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!!!
CAPWAP detected next hop MAC changed from 0007.B400.0E01 to 0007.B400.0E02
Unstable WAN link switching between primary and backup routers maybe, or duplicate IP configured?
Well then why is the AP detecting the next hop MAC address changing?
