..but the AP cannot get to the RADIUS server.  okay, several choices.

1) AP misconfigured...you didnt put correct IP address into the AP
2) RADIUS server is somehow isolated from the AP on the network level -
you say you dont have a firewall running on the server - if I take
that at face value, then theres a block elsewhere....ACLs on router VLANs?
3) AP network is misconfigured - incorrect subnet mask, gateway etc

so....take the AP offline, give a Linux box the same IP details and see if
it can 1) ping the RADIUS server, 2) use netcat to through some junk to port
1812 UDP to the RADIUS server
