How to Fix Slow Internet on Windows: Complete Guide

Nothing is more frustrating than a slow internet connection. Before blaming your ISP, try these Windows-specific fixes that often solve the problem.

Quick Diagnosis

Test Your Speed

Rule Out the Obvious

  • Restart your router
  • Try a different device
  • Check for outages with your ISP
  • Windows-Specific Fixes

    1. Reset Network Settings

    Sometimes network configuration gets corrupted:

    netsh winsock reset
    netsh int ip reset
    ipconfig /release
    ipconfig /renew
    ipconfig /flushdns

    Restart after running these commands.

    2. Disable Metered Connection

    Windows might be limiting your connection:

  • Settings → Network & internet → Wi-Fi
  • Click your network → Turn off "Metered connection"
  • 3. Update Network Drivers

    Outdated drivers cause many issues:

  • Device Manager → Network adapters
  • Right-click your adapter → Update driver
  • Search automatically for drivers
  • 4. Disable Windows Auto-Tuning

    Sometimes helps with certain routers:

    netsh int tcp set global autotuninglevel=disabled

    5. Change DNS Servers

    Use faster DNS servers:

  • Settings → Network & internet → Wi-Fi → Hardware properties
  • Edit DNS settings
  • Use 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)
  • Advanced Solutions

    Disable Background Apps

    Many apps consume bandwidth silently:

  • Settings → Apps → Startup → Disable unnecessary apps
  • Check Task Manager → Network tab for bandwidth hogs
  • Disable Delivery Optimization

    Windows shares updates with other PCs by default:

  • Settings → Windows Update → Advanced options
  • Delivery Optimization → Turn off
  • Check for Malware

    Malware can consume bandwidth. Run a full Windows Security scan.

    Hardware Considerations

  • Use Ethernet instead of Wi-Fi when possible
  • Position router centrally
  • Consider a mesh Wi-Fi system
  • Upgrade to Wi-Fi 6 router
  • Conclusion

    Slow internet usually has a fixable cause. Work through these solutions systematically, and you'll likely find significant improvement.
