Just to create some order out of the chaos that is this thread:
I'm running runeaudio v0.4 on a raspberry Pi 2.
I ran volumio for multiple weeks.
I can get everything set up on cable.
I can set up a connection through the web interface.
I don't get an IP from the router on the wireless connection.
The web interface gives me this overview:
Name: wlan0
Type: wireless
Status: connected
Associated SSID: Ziggo89289
Assigned IP: none
Speed: 72 Mb/s
I still don't get an IP when I assign one manually. (I double checked the default gateway etc.)
I can ping my wired connection.
I can not ping the wireless connection.
I can not tracert the wireless connection.
I am able to get a working wireless connection on v0.3.
