Hi, I have two desktops, both running XP SP2, and both have WMP54GS cards inside. They connect to a WRT54GS router. Approximately twice a day, either of the PCs will lose their connection to the Internet. The IP config is still intact and they can see each other on the Wireless Network. I have a laptop with a WPC54GS PCMCIA card. This never loses its connection to the Internet. Does anyone have any pointers as to what's going wrong with the WMP54GS cards? I've been through all the properties to see if there's a "time out" setting. It does appear that the connection to the Internet drops out if the PC has been inactive. Am I looking in the wrong place? Could the problem be with the Router settings? Many thanks for any advice.
