I've got 4 AP's out of 7 that didn't join the controller. They get an IP address and should use option 43 to join as the other ones. show cdp neighbors learned me that they run a recovery image (AP3G2-RCVK9W8-M) but I am unable to log in using Cisco/Cisco. RTFM didn't help me, how to fix this?

Problem solved, it seems that the configuration of the DHCP scope between two Windows DHCP servers wasn't properly synchronized. The failover server didn't had the router option, so the AP's in the second half of the scope didn't get to the controller. One of the disadvantages of function separation.

The time is NTP Synced. I triple checked al DHCP scope settings, routing. What puzzles me is I can ping the 3 Ap's that have joined the controller but the 4 that didn't join I can only ping from their default gateway though they are in the same subnet as the other 3. Problem is they are 100 miles from my current location and the controller is in a remote datacenter.
