Hi, I’m sorry to hear that. the flash memory in which the mac address is stored may broken. Anyway, I will help you to change the mac manually. Please refer to attached firmware and guide video. wiz100sr_mac_change_v0514.zip (2.0 MB) Upload firmware v0514 Turn off configuration tool - this is because you can not open the same port. UDP socket open in terminal program like ‘Hercules’ Send command that is “MACC(old MAC)(0xff)(new MAC)” like this → MACC$00$08$DC$11$22$33$ff$00$08$dc$44$55$66 Check the massage that module responded Check the changed MAC address in the configuration tool and debugging messages. Please try and notify to me the result.
