As the title states, my download speed goes down a few minutes after I open / restart the pc. From ~200 - 500 mbps when I open the pc to ~2 - 3 mbps after some time. Upload speed remains the same ~200+ mbps.


My PC runs windows 10, router Huawei HG8247H, wired, internet connection should be 500 mbps (fiber). Speed was tested on different sites, but mostly on speedtest. Avira as anitivirus. (not sure what other information should I provide).


My question is what should I check too see what is limiting my internet connection. Restarting the router doesn't change anything, only when restarting the PC the speed goes back to where it should normally be but after some time, (it depends a few minutes to 10 minutes) it drops to ~2 - 3 mbps.

What are you downloading at 500mbps or trying to download when the speed drops? Are there any other devices connected to the router at the time of testing?
