I’ve noticed that if I use the scheme PC-Ethernet-Router-Ethernet-W5500 (I) all comunication is OK, but on using PC-WiFi-Router-Ethernet-W5500 (II) all fails, even ping. Wireshark analyse showed, that in scheme II ARP packet has 18 padding bytes, and w5500 ignored these packets. I tried 2 development boards with w5500, with the same result. Please, advice what to do for getting reply for type II packets. Wireshark log and screenshots included.
