I've been reading MaxPc for years shortly after it was Boot magazine. Usually pretty good reviews and some real world tests that i appreciate.
Their recent router recommendation was this latest Asus offering: http://www.maximumpc.com/article/%5Bprimary-term%5D/asus_rt-n66u_wi-fi_router_review
I personally own the Netgear 4500 to which this Asus is compared in the article. The Netgear 4500 has been pretty solid. It has a wireless client computer two floors up and at the far end of our house. Downlaod speeds are slightly slower than my wired computer which is to be expected (wired 4-6 mbps, wireless 2 floors up 1-3.5 mbps).
