[Pkg-utopia-maintainers] Bug#950276: network-manager: nm fails to establish connection using usb wlan with predictable device name

[Jürgen Bausa]

Package: network-manager
Version: 1.14.6-2+deb10u1
Severity: normal

Dear Maintainer,

nm is working well with the internal wlan (intel). However, using a ralink usb stick, it fails to connect

like Jan 30 21:36:41 lina NetworkManager[663]: <info>  [1580416601.5122] device (wlx7cdd902eXXX): supplicant interface state: ready -> authenticating
Jan 30 21:36:41 lina kernel: [ 1157.342652] wlx7cdd902eXXX: authenticated
Jan 30 21:36:46 lina kernel: [ 1162.344096] wlx7cdd902eXXXX: aborting authentication with 98:9b:cb:12:XX:XX by local choice (Reason: 3=DEAUTH_LEAVING)
Jan 30 21:36:46 lina NetworkManager[663]: <info>  [1580416606.5911] device (wlx7cdd902eXXXX): supplicant interface state: authenticating -> disconnected
Jan 30 21:36:46 lina NetworkManager[663]: <info>  [1580416606.6926] device (wlx7cdd902eXXXX): supplicant interface state: disconnected -> scanning

This seems to be connected to the long (predictable) device name. If I use an udev script to create a shorter 
device name (like usb-wlan) it works perfectly.

I am not sure if this is caused by nm or some other component.

I found several postings of this problem on the internet (from 2017, stretch), but I did not find a bug report in the debian data base.

Regards,

Juergen
