I used my MiniMX with libreelec 7.0.2.007 wiithout network problems long time.
One day i decide, try the wifi speed. It was disappointing , slow...
After that i delete the wifi connection, and switch back to ethernet.
Since that, always when i restart my box, always automatically turn back wifi setting, and turn off ethernet at libreelec settings.
When i change again, then work, but just to another restart. Then again the wifi enabled, and ethernet disabled.
How can i fix it?
