Question

I got 2 x Orange PI pc+ running Armbian (install by same SD card on eMMC). My two orange pi pc+ got same wlan0 mac address. I did research on forum and saw some suggestion about bug of Network-Manager. 

I try remove (purge) Network-Manager but see no difference.  I also try look in u-boot but don't know how to set mac address on the u-boot part.

 

How should I make my 2 pc+ board have difference mac address? want to run these two board under the same wifi network.

 

Please suggest. Thank you very much in advance.

I created a patch for a wifi driver which makes mac generating unnecessary and eliminates the problem you experienced:

https://github.com/jernejsk/OpenELEC-OPi2/blob/785fc6c4f88c2cc3e01244069ffb50663c50ffb3/projects/H3/patches/linux/linux-200-wifi-mac-fix.patch

 

Allwinner function is used which generates wifi mac based on sid data. It differs only in one bit compared to ethernet mac but it is enough.

 

@Igor,

you can apply it if you think it is useful... It will certainly simplify build script a bit.
