Single Computer gets terrible internet speed.

Promised 15/3 internet speed. Router shows 7/3. A single computer only gets 0.1/1, while XBOX and iPhone gets 5+/3. I am connected to my router via Ethernet, and updated my Realtek Network Adapter Drivers, and do not have AMD Quick Stream.
Update: I left my computer and XBOX downloading the same game update overnight, when I woke up, the XBOX was full speed ahead at 6 mbps, while my computer lagged behind at 100 kbps, and even down to bytes per second in the worst times. Both have highest priority under the router settings.

  1. Try a different cable to the slow pc and a different port on the router.

    Already tried that. My computer also gets the terrible intrernet speed over WiFi, too.

  3. OK, so you know it's not a WiFi issue, & it's not the cable or router port, nor a driver issue.

    Did this just start happening recently? If so, try to isolate if there were any software/hardware changes that happened that day -- even if they seem unrelated -- & see if you can rollback to before the changes.

    Also, have you tried rebooting into Safe Mode with Networking -- not sure what it's called in Windows 10, but that was the name for it in Windows 7. Basically, it lets you access the Internet, but just about every application/driver not 100% necessary for running Windows is left turned off. If your speed goes up in this mode, it means there's an application that runs on your PC that's causing the slowdown. Sometimes malware/viruses can do that, & sometimes AV applications can cause that as well.

    Finally, see if you can take the PC to a friend's house (or better yet, if it's a laptop take it to a place with free WiFi -- Starbucks, Wendy's, local library, etc.) & test it there.

    If the speed issue is still there, it's probably a hardware issue on the PC. New Ethernet adapters are fairly inexpensive (maybe $20-50USD tops), & should fix any hardware issue you might be having. If your current Ethernet port is built into the motherboard, I would recommend keeping an eye out for any other problems (just in case you're looking at a failing motherboard).

    If the speed issue goes away, then there's something going on with your router. To make sure it's not a settings issue, do a full reset on the router (make sure you write down somewhere the current SSID/password & other settings for the WiFi so you can set them again), leave everything but the PC disconnected from the router, & test again. If the speed problem goes away, then you're good. If it's still there, it's probably a hardware problem with the router, & you'll need a new one.

    I'll try all of these.

    Alright, I booted in Safe Mode with Networking, and tested downloads on various applications. Surprisingly, the speed definitely increased up to 1.5+ mbps, but how do I isolate the program that's leeching all the network? Using task manager under the "Network" sorter yields no results..
