Public bug reported:
Internet drops every few minutes on both wired and wireless connections
even though connection icon indicates the computer is still connected.
Dropped internet is discovered with "The site can't be reached" screens
in Chromium, or error messages when downloading/updating in Terminal, or
missing connection in Application Manager, or stalled syncing in Insync
application (occurs even with Insync paused).
Disconnecting and reconnecting via the connection icon resets internet
temporarily.
Internet drops more frequently on wireless than on wired.
It seems to disconnect more frequently with heavier internet use (e.g.,
downloading multiple files, opening several webpages in quick
succession).
This is a fresh install (yesterday) of Ubuntu 16.04 on a Dell Inspiron
15 5567 (dual boot).
Ethernet and WiFi both work in Windows 10, so it is not a hardware or
router issue.
