I am trying to troubleshoot why one of our laptops keeps dropping the network connections. The PC is a Quantex TS30T2 running Windows NT 4.0 Workstation SP5. The PCMCIA NIC is a 3Com Megahertz 10/100 Lac cardbus card (3ccfe575bt). I have changed drivers and removed the PC card manager, reformatted and reinstalled all software, but I always encounter the same situation. When the laptop is first booted we are able to browse the network, but as we start to mavoe files or install software over the network, the PC losses all network connectivity. This seems to be independent on what we move/install or size. Any suggestions would be appreciated.
