Bug Description
I have a Dell Precision 5520 that came pre-installed with Ubuntu 16.04.
I use it at home on wireless exclusively. When I take it to work, I plug it into ethernet via the ethernet dongle. Without fail, almost an hour later, all networking stops working. I can ping neither domains not IPs, even on my local network. If I try to run `sudo service networking restart` or `sudo service network-manager restart` then Gnome-Shell hangs.
If I switch to an Fn terminal, I can run some commands, but eventually all sudo commands there hang too. Holding down ctrl+alt+del says "ctrl+alt+del pressed 7 times in 2 seconds, rebooting immediately", but after 15 minutes, it still doesn't reboot, forcing me to do a hard reboot.
Afterwards, the laptop works fine until the next day, when it all happens again.
