Testing a LAN cable without a tester may seem like a daunting task, but it is possible with a few simple steps. Follow the guide below to test your LAN cable and ensure it's working correctly.

Step 1: Inspect the Cable

The first step in testing a LAN cable is to carefully inspect it for any visible damage. Look for any cracks, cuts, or kinks. If you notice any damage, the cable may not work properly, and it's best to replace it.

Step 2: Check the Connectors

Next, check the connectors on both ends of the cable for any signs of damage or corrosion. Ensure that they are seated securely and not loose. Loose connectors can cause connection issues and slow down your internet speed.

Step 3: Use a Known Working Device

To test the cable, you'll need a known working device, such as a laptop or desktop computer. Connect the cable to both the device and your router or modem.

Step 4: Check for Lights

Once the cable is connected, check for lights on the router, modem, or network card on your device, depending on the hardware you're using. If you see green lights turn on in the proper locations, this indicates that the cable is working correctly. If you don't see any lights, there may be a problem with the cable or connection.

Step 5: Check for Internet Connectivity

Finally, test the internet connectivity using the device you connected to the cable. Open a web browser and try to load a website. If the website loads correctly, your LAN cable is working correctly. If the website doesn't load or loads slowly, there may be an issue with the connection, router, or modem.

Conclusion

Testing a LAN cable without a tester may seem like a daunting task, but it can be easily done with a few simple steps. By carefully inspecting the cable, checking the connectors, and testing the internet connectivity, you can quickly determine whether your LAN cable is working correctly. If you're still experiencing issues, it's best to call a professional or replace the cable.
