The network order in the kernel is eth0(emac) / eth1(rtl8153) / wlan0, so I think it would be better to change it this way. Thanks, Chukun

I don't have a board at hand to double check, but the code I read here says otherwise: https://source.denx.de/u-boot/u-boot/-/blob/master/board/sunxi/board.c#L791-813 There it checks for up to four ethernet aliases and assigns MAC addresses to them, using the index in the lowest byte. So this would change the MAC address of the WiFi adapter. Am I missing something? > The network order in the kernel is eth0(emac) / eth1(rtl8153) / wlan0, Regardless of the fact that you shouldn't rely on indexes in device names, wouldn't that be that same, regardless of the order of USB and WiFi?

I'm very sorry for this, the rtl8189etv driver assigns the correct mac address to wlan0, so I didn't observe the mac address change. Sorry for my misunderstanding. Thanks, Chukun
