Hi, I have a sky wireless router downstairs from my isp and am building a new computer upstairs, parts have been ordered. My os is going to be windows 7 64 bit. my mobo is a asus m4a78-e. I need a wireless card for my upstairs desktop computer to pick up a strong useable and reliable signal from my sky router downstairs for internet access through the ceiling and one wall over a distance of roughly 25m. Any suggestions?
