I have set up a home network w/2 computers running WinXP Pro, 1 P2 400 desktop, and 1 Dell LatitudeP2 366. I have a cable modem internet connection connected to a 3COM Home Connect wireless gateway. The desktop has no problems, however the laptop, using a Xircom 1120 Wireless pc card, sporadically loses internet connectivity, but is still on the network and can connect to the other computer. I can sometimes get it back by rebooting the cable modem or the gateway, but it loses connectivity after an hour or so. I have reinstalled IE 6.0.2, but that didn't help. Has anyone out there heard of anything like this?
