TP-Link 300Mbps Wireless :: Using WR940N As Bridge?

Region : UnitedStates
Model : TL-WR940N
Hardware Version : Not Clear
Firmware Version : latest
ISP : Time-Warner

Just purchased the WR940N to use as a wireless bridge. I expected to be able to have the router join my wireless network, and provide Ethernet connectivity to 4 devices behind it. But I'm missing something in the configuration. I can get it on the wireless network, and manage it via the wireless network. But devices plugged into the Ethernet cannot get out to the Internet. Basically, I have a 192.168.1.x network, and the router is node 192.168.1.3 on the wireless network. I've turned off the firewall and DHCP on the router. The Ethernet devices behind it get an address from my network, but the router inserts its own address in as the default gateway, and my Ethernet devices do not have a route to my 192.168.1.x network, despite having an address on it.
