Losing Internet connectivity on wireless network

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?

Thanks,
Mark

Is this after an hour of inactivity, or is the connection being used during that hour?
what does the default gateway say after you loose connectivity? how about dns? Does the gateway provide dhcp, or do you have 2 ip's from your isp?

I lose connectivity while using the connection, although if I close IE while I have connectivity, I may not have it when I reopen IE. I am using DHCP. Also I do not have a static ip address, ATT uses DHCP. My default gateway is blank,I believe it was blank before I lost connectivity as well. DNS is set to obtain automatically. Also, I have disabled hibernate/standby feature in power options.
