An alternative solution is contacting your internet service provider if you are not able to connect to the internet using the ethernet cables as they will help you find a solution.
Causes For No Internet Through My Ethernet Connection
Is your ethernet cable plugged in but you do not have an internet connection on your computer or mobile device?
The following are some of the reasons why your ethernet connection has failed:
- Issues with the ethernet cable – even though ethernet cables are pretty robust, sometimes the cable can be ripped or damaged. This will interrupt the connection between the router and your device, preventing the DHCP from correctly giving you an IP address.
- Network drivers are expired – if the software needed to establish and maintain a solid connection has issues, you will experience no internet connection even if the ethernet cable is connected.
- Various malware and viruses – malware programs and antivirus blocks may stop your internet connection regardless of whether you are connected through WiFi or have an ethernet cable plugged in.
- Other causes include:
- Broken ethernet port.
- Incorrect network settings.
- Loose connectivity from either your computer or router.
- Incompatible IP address.
- Internet outage on the ISP’s end.
- Outdated firmware on your modem or router.
- The operating system needs updating.
Easy Fixes For No Internet Through Ethernet Cable
Before troubleshooting, you need to find out whether the issue of no internet is caused by the router or the device you are trying to connect.
You can do this by connecting another device to the same ethernet cable and test it.
If the device establishes an internet connection, then the issue you are having is caused by a specific device.
However, if the other devices are not able to establish connections and behave the same way, then the issue is with the router or the ethernet cable.
Whichever the cause of the problem is, here are the different ways that you can fix the no internet issue:
1. Restart Your Modem/Router and Computer
Before trying any complicated solutions, the first thing that you need to do is restart your computer or router/modem to enable them to go through a soft reset that may be needed for internet access.
You can follow the steps below to reset your modem/router and computer:
- Turn off your computer.
- Turn off your modem/router and unplug them from the power source.
- Leave them disconnected for a few minutes.
- Plug the power cable back into the modem/router and switch on the computer.
- Ensure that the ethernet cable is still connected to the computer and check if the problem has been fixed.
If you have followed the above steps and your modem and computer are reset, but still receiving the ‘no internet access’, you should try the next step.
2. Check For Damaged Ethernet Port
You should inspect the ethernet ports on your router or modem, and computer to see whether they are damaged. If the ports are not in good condition, then this may be the reason why you do not have internet access.
