How to Extend Ethernet Cable? – Step-by-Step Guide

Ethernet cable plays a significant role in providing you with the fastest internet connection than Wi-Fi. But what if your Ethernet cable is too short to reach the devices, or do you want to increase the length of your existing Ethernet cable?

If you’re going to set up your home network, it can be a little difficult to know just how long of an Ethernet cable that’s needed.

Usually, though, there are several different lengths available so the simplest thing would be to buy a longer ethernet cable and fold the extra length.

Since you already have the cable, but it doesn’t extend to your desired location, here is a guide to show you how to make the Ethernet cable reach further.

What is the Limit of an Ethernet Cable?

Most cables have a maximum length of 100m, so it is recommended to not go over this limit.

If you try to go further than 100 meters with the ethernet cable more signal is lost and if your network isn’t set up correctly there’s a high chance to cause problems like packet loss or disconnections.

So, if you want to increase the length of your existing Ethernet cable then this guide is for you. It’s simple and very cheap, so you don’t have to worry about breaking the bank.

How to Extend Ethernet Cable?

Here are some ways.

Extend Ethernet Cable Using RJ45 Inline Coupler

Technically, there isn’t any extension cable introduced in the market that connects two Ethernet cables with each other.

But, the RJ45 coupler is there to perform this action. It is a device that is used to connect two Ethernet cables together in order to extend their length.

The RJ45 inline coupler has two female Ethernet ports on both ends that enable two cables to insert on each side and works as a keystone jack.

You can simply use this device by taking one Ethernet cable and plugging it into one side of the coupler. Then take the second cable and insert it on the other side. By doing this, you will be able to extend your Ethernet cable’s length and reach any corner of your home.

Anyhow, you would find the RJ45 coupler very cheap and they are extremely user-friendly. This mini device comes in a ready-to-use form.

All you need to do is insert the two Ethernet cables to each end and enjoy a fast internet connection.

Extend Ethernet Cable Using Ethernet Switch

Another way to extend the Ethernet cable is by using an Ethernet switch. The switch works as an intermediary between your router and the computers connected to it.

It allows multiple devices to connect to a single port on the network. Gamers use these ethernet switches to connect their gaming consoles with their gaming ethernet cables.

Basically, an Ethernet switch can also function as a splitter for one RJ45 connection into multiple ports that are linked back to the main port.

To use an Ethernet switch, simply connect it to the router and then take one end of the cable and plug it into its Main port. Then you can insert all your devices at the different ports as well as they will receive data from your network.


Let’s see what people have to ask.

Can I Connect Two Ethernet Cables Together?

Yes! You can use an Ethernet coupler, which is the cheapest and simplest tool to connect two Ethernet cables with each other.

Does the Length of the Ethernet Cable Affect Latency?

Well, the longer the cable, the higher the latency. However, this impact could be about one Nanosecond per foot cable. It means there is a very slightly noticeable difference in the ping.

Final Words

A short-wired network could be a serious issue because it can mess up the entire networking system in your home; still, it can be fixed easily.

Though, you can pick a few inches longer Ethernet cable to make it reach the desired location. Yet, you can simply roll the extra cable up and manage it hassle-freely.
