Hi, amar. It looks like flash memory broken, I guess. If you have EVB, possible to re-write MAC Address using ‘MACTool for WIZ220IO’ program. If not, please RMA request to distributor. I’ve attached MACTool program in this post. MACtool_v1.0_WIZ220IO.zip (16.1 KB) Please try re-write MAC Address to WIZ220IO module. Regards, Eric.

Thanks Eric It has to use EVB to re-write MAC Address? Is it possible to just connect Module to PC in the same network and re-write it?

As you can see after program running, the MACTool program needs serial port connection. So, you should connect the module to PC using EVB - serial port for re-write the MAC address. Regards, Eric.
