I have a Linksys G Router and a Linksys G network card. I have the router on my entertainment center. When I sit on the couch across from it (8 feet across and 3 feet lower) I get a connect of Excellent 54mbps, then after 30 seconds to a few minutes, I will lose my iwreless internet connection. Then it will say that a network is available and I have to manually re-connect. When I do I get connected again at an excellent connection, but will keep getting booted and have to repeat the process over and over again.
