Today I replace my FastEthernet switch with a newly bought gigabit switch (DGS-1008A). All computers in my house are displaying that the connection speed is 1 Gbps except for one.

The computer that is not working is an ASUS M2N-MX which contain an onboard gigabit NIC. See ASUS link for confirmation http://www.asus.com/Motherboards/AMD_AM2/M2NMX/

Here are some info of the machine

• OS: Windows 7 Ultimate SP1 64bit
• BIOS version: 1004 (latest)
• Driver: installed via Windows update (latest from Windows update)
• Windows Update: fully updated
• The machine is reformatted 3 days ago, so it's pretty clean, no junk, no virus, etc Cable: Amp CAT5E 5 meters

In device manager, the name of the NIC is "NVIDIA nForce 10/100/1000 Mbps Ethernet"

What I have try:

1. I did try to install the driver provided in ASUS website, but there isn't any for Windows 7 64 or Vista 64.
2. I did try to install the latest nForce340/6100, downloaded from Nvidia website. However, the LAN driver refuse to install, it complain that I already have the best driver installed.
3. I looking in the property --> advance tab --> Speed/duplex settings, in an attempt to force it to run at 1000Mbps, but there is no 1000Mbps choice, only 10 and 100Mpbs.
4. I change the CAT5E cable (use one from another computer that is running gigabit without problem)

Anyone have this issue or know how to solve it?

Thanks
