I have a main family computer on the first floor of my house. I just got a computer for the second story which I will use mainly for poker. I already have a wireless conection set up for my laptop, but it is unreliable, sometimes being full strength, other times not being able to connect at all. I went as far as buying a range expander which makes the signal stronger when I can get a connection, but I still can't always get one. What is the best way to get a reliable internet connection? I don't think getting a 70ft phoneline cord would help if I were to hook it up to my modem. Thanks
