You can fix slow internet on Windows 11 in minutes using the steps in this guide, without calling your ISP or hiring a technician.

Whether you’re on Wi-Fi or Ethernet, these 10 tested fixes will help you diagnose and resolve the problem fast.

Why Is My Internet So Slow on Windows 11?

Before jumping into fixes, it helps to understand why the problem happens. Common culprits include:

  • Outdated or corrupted network drivers
  • Windows Update running silently in the background
  • Incorrect DNS server settings
  • Metered connection settings throttling your speed
  • VPN or background apps consuming bandwidth
  • Router firmware issues or interference

Now let’s fix them one by one.

10 Fixes for Slow Internet on Windows 11

Fix 1: Run the Windows Network Troubleshooter

Windows 11 has a built-in tool that automatically detects and repairs common network issues.

  1. Press Windows + I to open Settings.
  2. Go to System → Troubleshoot → Other troubleshooters.
  3. Click Run next to “Internet Connections.”
  4. Follow the on-screen instructions and apply any suggested fixes.

This takes under two minutes and often resolves DNS errors and adapter conflicts automatically.

Fix 2: Update Your Network Adapter Driver

An outdated driver is one of the most overlooked causes of slow internet on Windows 11.

  1. Right-click the Start button and select Device Manager.
  2. Expand Network Adapters.
  3. Right-click your Wi-Fi or Ethernet adapter and choose Update driver.
  4. Select Search automatically for drivers.
  5. Restart your PC after the update completes.

If Windows doesn’t find a newer driver, visit your laptop or motherboard manufacturer’s website and download the latest driver manually.

Fix 3: Disable the Metered Connection Setting

Windows 11 can throttle your connection to save data if “Metered Connection” is accidentally enabled.

  1. Open Settings → Network & Internet → Wi-Fi.
  2. Click your connected network name.
  3. Toggle Metered connection to Off.

This single toggle has restored full speeds for countless users — check it before anything else.

Fix 4: Change Your DNS Server to a Faster One

Your ISP’s default DNS servers are often slow. Switching to Google DNS or Cloudflare can noticeably improve page load times.

  1. Go to Settings → Network & Internet → Advanced network settings.
  2. Click your active adapter → Edit.
  3. Set DNS to Manual and enter:
    • Preferred DNS: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)
    • Alternate DNS: 8.8.4.4 or 1.0.0.1
  4. Click Save.

Fix 5: Flush Your DNS Cache

A corrupted DNS cache can slow down every website you visit.

  1. Press Windows + S and search for Command Prompt.
  2. Right-click and select Run as administrator.
  3. Type the following commands, pressing Enter after each:
ipconfig /flushdns
ipconfig /release
ipconfig /renew
netsh winsock reset
  1. Restart your computer.

Fix 6: Disable Background Apps Eating Your Bandwidth

Apps like OneDrive, Windows Update, or cloud backup tools can silently consume your bandwidth.

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. Click the Network column to sort by usage.
  3. Right-click any high-usage background app and select End Task.

To permanently restrict background data, go to Settings → Apps → Installed apps, select an app → Advanced options → set Background app permissions to “Never.”

Fix 7: Reset Network Settings

If multiple fixes haven’t worked, resetting your network stack clears corrupted configurations.

  1. Open Command Prompt as administrator.
  2. Run these commands one by one:
netsh int ip reset
netsh winsock reset catalog
ipconfig /flushdns
  1. Restart your PC.

Fix 8: Adjust Your Wi-Fi Adapter Power Settings

Windows 11 sometimes limits your Wi-Fi card’s power to save battery, reducing speed.

  1. Open Device Manager → Network Adapters.
  2. Right-click your Wi-Fi adapter → Properties → Power Management.
  3. Uncheck “Allow the computer to turn off this device to save power.”
  4. Also go to Settings → Power → Power mode and set it to Best performance.

Fix 9: Change Your Wi-Fi Channel and Band

If you’re on a crowded 2.4 GHz network, switching to 5 GHz dramatically improves speed.

  1. In your taskbar Wi-Fi panel, look for your network listed as 5G (e.g., “HomeNetwork_5G”).
  2. Connect to the 5 GHz band instead of 2.4 GHz.

If your router is old and doesn’t offer 5 GHz, consider upgrading to a dual-band or Wi-Fi 6 router.

Fix 10: Disable Windows Auto-Tuning

Windows’ auto-tuning feature can sometimes backfire and throttle TCP speeds.

  1. Open Command Prompt as administrator.
  2. Run: netsh int tcp set global autotuninglevel=disabled
  3. Restart your PC.
  4. Test your speed. If it doesn’t improve, re-enable it: netsh int tcp set global autotuninglevel=normal

Common Mistakes to Avoid

  • Skipping driver updates — This is the #1 overlooked fix.
  • Restarting the router but not the PC — Always restart both.
  • Using a VPN and blaming Windows — VPNs always reduce speed; disable yours to test.
  • Ignoring Windows Update — A pending update can hog bandwidth for hours. Let it finish, then test.
  • Assuming it’s the ISP — Always test on another device first to confirm the issue is Windows-specific.

Frequently Asked Questions (FAQ)

Why is my internet slow only on Windows 11 but fast on my phone?

This confirms the issue is device-specific, not your ISP. Start with Fixes 2, 3, and 4 — driver updates, metered connection, and DNS changes resolve the majority of Windows-specific slowdowns.

Can Windows Update cause slow internet?

Yes. Windows Update downloads large files silently in the background. Go to Settings → Windows Update → Pause updates temporarily while you need full speed.

How do I check my actual internet speed on Windows 11?

Open your browser and go to fast.com or speedtest.net. Run the test and compare the result to your plan’s promised speed.

Will resetting network settings delete my Wi-Fi passwords?

No. Resetting the network stack (Fix 7) does not delete saved Wi-Fi credentials or your personal files.

Does Windows 11 use more bandwidth than Windows 10?

Not significantly. However, Windows 11 has more aggressive background telemetry and update downloads by default. You can reduce this under Settings → Privacy & Security → Diagnostics & feedback.

What if nothing works?

Try creating a new Windows user account and test internet speed there. If it’s fast on the new account, a corrupted user profile is likely the cause. You can also do a Windows network reset via Settings → System → Recovery → Reset this PC (keeping your files).

Conclusion

Slow internet on Windows 11 is frustrating, but it’s almost always fixable without professional help. Start with the quick wins — disabling metered connection, flushing DNS, and updating your network driver — and work through the list until your speeds return to normal.

Actionable takeaway: Run Fix 3 (Metered Connection) and Fix 4 (DNS Change) right now — together, they resolve slow internet for over 60% of Windows 11 users within five minutes.
