Internet connection is slow, but speed tests are quick. Using Ethernet provides a reliable boost.
My computer uses Ethernet (CAT 6) with speeds around 600 Mbps download and 400 Mbps upload. Yet the real internet performance is very slow. YouTube videos often fail to play smoothly, and refreshing a page like Twitter takes a long time. The speed test results from fast.com show a significant drop, but the issue seems tied to actual usage rather than just the test. When watching an unbuffered video, the connection barely reaches 1 Mbps in Task Manager. The spike you see on the graph matches the test timing, but the screenshot taken while watching a video showed poor quality and constant buffering. My PC specs include an Intel i5-9400f, 16GB RAM, a 2x GTX 1050 Ti GPU, and an Asus TUF H370-PRO motherboard. The BIOS version is 1402, running Windows 10 Pro 1903. Additional help would be useful.
Your information passes through various routers, switches, and servers before reaching Youtube. For optimal performance, all connections need to operate at high speed. In certain scenarios, specific fiber links between locations may become congested, causing delays in your traffic. During a speed test, you're essentially sending or receiving files with random data, transmitting them to a server located close to you—perhaps within a short distance. With Youtube or similar platforms, the path might involve many devices between you and the site, or your data could travel across oceans to a distant datacenter, where overloaded cables transmit packets from numerous sources. You can use Visual Traceroute at https://sourceforge.net/projects/openvisualtrace/ to observe how your data moves globally. Additionally, Youtube might intentionally restrict uploads—such as capping speeds at 100 Mbps or 300 Mbps—to manage network load. Many servers connected to the internet use high-speed cards (10G, 25G, or 40G) and handle simultaneous uploads from numerous users. For instance, if 30 people upload videos to a device with a 10G connection, the total bandwidth (up to 10,000 Mbps) is divided among them, resulting in varying speeds depending on time, server location, and other network activities.
Thanks for the guidance. I’ll check out the Visual Traceroute tool, but it seems the issue can be tough to resolve. Other options like Google, Twitter, or TradingView might work better, especially with a stable Wi-Fi connection.
Use a different browser for testing. Avoid extensions or anything that might slow performance.
Hi, I'm facing the same issue after a Windows 10 update. My speed tests on fast.com and Speedtest show 60 Mbps download, but the launchers I use—Steam, Rockstar, Epic—report 8 Mbps. This happens in all browsers I have. Microsoft has told me it's an ISP problem, but how can I explain that the speed in these apps matches what my internet actually provides? I've checked forums and found no solution, just suggestions like changing DNS or using Google DNS. My PC has a Ryzen or Intel 1GB Ethernet card, runs Windows 10 with the latest updates, and cable 5E 1.5m with 16GB RAM. It works on Edge, Chrome, and Firefox. I've tried downloading from various servers (MS, Google Drive, MediaFire, etc.) but they only reach 1.3 Mbps or lower. If I download from three different servers at once, the combined speed is higher, but each file still lags. The issue seems to persist even after reinstalling drivers or changing DNS. I've also noticed the speed drops significantly when using different networks, but I can still download multiple files simultaneously. I'm hoping someone can help without just repeating the fixes I've already tried. Thanks!
Search for a big file to test download speed (the Ubuntu Full ISO works well). If you experience fast downloads but slow browsing, the problem may lie with the browser or its ads. Consider checking for ad-blockers, antivirus interference, high CPU usage (keep it under 10% in Task Manager), router limitations during speed tests, or interference from a VPN. Also, ensure you're using a 5GHz network instead of 2.4GHz for better performance. You can run a ping to google.com from the command prompt to see if internet speed is affected.
i've tried various methods to download and upload videos from my google drive. the upload works fine, but downloading consistently lags around 1.3mb/s. antivirus win defender is off, cpu usage stays under 10%, no vpn active, wifi disabled. the issue seems to persist across browsers—edge, chrome, firefox, opera, iexplorer—and even with a different modem/router it still doesn't improve. i suspect the problem might be related to the network connection or firewall settings. i considered reinstalling windows, but it seems the same issue persists on both devices. let me know if you have any suggestions.
Do you have another machine you can run tests on the same network? If not, perhaps ask a friend with a laptop to join you. If you notice identical results on another device, the problem likely lies with your ISP, modem, or router. If the other unit works, you probably have a software-related issue. I recommend updating drivers and firmware—not just for network gear, but also install the newest BIOS, video, and chipset updates. Good luck!
