Hello team,
Is there a specific way to enable a secondary wireless interface (via USB dongles) on DietPi in Raspberry Pi 4 B+?
I have a Alfa wireless card (AWUS036ACM, Mediatek) I’d like to use as main wireless interface, it’s recognized as wlan1.
I tried to add wlan1 configuration in interfaces.d, however the interface remains in down state.
Disabling the on-board wifi, caused by the loss of connectivity as I don’t have cable access (I have to remove dtoverlay=disable-wifi manually from SD config.txt to restore access.
Eventually, I would consider to keep both interfaces enabled.
Any hint or suggestion?
Thanks!
Can you share the configuration you did within interfaces.d
I was using the following:
Filename wlan1
# WiFi-USB
allow-hotplug wlan1
iface wlan1 inet dhcp
address 192.168.1.8
netmask 255.255.255.0
gateway 192.168.1.1
#dns-nameservers 192.168.1.99 172.31.0.2
pre-up iw dev wlan1 set power_save off
post-down iw dev wlan1 set power_save on
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
I also tried to specify SSID/PSK in wlan1 config, but no luck.
And what happens when you try to bring it up?
I see the following (basically no logs for wlan1):
root@DietPi:~# ifup wlan1
error: main exception: cannot find interfaces: wlan1
root@DietPi:~# cat /etc/network/interfaces.d/*
# WiFi-USB
allow-hotplug wlan1
iface wlan1 inet dhcp
#dns-nameservers 192.168.1.99 172.31.0.2
pre-up iw dev wlan1 set power_save off
post-down iw dev wlan1 set power_save on
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

I think you need to add auto wlan1 to your interface config, otherwise ifup can not find it.
Can you also share:

root@DietPi:~# sudo systemctl restart networking
ok I don’t have the same USB dongle but did a testing on RPi5 using following config
root@DietPi5:/etc/network/interfaces.d# cat wlan1
# WiFi
allow-hotplug wlan1
iface wlan1 inet dhcp

wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
root@DietPi5:/etc/network/interfaces.d#
at least after reboot I had 2 WIFI interface

and I could start wlan1 (even if not configured)
root@DietPi5:/etc/network/interfaces.d# ifup wlan1

Just wait a moment and do ifup wlan0 again
maybe it does not use the logical name wlan1?

Do you want me to run ifup wlan0 ? wlan0 is the internal IF
I was not sure if you had issues on wlan0 as you shared some error messages for this interface
Btw, you could try to upgrade kernel on your system to a new kernel structure that hast been introduced with RPI5, but is applicable for all RPi device Image | Raspberry Pi 5: Testing and firmware migration script · Issue #6676 · MichaIng/DietPi · GitHub
Just done it, nothing changed…

I used this dongle on other OS such Kali, but on Raspberry Pi 5. Haven’t tried on 4 yet.
??? I thought you are trying this on RPi4??
