No ip ipaddress on 450b

We have DHCP enabled for the wan interface but the SM is not getting a IP address. This is the 2nd SM attached to the AP and the 1st is working fine.

I am lost with this one.

we have found that vlans have a tendency to be the issue, or if you use radius that may be the problem as well. if you can log into the radio still see if you can get the config from it and compare to your good one using kdiff3 or something similair

Thanks, that was it. I told the radio to be in vlan 13, but it ignores me and is in vlan 1. But it now has an ip address!
