I am building a two story house (w pool area outback) that has CAT5 infrastructure throughout. I currently have an AirPort Extreme N base station. I want to know the plusses and minuses of: 1. Using a SINGLE AirPort Extreme N base station, and augmenting range with numerous AirPort Express. OR 2. Using MULTIPLE AirPort Extreme N base stations It's obviously more costly to do #2. But do I loose any range or bandwidth going with #1?
