The same problem. I think solution is still unavailable. Reasons too. I made some tests and noticed that hang time is heavily depends on traffic. Then I've tried to connect to server and send message every 100 ms it hangs very very fast: just 10-20 minutes. With time interval 500ms hanging come only after few hours of work. Maybe it some problems with TCP stack? Or maybe I've missed something in TCP/Ethernet controller  initialization? There was opinions that with 3.4.1 all was OK. Really? Appreciate any suggestions.

    With respect, Sergei.
