Go to other websites, like Microsoft.com or Majorgeeks.com, anywhere that has larger downloads, and try to run a download, any file bigger than 500mb.
Watch download speed and stability.
Then call your ISP and demand to know why they lie about not throttling
He is not talking about DOWNloads and i don t think they ld throttle http Bluey but either way it can be quite hard to get microsoft to download from you (other than statistics etc)
You might want to go to speedtest.net and see what happens but even that will not detect throttle
Maybe a peek in your router log would tell you something more? worth a shot i guess
is there any other program running when this happens that could hyjack the uplad bandwith maybe? try shutting all other programs you can think off
I hope this helped a little, Greetings,
