Wired

I am not able to establish a wired network connection between two computers on which I just installed Ubuntu 10.04.

I am new to this environment. Unlike in the Windows environment, where it happens by just connecting them with a cable, Ubuntu keeps flashing a notification saying "Wired network disconnected". Am I missing a driver or something?

I am able to connect to the wi-fi router without issue. The wired connection is just not working.
