My Realtek NIC in my Windows Home Server (essentially w2k3) box refuses to run at 1000Mb/s even if I change the driver settings from Auto Negotion to 1000Mb/s full duplex. I've installed the latest driver and tried changing the speed setting but I'm having no luck. Not sure what to try next. Any ideas?
I have a Netgear GS605 v2 Switch supports 10/100/1000 D Link DIR 655 router.
All my machines bar one/2 have 1000Mb/s NICs (Old laptop/Xbox being the exceptions)
The reason I noticed the problem was because I was copying files between two machines and maxing one NIC out and only seeing 10% on the other machine. I do have a fairly lengthy cable between the switch and the router (maybe 20m) could that be the issue?
Answer
As others have already noted you need to be connected to a gigabit switch and, of course, there will need to be other gigabit enabled computers connected to that switch to get any practical benefit.
Note that if you are using a garden variety router/modem/switch it is almost certainly going to only be 100Mbit.
The other thing to be wary of is the cables being used. Yesterday I tracked down a similar problem in my own network where one of the computers would only connect at a slow speed. It turned out to be a dodgy Ethernet cable. You will need cables marked as Cat5E or, preferably, Cat6.
