Thanks to recent advancements in technology, most internet users can benefit from high-speed connections, making web browsing a very pleasant experience. It’s a well-known fact that data transfer speed is higher with LAN connections compared to Wi-Fi. However, sometimes users can also experience slow LAN speeds due to various issues: outdated drivers, particular browser settings, and so on.
Interestingly enough, many Windows 10 users complained about slow LAN speed issues shortly after they upgraded to Microsoft’s latest OS.
I recently upgraded my system from windows 8.1 to 10, then I faced a problem that although I was having a very fast internet connection but I was experiencing a very slow browsing & download. Please help…..
How to fix slow LAN speed issues on Window 10 PCs
Solution 1 – Check your hardware
Don’t forget to unplug your modem from time to time. Keeping it working for days on end may affect its performance. Also, use a different port: the one you’re currently using may be broken.
As a quick reminder, not all network cables are created equally. Actually, some cables may even slow down your internet connection. The best network cables to use are Cat–6 cables.
Solution 2 – Install the latest OS and driver updates
Make sure you’ve installed the latest Windows updates on your computer. Also, don’t forget to update your hardware drivers through Windows Update or by manually downloading the latest drivers from your hardware manufacturer’s website.
Solution 3 – Disable Windows Auto-Tuning Feature
- Launch Command Prompt by typing cmd in the search box.
- Type the following command: netsh interface tcp show global
- Now, look for the Receive Window Auto-Tuning Level feature. If it’s “normal”, disable it.
- To disable it, type the command netsh int tcp set global autotuninglevel=disabled
- Perform a test to see if this workaround solved the problem.
Solution 4 – Disable Large Send Offload (LSO)
- Go to the Device Manager and expand Network Adapters.
- Double-click on your Network Card and click on the Advanced tab.
- Select Large Send Offload V2 (IPv4) and set the value to Disabled
- Do the same for Large Send Offload V2 (IPv6).
- Click OK.
Solution 5 – Stop background apps
- Go to Start, type “background app”, and select Choose which apps can run in the background
- Toggle off all the apps you don’t want sending notifications or update while you’re not using them.
Solution 6 – Change your DNS settings
- Type Network and Sharing Center. Select the first result.
- Go to Change adapter settings, right-click the Ethernet network interface, and select Properties
- Select Internet Protocol Version 4 (TCP/IPv4) and go to Properties
- Select the “Use the following DNS server addresses” option and type your preferred and alternate DNS addresses.
You can use Google’s Public DNS addresses 188.8.131.52 and 184.108.40.206, OpenDNS addresses 220.127.116.11 and 18.104.22.168 or other DNS addresses. As a quick reminder, Google also offers the following IPv6 public DNS servers: 2001:4860:4860::8888 and 2001:4860:4860::8844.
Solution 7 – Install ad-blocking extensions
Regular ads, animations, and videos can sometimes use up a significant amount of your bandwidth. Try installing a dedicated an ad-blocking browser extension to block these bandwidth-hogging ads from reducing your bandwidth.
Solution 8 – Disable or uninstall your VPN
Most times, VPN programs slow down your internet connection. Try disabling your VPN and see if there’s any improvement.
Solution 9 – Refresh or reset your OS
Refreshing or resetting Windows can help you eliminate various issues that can slow down your connection. Refreshing your PC keeps your personal files and settings. Resetting it reinstalls Windows, but deletes your files, settings, and apps. For more information about the steps to follow to refresh or reset your OS, check out Microsoft’s Support page.
