How To Check Network Cable Without Tester

If you are setting up a new network or troubleshooting an existing one, having a cable tester is extremely helpful. However, not everyone has access to a cable tester. In such a situation, there are some other ways to check network cable functionality without a tester.

Method 1: Visual Inspection

Start the cable check process by looking at the cable and checking for any visible damage or wear. Look for any breaks, kinks, and frayed parts of the cable. If there is visible damage, there’s a high likelihood that the cable may not work.

Method 2: Swapping Cable

Another simple method is to swap the cable with a known working cable from another device. Connect the new cable to the network port and check for Internet connectivity. If the Internet starts working after the replacement, then the previously used cable was faulty.

Method 3: Command Prompt Test

There is a simple command in command prompt (cmd) that can help check the status of the network cable:

- Open cmd on your Windows computer

- Type “ipconfig” and hit enter

- If the network cable is connected and functioning correctly, you will see information about your computer’s IP (Internet Protocol) address, subnet mask, and default gateway. If the command does not generate an IP address or shows “Media Disconnected,” it indicates a problem with the network cable.

Method 4: Link Lights

Most network cards come with a built-in visual indicator that shows the status of network connectivity. These indicators are commonly referred to as “Link Lights.” One end is usually connected to the network card while the other end is connected to the switch. If the Ethernet cable is functional, the link lights should illuminate. If the lights are not on, the cable may be faulty.

Method 5: Ping Test

You can also use a ping test to check the network cable for functionality. Pinging is a network troubleshooting process used to check if a host computer is connecting to another computer on the network. Here’s how to do a ping test:

- Open cmd on your Windows computer

- Type “ping 127.0.0.1” and hit enter. This is a loopback address that you can use for testing purposes.

- If you receive replies without any packet loss, it indicates that the Ethernet cable is functioning correctly. If there is any packet loss, it means the cable is not connecting correctly.

Conclusion

While a wire tester is the most reliable tool for checking network cables, there is no need to worry if you don’t have one. The methods described above can help you diagnose problems with your network cables without expensive equipment. These methods can help solve most of the common cable issues. If none of the above methods work, it may be time to invest in a cable tester or call a professional IT technician to help you with the problem.
