Troubleshoot FAP 221B not visible in controller

[gojj]

I' ve installed FAP 221B with FortiWifi 60D and used it as Controller at some 3+ sites. Just added the APs to the network and let DHCP assign a IP and it was found and I could authorize it. I' m on a new site and the AP gets IP and its possible to communicate with it but its not visible in the Controller for the authorization process. What is the more common issues on Controller/AP and how to best troubleshoot this? Any ideas are appreciated.

What' s the network topology at this new site? Firmware on both AP and FGT? New AP?

Hi, almost immediate after posting this message I found one thing thats different between the FortiWifi 60D. On the previous ones there is FortiOS 5.0.4 - but on this one, with the issue, we only run FortiOS 5.0.3 We use an ip plan of e.g 172.16.0.0/22 Where FortiWifi is 172.16.0.1 and all APs starts with 172.16.0.24x and clients connection to them are located in e.g 172.16.3.0/26 (tunnel mode) AP:s are initially FAP OS 5.0 build 032. They are all new AP:s. I will upgrade the FortiWifi and see if that helps. Should have done my homework more throughly....

Configure option 138 on the DHCP server to provide the IP address of the controller. This info is listed in the wireless deployment guides. For 4.0 MR3 see page 45. For 5.0 see page 40. If using Windows server, see this KB#FD33978.

5.0.3 vs 5.0.4 should not matter... Telnet to the AP to see what the output of " cfg -s" is.

They seem to be more of the default values.

[Bromont_FTNT]

Yes, those are the default values on the AP... the IP addresses you see there are only used if it doesn' t get an IP via DHCP, the AC_IPADDR is only used if it can' t discover the controller via other means. The Fortiwifi is on 172.16.0.1/22 but the AP is on 172.23.36.241?

[gojj]

AP is 172.16.0.241 in this example - the other IP was a misspelling in this case with example IP:s

Upgraded FortiWifi 60D to Forti OS 5.0.4 and no luck with that either.

I updated the FAP to the newest firmware build 048, but no luck. Found the webpage and that states: AC Discovery Status Discovering AC ... Seems it cant find the Controller for some reason. But it possible to ping 172.16.0.1 from the FAP itself so it should be able to discover the Controller which should be 172.16.0.1 I presume.
