How to Fix Ethernet Spiking on Windows 11: A Comprehensive Guide
Experiencing unexpected Ethernet spikes in your Windows 11 Task Manager? These sudden surges in network activity can disrupt your online activities and significantly affect performance. This guide provides a step-by-step approach to identifying common causes of Ethernet spiking, including issues related to background applications, network settings, and outdated drivers. By following the outlined solutions, you’ll learn how to optimize your network performance effectively and restore stability to your internet connection.
Step 1: Update Your Network Drivers
Keeping your network drivers up to date is essential for maintaining optimal network performance. Outdated drivers can lead to inefficiencies and compatibility issues that may cause Ethernet spikes. To update your network drivers:
- Press Windows + X and select Device Manager.
- Expand the Network adapters section.
- Right-click on your Ethernet adapter and select Update driver.
- Choose Search automatically for updated driver software and follow the instructions provided.
Ensure you restart your computer after the update to apply the changes effectively.
Step 2: Change to Google DNS
Changing your DNS settings to Google’s public DNS can help enhance your network stability and decrease spike occurrences. To switch to Google DNS, follow these steps:
- Open the Control Panel and go to Network and Internet.
- Select Network and Sharing Center, then click on the connection type (e.g., Ethernet).
- Click Properties and highlight Internet Protocol Version 4 (TCP/IPv4), then click Properties again.
- Select Use the following DNS server addresses and enter:
- Preferred DNS server:
8.8.8.8 - Alternate DNS server:
8.8.4.4
Step 3: Select the WPA2-PSK AES Protocol
Configuring your wireless network to use the WPA2-PSK with AES encryption enhances security while also improving performance. To ensure your network uses this protocol:
- Access your router’s settings page (typically
192.168.1.1or192.168.0.1). - Navigate to the Wireless Settings section.
- Look for the Security settings and select WPA2-PSK with AES encryption.
- Save changes and reboot your router if prompted.
Step 4: Close Bandwidth Hogging Background Programs
Programs running in the background that consume large amounts of bandwidth can cause noticeable spikes in your network activity. To identify and close these applications:
- Open the Task Manager by pressing Ctrl + Shift + Esc.
- Go to the Processes tab and look for applications that are using high network resources.
- Right-click on these applications and select End task to close them.
Consider uninstalling or disabling programs that frequently consume excessive bandwidth if needed.
Step 5: Reset Network Settings Using Command Prompt
Resetting your network settings can resolve issues that lead to Ethernet spiking. Here’s how to do it:
- Press Windows + S and type
cmd. - Right-click on Command Prompt and select Run as administrator.
- Type the following commands and press Enter after each one:
netsh int ip resetnetsh winsock resetipconfig /releaseipconfig /renewipconfig /flushdns
Extra Tips & Common Issues
While following these steps, it’s important to keep these additional tips in mind:
- Regularly check for malware using trusted antivirus software, as malicious software can also cause network issues.
- Consider monitoring your network with tools to identify which devices are consuming the most bandwidth.
- If performance issues persist after trying these solutions, it could indicate hardware problems, such as a faulty network card or router.
If you face any difficulties implementing these solutions or notice persisting issues, consulting your service provider might provide additional insights specific to your connection.
Frequently Asked Questions
Why does my Ethernet spike only at certain times?
Often, this can be attributed to network congestion during peak usage times, where multiple devices are accessing bandwidth simultaneously.
Can I use third-party DNS services instead of Google?
Yes, there are several alternatives like Cloudflare (1.1.1.1) and OpenDNS, which you can consider based on your needs.
What if resetting my network settings doesn’t help?
If the reset doesn’t yield improvements, further investigation may be needed. This could include checking physical connections, ensuring no interference, or even replacing hardware components.
