W5100 won't connect when ping times > 200ms

Does anyone know why the W5100 (TCP Server) does not accept connections when the ping times are long (>200ms)? Short ping times (<100ms) are ok.

We tried setting the Retry Time Register to 800ms and the Retry Count Register to 255 and the issue still occurs.

Thanks.

Hello.

RTR sets initial value of Sn_RTR (SOCKET n Retransmission Time Register). The unit is 100us.
RTR and RCR (Retransmission Counter Register) set ARP & TCP Retransmission.

Thank you
