Configuration for md5 not working

Running freeradius 2.1.6 on CentOS 5.3 I have everything configured for md5 authentication so that I do not need to use either server or client-side certificates. I have my access points configured in /etc/raddb/clients.conf and my users configured in /etc/raddb/users My access point is set to WPA Enterprise security using a RADIUS server. When I try to connect to the network, all I get is "Windows is unable to connect to the wireless network" No prompt for username/password or anything. Can someone tell me if its my radius configuration that is bad or my access point or what? Thanks
