Hello,
When my RPi3B+ boots up, the ethernet lights seem fine, used it to install NOOBs file install for LibreELEC. So it's not a hardware failure. As soon as LibreELEC starts booting it turns off. I am not able to see any kind of connection for wired connections. Have Ethernet enabled, also went from a RPi2 and the cable worked fine on that. So I know it's not an issue with the wire itself. I am now forced to use a Wireless connection when I don't want to.
@ LibreELEC 8.2.5
Thanks
