i don't think you've yet eliminated hardware issues - port on your router, and using a live boot disk... That's just basic elimination.

Also please post a screenshot of your task manager when the download speed has reduced (processes tab) organising any columns of interest high to low.

when the download starts:


when the speed drops to 0 b/s:

Do you have access to your router.

Check if somebody limited your connection. Connection can be limited to MAC address, IP address, and depeneding on router also by protocol.

I don't find any problems with my router or with IP or mac addresses, I tried to reset the router and the extender but nothing

The only odd thing I can see there- other than there's almost no download activity as we know in the 2nd- is the amount of GPU activity.

You can explore these as applicable: (ignore the strange '403 forbidden')
How to limit Internet bandwidth on your PC

403 Forbidden

to check these limits do not apply.

Check you have no throttling applied in Chrome:

No bandwith or data usage limit and no throttling on chrome

I was able to download a 500MB file without any problems, but when I try to download the same file again, the problem comes back and the speed drops to 0

Are you able to download a file from TenForums? For example: Please Wait... | Cloudflare

Yes, because this is a small file and i can download the file before the speed drop to 0. I can download big files from browsers only with a VPN

Something deliberately decreases the speed to zero.

yes but I don't know what. The last thing to try is a clean install of windows 10 i think

Have you tried safe mode?
