I am trying to make a WiFi router from NanoPi M1+ device. It will have two working modes that is Eth<-->WiFi and WiFi<-->WiFi.

I am able to execute the first mode perfectly, but the second mode where the device has to work as a station and Access Point is troubling me.

The NanoPi device has a built-in WiFi chipset and I am using an addition WiFi adapter for another mode.

The issue is, the device is unable to show the second WLAN interface. On manually adding an interface using iw it throws an error.

I have included the output of the commands in the following.

ifconfig:

The wlan0 interface should work for Access Point mode and wlan1 interface as a station.

On doing :

iw dev wlan0 interface add wlan1 type station flags none

throws an error:

command failed: Operation not supported (-95)

I added wlan1 as an interface in /etc/udev/rules.d/70-persistent-net.rules file, but still wlan1 can't be recognised.

SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="C0-25-E9-25-AB-14", NAME=="wlan1"

SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="b0:f1:ec:2c:ea:c6", NAME=="wlan0"

Please tell what I am missing and how can I add wlan1 as an interface?
