I'm trying to find a way to boost my friend's wireless signal so I can use it across the house. He's using a motorola modem that has wireless built-in. I've heard rumors that these devices generally aren't that great. Would I need to setup a signal booster between myself and the router/modem or should I just buy a wireless card instead of using my laptop's built-in wireless card. I know someone is going to say to just move closer but I'd prefer not to because then I'd have to deal with screaming kids, loud TV, and lack of privacy while gaming or watching movies on my laptop. I don't really have a price range but nothing crazy. Just looking for a simple solution (besides moving closer -.-).
