The MAC addresses are programmed during manufacturing test, and are supposed to be unique for each board. But since there are humans involved errors can happens.... If you send in the board we'll fix it. You can find out which board by comparing the MAC address with serial number on the PCB bottom, the ones that don't match is of course the ones that need to be reprogrammed.... Serial = hex2dec(20 lsb bits div 4), so 000024C862A0 should be 137384.
