I was wondering if anyone has had any luck extending the wifi signal in there house with two airport extremes. I like he idea of two extreme becuase it has the dual band antennas. I have my main time capsule in the basement connected to the modem and was going to put another extreme in the office on the first floor one for wireless printing an two to extend the range of the network. I have a 3 story house(including basement). Any one have any luck with the expansion of the network and any noticable difference?
