I am using a Acer Aspire One. Here is the Ubuntu Wiki Page about my computer.

I have a working wireless connection however when I plug a cat5 (Ethernet) cable in the lights flicker on the computer, but then nothing happens.

Output of iconfig:

Any understanding of this output is greatly appreciated.
