Runeaudio won't work after network change

Make sure your router is not trying to force use of AES encryption. I found my Pi3 showed as connected, but could not log on until this was changed.

I have no option to change AES encryption.
On router I can only choose between WPA2-PSK and WPA/WPA2-PSK.

I noticed some differences between Moode audio which works fine, and runeaudio which is not.
I don't know if it matters, but maybe somebody does.

When I put sd card with rune in my raspberry, I see a new network besides my network, called RuneAudio AP. (Access Point?)
But when I put sd card with moode, there is no new network.
Also it looks different on my router, because moode is on the same side as my pc, and rune is on a different side.
I don't know if it matters, but I hope somebody will.
Here are some pics to tell you what I'm talking about:

I could easily connect through AP, but as soon as I tried to connect to my home network, there were some kind of conflicts between networks,
I don't know how else to explain it. Like there was the same IP addresses of my router and of Rune Audio.
I changed the IP address in Rune network settings and then the problem was gone and it works fine now.
Strangly this happened only with Rune, I installed Moode and Volumio without a problem.
