Hello Tek
Thanks for the support.
My code does not connect to any other machine, just the PC for syslog using your code.
It is often the second, third or fourth message that disappeared. After that, it is more stable.
I have too already seen some rare disappeared messages when sending a lot of it on A press.
Have you tried to press very quickly the A button and sending eachtime 5 or more messages ?
anyway, that s a good news if you cant reproduce the problem, it probably comes from my router or my Vista.
I have just swap to a USB/Eth adapter and not sure I have reseen this issue.
Perhaps just to be warned in the doc.

I hate to have to tell you guys this, but udp is a best effort protocol, losses will happen once in a while.

Why don't you use TCP? Am I missing something here?

I am not even sure if the syslog protocol supports tcp.

Syslog messages can be sent via UDP and/or TCP.

The plain old syslog protocol is actually UDP only, but there is a new standard which use TCP. The drawback of the TCP standard though is that it uses XML (I took a quick glance on the public draft version of the standard), handshakes and even more data fields thus making it a quite complex protocol. However, I see the problems that arise due to the use of UDP and I am thinking of creating a simple protocol for Syslog over TCP. Maybe just adding a terminal character (NUL byte) or a small size header (2 bytes) still preserving the Syslog payload.

I am sure that there was another IP using protocol like tcp, but with packets, and wikipedia seems to know of it.

I don't think SCTP would be any better than a custom protocol. It still is non-standard for Syslog and vanilla linux and windows installations don't support SCTP AFAIK. Plus I'd have to add SCTP support to my Wii code.
I'm working on another, completely custom and really simple protocol using TCP, maybe offering secure authentication and encryption / compression if I find a simple way to do it.
