after problem with e2 I was thinking, maybe e3 is better, at least it is newer!
I of course do not want to search for the IP number every time I want to listen to music, therefore I want a fixed IP number.
I click settings, (the cog wheel) then Network, and after that click on the network number, then I can check "static IP"and OK. after that I fill in the IP number, and the browser goes blank becouase the server has now a new IP number. I wait 10-15 minutes but I can connect on the new fixed IP number, neither on the old one.
After a while source a monitor and hook it up. The raspberry is running with the runeAudio screen is running. then I hook up a mouse to check the network setting. THis is almost not possible because I have no mouse pointer , strangely enough and the color scheme makes it almost impossible to recognize anything. Anyway somehow, after many many trial and errors i finally get to the network setting and there no IP number whatsovever is shown, only the MAC-address. so this rern e3 version, does it support fixed IP or not? the old beta 0.3 I used with fixed IP, and it did work, I tested that today.
