What is the device the other end of your enet cable is connected to, a modem or a router? The NIC in that device also has to support a 1Gb connection as well otherwise you get the results you did when you tried to force it to sync at 1Gb.
What OS is your PC running?
I am running XP Home SP2.
I am plugged into my 600 Netgear router plug in 4 and then a UBEE modem plugged into LAN 1 with the wireless turned off onthe Modem.
