AP's are unable to join WLC 4402

Hi All,

I am trying to setup WLC 4402 and AP's AIR-LAP1131AG-E-K9 in our production enviornment but unfortuantely facing few issues.

Network dhcp server is configured with option 043 to facilitate AP's and Wireless devices to get an IP from dhcp server, I can see the AP's receievd IP's from dhcp server but still I can't see them on WLC. I have checked that on AP's and it looks like to me that the joining process was keep reseting and access points re-initiating the process, I have checked no other devices on the network have same IP and there's no IP conflict. Then I cofigured AP manually and assigned IP, Controller IP and Default gateway but still no Luck.

Please find attached network diagram and error files, AP's can ping all other network devices and all other devices can ping AP's.
The issue is AP's are unable to join WLC.

So you've sorted that out now then?

Well there wasn't any device on the network with same IP but anyway just for the safe side I have assigned static IP to the AP that's not even part of dhcp pool.

Can you install v6.0.196.0 on the WLC and try again?

Hi Craig,

Please find attached log file of AP after WLC downgraded to version 6 from version 7, this AP is on manually assigned IP that is 192.168.10.160. I can ping gateway and all other devices from this AP and this AP from other devices, I can confirm you that there's no other device available on the network with similar IP address.

Ok, on the WLC at the CLI can you please do:

debug capwap events enable

Open in new window


...then power the AP and let it attempt to join the WLC.  Post the output from the WLC.

Hi Craig,

Please find attached WLC Sysinfo output, the boot loader is still of version 7 as we don't have one.

There's your problem...

Configured Country............................... US  - United States
The AP Model is: AIR-LAP1131AG-E-K9

The WLC is using the US regoin, but the APs are from the Europe region.  This means the WLC will deny the connection from the AP.  To allow the WLC to accept the connection from the AP you need to change the country code, or add another one...

On the WLC in the CLI can you try this:

config 802.11a disable network
config 802.11b disable network
config country US,GB

Open in new window


Press Y to accept the change, then do this...

config 802.11a enable network
config 802.11b enable network

Open in new window
