AP-1121G do not even try to join to WLC-1206

Question

Hello!
I upgraded 1121 to lightweight with upgrade tool.
Now I want it to be joined to 2106.
In debug packet I see that 1121 sends discovery request (broadcast, or, after I addedd dns record unicast) to 2106 and 2106 replies.
Then there is no join request from AP.
2106 is in master mode.
What can be wrong?

Answer 1

>If you physically console into the AP (is that available on an 1121?) and I think password is like "Cisco" on most APs, you should be able to see the log.
unfortunately, there is no serial console on 1121 :-(
>Is the controller and AP in the same VLAN/Subnet? Same switch? Is it the same VLAN/Subnet as other working devices?
They are in the same subnet, and I tried to connect them using one switch.
>Could you post the run-config of your WLC?
