@ Millhouse, thanks a lot you are pointing in the right direction, even with Raspian there is no Wifi, so I will check further independend from LibreELEC.

A clean installation of LibreELEC 8.2.5 (from img.gz) is known to have working out of the box WiFi on RPi 3B, so test that also (without any other devices attached to USB or GPIO) and if WiFi isn't working with LE 8.2.5 then I'd suspect a hardware failure (could possibly be power related, so try a new/different power supply too).

If your wifi is working with LE 8.2.5 but not current LE 9 test builds and the problem exists with Raspbian too, then it might be best to open an issue here:

https://github.com/raspberrypi/linux/issues

Post the Raspbian dmesg output etc. on the issue, as it could be a kernel issue.

However, than you very much again for your support and for maintaining this great distribution, I gave a LibeELEC raspi to my family one year ago, an it is in use quite frequently, so thanks for all your work.

It's a team effort, but I'm glad you and your family enjoy it!
