So I just killed the last 4 hours trying to get my Netgear N150 working with Volumio. It turns out that not having a passkey set on my router was the issue (I live in an area without neighbors and it makes it easier for guests to connect). I selected the “no security” option on the Volumio network config screen and manually set all of my wifi details in /etc/network/interfaces, but never could get the wireless adapter to obtain an IP address (or probably even connect to the router).
Once I created a wpa2 password and added the details to Volumio I was immediately able to obtain an IP address and access Volumio as expected. So how do I properly configure Volumio, either through the network config page or manually editing /etc/network/interfaces, to connect to my router without setting a wpa2 passkey?
