Why does the download speed from the outside drop sharply?

Question

WiFi

Hello!
Tell me please, what could be the matter ... I
use WD Mycloud (3 Tb) as a home NAS, which is connected via Lan to a common network.
I launch everyone’s favorite torrent from a laptop, the first minute the download is more or less normal - 2-3 mb / s, after that it drops to 5-7 kb / s, and if you stop the download and resume it, the situation does not change in any way. Waiting and believing is already tired.
Why is that so, I don’t understand ... can someone tell me what the matter is?

Answer 1

Router for 300 rubles? Drive through the waffle?
Connect the computer directly to the network and check on it.

Answer 2

Just torrents? Just try to download a hefty file from somewhere. Maybe your ISP is bothering you.

Answer 3

It's stupid on my part, but you're probably right. The provider cuts the channel according to certain filters. I downloaded fresh ubuntu (for testing), everything is ok. The speed is stable in the range of 2-2.5 Mb/s.
Still watching, but it seems the answer was so simple. Thanks for the tip
UPDATE: no though... not an option at all. If you upload the same content to a hard laptop, then everything is fine and the download speed reaches 5 mb / s. so it's not the provider. The laptop, by the way, is connected over the air to the
UPDATE 2 network: strange behavior - the speed either drops to 9-9.5 kb / s, then grows to 5 mb, although then it again drops to 9-9.5 kb. Apparently all the same provider .... :-/
