Fast Internet, Slow Download Speeds?

So today my friend and I, who live in the same country, was downloading this file.It was around 6GB, which is irrelevant, but yea. It was from the same site, we have the same internet, yet he was downloading with 2.6MB/s while I was downloading with 1.338MB/s and it stayed like that for the remaining 40 minutes. Didn't even move at one point, while his went from 2.1 to 2.6 over 10 minutes. Worth noting, we use the same ISP, he only have 25/2 while I have 50/5, and I could easily download 2 files with the exact same speed (1.338MB/s each but not 1 with 2.6MB/s or more.There's also a client downloader, for this game, where he again got 2.6+ whereas mine always stayed at an amazing 80-180kb/s. I tried disabling anti virus, firewall, Malwarebytes, nothing changed it. I know you're thinking it's just the seeds or site that is limited to an x number of download speed, but it really can't be the case in this. It happens with every site I try. It's always at 1.3xMB/s and never moves regardless of how good it is.

I honestly don't remember, but I don't think this happens when it's a .torrent file, using programs like uTorrent with good p2p. It happens in all browsers, and apparently game client downloaders.I can download 5 different downloads at 1.3xMB/s using all of my available internet, but when it comes to a single file, it for some reason, is impossibleI'm not complaining about the download speed, but it just seems like there's something wrong. My downloads also have a habit of failing in chrome after a few minutes, for no reason. That only happens from some sources though.
