How To Do If Ethernet Not Working But Wi-Fi Is? [3-Sec FIX]

Connecting your device, such as a computer or smart TV, to the internet offers two main options: via a cable (Ethernet) or wirelessly (WiFi). Both methods are reliable, but what if your wired connection (Ethernet) encounters issues while your wireless connection (WiFi) remains functional?

To address this situation, ensure your Ethernet cable is securely connected to a functional Ethernet port on your router or PC. Many routers or modems have multiple Ethernet ports, and some might be in better condition than others. Select a functioning port for your connection. In this article, we will explore troubleshooting steps for rectifying Ethernet connection problems. There could be various factors affecting your Ethernet connection. However, let’s first briefly cover the most common issue encountered in Ethernet connections:

Possible Causes Potential Fixes

  • Ethernet driver files might not be properly loaded. – Restart the PC or relevant device.
  • Virus-related issue could be at play. – Perform a thorough Anti-Virus scan on your PC.
  • Outdated driver could be causing the problem. – Update drivers online to the latest versions.
  • Damaged wires might be disrupting the connection. – Repair or replace the damaged Ethernet cable.
  • A faulty port on your router could be a factor. – Switch to a functional port on your router.
  • The Ethernet port on your device might be faulty. – Utilize Network adapters to address the issue.

By applying these solutions, you can troubleshoot and potentially resolve issues with your Ethernet connection, ensuring seamless internet connectivity for your device.

Restart Your PC

Restarting your PC can often resolve corrupted files and fix the issue. Follow these simple steps:


  1. Press “Alt + F4,” and a dialogue box will appear.
  2. Use the down arrow key to highlight “Restart” on the bottom right of the keyboard.
  3. Press “Enter” on the keyboard.
  4. Allow your PC to restart and check if this resolves the problem. If not, proceed to the next troubleshooting step.

Quick Virus Scan

A virus might be causing the issue. Use anti-virus software to scan and prevent any potential virus.

  • Windows Defender is recommended as a reliable option. Start a virus scan by going to settings and initiating the scan.
  • Regularly update your anti-virus software to stay current and effectively combat viruses.

Update Windows and Windows Defender

Keep your system updated by typing “Check for Updates” in the Windows search bar. This ensures the latest security patches and improvements.

Windows Troubleshooter

If the connection problem is isolated to your PC and not the router or internet service provider, use the Windows troubleshooter to address the issue.

  1. Press Windows + I buttons simultaneously to launch Settings.
  2. Open the “Update & Security” section.
  3. Choose the Troubleshoot option from the left-hand list.
  4. Select “Internet Connection Troubleshooter” and run it.
  5. Wait for the troubleshooting process to complete, then attempt to resolve the Wi-Fi connection problem.

Ethernet Driver

Drivers enable proper hardware recognition and functioning. Incorrectly installed or corrupted drivers could be the cause. Reinstall or update Ethernet drivers with these steps:

  1. Press the Windows key and type “Device Manager,” then press Enter.
  2. Locate “Network adapters” and double-click to expand the list.
  3. Find “Ethernet” and double-click on it.
  4. In the small window, click on the “Driver” tab.
  5. Press “Update Driver” and choose “Browse from the internet.” Let the process complete.
  6. If the Ethernet issue persists, proceed to the next step.

Following these steps can help diagnose and potentially resolve Ethernet connection issues on your PC.

Damaged LAN Wire

A malfunctioning LAN wire could be the root cause, with potential issues in the LAN connector or physical wire damage. A visual examination of the wire, including the RJ-45 connectors, can reveal signs of tearing or stretching.

  • If any connectors appear damaged or compromised, consider replacing the cable or repairing it.

Router’s Ethernet Port

An alternative possibility is a faulty Ethernet port on your router.

  • Most routers possess multiple Ethernet ports. Troubleshoot by connecting the wire to a different port on the router’s rear. Refer to another article on router fixes for further guidance.

Device’s Ethernet Port

A potentially faulty Ethernet port on your device (e.g., PC, smart TV) is another consideration. A simple visual inspection can help determine its condition.

  • If the port appears undamaged, explore alternative methods to establish internet connectivity.
  • For smart TVs, leverage built-in WiFi support.
  • PCs lacking WiFi support can benefit from WiFi adapters, cost-effective solutions available from online stores or computer hardware retailers.
  • While USB-to-Ethernet adapters are available, they might not deliver the ISP-offered speed and consistency.
  • Superior USB-to-Ethernet adapters exist, providing better speed and reliability, albeit at a higher cost.

Incorporating these measures, you can effectively address potential issues stemming from damaged LAN wires, router ports, or device Ethernet ports, ensuring uninterrupted and efficient internet connectivity.

Wrapping it up

Internet connectivity is a fundamental necessity for devices like computers and smart TVs. In essence, there are two primary methods to establish this connection: through a wired setup or a wireless network.

Issues can arise due to damaged or frayed LAN wires. If you identify any visible damage or irregularities in the LAN wire or its connectors, consider procuring a replacement cable to rectify the situation.

Occasionally, a faulty Ethernet port on your router may be the culprit. It’s worth noting that scenarios can occur where WiFi functions properly while Ethernet remains non-functional on a particular device.

At times, the root cause might stem from an Ethernet driver malfunction. Moreover, discrepancies in communication between your router and the device are possible culprits. This could involve factors such as a compromised LAN wire, a malfunctioning Ethernet port on either the router or the computer.

In summary, achieving seamless internet connectivity entails the choice between a wired or wireless connection. Yet, potential complications may arise from issues with LAN wires, router Ethernet ports, driver malfunctions, or device-specific discrepancies. Thorough investigation and resolution are essential for restoring optimal connectivity.
