I have Ubuntu 12.04 LTS and for some reason, Ubuntu will not use an Ethernet cord. It will recognize it and say that I have a connection, but it won't access the internet through it. I plan to use Ethernet to upgrade, as it is a more steady connection with better speeds than my Wireless, and it worked before...Why won't it work now?

The WiFi works great, stays connected better than Windows, but when I plug in the Ethernet, kaput. No more internet. It won't connect again unless I unplug the Ethernet cord. ???

Try to remove your Wired connection and remake it. I think you might have some problems with your route.

How would I do that? Sorry, I'm rather new to Linux system administration – RPi Awesomeness Mar 1 '13 at 12:57
From top panel, network menu > Edit connections > Wired; Select your current connection and remove it. Then add another one. – Mostafa Shahverdy Mar 1 '13 at 12:59
Well, that appears to have done something... I erased the profile for the Ethernet, then I plugged it in again. The usual problem came up (with both going, no internet) so I disabled the Wireless via the hardware switch and set the Ethernet to Auto Ethernet. Only thing is, I have to continually click on the Auto Ethernet option to get it to stay... – RPi Awesomeness Mar 1 '13 at 13:04
Wierd...Unity does a WAY better job of getting good speeds out of the Ethernet than GNOME Classic ??? Anyways, thanks! That seems to have fixed it! – RPi Awesomeness Mar 1 '13 at 13:09
I think unity has become stable enough to make it your default desktop manager ;) But there is no difference between Unity network manager and Gnome classic's. – Mostafa Shahverdy Mar 1 '13 at 13:12
