AP Doesn't See Controller

I have a Cisco 1130 AP and it can't locate the WLC. I have verified the that it's in the correct VLAN. Any suggestions?

Thanks,

Mohamad

Re: AP Doesn't See Controller

Are you using DHCP option 43 to tell the AP how to get to the controller? Or you are doing over the air?

Re: AP Doesn't See Controller

Are your manager and ap-manager interfaces on the same VLAN? Make sure that these two controller interfaces are on the same VLAN as the AP.

Is the AP configured for DHCP? If you ordered the device as lightweight then it defaults to DHCP, but if you upgraded this from IOS then it could be set to either.

One other thing to check is to make sure the AP is indeed running lightweight code. Sometimes Cisco sends the wrong one :) Console in and see if you can run IOS commands ("conf t", etc...).

Re: AP Doesn't See Controller

I have 18 other APs that are just working fine. The VLANs are correct. When I console into the AP, I can't do "config t." When I do "sho run," I see this, which looks suspicious:

power inline negotiation injector x.x.x.x

Any suggestions?

Thanks,

Re: AP Doesn't See Controller

Found the problem. Our DHCP didn't have IP addresses to assign to this AP. I removed some IP from the excluded range and the AP came up.

Thanks for the help.
