ethernet

I am new to ubuntu. I recently installed the latest ubuntu for desktop from http://www.ubuntu.com/download. I was very excited to start using ubuntu until I booted the computer and saw that i couldn't connect to the internet at all.

I have spent hours trying to figure this out. I keep running into people suggesting installing drivers etc. I have tried about everything and nothing seems to work.

I have the ethernet cable connected to the computer but it doesn't recognize it. I ran the following:

lspci | grep -i eth

and I get this

09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5752 Gigabit Ethernet PCI Express (rev 02)

Any help would be much appreciated. I am kind of bummed I have spent all this time tyring to get the internet to work and haven't even gotten to use the power of ubuntu

Update copied from comment:

Changing the Ethernet cable to a different one fixed the problem.
