so i just bought this stuff off ebay so i can use my laptop in any room for the internet. I have cable internet btw. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5838148399&rd=1&sspagename=STRK:MEWN:IT&rd=1 Well, i read reviews AFTER i bid and payed for it and im not hearing anything good. I have a compaq presario 2100 laptop. Will i have any problems with this stuff or should i just re sell it quick and get something else? Any suggestions?
