W7100A-S2E Firmware

Hi,
we have bought this chip with the firmware v. 3.14 preloaded.
Do we have to update at the version 4.03?

I have seen that this version is for WIZ107SR with HW ver 1.4, I use the W7100A-S2E on my custom hardware.

Best Regards,
gbit

Hello,

You can use FW 4.03 on your W7100A-S2E.
If you can search W7100A-S2E with WIZnet’s Configuration tool, then you can upload a new firmware onto W7100A-S2E.

Thank you.

Hello,

Please refer to the below link to rewrite MAC address on your module.

And to avoid this issue happens again, please update your module with the latest firmware, V4.06 after writing MAC address again.

Thank you.
