Ok, I'm new to this, so bare with me.
I currently have a Cisco E900 setup as my AP at my ISP connection, I have setup my Tenda W308R as a wireless bridge to provide stronger wireless signal upstairs as well as to provide my XBOX with a wired connection. This has worked in the past, unfortunatley I did not write down what I did to get me there.
I can access the internet wirelessly via the tenda, I can access the internet via the Cisco wirelessly and wired. I Cannot access the internet wired to the tenda.
I have the Tenda in Bridge Mode, I have the security setup correctly, DHCP server is off on the Tenda and the Cisco's is on and assigning IP's over the bridge.
