Do you know what ethernet name is being used?  Since your WiFi is a USB 
dongle, there are a lot of possiblities.  All the more reason for 
journalctl.

If you know the MAC address you can create:

/etc/udev/rules.d/70-persistent-net.rules

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", 
ATTR{address}=="02:c3:04:01:77:c3", ATTR{type}=="1", KERNEL=="eth*", 
NAME="wlan0"

This will 'fix' the name you need for ifcfg-wlan0

No /var/log/messages anymore.  It is all journalctl.  Look in that 
directory.

Would not know about lxdm.conf
