this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1666432 Title: Internet drops every few minutes on wired and wireless connection Status in network-manager package in Ubuntu: Confirmed Bug description: Internet drops every 1-30 minutes when connected via wired or wireless (i.e., this is a problem on both wired and wireless) even though connection icon indicates the computer is still connected. Disconnecting and reconnecting via the connection icon resets internet temporarily until the next time. 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 Ubuntu Software app, or stalled syncing in Insync application (occurred even without Insync). 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). It occurs when running Live CD as well though. Ethernet and wifi both work without randomly disconnecting in Windows 10 on the same machine, and ethernet and wifi work on other machines running Ubuntu and Windows with the same router, so it is not a hardware or router issue.
