[xubuntu-users] Intermittent wireless connection

[Karel P Coors]

Hi all

here is an issue about which both in Xubuntu 16.04 and Xubuntu 18.04 
there are lots of articles and proposed solution . None have proved to 
work for me. Grateful for your time and suggestions.

Here an example of the error: $ journalctl --follow
