Hi, hope this wasn't arleady solved (and its not too "duh" to ask, but...as a noob, I can't really tell).
Context: 9.2.1 running on a RaspberryPi B 4, flashed it on my card, connected, booted quite easily. After booting, as I go to the Libreelec add-on settings, I can see all my wi-fi connections (I run both 2.4 and 5.8 on my router. In a few seconds, they disappear one by one leaving the page empty.
If I connect my cable, it works perfectly. (In the Network menu, both wired and wireless networks are switched on active, including tethered access point). I reboot the Raspberry, and then the page is empty since the beginning.
At first I thought it was an harware issue, so i flashed raspibian on the same card, tested it and had no problems on the wifi at all.
What might be making the wifi connections "disappear" this way?
I checked on previous threads but in most cases wifi issues were related to wifi sticks and in general wifi not working at all.
Thanks for your help.
