Annoying Internet Connection Problem

[Mar46396]

I have been experiencing intermittent network problems for a long time now, and i'm ready to use the sledgehammer.

My system--
Tyan Trinity 510 w/VIA P4X266 Chipset
Intel Pentium 4 1.8
ATI Radeon 8500DV Video
Sound Blaster Live 5.1 Platinum
Netgear FA311 NIC
256MB DDR SDRAM
Windows XP Professional

I can surf the internet for awhile, and the connection will drop. The time it takes to drop is completely random. To get connected again, I have to disable my network connection in the control panel and re-enable it. All the lights on the cable modem are on, and I have had a service tech over to measure the level and everything checks OK from the cable company side. It still has an IP address in ipconfig, and all the lights on the network adapter are still on. I have tried 3 different NICs, all with the same problem. I suspect a software/motherboard problem. I just freshly re-installed Windows XP. My cable connection uses DHCP, and no computer name is required. I tried different PCI slots as well.

Thanks
Marc

Have you upgraded the firmware of your cable modem? Tried with a completely different computer?

Haven't upgraded the firmware, from what I understand that is the cable company's job.

I will try another computer later today and post results here. Thanks
