Hi,
there is some bug that you cannot setup wifi directly by using keyboard, mouse and HDMI monitor - basically the wifi profile is not saved.
You have to connect RPi to wired ethernet and use another device on the local network to setup wifi remotely (use PC,tablet or mobile phone, via its browser-> http://runeaudio/ or look at router for assigned IP address.).
So, when you connect remotely, setup wifi, save profile, reboot and check status of network - both (wired, wifi) should be enabled.
Then you can shutdown system and disconnect from wired network and enjoy wifi.
