Solve Internet Cable Visibility Issues With Your Router

Method 1: Checking the LED

First of all, it is recommended to inquire about network availability even if the router light is not on. The situation that has arisen may be caused by software problems or a trivial failure of the lamp itself, which is responsible for the visibility of the Internet cable. If the Internet connection is correct, it means that the problem is with the device and not with the network cable.

You can try updating the firmware if you suspect that the light does not turn on due to software reasons, but this situation is usually resolved by replacing the light at a service center or purchasing new network equipment. You can leave it as is, as there are no functional restrictions caused by the absence of the bulb.

Method 2: Checking the network connector

The next reason the router may not see the Internet cable is a problem with the connector or the cable is not connected properly. Make sure the cable from your Internet Service Provider is connected to the WAN, Internet, or ADSL port. Each connector is typically labeled and color-coded, so it's easy to figure out.

If the cable is inserted correctly, unplug it and make sure the port itself is not physically damaged. In addition, it can be cleaned of dust, since dust on the pins also causes these types of problems.

Method 3: Check the condition of the cable

Your Internet Service Provider's cable may be broken somewhere or have external physical damage - the lack of visibility is most likely due to precisely this situation. You will simply have to inspect the entire length of the cable and try to locate the faults. If none are found, proceed to the next method.

To clarify, when a private home is connected to the Internet, ISP staff bring the cable directly into the home underground or through a power line, so a small or important part may be out in the open. Go out to the patio and look for such a cable, check if it is broken or has been detached, for example, by a strong gust of wind. If you find faults, contact your supplier directly and request a repair service.

Method 4: Check the splitter connection

Now, in some areas, the ADSL type of connection is still popular, in which the Internet cable connects directly to the telephone line, and the connection is arranged through a domestic telephone. If this is your network, look for a splitter next to the router that looks like the one shown in the image below.

Make sure all cables are properly connected, seated securely in their connectors, and free of visible defects and physical damage. If there is no problem with this unit, go to the next method.

Method 5: Check your home phone

This option applies to the same holders of the ADSL connection. One of the cables coming from the ISP is connected to the phone. If it is accidentally detached from the connector or for some reason there is a fault, respectively, the router itself will not see the Internet cable. Also check this device and, if found, correct the problem.

Method 6: Reassign the network access connector

We put this method last, as it will be suitable only for owners of certain router models, including ZyXEL and ASUS gamer network devices. The essence of the method is to change the port used for the wired Internet connection through the router settings, since the signal can also be received through the LAN port. Use the following instructions to check if the settings are correct or if you want to change the port, for example when the WAN port is broken.

  1. The first task is to enter the Internet center of the router, which is done through a browser. If you haven't found it before, check the instructions in the link below to understand all the nuances.

  2. Next, in the web interface, select your network connection profile and proceed to change your settings.
  3. Find the parameter responsible for changing the port your ISP's cable connects to. Change the value or just find out the value, and when you're done, remember to apply your settings and send the router in for a reboot.

If none of the above methods are helpful, feel free to contact your ISP technical support and find out if there is any technical work being done on the line, as it may also be the cause of the situation in question. In addition, you can ask the staff for other solution methods or ask them to check the network access of your line themselves.
