How to get the ethernet working?

If you are facing issues connecting to the internet through your Ethernet cable, don’t worry, we’ve got you covered. Troubleshooting Ethernet connectivity problems can be frustrating, but with a systematic approach, you can get your Ethernet working in no time. In this article, we will provide you with a step-by-step guide to help you resolve Ethernet connectivity issues.

1. Check Physical Connections

The first and most crucial step is to ensure that your Ethernet cable is securely connected to both your computer and the router or modem. Make sure there are no loose connections or damaged cables that may affect the connection.

2. Restart Your Devices

Sometimes a simple restart can fix connectivity issues. Turn off your computer, router, and modem. After waiting for a few seconds, turn them back on in the following order: modem, router, and then your computer.

3. Update Network Drivers

Outdated or faulty network drivers can often be the root cause of Ethernet connection problems. Visit your computer manufacturer’s website and download the latest drivers for your network adapter.

4. Disable Wi-Fi

Sometimes, having both Wi-Fi and Ethernet enabled can create conflicts. Disable the Wi-Fi on your computer and check if the Ethernet connection works.

5. Disable Energy-Efficient Ethernet (EEE)

Some network adapters have Energy-Efficient Ethernet enabled by default, which can cause connectivity issues. Disable this feature by accessing your network adapter settings in the Device Manager.

6. Check Firewall and Antivirus Settings

Firewalls and antivirus programs can sometimes block or interfere with network connections. Temporarily disable these applications and check if you can establish an Ethernet connection.

7. **Check IP Settings**

An incorrect IP configuration can prevent your Ethernet from working. Open the Command Prompt (Windows) or Terminal (Mac), and type “ipconfig /renew” (Windows) or “sudo ipconfig set en0 DHCP” (Mac) to attempt to renew the IP address.

8. Flush DNS Cache

Flushing the DNS cache can help resolve connectivity issues. Open the Command Prompt (Windows) or Terminal (Mac) and type “ipconfig /flushdns” (Windows) or “sudo killall -HUP mDNSResponder” (Mac) to flush the DNS cache.

9. Check Router Configuration

Ensure your router is properly configured and supports Ethernet connections. Refer to the router’s manual or contact your Internet Service Provider for assistance.

10. Check for IP Address Conflict

If multiple devices on your network are using the same IP address, it can cause connection problems. Assign a static IP address to your computer or enable DHCP (Dynamic Host Configuration Protocol) on your router to automatically assign IP addresses.

11. Test with a Different Ethernet Cable

Sometimes, a faulty Ethernet cable can be the culprit. Try using a different Ethernet cable to troubleshoot the issue.

12. Contact Your Internet Service Provider

If all else fails, reach out to your Internet Service Provider for further assistance. They may be able to diagnose and resolve any network-related problems from their end.


Q1. Why is my Ethernet not working?

A1. There can be several reasons; however, it could be due to loose connections, faulty cables, outdated drivers, or network configuration issues.

Q2. How do I know if my Ethernet cable is faulty?

A2. Try using a different Ethernet cable and check if the issue persists. If the problem disappears, it indicates a faulty cable.

Q3. Should I use Wi-Fi or Ethernet?

A3. Ethernet generally provides a more stable and faster connection compared to Wi-Fi. If possible, it is recommended to use Ethernet for tasks that require high-speed internet.

Q4. Can a firewall or antivirus software block Ethernet?

A4. Yes, firewalls and antivirus programs may block Ethernet connections. Disable them temporarily to check if they are causing the issue.

Q5. How do I find my network adapter’s manufacturer?

A5. You can find your network adapter’s manufacturer by checking the Device Manager (Windows) or System Report (Mac).

Q6. What is EEE and how does it affect Ethernet?

A6. Energy-Efficient Ethernet (EEE) is a feature that reduces power consumption for network adapters. However, it can sometimes cause connectivity problems and should be disabled.

Q7. Can a faulty router prevent Ethernet connection?

A7. Yes, a faulty router can prevent Ethernet connections. Ensure your router is functioning properly and properly configured.

Q8. How do I assign a static IP address?

A8. You can assign a static IP address in the network settings of your computer. Consult your operating system’s documentation for specific instructions.

Q9. Should I contact my ISP if Ethernet is not working?

A9. If you have exhausted all troubleshooting steps, contacting your Internet Service Provider is recommended as they can assist with diagnosing and resolving network-related issues.

Q10. Are there any software tools to troubleshoot Ethernet connectivity?

A10. Yes, there are various network diagnostic tools available, such as ping, network analyzers, and driver updating tools, which can help identify and solve Ethernet connection issues.

Q11. How often should I update my network drivers?

A11. It is generally recommended to update your network drivers periodically, especially when experiencing connectivity issues or after a significant operating system update.

Q12. Can a faulty network card cause Ethernet problems?

A12. Yes, if your network card is faulty, it can cause Ethernet connection issues. Consider replacing the network card if other troubleshooting steps do not resolve the problem.

By following these troubleshooting steps, you should be able to get your Ethernet working once again. Remember to approach each step systematically, and if all else fails, reach out to your Internet Service Provider for further assistance. Stable and reliable Ethernet connectivity will ensure smooth internet browsing, online gaming, and efficient data transfers.
