Not a duplicate of #1380480 as that bug report clearly states that disabling and enabling networking in the applet restores the network. This bug report clearly states that has been tried and does not work.
Note that since 16.04 I've been getting this on all computers that I have and a lot more frequently. A separate bug has been raised for that as it was a different operating system and affects different hardware. See #1589125.
