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
Entered password
By default was in DHCP.
Clicked Save
But nothing happened. It did not save. It did not do anything infact. Cancel was working though.
(Did try to save with security "none", but still nothing happened)
---------------------------------
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.
Powered up.
Tried to open http://runeaudio.local from Android phone.
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?
PPS - dont have HDMI monitor in my room. Router and TV, far apart.
