I built my new computer and the only thing I need now is a wireless adapter. I have a Linksys N router that is located on the first floor of my house and about 50-80 feet away. Since I can not hard wire with an ethernet cable from my room which is on the second floor, I need a wireless card. I want it to be a N wireless adapter. I found two on new egg, but am still unsure about which I should buy. Here are the ones I found http://www.newegg.com/Product/Product.aspx?Item=N82E16833127218&cm_re=802.11n-_-33-127-218-_-Product http://www.newegg.com/Product/Product.aspx?Item=N82E16833315078&cm_re=802.11n-_-33-315-078-_-Product My computer is running Windows 7 Professional 64bit so I want to make sure that whatever N card I buy is compatible.
