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

 

I did some further testein, as I have 2 Raspi 3 B Rev 1.2 boards, on the one Wifi is working with my LibreELEC image as well as with Raspian, bit not on the other. There might be one year between the purchase of the two, so it might be related to firmware (not working on the older one). However, Wifi connection is way too slow (2-3 MB/sec), wo seems I will stay with WLAN repeater and LAN from WLAN Repeater to Raspi.
