The MAC address of my new X20 boards keeps changing on reboot or even when disconnecting and reconnecting WiFi. For example, yesterday it was 00:08:22:74:f3:06, while today it’s 00:08:22:f6:e5:fb (i.e. the second half is different). As a consequence, I cannot enable remote access to my boards (IP address reservation + port forwarding). Please help!
