Thanks for the reply.. but I did figure out what I was trying to do. Basically, I needed to create a bridge and also extend the wireless network. I have modem/router1 upstairs broadcasting there. My WDTV I wanted to connect was downstairs and a wired solution was not an option. The wireless signal downstairs was also pretty weak so repeating that signal was also something I wanted to accomplish. I wanted to maintain a single network.
I used router2 as a bridge and hooked up router3 to it using a wired cat5 connection. Bypassed all DHCP on router 2/3 and it seemed to work. I forgot to enable security on the second router and couldn't figure out its IP address so after getting things to work, I reset both router2/3 to configure a little better (static IPs, Security, etc.)
I enabled bridge mode on router two again, but decided to to allow it to broadcast a wireless SSID- I then found a setting that would allow it to run as a client and access point simultaneously. I know this hurts performance a bit, but I'm really only accessing the internet and some very minor file management and streaming. It works and its plenty fast. Router 2 was 15 bucks from monoprice and I'm happy.... and more importantly, sane. Amazing how much I learned today that I'll have forgotten tomorrow.
