Ethernet Connection Troubleshooting Guide

If your internet isn’t working over a wired (Ethernet) connection, follow these steps:

1. Check the cable connections

• Make sure the Ethernet cable is securely plugged into both your modem/router and your device.

• If available, try a different port on the modem/router.

2. Test with another cable

• Ethernet cables can get damaged over time.

• Swap it out with another cable to rule out a faulty one.

3. Restart your equipment

• Turn your modem/router off at the wall for 30 seconds, then switch it back on.

• Restart your computer or device as well.

4. Try another device

• Connect a different device (such as another laptop or desktop) with the Ethernet cable.

• If the second device works, the issue is likely with your original device’s network settings.

5. Check for lights

• Most Ethernet ports have small lights that blink when a connection is active.

• If there are no lights, the port, cable, or device may not be working correctly.

6. Set up your network adapter

Your device needs to recognise the Ethernet connection:

On Windows:

1. Click the Start Menu → type Control Panel → open Network and Sharing Centre.

2. Select Change adapter settings.

3. Right-click Ethernet → choose Enable (if it’s disabled).

4. If it’s already enabled, right-click Ethernet → Diagnose to run Windows troubleshooting.

On Mac:

1. Go to System Settings (or System Preferences) → Network.

2. Select Ethernet from the list on the left.

3. Make sure the status says Connected. If not, click the gear ⚙️ icon and choose Make Service Active.

4. If it still doesn’t connect, click Advanced… → TCP/IP tab → select Renew DHCP Lease.

7. Update or reset network settings

• Make sure your device’s software is up to date.

• If the adapter is still not working, you may need to reset your network settings to restore defaults.
