How to test Ethernet Cable without a tester?

Ethernet cables play a big role in our digital lives. They give us internet access for things like work and entertainment.

But sometimes, these cables can have problems that make our internet not work well. You don’t always need a special tool called a cable tester to find these problems.

If you’re wondering how to test Ethernet cable without a tester, this guide will teach you a simple way to check your cables without using a tester.

Testing an Ethernet Cable Without a Tester: A Guide

To check your Ethernet cable without using a tester, you’ll only need two computers and the Ethernet cable you want to test.

Checking Connectivity

First, make sure both ends of the Ethernet cable are securely plugged into the right devices, like computers and routers.

Take a look at the cable connections. Give them a gentle wiggle to see if they’re firmly in place. Make sure none of the plugs are loose or not connected properly.

Using Ping to Test Your Connection

The Ping command is like a helper that checks if your network is working well. Here’s how to do it:

  • Open a special window called the command prompt or terminal.
  • Type in “ping” and then the IP address you want to check, like “ping”
  • Press Enter, and your computer will send some packets to that IP address.
  • You’ll see numbers that show how fast the packets go and if they come back.

Software Tools for Checking Your Ethernet Connection

You have some computer programs that can help you test if your Ethernet is working well.

These tools can find problems with how fast your network is, if data gets lost, and how long it takes for data to travel.

Here are of these tools
