I have a Linksys Wireless G2.4 hGz WRT54G and a Gateway Laptop with a wireless card. When I first hooked up the system it was working and the card on the laptop was receiving an "excellent" signal. But then it suddenly stopped and when I try to detect a signal it is finding something with somebody's name and still not detecting a signal. Any advice would be greatly appreciated. I have moved the laptop to various locations in the house.
