The MAC of my WIZ108SR board has changed to FF:FF:FF:FF:FF:FF after a factory reset. Although the configuration tool can detect it, I can’t ping it any more. please help me to put back the MAC address (wich is written on the board). My upload is also not working. When I press upload button it says "the destination 192.168.0.102 (I was able to change it) is unreachable. Please check if the device is in the same subnet with PC! " although it is in the same subnet.
