router - Simulating a bad internet connection

Question

I'm developing an embedded device which has access to the internet through LAN. I'm in the testing phase now, and I would like to test how the device performs when the connection to the internet is poor. Currently, the device is connected to a router through a hub, which I use to monitor the packets with Wireshark. What's the best way to throttle down the internet speed of the device to mimic a scenario that may happen?

Can I do it through a PC? Do I need access to the router? If so, is it possible to limit the speed of each IP in the router interface?

Actually, a friend suggested that I will purchase a usb2lan ethernet card, and to bridge the PC lan connection to the embedded device, and then using a software QoS limiter. do you think it will work ?

Answer 1

You can try using "Fiddler"

You have options to simulate bad network (like old modems 33k or 56k)

You need to plug in your device to your PC and turn on the proxy (every request will be transfered through Fiddler)

Then you could test your code with a bad network then see what happening ;)
