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

Add line:

SUBSYSTEM=="net", ACTION="" DRIVERS=="?*",

ATTR{address}=="[MAC_ADDRESS]", ATTR{dev_id}=="0x0", ATTR{type}=="1",

KERNEL=="wl*", NAME="wlan0"

Replace [MAC_ADDRESS] with the MAC address of your wireless card. Reboot.

This worked for me on a wired card with my MAC and changing KERNEL="wl*" to

KERNEL="en*" on a bhyve Debian 9 guest.

It was asked many times on this list, and all around generally. Best answer

would be to look here:

https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfac

eNames/

It has full explanation of why those long names and what to do if you do not

like it. It is easy to assign shorter name, if you wish so and is explained

nicely, with 3 possible methods.

Neither the document or any of you have explained to me why on a single session

the same interface for a wireless connection would repeatedly change names.

wlan0 wlan0mon wlan0monmon ......  

Because on a different distribution the interfaces are 

enp0s25  for wire

wlp0s29f7u5 for wireless

and never change or drop their connection like debian has been doing for a while.

I go in Debian and try to do an update and upgrade in case the problem goes away

on its own.  When the connection gets dropped I leave and try again another day.

Did I mention that none of my other systems have systemd!

I have no idea whether it is related.
