WIZ750SR-100 Keep-Alive and firmware update not working

Hello,

I am testing Keep-Alive feature on a WIZ750SR-100 and it seems not to be working properly. If I unplug the network physically, the board does not close the socket and I have to reboot it. Could it be a known issue fixed on the newest releases?

On the other hand, I am trying to apply the last available update (1.3.3) with WIZnet S2E Configuration Tool V1.4.1. I am getting an error “Firmware update failed” and the board stucks on “BOOT” status.

I have checked port 50001 with Telnet and it has connection, but port 50002 seems to be unavailable for some reason.

Any ideas? Do I have to do something else?

Thank you in advance.
