There is no such thing as a baud rate for a TCP/IP connection. That term only applies to serial connections. For TCP/IP connections, you are using your ethernet port, so that could theoretically be 10 megabit/second, 100 Mb/sec, 1 Gb/sec. But of course you are sharing that with all other network activity your computer is doing, and also any other network activity between other computers on your network segment.
