My 6 year old extreme is finally giving me problems. I want to change it out for express. I want the faster port an dual band wifi. My question is if I can use my old extreme as just a hub? It would actually work out perfectly if I stash it behind my entertainment center for Xbox and PlayStation use. Where my router is currently located is inconvenient for the things that I actually use plugged in. Can I expect the same range from the express that I get from the extreme?
