It is difficult to answer because there is no symptom of how to die.
We need more information such as debug messages and packets.
It would be helpful if you could let me know your hardware environment.
The W7100A is a very old product based on the 8051, so detailed technical support is difficult.
Using another product, such as the WIZ750SR-100, makes technical support easier.
Samples of one or two modules are available.

Thanks Becky for reply.
We have disabled the ‘debug msg output’ in wiznet as a part of our requirement, so I think debug msg is not possible. We also disabled the ‘serial command mode’ as part of our need.
Is there any way I can read and write wiznet’s settings ?
Our HW is similar to the reference design of WIZ107SR, Do you have any particular question/s on HW environment ? I will connect to our HW teanm and let you know.

Bercky, I wanted to highlight what we observed on one of the failed boards.
Out of two, one of the failed boards have settings defaulted (will let you know the second board’s status soon) . We had changed following settings ip address, gateway, serial baudrate, parity, ‘debug msg output feature, serial command mode feature, serial data packing condition settings; all these settings are defaulted to its factory default.
Please note that the wiznet FW on chip is 4.06, hence noise on nFAC_RST pin should not be the cause of this defaulting situation according to user manual.
We also disabled the ‘serial cmd mode’, hence any serial payload should not cause this situation either.
Thanks.

Becky,
Have these kind of defaulting anomaly reported past on W7100A ?
Does Wiznet have any plan to release FW as a resolution.

Sorry lately reply.
please can you write tag as @becky ?
Not reported.
But i think this is due to unusual communication with the peer.
How many boards did you use?
As I said before, Please attach the packet captured on wireshark.

@becky
We are in development phase and using 2 boards ; both boards’ settings defaulted.
Do you want a wireshark trace exactly when the board started not functioning ?..OR any trace with normal communication operations in our application is fine ?

Yes, we should find the cause.
