WiFi interface as primary interface

Dear All.

I know that this topic has already been discussed, I tried to use these posts, but the solution given in them does not work. I can’t connect my volumio to Internet using only WiFi Interface. I’ve simple wifi with WPA2 ssid, I don’t know what is going on. Please help.

I have tried a few of the methods described, but mainly two:

  1. Put information to /etc/network/interfaces file
    auto wlan0
    allow-hotplug wlan0
    iface wlan0 inet dhcp

#wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

wpa-ssid Example

wpa-psk 00eadc8116e7b5bceaf056c5a6cad7b49684b3a99f4acf02078943c85b36fd5c

  1. by using wpa_supplicant file


May have volumio somethink like raspi-config or somthing similar to auto configure wifi ?
