Screenshot of desktop with 'Wired connection" being offered.
Description of problem:
This has happened a couple of times since installing f23, and it seems to affecting the network connecting on virtual machines running in Boxes.
I'll attach a screenshot (or two), but a Wired connection sometimes shows up even though I have no wired connection on the laptop.
It doesn't always appear, but when it does my virtual machine (often) has problems connecting to virbr0. If the wired connection doesn't appear, there's no problems with networking on the vm.

Version-Release number of selected component (if applicable):
$ rpm -qa NetworkManager\*
But this has also been a problem with older versions of NetworkManager.
It doesn't always happen, but it happens on occasions.
Steps to Reproduce:
1. Start fedora
Sometimes NetworkManager thinks there's a wired connection
NetworkManager shouldn't display a wired connection as it doesn't exist.
I've just noticed that the Wired connection just went from Off to On (so presumably it thinks I just plugged in a cable) and it trying to connect.
(And now the wired connection is back off again.)
The two screenshots of Settings were as a started to report this bug (Off) and while I as reporting this bug (On).

Screenshot of Settings > Network > Wired
There's no wired connection on this laptop.

Screenshot of Settings > Network > Wired
Not the wired connection has turned itself On (it was off). This was about 4 minutes after the other screenshot.
It you still experience the problem, please run following commands in a terminal when you see the problem (wired is on):
$ nmcli c
$ nmcli d
and get NetworkManager logs
$ sudo journalctl -b 0 -u NetworkManager
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 23 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
