wlan stick for pi 3 + volumio 2

Help and Support Help

Hey everyone!

I just bought a wlan stick as my pi3 is going to get a metal case, so the internal wlan won’t be the right choice.
when i plug the stick in an boot, i can see the wlan1 already using ifconfig -a

wlan1 Link encap:Ethernet HWaddr b8:27:eb:07:54:c8
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:18 errors:0 dropped:18 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:4526 (4.4 KiB) TX bytes:0 (0.0 B)

Now i am not sure how i can manage to disable the internal wlan0 and use wlan1 as the standard wlan interface. The wpa_supplicant.conf already has the right information (as wlan0 is connected).

i tried to replace “wlan0” with “wlan1” in the /etc/network/interface file but nothing changed. I also tried to add wlan 1 there

auto wlan0
auto wlan1
auto lo
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet manual

allow-hotplug wlan1
iface wlan1 inet manual

Can someone tell me what i am doing wrong?

Ok, i found the solution although i am not sure if this is the proper way…

change /etc/network/interfaces to

auto wlan0
auto wlan1
auto lo
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
wireless-power off

allow-hotplug wlan1
iface wlan1 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

important was to change iface wlan1 inet dhcp because using “manual” also for wlan1 did not work (why?)
Anyway, now it uses the exteral usb stick and the internal wlan0 is disabled (at least i hope so…)
