Howdy folks!
Long time lurker, first time poster as I'm at my wit's end. I've got a weird one for you guys. I pay for 400/20 (Mbps) from my ISP (Spectrum), and a speedtest shows I get about 485/25 (Mbps, both from the Microsoft store Speedtest app and then website using Chrome). Problem is, whenever I go to download anything from any source (Steam, Battle.net, Chrome, Microsoft store, etc.) my downloads seem to hit a hard cap at ~160 Mbps/~20 MB/s. If I go to my other PC's (this is on my gaming PC, I have a dual PC stream setup and also an Alienware 15 laptop as a media PC) I can download things without a problem, reaching speeds in excess of 400 Mbps/50 MB/s.
Gaming PC (the problem system) has an i7 5820k that never seems to break 30% utilization while downloading, stream PC has a Ryzen 7 2700x, and Alienware 15 has an i7 7820HK that hits anywhere from 60-95% utilization while downloading, so it can't be a problem of the CPU not keeping up with the downloads. Gaming PC is also downloading to an Intel 660p, stream PC to a Samsung 970 EVO, and the Alienware laptop to a Seagate 5400 RPM HDD, so the storage can't be the bottleneck either.
I'm genuinely baffled as to what is going on, and would love some input from you fine folks. I'm 23 and have been building and messing with PC's since I was a child, and I like to consider myself fairly well versed in this stuff. If you guys have any idea what it could be or if I'm overlooking something, I would super appreciate the help!
Thanks guys!

I was thinking this could have been it, but I can almost guarantee this isn't the issue. Downloads work fine on all other devices on the network. It's solely my gaming PC that has the issue. -Anthony
