Hi, Check if at "System-Libreelec-Connections-Yourconnection-Edit" the "Connect Automatically" is enabled.
Many times when the network connection is edited, that changing to "off" and need to enabled again.
Hi VLouis,
thank you very much for your idea.
I found the option but it already was enabled.
After a black-out/ hard shut-down the Pi, the wifi says "failure". After choosing the "connect" option manually, the wifi is marked as connected without any problem.
Could you or anybody else please test it? Just switch off the power and on again, and see what it does?
My Pi is newly setup with LibreELEC 9.2.4 which is the last recommended version for the 3B model.
