WLC 2100 cannot locate AP1242AG

The AP1242AG is a LAP, it has red light flashing, my controller cannot locate the AP at all.

AP1242AG:

Cisco IOS Software, C1240 Software (C1240-RCVK9W8-M), Version 12.3(11)JX1, RELEASE SOFTWARE (fc1)

I cannot config a thing within the AP console because it is a light weight AP... Controller cannot detect this AP and hence there's no way to configure this AP at all... Help. Thanks.

Hi,

Please take a look into this example guides.

They contain step by step guidance and troubleshooting examples and i am sure you will succeed with them.

Re: WLC 2100 cannot locate AP1242AG

The APs need to either be in the same subnet as the WLC or to get the controller ip address through option 43. It's not up to the controller to detect the AP.

If you plug the AP directly to the WLC, maybe try to have the AP connected to a switch and get an ip address.

To plug the ap directly to WLC you need a correct DHCP pool configured on WLC.

I'd suggest reading the first pages of the WLC config guide.
