Ethernet cables are one of the most common types of computer cables. They’re used to connect computers, servers, and other devices to local area networks (LANs).
Ethernet cables come in different types, each with different maximum lengths and bandwidth capabilities. It’s important to know which type of cable you have so you can use it properly.
The following tests will help you determine if your Ethernet cable is working properly:
Check The Lights On Your Modem or Router
The first thing that you should do when you suspect that your Ethernet cable isn’t working is to check the lights on your modem or router. If the light is green and flashing, it means that there’s no problem with the connection between your modem or router and computer.
If the light is orange and flashing or solid orange, then there might be an issue with your connection. In this case, try resetting your modem and router before trying again.
Check The Connection at Both Ends Of The Cable
This is the first thing you should always do when you suspect an Ethernet cable problem.
Make sure both ends of the cable are securely plugged into their respective ports: One side into the router or switch and another side into a desktop computer or other device.
If one end isn’t plugged in all the way, try wiggling it back and forth until it clicks into place; this is sometimes necessary for older equipment that doesn’t have locking tabs on its connectors.
For new equipment with locking tabs, it may help to use a flathead screwdriver or pair of tweezers to gently squeeze them together until they engage properly with each other.
Check for Physical Damage
It is crucial to check if there’s physical damage to your Ethernet cable. Check for frayed or torn wires near where they connect with one another.
You should also check for any kinks or bends in the cable itself. If there’s anything out of the ordinary, try replacing your Ethernet cable with a new one.
Use an Ethernet Diagnostic Tool
One of the best ways to test whether your Ethernet cable is working properly is by using an Ethernet diagnostic tool.
These tools can be purchased online or at any computer store and will allow you to test the quality of your connection.
The device will display real-time information about your internet connection, including how much data is being transmitted and received, as well as how much bandwidth is available on your network.
If any issues are detected, such as packet loss or latency (slowness), then these tools will also provide suggestions on how to fix them.
Check Your Cable Length
Cable length is an important consideration when setting up an Ethernet network. The farther away two devices are from each other on the network, the weaker their connection can be but this depends on the cable type; some cables cannot transmit data well over long distances.
This can cause slow data transfers or even disconnections if there isn’t enough signal power available between two devices across a long distance.
You should test your Ethernet connection with both short and long cables so that you know what works best for your setup and environment before commencing with installation or repair work on your equipment.
Check The Connection Signal On Your Computer or TV
The other thing you can do to check if your Ethernet cable is working is to check the connection signal on your computer or TV. This can be done by going to “My Computer” or “My Network Places” on your computer and clicking on the Ethernet connection. If there is no connection information on this window, then it means that the cable is not working.
Check Internet Speed
If there is connection information, then it means your Ethernet cable is working properly. The next step is testing the speed of the Ethernet cable. To do this, you will need an Internet speed test tool.
Run the speed test on your computer or TV and see if the results are correct.
Replace Devices that are Faulty
If you get good results with the speed test, then your modem, router, or hub may be faulty. You should contact your ISP to see if they have any recommendations for replacing these parts or have them replaced under warranty if you are still within the time frame specified by their policy.
If you do not get good results with the speed test, then there may be something wrong with your Ethernet cable itself which will need replacing.
Check Your Network Settings
If you’re having trouble with an Ethernet connection, it could be as simple as having something wrong with your network settings on your computer. If this is the case, then this is the step you can take to make sure everything is set up properly:
On Windows computers: Open Control Panel, click on Network and Sharing Center, click View Status, then select Local Area Connection and check if the settings are okay, if not, configure them properly.
