I tried the original direction by Frank.
1. Boot Pi3 with ethernet connection.
2. Connect to Runeaudio via iPhone using
http://runeaudio.local2. Find and connect to wireless connection (SSID) - tried both DHCP and static IP options
3. Saved wireless network profile; verified connection via green check mark
4. Powered off Pi3
5. Pulled out ethernet plug
6. Restarted Pi3
7a. Tried to connect to Runeaudio via
http://runeaudio.local - failed
7b. Tried to connect to Runeaudio via
http://(ip address from static IP option) - failed
One thing I noticed is that on the iphone the UI seems to constantly refresh the local connections available after a few seconds. I will connect to my wireless SSID, and the green check mark will show for a while. Then it refreshes automatically and the green check mark disappears. Also, there is a red X to the network in the profile on the wireless connection. And even if I use the static connection, the status will say no IP address was stored.
