MAC Address issue - OPi Zero H2+ (Armbian Debian Stretch)


#1

Hi,

I have an inquiry regarding this matter.

I am having USB Wifi Dongle installed @ my OPi Zero H2+. It has built-in NIC (Eth0 & WLAN1) for the Debian Stretch.

I am using this PI for the FlightAware purposes.

  1. I connect to Eth0 from the beginning to access SSH and update all required updates.

  2. I use nmtui for the USB Wireless connected to the Wireless AP.

  3. Reboot the PI.

  4. Install my PiAware 3.5.3 as per their instruction.

  5. All Installed without any issue.

I noticed that the MAC address of the USB Wireless Dongle is as follow:-

wlx7c8bca1f3ad1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.194 netmask 255.255.255.0 broadcast 192.168.1.255
inet6 fe80::1b71:b02c:b5dd:22f9 prefixlen 64 scopeid 0x20
ether 7c:8b:ca:1f:3a:d1 txqueuelen 1000 (Ethernet)
RX packets 10302 bytes 2304649 (2.1 MiB)
RX errors 0 dropped 391 overruns 0 frame 0
TX packets 3567 bytes 1221201 (1.1 MiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

Built-in Wifi:-

wlan1: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether 12:42:2f:e3:99:f8 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 ( 0.0 b )
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 ( 0.0 b )
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

On Board Ethernet:-

eth0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether 02:42:2f:e3:99:f8 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 ( 0.0 b )
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 ( 0.0 b )
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device interrupt 37

Now I want to set the wireless router to forward the port (SkyView Page) and I tried to put my USB Wifi Dongle MAC Address “7c:8b:ca:1f:3a:d1” but end up and it link/loop to the eth0 MAC Address “02:42:2f:e3:99:f8”.

What should I do to resolve this issue?

Another issue is how to disable the built-in wireless NIC permanently as the built-in is poor in connection.

Thank you.
