I have had a problem with wifi here, and not sure it is sorted yet, but since a few days ago my android tablet could not connect to runeaudio.local on the pi3 by wireless. I have a genuine raspberry pi wifi dongle, and the only way my android devices could connect to rune was when or if I hardwired the pi3 next to the router. As soon as I disconnected the ethernet cable , then runeaudio.local was not accessible. I have also tried by ip address, and well as a new installation of rune on the sd card, and nothing will connect by wireless.
Is it possble the wifi dongle has gone kaput, but I have 2 of them, and can't see both going wrong at the same time.
