Ah nevermind, i'm currently on a 10/100 hub to the gigabit switch. Silly me, you can delete this post, cause I can't apparently?
I'm running an Optiplex 330 with the Broadcom NetXtreme 57xx Gigabit ethernet card. The computer is running Windows 7, 64bit, but there do not appear to be any drivers for that OS.I tried selecting Vista 64bit, but there were no drivers. The Vista 32bit doesn't work. Then I went to Broadcom and found these drivers: [URL] the W764bit drivers didn't change the fact i'm still on a 100Mbit card (as seen on  Local Area Connection Status screen and the Device manager) Anyone a clou on how to fix this?
