after some further investigations I managed to install drivers for this dongle, and setup a wifi connection, but connection it’s not working yet.
to install on volumio 2 the drivers for the official raspberry pi wifi dongle WLU6331 (chip Broadcom BCM43143) I did:
cd
sudo su
git clone --depth 1 git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
cd linux-firmware
cp -R * /lib/firmware
reboot
to configure wifi connection (a WPA2 in my case):
nano /etc/wpa_supplicant/wpa_supplicant.conf
network={
ssid="YOURWIFINAME"
key_mgmt=WPA-PSK
proto=RSN
psk="YOURWIFIPASSWORD"
}
and
[code]nano /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
allow-hotplug eth0
iface eth0 inet dhcp
auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf[/code]
with these settings I get an IP for eth0 and wlan0 from dhcp, and both interfaces show up correctly in ifconfig, but ONLY eth0 actually works:
[code]root@volumio:/home/volumio# ifconfig

with wlan0 I can correctly scan wifi networks:

BUT:
wifi connection is not able to actually receive packets (in ifconfig wlan0 has dropped packets), so it’s totally unusable.
in fact dmesg shows repeated errors:

I investigated on google each one of these errors, but found no suitable solution to the problem.
Also tested the same hardware with raspbian jessie lite, and wifi works fine. so it’s only a volumio 2 related problem?
I’m stuck on this problem, hope someone could help, otherwise I’ll have to buy a different wifi dongle to use volumio
