I am running Ubuntu 16.04 on a laptop
My computer automatically and randomly loses internet connection while still connected to the wifi network (it keeps the display on the top bar, but I haven't confirmed).
Disconnecting and Reconnecting to the wifi network restores internet connection.
Please comment all the info that'd be required to troubleshoot my problem so that people can figure out what's wrong.
Regards, ryzokuken
