Optimizing network performance in Windows can greatly enhance your online experience, whether you’re streaming, gaming, working remotely, or simply browsing. Network performance tuning involves adjusting system settings to improve speed, reduce latency, and ensure reliable connections. This guide walks you through 15 practical, proven methods to tune your Windows network settings. Each section provides clear, actionable steps, with tips for both beginners and advanced users.
Beginner Methods: Easy Wins for Immediate Results
1. Run the Windows Network Troubleshooter
Windows has a built-in tool to diagnose and fix common network problems.
Steps:
– Right-click the network icon in the system tray.
– Select Troubleshoot problems.
– Follow the prompts and apply any suggested fixes.
2. Update Your Network Adapter Drivers
Outdated drivers can cause slow or unreliable connections.
Steps:
– Press Windows + X and choose Device Manager.
– Expand the Network adapters section.
– Right-click your adapter and select Update driver.
– Choose Search automatically for updated driver software.
3. Use Wired Connections When Possible
Ethernet offers more stable and faster connections than Wi-Fi.
Tip: If your device allows, connect via a network cable instead of Wi-Fi, especially for gaming or video calls.
4. Disable Unnecessary Startup Programs (With Glary Utilities)
Background applications can consume bandwidth.
Steps with Glary Utilities:
– Launch Glary Utilities.
– Go to the Startup Manager.
– Disable unnecessary applications from starting with Windows.
Benefit: Frees up system and network resources, improving overall performance.
5. Optimize Power Settings for Maximum Performance
Some power plans throttle network performance to save energy.
Steps:
– Open Control Panel and navigate to Power Options.
– Select High performance.
– For laptops: Plug in your device when expecting heavy network use.

6. Adjust Receive Side Scaling (RSS) and Interrupt Moderation
RSS and Interrupt Moderation help distribute network processing across multiple CPU cores.
Steps:
– Open Device Manager.
– Right-click your network adapter, select Properties.
– Go to the Advanced tab.
– Set Receive Side Scaling to Enabled.
– Set Interrupt Moderation to Enabled.
7. Disable Large Send Offload (LSO) if Experiencing Latency
While LSO can improve throughput, it may cause latency in some cases.
Steps:
– In your network adapter’s Advanced settings, find Large Send Offload v2 (IPv4 and IPv6).
– Set both to Disabled.
– Click OK and restart your PC.
8. Increase DNS Resolution Speed
Using a faster DNS server can reduce delays when accessing websites.
Steps:
– Open Control Panel > Network and Sharing Center > Change adapter settings.
– Right-click your connection > Properties.
– Select Internet Protocol Version 4 (TCP/IPv4) > Properties.
– Set Preferred DNS server to 8.8.8.8 and Alternate DNS server to 8.8.4.4 (Google DNS) or another fast provider.
9. Clear Network Cache and Temporary Files (With Glary Utilities)
Old DNS and temporary files can slow connections.
Steps with Glary Utilities:
– Open Glary Utilities.
– Use the 1-Click Maintenance feature to clean DNS cache, temp files, and more.
10. Disable Windows Auto-Tuning
Windows auto-tuning can sometimes interfere with specific network setups.
Steps:
– Open Command Prompt as administrator.
– Type: netsh int tcp set global autotuninglevel=disabled
– Press Enter.
– To check status: netsh int tcp show global

11. Optimize TCP/IP Parameters via Registry Editing
Editing the Windows Registry can further enhance network throughput and reduce latency.
Caution: Always back up your registry before making changes.
Steps:
– Press Windows + R, type regedit, and press Enter.
– Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
– Add or adjust these DWORD values:
TcpAckFrequency = 1 (lowers latency for gaming)
TCPNoDelay = 1 (enables Nagle’s Algorithm)
– Restart your PC.
12. Enable Jumbo Frames (For Gigabit Networks)
Jumbo frames can improve throughput on local networks.
Steps:
– Go to Device Manager > Network adapter > Properties > Advanced.
– Find Jumbo Packet or Jumbo Frames.
– Set to the highest value supported (usually 9000 bytes).
(Note: All network devices must support jumbo frames.)
13. Set QoS (Quality of Service) for Priority Traffic
Prioritize network traffic for specific apps or services.
Steps:
– Open Group Policy Editor (gpedit.msc).
– Navigate to Computer Configuration > Windows Settings > Policy-based QoS.
– Create a new policy to prioritize specific traffic (e.g., VoIP, streaming).
14. Update Router Firmware and Optimize Router Settings
Performance bottlenecks can originate outside your PC.
Steps:
– Log into your router’s admin page.
– Update firmware if available.
– Enable features like Quality of Service (QoS) and select optimal Wi-Fi channels.
15. Monitor Network Traffic and Usage (With Glary Utilities)
Identifying bandwidth-hogging apps helps you tune performance.
Steps with Glary Utilities:
– Open Glary Utilities.
– Use the Network Monitor tool to view real-time bandwidth usage.
– Identify and manage resource-heavy applications.
Conclusion
Tuning Windows for optimal network performance involves a mix of simple tweaks and more advanced configuration changes. Regularly updating drivers, managing background programs, adjusting system and adapter settings, and leveraging comprehensive tools like Glary Utilities can dramatically improve your network experience. Beginners are encouraged to start with basic steps, while advanced users can fine-tune settings for specialized scenarios like gaming or large file transfers. With these 15 methods, you’ll be well-equipped to make the most of your Windows network connection.
