Gigabit issue with Vista??

Hi all,

I've been in the process of upgrading to a gigabit setup, I didn't have any cat5e cables so I ended up getting cat6.

Replaced the cat5 with the cat6 in my 3+ year old box running Ubuntu and everything works perfectly, switch and box both say I'm connected at gigabit no problems.

Replaced the cat5 with the cat6 in my new machine running 64bit Vista...no go. It wouldn't recognize the network, then after disabling and enabling the network adapter, it went through a loop about 5 times saying the network cable is not connected, then trying to identify, then back to network cable not connected.

After running through this loop about 5 times, 30 seconds later it finds the network and everything SEEMS okay, but the connection is only 100Mbit. The switch and the OS both say so.

Here is my setup: the switch I'm connected to is a Netgear GS608 8 port gigabit ethernet switch (with a Trendnet TEW-633GR on the backend) and the network adapter is an integrated Realtek RTL8168B/8111B Family PCI-E Gigabit Ethernet in a Gigabyte EP34-DS4 mobo. I've tried a few different cat6 cables and the above outcome is the same, can't find the network for 30 seconds in the loop, then a 100Mbit connection.

I went on windows update to see if there was a driver update for the network adapter, indeed there was, so I installed it and still no dice.

Unfortunately I have no other OS installed on this machine to try the gigabit with.

Does anyone have an idea of what is going on here or how to fix it?

Thanks in advance!
 
No, they are bought from a reputable distributor, snagless Cat6. I'm using the same sort of cable for my Ubuntu box with no problems...
 
The drivers on the Realtek's site are the same as the ones I already had. I reinstalled them with no dice. I also installed the diagnostic utility. There were some tests to run on the card which all passed, and it did some checks on the cable which all came out normal.
 
The GS60x switches have cosmetics which sometimes interfere with large cable connectors -- the solution is either to push in the cable hard or better yet, to get different cables with smaller connectors. Not sure what you have; just throwing this out.
 
I saw the same thing at my school, Would even do it with the computer off (looking at link lights). pluged the same cable into the same identical computer next to mine, worked fine. Onboard ethernet was failing. Might be the problem here.
 
Make sure your NIC is set for Gig / Auto in the NIC properties.

Sounds like a physical problem, but I don't trust diagnostics with these onboard chipsets.
