Thanks for the hint, I'll give it a try.
Sometimes (but not always) my wifi adapter doesn't build up a connection on startup. It happens randomly, I can't reproduce the failure. When I then establish the connection manually, it works.
I'm running libreelec since 2 years now and the problem exists since the beginning.
Here are my logs:
systemd journal: http://ix.io/2wJJ
My system is a ThinkCentre M73 - Tiny Form Factor with Intel Core i5-4570T Processor and 4 GB RAM, without built-in wifi
Wifi adapter: TL-WN823N
LibreELEC (official): 9.2.4
I hope, you can help me finding a solution to this problem!
Thanks and regards
