I have a System76 Kudu Professional version kudp1, it came with ubuntu 13.10 but I upgraded it to 14.04. After the last upgrade I did it stopped detecting ethernet and wifi networks.

nm-tool output:

NetworkManager Tool
State: disconnected

sudo lshw -C network output:

Thanks in advance to anyone that takes a look at this issue I have.

Thanks for your question! Let's grab a couple of pictures to better illustrate what the issue is. Go ahead and open your networks menu in the top-left corner of the screen, then press PrtSc on your keyboard. It's just to the left of the F12 key. That will grab a screenshot that I can use to better diagnose the issue. Make sure you have an Ethernet cable plugged in when you do this. –  Ian Santopietro Sep 23 at 20:53
