Hi,
i know this is an old thread, but i'm having the same issue, except that tethering is not enabled on my libreelec.
My setup:
Raspi Zero, TP-Link TL-WN722N. Librelec 7.0.2
With my Edimax the Wifi works fine, but the TP-Link doesn't seem to associate with the Wifi.
Can anybody help me? What information do you need?
Thanks in advance
