Windows simulate network cable loss

Question

I'm trying to program some tool and i want to simulate a network cable lose with it. So i want to get the same effect like i unplug the networkcable from my computer and plug it in again. It's not the same as the '/renew' / '/release' commands. When i disconnect / connect it manualy it look likes windows remember some things and it's connected very fast back again. Is it possible and maybe how to do it in code?

Thank you very much!

edit: I found another program that just blocks all ports, this is ok for me too but how to do in code :).

Answer 1

You should set the fetch and send data bitrate to 0

Alternatively you could just set the receive bitrate to 0 bits and leave the send untouched this would also simulator the same.

Answer 2

Check out a great little tool called WANem . You can use it to simulate different WAN scenarios. Loss of connectivity is one possibility, but also jitter, noise and more on the line. Even simulating a dial-up connection. Runs as a bootable ISO and very easy to use.
