Reduced speed. How to prove to the provider?

Question

Computer networks

They like to delete questions here, but I'll try.
The problem is two weeks old. The network does not disappear, but it is terribly slow. With the declared 3 Mbps (or 300-400 kbps in the phone in the upper curtain), the speed does not rise above 1 Mbps and this is still a good speed for these two weeks. The most constant speed is up to 20 kb/s. On YouTube as 144p videos freeze. Pages take half a minute to load, images even longer. The provider is certainly not a gift, but when they apply, they always come, look, and here

Dear subscriber, there are
no problems on your port. There is a periodic load of outgoing traffic from you. In this case, there is a problem with speed. Perhaps at that moment you were using a torrent client or uploading something to the network.

and in HP recommendations for settings, look at the cable, etc. Torrent nothing to do with it, the problem remains even when off. comp. checked for viruses. How to identify the cause or prove to the provider that the speed is underestimated?
Maybe there is some kind of program that will send requests to the Internet, let's say every 5 minutes. and monitor the speed for some time? To then show them these statistics.

Answer 1

Somehow I monitored:
https://github.com/sivel/speedtest-cli
https://linux-notes.org/ustanovka-speedtest-cli-dl...
https://xakinfo.ru/2017/11/ speedtest-cli-zabbix/
But you need to be sure that the cable (if the Internet is on the cable) from your side is not damaged.
There are usually twists in the shield, it is desirable to solder.
Read the agreement with the provider "about speed"

Upload: 51.04 Mbit/s

Answer 2

If you have a speed limit in your contract, then ask your provider to measure and check it.
I advise you to take measurements on each network segment and determine its bottleneck. Perhaps you have a problem. Perhaps a problem with the neighbors. Perhaps the operator does not care about you and he simply connects everyone he can into his narrow channel.

Answer 3

I came like a month ago to connect the Internet to one office, they took 5mb / s. I connect everything okay "test" I say. He measures the speed and he has less than a megabit and says "you have something bullshit and not an Internet" and I look at his entire PC fleet on win10. I mean, I go into the updates, and there already 30% have been downloaded and I think "you have bullshit." I cut down and show everything on my laptop. Conclusion, before chasing the provider, check your side, the provider tells you that you are loading the channel

Answer 4

Wangyu wifi at 2.4Hz and win10?

Answer 5

Isn't it easier to change providers? Why prove? It is he who will lose money if you switch to another provider. And you will keep your nerves in order and not toil with nonsense
