Wrong IP addresses being assigned to wireless clients

[IT233]

I have an Aironet 1142n (10.30.10.x) that for some unknown reason, is only connecting to the secondary WLC (10.10.10.x). Why is the Aironet handing out 10.10.98.x addresses instead of 10.30.x.x addresses? How do I change this behavior?

I solved this problem by getting the AP to join the primary WLC by: config ap cert-expiry-ignore mic enable

found here: http://server-crew.com/?p=284

Now it is handing out 10.30.98.x addresses as expected.
