I just installed a new mobo, CPU, CPU cooler. On the old mobo my LAN port (RJ-45) the speed is/was 100mbps. Now on the new mobo the LAN port is a gigabit port. On kids old desktop running XP when you move the mouse over the network connection it will show you the connection speed of 100mbps. In vista it doesn't show this. Is there a way to find this. I am wanting to see the speed difference between the two mobo's.
