I just updated my RHEL 7 instance to the latest available (I can give a list of all updated packages, if needed) and since restart the NetworkManager 1.2.0-0.1.beta3 claims that there is no connection available, despite me being connected over ethernet cable. The gnome-shell claims I've the Airplane mode on, and that I should turn it off by a hardware switch, but that's nonsense, because the only thing I have the hardware switch for is Wi-Fi and it is turned off. The connection also worked flawlessly before the update, I downloaded all the packages with it. The laptop sits in a docking station, if it matters.
Please provide the logfile of NetworkManager.
Preferably with debug-logging enabled, by configuring it in /etc/NetworkManager/NetworkManager.conf and restarting.
(but for completeness, the logging parts without debug-logging when you experienced the problem the first time, are interesting too).

The NetworkManager log captured by:
$ cat /var/log/messages | grep NetworkManager | grep "Apr 26" >nm.log
Or can you give more specifics about the installed versions (kernel-version, libnl3-version)
You started with rhel-7.2, and upgraded to 7.3 beta? How exactly did you do that, for me to reproduce?
Right, I thought it'll be better to give you my package versions, thus I tried to get the right one meanwhile. It was a challenge, because I was downloading the older version from brew, from a Fedora installation. I ended with this:
$ rpm -qa | egrep -e "NetworkManager|libnm|network-manager" | sort
On the working version, where gnome-shell claims:
- Wired connection (online, I can ping external servers)
- WiFi connection (off by hardware switch)
- Airplane Mode (on by hardware switch - I've no idea where it gets it from)
the packages are:
On the non-working version, where gnome-shell claims only:
- Airplane Mode (on by hardware switch)
the packages are:
These are the only packages I changed to make it work (or break).
*** Bug 1330866 has been marked as a duplicate of this bug. ***
This bug happens, because the NetworkManger package was compiled against a newer kernel (from rhel-7.2), but now runs on an older one.
This was fixed upstream by commit https://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=05e454a98d02e69afd28fe371be48b40c4069a76
When using 1.2.0-0.1.beta3, you also need a rhel-7.3 kernel.
A fixed package is on the way, which doesn't have this issue and would work with 7.2 kernel as well.
I can confirm that this package (together with the same version of network-manager-applet packages) fixed the network issue for me after reboot (re-login wasn't enough, which is expected).
tested with kernel 3.10.0-327.el7.x86_64 and NetworkManager-1.2.0-2.el7.x86_64 w/o any problem
