Hello,

  Just configured a cisco 2500 wireless controller, I have two wireless AP's and they cannot join to the network as they are giving the following error message

CAP-WAP-3-DHCP-RENEW: could not discover WLC using DHCP IP..Renewing DHCP IP

I Thought I followed all of the instructions but I must be missing something any thoughts??

Is the AP actually getting an IP address?  If so, is the AP on the same subnet at the WLC?

If not you need to configure DHCP option 43 to tell the AP the IP of the WLC.

ok, the AP is now getting an IP. It is broadcasting the SSID However I keep getting a 802.1x timeout or authentication error when trying to connect

Are you using RADIUS to authenticate users, or do you want to use a passphrase?

passphrase. Do I need to configure the IEEE 802.1x in the controller?
