You could do a screen capture of your VSC/SSID interface and attach it here so that we can see the settings you have.
There are also 2 ports on the MAP 320, and it would be good to understand which port is currently connected to the network.
From there, I should be able to understand a bit better what's going on. If I don't then I will most likely as you to provide a syslog capturing the process of a new user coming in and trying to access the network.
