Hi

I have been experiencing a really annoying issue for the past 4-5 months where my network will only connect at a maximum of 100 Mbps Full Duplex on a Gigabit connection. It used to run ok at 1Gbps and then for some reason stopped?

System info:

Manufacturer Gigabyte Technology Co., Ltd.
Model GA-K8N Pro-SLI
North Bridge NVIDIA nForce4 Revision A3
South Bridge NVIDIA nForce4 MCP Revision A3
CPU AMD Athlon(tm) 64 X2 Dual Core Processor 4400+
Cpu Socket Socket 939
RAM 4GB PC3200
HDD 4xSATA total 2TB

I believe I am running the correct driver NVIDIA nForce 10/100/1000 Mbps Driver version: 67.8.9.0 Driver date 1/08/2008

I have checked the Configure settings under Local Area Connection Properties and there is no 1000Mbps setting available only Auto Negotiation (which is how it has been set).

This topic has been covered for Vista and I believe here was a fix through some registry editing (happy to edit the registry under guidance, though not an expert by any means).

My guess is that the installation of SP3 may have affected the gigabit lan settings? If anyone has a solution or some regedit instructions that will work for XP pro that would be great.

cheers

What is your connection hooked up to? Router, modem, switch? Is it gigabit?

Hi it is hooked to a gigabit switch - DLink 4 port I have tried a couple of the other ports on the switch one of which is definitely working at 1Gbps for my media pc which is running vista. The switch also has a Lacie NAS HDD connected at 1Gbps and then a Billion 7300G modem / router. All connected with CAT 5e cable. This set up hasn't changed at all and the XP machine was working at 1Gbps until a few months ago.

Thanks for your response

Have you tried a different cable? Sometimes cables can get pinched or bent to the point the wire breaks.

Hi Sturm thanks for the response; yes I have tried a different cable (several in fact) and several different ports on the switch. My best guess at present is that the Nvidia ethernet drivers were written before XP SP3 and in the update now prevents auto negotiation to 'see' the Gbps capability of the NIC. That said if I am correct I have no idea how to resolve that issue :(

I have the same problem with windows XP Home. I have installed a Linksys EG1032 V5 NIC and it did not work any better. I upgraded the NVidia Nforce 4 Network Controller to Ver 5 and it did not work. Interesting part is that NVIDIA nFOrce DID give me 1 GBPS until my ISP went down for 3 days and I use my wireless Linksys EA2500 to inteface with Verizon via cell. BTW my router is Linksys EA4500.
