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. >> me connection (ip route: nothing). >> >> I tried to ifup the interface: >> >> ``` >> $ sudo ifup wlan0 >> [sudo] password for desktop: >> Internet Systems Consortium DHCP Client 4.4.1 >> Copyright 2004-2018 Internet Systems Consortium. >> All rights reserved. >> For info, please visit https://www.isc.org/software/dhcp/ >> >> Cannot find device "wlan0" >> Failed to get interface index: No such device >> >> If you think you have received this message due to a bug rather >> than a configuration issue please read the section on submitting >> bugs on either our web page at www.isc.org or in the README file >> before submitting a bug.

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). > Or has the upgrade tried to revert the system back to a more > conventional ifupdown/wpa configuration in some way? 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. >> may 02 10:35:08 debian dhclient[6067]: Failed to get interface index: >> No such device >> may 02 10:35:08 debian dhclient[6067]: >> may 02 10:35:08 debian dhclient[6067]: If you think you have received >> this message due to a bug rather >> may 02 10:35:08 debian dhclient[6067]: than a configuration issue >> please read the section on submitting >> may 02 10:35:08 debian dhclient[6067]: bugs on either our web page at >> www.isc.org or in the README file >> may 02 10:35:08 debian dhclient[6067]: before submitting a bug.
