Using two wireless routers on the same network

I have two wireless routers as well as a switch. Here is how my network is setup

Internet->Dlink DI-634M->wirelesss->computer acting as bridge->switch->more computers

Works fine although the DHCP doesn't make it through the computer acting as a bridge so I set them as static
Router set to 192.168.1.1
Everything Else 192.168.1.100-192.168.1.254

Internet->Dlink DI-634M->wirelesss->computer acting as bridge->switch->Dlink DI-624->wireless

I have the DI-624 set up as static 192.168.1.2 with the same SSID and wpa encryption. It works fine until I turn on the wireless radio on the DI-624 then the wireless goes down. I tried setting them to separate channels so they don't interfere but they always do. Any ideas. I realize this is a little bit of a weird setup but if I can get by without buying a repeater it would be cool.
