I currently have a DGL 4500 in router in my basement and 2 pcs hooked up to it and a NAS, and a xbox in the living room. I plan on building a htpc for the new 50" plasma i just got but I still want to be able to have my xbox hooked up to the net. Can I just get a router, assign a different range of IP address so it doesn't interfere with my current router and thus split that one ethernet connection into 4 (or however many ethernet jacks there are on the router) without a significant loss in performance? I don't want it to be laggy as I'm streaming from my nas.
