As I see in wireshark, when my microcontroller sends an ARP request about my gateway it does not receive any response. It continues sending the same request for about 30 secs (the time I wasn't seeing any UDP traffic), and then it starts sending the UDP packet.
Sorry if I ask the wrong questions, but I haven't been monitoring this thread fully.
When are the ARP requests sent? In the middle of a transfer? Can you get us a pcap of that period? If it's in the middle of a transfer, it could well be that the ARP cache timed out and that there is some kind of bug in that handling for you. Which version if lwIP are you using again? (Again, sorry if I ask something already asked before...)
