I have an old Belkin pre-N router and Virgin internet. I am considering getting a new router and was wondering what people think about the airport extreme versus others, specifically the Netgear N300 dual band routers, such as the WNDR3700? Both are about the same price. I have 3 Macbook Pros and an old Windows xp computer and my mac pro currently on our home network, with my mac pro on the ethernet cable and the rest on wireless. Is the range on the airport extreme good for outdoors as well as going through walls to upstairs? Thanks for any advice.
