For optimal internet speed, the recommended method of connection is using an Ethernet cable directly to the router. However, there may be instances when the router fails to detect the Ethernet cable. In such cases, you can follow these steps to troubleshoot the issue before resorting to calling a technician.
While contacting a technician is the easiest solution, there are simple checks you can perform to potentially resolve the problem on your own, even if you’re not familiar with routers or fiber connections.

Try another jack
When facing such situations, the initial step is to attempt using a different Ethernet port. If the router fails to detect the cable when connected to a specific port, it is advisable to try another one. This simple action can help determine if the issue lies with a damaged or malfunctioning port, while the others may be fully functional. Checking alternative ports is a quick process that only takes a few seconds, and it is likely one of the initial troubleshooting options that comes to mind.
Check the wire
If changing the plug did not resolve the issue and the router still fails to detect the Ethernet cable, it is worth considering the possibility of a faulty cable. To determine if the cable is the culprit, it is recommended to replace it with a different one. Most households typically have multiple cables readily available, making this step convenient. By connecting an alternative cable to the various ports, you can assess if the connection is established successfully.
While specialized network cable testing devices are available for purchase on platforms like Amazon, they may not be necessary for occasional users. Instead, testing the cable on other devices can serve the same purpose. For instance, connecting the cable to a computer or Smart TV and checking if the internet connection functions properly can help identify if the cable itself is faulty. If the cable fails to establish a stable connection, it is a clear indication of an issue with the cable itself.
Crimp the wire
Crimping the cable is an alternative option that you may consider, although it may not be accessible to everyone. Not everyone possesses a crimper at home, but if you do, it could potentially resolve the issue of the router not detecting the Ethernet cable. By crimping both ends of the cable, you can determine if this action resolves the connectivity problem and allows the Ethernet cable to function correctly.
It is important to note that crimping requires some basic knowledge and patience, and it may not be worth the effort if you are unfamiliar with the process. If you lack the necessary expertise or do not have someone in your vicinity who can assist you, it is advisable to skip this option and proceed to the next one.
Change the wire
When it comes to selecting a new network cable, it is essential to consider certain key factors. Firstly, it is important to prioritize quality cables and consider replacing them if you have been using the same ones for an extended period. It’s crucial to understand that not all cables are created equal and they come in different categories, each with its own capabilities. Some cables may not support the maximum speed provided by your internet service, for instance.
When choosing a cable, pay attention to its maximum speed and supported frequencies, as these specifications can vary. It is advisable to invest in a CAT 6A or higher Ethernet cable if your current cable is damaged or outdated. Previous cable categories are considered deprecated and may cause issues with your internet connection. By selecting an appropriate cable and ensuring it meets the necessary standards, you can optimize your network performance and minimize potential problems.
Contact your operator
If all troubleshooting attempts have been unsuccessful and the router still does not detect the Ethernet cable, it is possible that there is an underlying issue with the router itself or a problem beyond your ability to resolve. In such cases, it is recommended to contact the customer service of your internet service provider and report the problem with your router. They may provide guidance on potential solutions or schedule a visit from a technician.
The technician will assess the situation, identify the source of the problem, and perform necessary repairs. If the issue cannot be resolved, they may consider replacing the router with a new one to ensure proper functionality. It is important to communicate with your service provider to initiate the necessary steps and resolve the connectivity issue effectively.
