Prompt the utility for imitation of bad connection. I would like to check the web application for such things:
* Packet loss
* Broken packets
* Lost connection

Optional:
* Simulation of overloaded WiFi
* Simulation of low speed

If you have Linux, then it seems like tc should help

It is a pity that rfc748 was brought to mind in this way - this is exactly the same case.

On MacOS, ipfw. Lots of different settings. Example:

sudo ipfw pipe 1 config bw 128Kbit/s delay 120ms
sudo ipfw add 1 pipe 1 src-port 80
sudo ipfw add 2 pipe 1 dst-port 80

It is possible to simulate various internet connections in the chrome debugger.
Also, in addition to chrome, I use the netlimiter 3 tool - in which I set the outgoing and incoming speed myself

An RF generator can (any transmitter) simulate radio frequency interference noise
You can connect the cable cores through capacitors in this way you can simulate a bad or oxidized contact
and see in Wireshark how much is lost
