Friends--
Cannot connect reliably to ethernet nor at all to Internet:
Symptoms:
About 2 weeks ago did an upgrade. Have not been able to connect to ethernet nor Internet. Today, for example, boot up this System76 laptop and there was no network connection. Did sudo mount -a and got some internal network connectivity:

Things I have tried:
sudo start network-manager: no help gksudo gedit /etc/network/interfaces changed line to iface eth0 inet dhcp: no help gksudo gedit /etc/NetworkManager/NetworkManager.conf, I changed managed=false to managed=true. Then sudo service network-manager restart: no help: network is unreachable sudo pkill -9 NetworkManager: no help gksudo gedit /etc/resolve.conf added line nameseriver 8.8.8.8: no help
I know very little about networking; to date this has simply worked.
Thanks for your help!
