Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

Ok, I'm having a bit of trouble getting this setup. I'm not really sure what direction I need to be looking in.

I am on ATT UVerse and I have to use their horrible 2Wire Modem/Router. But with this router, I have very limited control over my network and my wifi range is too small for my house. But, I have a hardwire ran to my TV which I have hooked into a switch and split the line to my PS3. The problem I'm having, is I don't know how to get the Buffalo DD-WRT setup as a subnetwork so that the PS3 can find my Media Server.

Here is a diagram of what I'm trying to accomplish:

Blue is ethernet.

Since you have to route all traffic on the existing 2-wire router because it owns your Internet connection, there's no benefit to having the DD-WRT machine route too. It can only hurt you. So you'll want to use the other router purely as a switch and an access point.

Since you only have one LAN, you only want one DHCP server. Disable the DHCP server in the DD-WRT machine. Also, turn off WAN and bridge the WAN port to the LAN, otherwise you waste one Ethernet port. (Or just leave the Internet/WAN port unconnected on the DD-WRT router.)

I hate doing it this way, but you were right about it hurting me. At least now I can stream HD to my PS3. :) Thanks much. –  MadBurn Dec 11 '12 at 3:49
I agree that it kind of sucks that you have no choice but to use their device as a router. But once you've paid that cost, anything else you try to do just makes it worse. –  David Schwartz Dec 11 '12 at 5:04
