Wireless AP WPA2 with Radius on SBS 2003

[MVD100]

Hello,
I am trying to configure my SBS 2003 SP2 to use a Linksys/Cisco WAP200 wireless access point. The WAP200 is configured for Radius and I believe everything to be working on this device. I have tested it with SSID broadcasting in WEP configuration and it works fine. However, when using WPA with Radius configuration I can not connect. I have used this Microsoft Document to set up the SBS 2003:

I am wondering if it is a certificate issue? Any thoughts? Also, the WAP200 is not logging any errors.

Update - I'm getting closer but still have some issues. I enabled the VLAN setting on the WAP200. I enabled the log feature. I now get the following feedback from the WAP200:
Jun 12 12:43:39 WAPSSID daemon.notice httpd[68]: [Httpd]: Authorized Login from 192.168.1.115 (that's my laptop).
I still cannot connect. So, I added the VLAN ID of 1 to the WAP200 and checked the box to enable WMM (WiFi-Mutimedia, not sure if this matters). Now I get the following from the WAP200 regarding the SBS 2003 server:
Jun 12 13:17:03 WAPSSID daemon.notice httpd[68]: [Httpd]: Authorized Login from 192.168.1.1
So they seem to be communicating. However the server event log shows Event ID 18 that indicates the shared secrets do not match. They do, I double checked them. So why can't I connect? Anyone have an idea? Thanks.
