Problem with a NIC connecting at 1Gbps
I have an older pc running Windows 2003 and it has a Marvell 88E8001 NIC in it. The NIC is supposed to do gig.
Any time I try to make it go 1gig (say I unplug and plug the cable), the NIC will say (in a ballon above the system tray) "Connected at 1 Gbps", then immediately it will bounce and say "NIC Disabled" and then go back to the connected at 1Gbps message. It will alternate between connected and disabled 3 times before it says "Connected at 100Mbps" and stays stable.
If I go into the config of the card and force it to 1000Mbps FULL, it will continue to bouce back and forth until I set it back to Auto.
I have tried the latest drivers from Marvell's site (dated 9/2010) but to no avail. I have also used my laptop to test the physical port. It connects 1gig no problem.
Is this a setting somewhere or a malfuctioning NIC??? Any help is appreciated. Thanks

If you have access to the port on the switch it is attached to, try setting the port for 1000 full (or half) and the same setting on the NIC - some dissimilar NIC/switches have problems with auto-negotiation.

I do have access but the switch is a small 10/100/1000 8 port Netgear unmanaged. Fortuanately, no of my other 7 ports seem to have any issues.

I just tried 2 other gig switches, two different brands with the same result. This an onboard Nic I can try another pci nic but I was trying not to have to take the server down b
I feel following possible reasons..or ways to troubleshoot.
-> Make sure your are using right version of driver ( win2003 compatible drive)..try different version of drive (older version or latest).
or
-> Try different gig switch. ( it could be switch issue )
or
-> It could be your system NIC issue (hardware issue).

-> I wonder network cable in use...Cat 5e or Cat6 ?.
-> change patch cord or cable in use ...if possible use cat6.
Intention is to try different options before concluding system NIC issue.

You can also try an crosscable instead of normal patchcable...

I installed the right driver (or at least Marvell's site said it was for 2003 server) as well as multiple cables but I havent tried a crossover yet. Not sure if this small switch will auto-sense a crossover though. I have been leaning towards a bad NIC but I though it might just be a setting since the card does work at 100meg.
If you have the time perhaps you try to take another pc/laptop with a working gig lan card and attach this to your NIc of your server..See if the server NIC wants to go to Gb? Try is by using a normal and by a crosscable....If the NIC in the server wont connect at Gb speed then check if all pins in the connector of NIC are OK...
Gb uses all 8 wires of the cable..
When 1 wire is not connecting properly the Gb wil not start and the NIC will donwgrade it self to 100Mb

Great, it was mostly likely NIC problem.
