Ok, I installed a Linksys Wireless G PCI card into one of my computers about.... 20-30 ft away from the wireless G router. It worked until I switched cases and had to install a new HD. Now it seems the card won't keep a consistant connection with the router. It will disconnect or lose connection at least 3 times an hour, while the computer is in use. Any suggestions as to why this might be happening and how to fix it?
