Query: Disappointed with N1

I upgraded to N1 for our house because it is adobe (earth brick) and have had trouble with attenuation on my previous router. N1 works no better - about 20 feet thru 2 walls knocks it out. I bought a Buffalo AirStation (WLI-TX4-G54HP) and it works much better - even though it's not N1!
