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. ???
