To tell you the truth, I don't know. This is normally a bit too low-level for me.
More or less I moved on, because even if I had seen a problem within the TCP 
packets, I still would have been unable to fix it. If you are interested, I would start 
wireshark again and check for the PSH flag and ACK packets. But not before this weekend. 
I don't think it is a problem in my code or in Qt, else the E series should be affected,
too.

Yes. When I do a QTcpSocket::write(const QByteArray & byteArray) the correct number
of bytes written is returned.
