I am also having the same issue on my Thinkpad E460 under Ubuntu 17.10.
It started a couple of week ago and got really annoying. Sometimes the
connection is just gone for a few seconds up to 2 or 3 minutes and
sometimes it seems turning the WiFi module off and on again helps. The
same problem occurs via Ethernet too, but less frequently.

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.
