My main router is a Belkin 300n(F7D7302) connected to my DSL modem at the main house.
The DSL modem is in bridge mode and the Belkin 300n uses PPPoe to connect to the internet.

I have computers feeding off the Belkin both wired and wirelessly.
The DSL modem IP address is 192.168.1.254
The Belkin 300n IP address is 192.168.2.1 with DHCP turned on using the range of (3-100).

In the same house I have a Netgear WNDR3700 which is connected LAN port to LAN port with the Belkin 300n. The IP of the Netgear is 192.168.2.2 with DHCP turned off. I have systems feeding off the NetGear both wired and wirelessly.

Both routers are using the same SSID. One is broadcasting on channel 6 and the other is on channel 11.

Everything in the house seems to be working just fine with both routers.

Now about 400 feet away I have a building where I want to connect to my network at the main house. I have a TP-Link TL-WA5210G which I want to connect to a Trendnet TEW-631BRP. I have a laptop that will connect to the TEW-631BRP with a wired connection. I also have a Sonos music player that will connect to the TEW-631BRP via a wired connection and lastly I have an iPhone that will connect to the TEW-631BRP wirelessly.

My question is how should I set up the TP-Link and the Trendnet router to make sure that all 3 devices in this building will function properly as though they were on the main network at the main house?

Thanks so much in advance for any advice.
