Bridged Router

So I ran out and bought a set of power line adapters, and they worked, but I just didn't see the performance difference that I was hoping for. I could make a connection with the adapters, but it wasn't a stable connection, and I saw better connectivity with a 3 year old wireless-g bridge.

So it occurred to me that I have this new router with the N setup on-line but not being utilized. What if I got another wireless-N router and set it up in bridge mode--would I see better connectivity and throughput? Has anyone tried this? Any thoughts on this setup?

Thanks in advance!
