My connection is wired, the computer is connected directly to an Alcatel 
SpeedTouch router. There is nothing wrong with the router because other 
computers on the network connect to the router wirelessly with no 
problems at all.

Here is an output of sudo dhclient eth0:

ibs at ubuntu:~$ sudo dhclient eth0

It seems to me that dhcp isn't working.
I have already tried to set a static IP which used to work for me in 
Ubuntu Warty. I used the gnome networking tool and set the IP to 
192.168.1.10, subnet mask: 255.255.255.0 and gateway address: 
192.168.1.254 
But that did not work in Hoary.
