Cisco Switching/Routing :: VLAN Bridge With Catalyst 3750

I have 3 VLANs here that need to be on the same network segment.  They are going to be used by our Wi-Fi network (with Aironet APs), bound to 3 different SSIDs (as Aironet APs doesnt allow multiple SSID per VLAN), each one with a different authentication method and server.Is there a way to bridge those VLANs together with a Catalyst 3750 switch?  I tryed configuring an IP address on one of the VLAN interfaces, then configuring a bridge with the vlan-bridge protocol (Catalyst 3750 doesnt have the "ieee" bridge protocol type) and put all 3 VLAN interfaces on the same bridge-group, but it didnt work (even with "bridge x route ip").I also tryed configuring IRB bridging, with the 3 VLAN interfaces on the same bridge-group and an IP address on the BVI interface (the way I used to do with old 2600 routers).  Same result.(actually, I didint test to see if the interfaces are actually being "bridged", but I see neither of them can reach the router)
