NetworkManager does not always start at boot/first login

Syslog says:
Aug 18 17:03:41 <host> whoopsie[1010]: [17:03:41] Could not get the Network Manager state:
Aug 18 17:03:41 <host> whoopsie[1010]: [17:03:41] GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.NetworkManager was not provided by any .service files

Sometimes rebooting fixes it. Otherwise, need to run sudo systemctl start network-manager manually.

This is a blocker for Internet access (using wlan0)
