Ethernet cables are one of the most important elements of any electric system. If they don’t work properly, the rest of the network would become nonfunctioning. Any type of disruption would make faulty Ethernet Cable’s performance slow.

Today we will be checking out some of the signs that indicate if your cable is performing up to the standard or not.

It Often Loses Connection

If you plug the cable into the Ethernet adapter and the light doesn't turn on, it could indicate a problem either with the cable or the adapter. Also, if you are seeing display messages like ‘network connection is lost’ or ‘no connection’, then something’s wrong with the system’s ethernet cable. In such cases, make sure that you’ve connected the cable properly. Otherwise, a bad cable will not work even if properly connected.

You Always Have Slow Connection

If your connection keeps dropping or runs very slowly, there are chances that you have a damaged cable. If there is a tear on your cable, it can break down the internal wire connection and can cause a short circuit. If you find a bent cable, try straightening it with your hands. In case it is too beat up, you will need to replace it.

Connection Restored With A Wiggle

Wiggling the cable re-establishes a failed connection. If you do this too often, it also means that you have a broken connector on your hands. Ethernet cables have a built-in plastic lever that secures the cable into place within the Ethernet adapter port. If this lever breaks, the connection will drop.

Do You Keep Replacing Them?

This is the ultimate sign that you need to check your network ecosystem. If replacing the ethernet cable eliminates the problem, then it’s well and good. But if the same problem persists with the new cable, the problem relates to the network. There could be some malfunction happening.

In such cases, there are three types of network cable issues you should look for:

Testing Connectivity Issues

These issues are majorly because of a faulty cable. Consider taking a quick test to check the connectivity. To check, try plugging the suspected cable into the network device or network connector of another computer. Typically, the jack you plug the cable into is the part of a network adapter. It provides the interface between a computer/ network device and the network cable.

These adapters have one or two LED lights which state that an established connection exists and transmission is happening on the line. After you plug the cable into the network adapter, the link LED should be on to indicate a connection. If it doesn't light up or flash, there might be a problem with the cable or its connector, or both of them.

Testing Performance Issues

If your connection is failing or transmitting data at much slower speeds, you have performance-related issues. This happens generally due to a damaged or bent cable. Usually, you can straighten a bent cable to solve the problem. And if the problem persists, you might have to replace the damaged cable.

To troubleshoot, visually scan the length of the cable and look for sharp bends, kinks, or other physical faults in the cable. If you find a sharp bend or kink in the cable, straighten the cable and check if the problem is solved.

Before replacing it make sure to shake the cable lightly at the connector side to see if the connection can be re-established. If so, then the problem is with the connector. Which also means that you need to repair or replace the entire cable.

Testing Continuity Issues

If there are any faulty connectors, bends in a cable, continuity issues can occur. They can also occur by a cut or a sliced cable, any kind of penetration by objects like a nail, staple, screw, etc. or electromagnetic interference. If you can visually scan the cable length, check for any of these causes. If not, test it with a continuity tester. An electronic device is specially made for this purpose. Such a device can help detect problems caused by EMI, or radio frequency interference.

Still Got Problems?

Even after doing all this if your network keeps failing, it is very likely that issues are with local network configuration, one or more of the network connectivity devices. Like adapters, switches, routers, and so on. Such faults will require a higher level of troubleshooting.
