The MAC address you have chosen is LAA (0x12). No idea how it impacts the workflow, but you can try changing it to UAA. Your screenshots suggest that W5500 does not even try to connect to the server, however it depends on where you have Wireshark listening to traffic. ARP is broadcast, while SYN is unicast, and if you listen on another device than W5500 and server you may not see targeted traffic.

w5500의 네트워크환경이 정상적이라면 wireshark에 “SYN” Packet이 나와야하는데, 캡처된 화면에서는 ARP request/reply만 있습니다.
W5500(tcp Client)이 TCP connection 동작시 ARP request/reply 이후 SYN 패킷 이 W5500에서 발생해야합니다.
해당 부분 확인해보시기바랍니다.

핑에 대한 응답이 현재 확인이 되질 않는데요.
일단 보드를 새로 제작해서 테스트를 했는데도 동일한 증상인 것까진 확인하였습니다. 추가로 더 확인할 부분이 있을까요? PCB라우팅에 따라 수신이 아예 안되는 경우도 있는지요?
