How to Test Internet Speed on Windows 11/10

Testing your internet speed on Windows is quick and doesn't require any special software. Whether you're troubleshooting a slow connection or just curious about what you're getting from your ISP, this guide walks you through every method available on Windows 10 and Windows 11. Most tests take under 60 seconds.

The Fastest Method: Browser-Based Speed Tests

The easiest way to check your internet speed on any Windows PC is to open a browser and run a speed test directly. No downloads, no installs — just click and go.

How to Run a Browser Test

1. Open any browser (Chrome, Edge, Firefox, or Brave).
2. Go to Speedtest.now.
3. Click the "Start" button.
4. Wait about 15–30 seconds for results.

You'll get three key numbers: download speed (how fast data comes to you), upload speed (how fast data leaves your PC), and ping (the delay between your PC and the server, measured in milliseconds). If you're not sure what counts as a good result, check our guide on what is a good download speed.

Tips for Accurate Browser Results

• Close other tabs and apps that use the internet — streaming, downloads, cloud syncing, and Windows Update can all skew your numbers.
• Use a wired Ethernet connection if possible. Wi-Fi adds overhead and variability.
• Run the test 3 times and average the results. A single test can be thrown off by a momentary spike.
• Test at different times of day. Speeds during peak hours (7–11 PM) are often 10–30% lower than midday speeds.

Built-In Windows Methods (No Browser Needed)

Windows 10 and 11 have a few built-in tools that show network information. They won't give you a full speed test, but they're useful for quick checks.

Task Manager Network Tab

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Click the "Performance" tab.
3. Select "Ethernet" or "Wi-Fi" on the left panel.

This shows your real-time network usage — how much bandwidth your PC is currently using. It won't tell you your maximum speed, but it's great for spotting which app is eating your bandwidth. You'll see send and receive rates in Kbps or Mbps.

Network Adapter Properties

1. Open Settings → Network & Internet → Advanced network settings (Windows 11) or Settings → Network & Internet → Status → Change adapter options (Windows 10).
2. Click on your active connection.
3. Look for "Link speed" or "Speed" in the details.

This number shows your link speed — the maximum theoretical speed between your PC and your router, not your actual internet speed. For example, it might say 866 Mbps on Wi-Fi 5, but your real download speed could be 200 Mbps because your ISP plan caps at that.

PowerShell and Command Prompt

For a quick link-speed check via command line, open PowerShell and type:

Get-NetAdapter | Select-Object Name, LinkSpeed

This returns something like "Wi-Fi — 1.2 Gbps" or "Ethernet — 1 Gbps." Again, this is the connection to your router, not your internet speed. For a true speed measurement, you need to actually transfer data to an external server — which is what browser-based tests do.

Advanced: Speed Testing from the Command Line

If you prefer the terminal or want to automate speed tests, there's a free tool called Speedtest CLI from Ookla that runs directly in Command Prompt or PowerShell.

How to Install and Use Speedtest CLI

1. Download the Windows version from Ookla's Speedtest CLI page.
2. Extract the zip file to a folder (like C:\speedtest).
3. Open Command Prompt or PowerShell.
4. Navigate to that folder: cd C:\speedtest
5. Run: .\speedtest.exe

The output gives you download speed, upload speed, ping, jitter, and packet loss — all in your terminal window. This is handy for logging results over time. You could even set up a Windows Task Scheduler job to run it every hour and pipe results to a text file.

Understanding Your Speed Test Results

Numbers alone don't mean much unless you know what's good and what's bad. Here's a quick reference for common activities:
