How to check the reliability of the Internet provider and the speed of the Internet?

Question

Computer networks

Good afternoon, tell me please.
There is an Internet provider, and the tariff is up to 50 Mbps.
How can I check the real speed of the Internet connection. I know that there are various services like Speedtest, etc.
But rather, I’m interested in how to check this correctly, as I understand that before checking, you need to turn off all Internet consumers in the apartment (phones, tablets, TVs, set-top boxes (airplane mode, or off wifi), i.e. everything that can interfere with the check.
And how I understand ideally the same laptop where the checks are being directly connected to the incoming twisted pair cable to the apartment, i.e. without passing through the router.
And how reliable the measurement of this service will be.
It may be more correct to download a large file from somewhere and watch the download speed.
As I understand it, in my tariff I should get a download speed of about 6 megabytes per second

Answer 1

Download a large torrent with a popular distribution, with a large number of distributors (500-1000), and monitor the download speed. Torrent will squeeze everything out of your Internet channel.

Answer 2

What's the point of checking the speed directly if you turn the router back on anyway? If it does not pull the maximum provider speed - this is also worth knowing, IMHO.
The speedtest is quite suitable, there is no special point in bothering more for home Internet.

Answer 3

The speed check service that you indicated always shows correctly, with a loss of reliability of + -5%. So there is no need to invent anything.

Answer 4

Wi-Fi cannot be used at all when checking the tariff rate. Speedtest usually selects the provider's server as the server and shows the real speed. If you choose another server, then the speed is determined not by the provider, but by the server that sends traffic

Answer 5

1. The speed "up to 50 Mb / s" means exactly what is written - from 0 to 50 Mb / s, depending on various conditions. From the number of simultaneously working devices, from the load of the channel, from the load of the provider's channel, from the load of the end site, from the restrictions of the end site. This figure does not guarantee that you will always and everywhere have such a speed.
2. Reliability - 100% for this site. For another site - there will be a different speed. And generally speaking, the provider, even in flat mode, guarantees you speed only up to the connection point, at best - before leaving its network :)

Answer 6

It is important to understand that the provider will provide this channel. But will the resource from which you are trying to download something give such a speed. After all, restrictions often do not go on the side of the provider, but of the place with whom you communicate through the provider. Therefore, for the purity of the experiment, it is important to know that the remote server with which we are working gives such a speed. And between this server and you, all providers are allowed, and not just yours.
