Hey guys, I've got a problem with my new laptop running ubuntu 11.04. My wireless works flawlessly but my wired connection is not working. In the networking toolbar the wired network button is greyed out. There is nothing wrong with the connection itself, as I have tested it on devices known to work.
Here is a few things that might help...

I found 2 ethernet devices:
Are all your ethernet interfaces listed above?
(If No, modconf will be started so you can load the card
I connect to a linksys router running Tomato firmware before connecting to the net. I gave my laptop a static IP (192.168.1.145).
Sorry, I scanned 2 interfaces, but the Access
Concentrator of your provider did not respond. Please
and modem cables. Another reason for
the scan failure may also be another running pppoe
process which controls the modem.
I looked through the forums trying to find something relevant to REALTEK, but no luck. I have been using linux for quite some time now, but I am very new to networking. I've tried messing with /etc/network/interfaces but it makes no sense to me, so I've reverted it back to normal.
Also are there any good intro to networking guides you can point me at?
