Vlan Setup issue with Wireless Access Point

I recently purchased 30 SonicPoint NDR access points.

I have plugged in the AP’s directly into the x5 interface of my sonicwall and configured everything including the vLan’s. Everything is working beautifully until I plug in the AP and the interface into my 3com switch. Per Sonicwall support, the ports on the switch need to be trunk ports running 802.1q. This is the case.

The interface sees the AP but the clients are unable to connect.

My switch is a 3com 5500G.

Any help would be appreciated as Sonicwall support is indicating it’s a switching issue.
