I have 2 laptops at home both using the wireless network I setup using a Linksys router. My Toshiba laptop works perfect. My HP laptop loses the internet connection for a couple seconds every now and then. If I am watching streamin video, the Toshiba is interrupted while the HP keeps losing the signal and buffering. This has to be the wireless card right? Can I buy another wireless card and replace it or does that need to be done by people that know what the fuck they are doing?
