I'm using Kodi with Libreelec to convert an old radio into a music system using a HiFiBerry amp. Everything works well and the Kore app allows me to play music and radio. However the radio was a birthday present for my son and the Kore app on his phone will not connect with the radio at his house. I want to edit the configuration file on libreelec with details of his SSID and wireless network password but I cannot find where it is stored. Normally on the Raspberry Pi the wireless configuration details are stored in wpa_supplicant.conf but I can't find this file. Does anyone know where libreelec stores the wireless config?
