I live in a 2 story colonial in Newark NJ with a full basement and a 1/2 attic. Currently, my computer, a P4 2.2G running Windows XP Home, is located in the attic and connected to the internet via Cablevision cable. I will soon have a Core i7 computer running Windows Vista Home Premium, which I will set in the attic. I will also purchase a 4 port wired/wireless router which will be connected to my cable modem in the attic. The XP computer will be moved to the basement and connected to the internet wirelessly. Considering the distance from the attic to the basement, 3 stories down, what recommendations do you have for a router that can give me a consistant and strong signal from the attic to the basement. I would prefer a "N" router over a "G" router, in consideration future development.
