So today we decided to upgrade our internet, went from 200mbps Download to 400mbps Download and from 20mbps upload to 40mbps.

The uploading works fine on both PCs, a solid 40mbps upload all the time but the downloading speed is a whole other story, on one PC it keeps getting upto 170mbps MAX all the time on another PC it reaches 400mbps every time. Switched cables(cat5e) already, plugged a cable straight from the modem into the PC, reset our modem, reset the network settings on the PC itself, updated my LAN drivers, nothing seems to work.. Which doesnt make sense cus on the other PC it works fine and the WiFi hits higher speeds aswell.

I have fixed the issue after using google for the past almost 12hrs ^^
The issue was some command in the Command Prompt, ''netsh int tcp set global autotuninglevel=normal'' mine was disabled.

That is quite the download rate, somewhere around 50MB/s. Is the slower computer in question able to write to its drive that fast? If it is a spinning disk and is quite fragmented that might be a drive limitation. Does the other computer have an SSD?

As for WiFi, not all connections are created equal. If one computer is closer than the other it will have less dropped packets.

Not sure what you're talking about im talking about Internet speeds and you're talking about Disks and SSDs ^^

Yes, you have to have something as fast to receive a download. It can't cache everything incoming, it has to go somewhere.

A very common problem of people switching to very high bandwidth services finding out their hardware isn't fast enough to use all of it. That is why I wanted to know the hardware in both computers.

WiFi speeds are also misleading. Actual bandwidth is variable depending on the number of devices in the general area that are broadcasting. Which includes devices that aren't on your network. Sometimes choosing a channel on your router other than the default can make a huge difference. The farther the distance the more chances of interference and packet drops. 2.4Ghz WiFi is longer range but lower bandwidth then 5Ghz. 5Ghz has trouble going through more than a wall or two, but has the most bandwidth.

The PC with the good internet speed is actually the bad PC ^^ It has a normal HDD, worse MOBO, CPU and GPU. As the PC with the bad internet has an SSD. Im only talking about internet with the cable, dont rly mind the WiFi being slow as I only use it with my phone.

The PC with the bad inet has a i7 6700k, GTX 980ti, Asus Z170 Pro.
