Hi, David, and thanks a lot for your help!
Literally means:
$ sudo apt-get update && sudo apt-get dist-upgrade
Afterwards:
$ sudo apt-get autoclean && sudo apt-get autoremove
This is what I do normally.

Indeed^2.

Have no idea. Maybe I did something in an improper fashion...
In fact, can't recall touching nothing about systemd-udevd.
Should I?

I still have the file:
```
$ cat /lib/systemd/network/80-iwd.link
[Match]
Type=wlan
[Link]
NamePolicy=keep kernel
```
And in /etc I only found:
$ sudo ls -aR /etc/ | grep iwd
iwd
/etc/iwd:
iwd.service
But nothing I remember to have created (at least manually).

Maybe, that's one of the things I'm trying to rule out/discard,
but can't think/know of a way to check it.
If the USB-port makes an unstable contact, could that connect/
/disconnect make the system assign new name to the dongle in
each iteration? (Just an idea...)
It has not happened again since the last occurrence, couple of
hours ago.
