Moved your post to the appropriate forum. Do you have a DNS record for your WLC hostname that points to the IP address of the controller? If an nslookup from the client device doesn't resolve the hostname to ip, that would be your issue.
Yes, from a wireless client, post the output from an IPCONFIG /ALL; and also from a wired client that is working properly. It's possible the DNS and WINS entries are different.
It's also possible that wired clients are resolving names from subnet broadcasts, which the wireless clients wouldn't be able to take advantage of. DNS registration (whether manual or done on a Windows AD server) would resolve for both wired and wireless, if they both point to the correct DNS server.
