Okay so
Some days ago,
a week or so, I noticed that I wasn't able to use netflix because of too low internet connection.
I have a bad connection but it had never prevented me from watching and I could still use youtube and surf without experiencing any kind of slowness.
I also noticed that skype wasn't working because of the same reasons, then teamspeak, then online games. ( I don't think it went gradually, I just noticed it one after another.)
So I used resmon using windows + R and I saw that , even if I had available bandwidth, some things weren't using it.
Please, I need some help with this. I don't really know what info to put in so if you need something just ask me.
I've also done this :
