I'm running into a weird problem where my internet speed changes depending on what apps I use. It shows up mostly when using browsers. I have a 1gb wired line and I can play games at steady 10-50 ping all the way through without any lag or stutter. But if I try to open a streaming app or even attach a small file like an email, it sometimes crashes right away. When I unplug my ethernet cable from the back of my computer and plug it back in, things work fine for a while before going back to being slow again. If I start watching something in that browser tab, I can watch it at 1080p all the way through until I close it. But if I refresh the page or close the window, it often won't come back up. I tried turning off the automatic speed adjustment feature but nothing stopped it from happening again. Someone please tell me what might be causing this? I've also swapped my ethernet cable to see if that fixed it, but I'm pretty sure this is something with my computer because other devices on the internet are working fine. I'm ready to give you more info or help out, so thanks for reading!

Here are a few things worth trying blindly: Set your DNS settings to 8.8.8.8 or 1.1.1.1 in the IPv4 options. Your computer might be using your router as a proxy, which can sometimes fail. Turn off IPv6 support on your PC because some programs only work with IPv4 while others need it turned off. If you have software pretending to be a "gamer" network or speeding up your internet for certain things, that's probably bloatware coming from your motherboard or graphics card. A common example is CFOSpeed, but there are many similar names. If you see anything like that, remove it immediately.

You can also use Task Manager, Resource Monitor, and Process explorer to check how well the computer is running. Use all three tools but only one at a time. Open the tool and just look at the system. What resources are being used? How much of them? What program is using any given resource? For example, bloatware like the one mentioned by @bill001g. Leave the viewing window open while you play games. Watch for what changes or disappears in the tool window. Also, if I follow these steps correctly, next open a stream and keep watching the tool window. There is a good chance you'll spot some change that matches the speed change. Process Explorer comes from Microsoft, it's free. https://learn.microsoft.com/en-us/sysint...s-explorer Take your time; don't rush things. Be careful and methodical. Don't expect quick results. Sometimes problems take a few minutes to show up.

Do you have 1 Gbs LAN or is that your internet speed? Can you tell me both and if you are wired on LAN? Any upload or download that causes buffer bloat can really slow things down for you. You need to make sure you get the speeds you pay for from your ISP. If you set something up wrong or use a wifi signal that isn't strong enough, you'll have to find out which one it is. Most consumer routers aren't good at fixing their own problems. iftop on your router shows traffic coming from all connections, but the other way around is hard to do. You can just make yourself the only client and look at your resource monitor. This will be easier to narrow down the problem app. I've seen people start a cloud backup and it takes weeks to run and they don't even notice until it's too late.
