Are you experiencing network issues or simply want to ensure that your Windows network connection is properly configured? A poorly optimized network setup can lead to slow file transfers, lag, and even limited internet performance—even if your internet speed is technically “fast.” In this guide, we’ll walk you through the correct way to set up and troubleshoot your network connection on Windows 10 and 11.
Why Network Configuration Matters
A common misconception is that your internet connection speed always reflects your actual experience online. In reality, many web servers throttle their own bandwidth. Moreover, the speed of your internal network—especially when transferring files or using shared drives—relies heavily on how your local connection is configured.
Most modern systems support gigabit Ethernet, yet many users unknowingly operate at reduced speeds due to misconfigured settings, faulty cables, or outdated network drivers.
Step-by-Step: Setting Up Your Network Properly
Step 1: Open Network Adapter Settings
- Click Start and type
Control Panel, then open it. - Navigate to Network and Internet > Network and Sharing Center.
- Click on Change adapter settings in the sidebar.
- Right-click your Ethernet connection and select Status. Note the speed.
If the speed is anything below 1.0 Gbps (i.e., 100 Mbps or 10 Mbps), you may be leaving performance on the table.
Step 2: Adjust Ethernet Speed & Duplex Settings
- Right-click the Ethernet adapter > Properties > Configure.
- Navigate to the Advanced tab.
- Scroll down to Speed & Duplex.
- Set it to Auto Negotiation.
If manually configured to 10 or 100 Mbps, your network will be throttled at that speed regardless of your internet plan.
Note: After changes, your network connection will temporarily disconnect and reconnect.
Step 3: Replace Faulty Hardware If Needed
If setting “Auto Negotiation” doesn’t restore gigabit speeds:
- Try another Ethernet cable – a damaged or low-quality cable can reduce speed.
- Check your switch/router – some budget devices only support up to 100 Mbps.
- Update network drivers – outdated drivers can prevent proper negotiation.
Improve Network Responsiveness: Change Your DNS Settings
Default DNS servers provided by your ISP are often slow and congested. Switching to a third-party DNS can improve browsing speed and reliability.
How to Change DNS in Windows:
- Go to Control Panel > Network and Sharing Center.
- Click Change adapter settings.
- Right-click your connection > Properties.
- Select Internet Protocol Version 4 (TCP/IPv4) > Properties.
- Choose “Use the following DNS server addresses” and enter:
Cloudflare DNS:
- Preferred:
1.1.1.1 - Alternate:
1.0.0.1
Google DNS (alternative option):
- Preferred:
8.8.8.8 - Alternate:
8.8.4.4
Click OK to apply.

Disable IPv6 for Simplicity
IPv6 offers many technical advantages, but for local home networks with under 255 devices, it’s generally unnecessary and can complicate troubleshooting.
To disable IPv6:
- Go to Network Adapter Properties.
- Uncheck Internet Protocol Version 6 (TCP/IPv6).
- Click OK.
Check for Network-Hogging Background Apps
Apps like Steam, Epic Games Launcher, Rockstar Launcher, and even Windows Update can silently use bandwidth. Here’s how to identify and control them:
Disable Startup Apps:
- Press
Ctrl + Shift + Escto open Task Manager. - Go to the Startup tab.
- Right-click apps you don’t need at startup and disable them.
Limit Windows Update Bandwidth:
- Open Settings > Windows Update > Advanced Options.
- Select Delivery Optimization > Advanced Options.
- Enable Limit how much bandwidth is used, and set a maximum (e.g., 1 Mbps) for background updates.
You can also view bandwidth usage under Activity Monitor in the Delivery Optimization panel.
Conclusion
A properly configured network is crucial for both local file transfers and reliable internet usage. While internet speed is determined by your ISP, your internal setup plays a major role in your overall experience.
From using quality cables to setting the correct speed and updating your DNS servers, small adjustments can bring big improvements. Don’t underestimate the impact of what’s running in the background either—monitoring and controlling app behavior can free up significant bandwidth.
