1142N APs cannot join 4404 WLC in the same VLAN!!

can you capture the below through two reboots of the AP:

debug capwap events enable

debug capwap errors enable

no need for capwap packet usually.

Salam Hosam,

Besides what Steve requested, if you can check the console output of the AP when it tries to join that will be also helpful.
What is the software version of your controller?

Do you have the AP manager interface on same VLAN as the management?

Are you utilizing LAG on the controller?

You have all the four ports of the WLC connected to the neighbor switch?

Thanks.

- My controller is 7.0.220.0

- I cannot console to AP becasue they are mounted above ceiling

- management: 192.126.0.100 and ap-manager is 192.168.0.101

- I'm not using LAG becase I have 1 port connect to the switch
