A network faulty such as Ethernet not working can disrupt your work, gaming, or streaming. However, many of these common problems can be fixed with some straightforward troubleshooting. In this article, we’ll explore what might be causing your Ethernet issues and give you a step-by-step guide to fix it.
What Is Ethernet?
Before exploring why Ethernet doesn’t work, you need to understand what Ethernet is. Ethernet uses a cable to connect your computer or device directly to a modem or router. It provides a stable and fast Internet connection. Unlike Wi-Fi, which can be affected by distance and obstacles, Ethernet is generally more reliable and faster.
Ethernet Not Working? – Common Causes
Several factors can lead to an Ethernet connection not working. Common causes include:
Ethernet Cable Problems: Verify if your Ethernet cable is damaged or not plugged in. Take a moment to check for any wear and tear. If you suspect it’s faulty, try using a different Ethernet cable to see if that solves the problem. Moreover, make sure the cable is securely connected. Because a loose connection can lead to your Ethernet not working.
Port Issues: Ethernet port on your device or router isn’t working right will also cause problems. Try plugging the cable into a different port or device.
Network Configuration Problems: Incorrect settings can prevent your device from connecting to the network. Ensure your network adapter is enabled and the settings are on auto.
Driver Issues: Outdated or broken network drivers can lead to Ethernet working problems. To ensure everything is up to date, check for updates to your network drivers in your device settings.
Router or Modem Glitches: Sometimes your router or modem needs a restart or firmware update. As the router and modem work for a long time and are overheating, they will influence your Ethernet to work properly.

How to Fix Ethernet Not Working?
An Ethernet connection offers a fast internet connection for gaming, streaming, and working. Another internet technology is Wi-Fi which is often used in our daily life. Is Ethernet faster than Wi-Fi? Generally, the answer is yes. Because the Wi-Fi signal is restricted by distance and can easily be influenced by physical things. However, sometimes Ethernet not working but Wi-Fi is. Here we provide some ways to fix this problem quickly.
Check Physical Connection
The first step in troubleshooting why your Ethernet not working is to check all physical connections. Ensure your cable is securely connected to your device and the router or modem. Check the cable for any visible signs of wear and tear, such as fraying or cuts. If you find any damage, consider replacing the cable.
Test Other Devices
Try plugging the same Ethernet cable into another device, like a laptop. If your connection is correct, the problem might be with your Ethernet cable.
Test the Ethernet Cable
To determine if the cable is the problem, you can try a different cable and swap it out to see if the connection works. If your router or modem has multiple Ethernet ports, connect your cable to a different port to see if that resolves the issue.
Restart Your Router and Modem
Turn off your devices experiencing issues. Unplug the power cords from both your modem and router. Wait for about 30 seconds, then plug them back in. You’d better wait until all lights are stable before turning your device back on.
Disable Firewall or Security Software
Sometimes firewalls or security software can block your connection. Try temporarily disabling them. If this improves your network connection, you might need to adjust the settings so they don’t interfere with your Ethernet.

Ensure Ethernet Is Enabled
The steps to verify that you have turned on Ethernet are as follows:
- Press Windows+R to open the run box.
- Type ncpa.cpl and click OK. This will open the Network Connections window.
- Look for your Ethernet connection, then right-click on it.
- Select “Status” to check if it is enabled. If not, right-click on the connection again and choose the “Enable” button.
Reset Network Settings

On a Mac, you can delete your Ethernet connection by going to “System Settings” > “Network,” selecting it, and clicking the minus (-) button. Then, add a new Ethernet connection by clicking the plus (+) button.
Update Network Drivers
Outdated or corrupted network drivers can lead to connectivity issues. Therefore, you need to update the drivers to ensure a stable network connection. For Windows users, right-click the “Start” menu, select “Device Manager”, and find “Network adapters”. Click your Ethernet adapter, and choose “Update driver”. This helps ensure everything is up to date.

Checking for Network Issues
If you’ve tried these troubleshooting steps and your Ethernet is still not working, you can check for further network issues:
Check Your ISP’s Website: Look for any service outage announcements that could be affecting your area.
Run a Network and Internet Troubleshooter: Use your device’s built-in Network and Internet diagnostic tools to check for Ethernet not working issues.
- Right-click the Start button and select “Settings”.
- Navigate to the “System” tab and open the “Troubleshoot” settings.
- From there, go to “Other Troubleshooters”.
- Choose “Network and Internet”, then click “Run” next to it.
