[Ubuntu 12.04] Wired connection

**enezx** · May 2nd, 2013

I have Dell Inspiron 5420 and I cannot connect to ethernet. I am able to use wireless though.

Strange thing is that a while ago nothing - (wired and wireless) worked. So I had to install drivers for that. Then my LAN worked and after I made my wireless working, LAN stopped working. Why is that?

Help
