sudo lsb_release -a; uname -a; echo; sudo lshw -C network

Thanks

  Are you using DHCP or Static ip? Your laptop is wireless If you have static ip simply put in your ip info

I'm using DHCP.

If you run:

sudo modprobe e1000

Then connect the wired connection. Is it ok?

Pardon me guys, but the last input reminded me that I blacklisted the Ethernet driver due to CPU-fluctuations. I removed the blacklisting and I my network connection is back.
