These are the steps I took
Put the SD card in Pi3
Connected Pi3 to my TV with HDMI.
Connected USB keyboard to Pi
Powered up using official Pi adapter.
First boot happened.
Went to Menu > Network > WLAN
Selected my wifi network.
Changed Security to WPA2
By default was in DHCP.
There is a known bug in Runeaudio where to save as DHCP, first static needs to be selected, some random values changed and DHCP selected again from dropdown to make the "Save" button work. Clicked Save
It showed that my network is configured but when tried to connect,
nothing happened. It did not connect. It did not do anything infact. Cancel was working though.
Then later, disconnected Pi3 from my TV and brought to my room and connected a ethernet cable to the Pi, as was written in the docs.
But again, nothing happened. Browser simply said, can't connect. page does not exist.
Please tell me how to make this work?
PS - why does the runeaudio show Pi2 as hardware-env, when it is in Pi3?
