Gigabit ethernet showing up as 100mbps

I have 2 computers running windows 7 with gigabit ethernet adapters but when I go to Windows task manager on the networking tab, it says the 'link speed' is 100Mbps (rather than 1Gbps).
I am wondering if I should be seeing 1Gbps on this screen even though the router they are connected to is 100Mbps, or if the 'Link Speed' thats reported gets  downgraded to that of the router.

Also,  the 'Link Speed' for a Virtual Machine Windows Home Server that I am running on one of the computers reports 1Gbps.

FYI the drivers have been installed and they all report the proper NIC in the device manager.

The card can only run as fast as what it is connected to, as the router can only run at 100 then the cards will run at that aswell.

I understand that my effective network capacity will run at the speed of the router (or lowest common denominator).
But I want to know if I should be seeing 1Gbps in the task manager anyway.

No, the speed you mean is the Link speed. This adapts to your 100 Mbps router. So this is fine.

you could theck the windows device manager to see if you have a 1 Gbps network card installed.

Any idea why my Virtual machine that is running on the computer is reporting 1Gbps then?

Because it's using a virtual adapter to connect to your machine, not physically to the network.
