Network speed problem

[Idlexlol1459]

So I have a 120mb/s of download from videotron (wich is stable) that gives me a real 15mb/s of downlaod on my pc normally
but strangly I have some weird speed drop on some sites/ application / game
LIke on steam(game Provider) I download at 16mb/s but if I try the ookla speed test like any other test I have 1-2 mb/s of download and lower
On Origin, when I try to play a game (Battlefield) it can't connect to servers
But I could download the game at 16mb/s
It always says there is a problem of ping with servers

It doesnt look like a problem that happens sometimes it always do this.
And I tried many things like
Resetting Router
resetting computer
changing cable
Downloading latest ethernet driver

If anyone know anything about this
I would appreciate the help

you have 120Megabits per second, but steam is downloading ay 15 megabytes per second.

 

Those speeds look correct.

This is what works , on internet , while playing games , speed test , the download speed / Upload speed is really bad ,

But when I download the games it goes fast .

This is my problem , it isn't a problem of sometimes, it is always like that !

But you can see in the screenshot, i download fastly.

(Both speed has been taken the same momment)
