I performed IEC61000-4-2 examination in a device using W5100, but connection of the LAN comes off during an examination when I connect W5100 to LAN of 100M, and there could not be the thing that a device recovers even if I finish an examination.
The situation that a device does not recover continues until hardware resets W5100.
When I connect the device to LAN of 10M, the device recovers after an examination, but the device is required to be connected to the LAN of 100M.
This phenomenon occurs in all devices which it produced.
How should I solve this problem?
