My Netgear router says, I can use 'any wall outlet as a wi-fi hub to boost my wirless signal and eliminate dead spots'. Now assuming I'm reading this correct, it says I can use more than one router to get better coverage in my home? My house is three floors, and as far as I'm concerned my main floor is most important since my desktop is down there. My wife does not share this feeling with me. The performance isn't too bad up on the third floor but it is intermittent so the only thing left I feel I can try is signal strength. I have a Netgear N600 WNDR3400 and a N300 WNR2000. The guy at best buy said I can use my 2000 upstairs with the 3400 downstairs. He didn't say how. Anyone know about this? Also what do I need so I can atleast try the 5ghz channels on the 3400? Can I buy a USB wireless adapter for my laptop? If so can you recommend one I don't know what I'm looking for. I'm sure none of my computers support other than 2.4ghz.
