Troubleshooting Wired/Wireless Isolation

I am trying to troubleshoot a networking problem on a small business network. I can't figure out how to turn off isolation of wireless clients.

The network consists of a SonicPoint G TZ210, a Nortel BES1020 48 port switch, and two HP MSM-460 APs which are in standalone mode. The switch is connected to physical port #0 of the SonicPoint. The APs are connected to ports #2 & #3 of the SonicPoint. All ports except #1 are configured in the SonicPoint to interface 0.

Clients that are wired are all able to see all other wired clients on the network & receive internet access with no problems. Clients that are connected via WiFi are able to see all other wireless clients & receive internet access with no problems. Both wired & wireless are on the same subnet and all clients are able to access the SonicPoint's settings page. But wireless clients and wired clients are not able to see each other. I have turned off everywhere I can find AP isolation settings in both the SonicPoint and the APs. I have tried connecting the APs through the switch. I have checked that the firewall is not configured to block any traffic on interface 0. Nothing seems to work. Does anyone have a suggestion what I am missing?
