wow, great thanks. I'll make some tests tomorrow. Indeed, I forgot to mention. I'm using TCP with the netconn API. While reading through the multiple posts I missed the past few months, I found out that 1.3.2 is out and Atmel framework 1.7 too. I'll upgrade everything tomorow.
But in the meantime, I'm experiencing problems like I wrote. I don't know why my app is hanging in the tcp_in.c file. If somebody knows what's going on on that line, let me know.
