[Longer] Ethernet Extension Cable – 2023 Buyer’s Guide

Connecting to the internet at top speed is more important than ever before. You are constantly streaming data in one form or another, and you don’t want to lose any quality. 

Wi-Fi is nice, but nothing beats an ethernet connection. You can find many different styles and lengths for an ethernet extension cable so that you can stay connected. 

How Long Can You Go?

On average, the most extended ethernet cord you should run for any component of your system is 100 meters or 300 feet. Anything beyond that will need other pieces to keep up speed and data transfer quality. 

The higher the speed of the cord, the shorter the distance it works at top speed. Don’t worry though, 300 feet is about the span of a football field, so it gives you a lot of space. There are also options to go longer. 

Adapters and Extenders: Are They Worth It? 

You can add to the 300 feet distance by using an ethernet extender or adapter. When it comes to gaining distance, extenders are the better option. 

Adapters have a lot of problems. Every time you plug an adapter in, there is a chance you are going to slow down the signal and increase interference. Therefore, one continuous cord is a better option than putting together multiple smaller cords.    

An ethernet cable extender allows you to take in the signal over longer distances using heavy-duty copper cables. The standard extender supplies a large ethernet cord, and you plug in at both points. You then have to run the cord the whole way. 

A powerline adapter uses your home or office power cords to transfer the data. These have small cords at the router and the adapter but only work in places with connected power systems. Additions and individual office space may not work with this system.

Features of an Ethernet Extension Cable 

When looking for an ethernet extension cable, you want to find one that covers the distance you need and meets your speed requirements. 

What Does CAT Mean?

CAT stands for category and is a quick way of telling you the speed and bandwidth of the cable. You will see cords with CAT ratings from three to eight. Going with cords faster than your system won’t do anything but cost more. 

Going with cords slower than your system will cause your internet speeds to go down. The dip in rate is because the cord will become the weak link in the communications chain. Try to find a CAT cord around the same speed as your internet.  


When you get the cord, you don’t want to buy one with a ton of extra space. The longer the cord, the more likely you are to slow down your connection. It will also make it harder to hide the cord when you finish setting it up. 


You want to try to match your modem speed to your cord speed. If you don’t know your internet speed, you can do a free speed test. Once you have an idea, always make sure to get a cord that is faster than your nets average speed. Then, if you get an internet boost, your cord won’t slow you down. 


Some lower-level ethernet cords offer shielding, but it doesn’t become necessary until CAT 7. Once you go above a CAT 6 cord, the ethernet cord will cause too much interference. This shielding helps stop the cord from disrupting other electronic signals in your home and office. 

The process usually involves adding a foil wrap to the cord. For most homes and offices, this works fine. However, you may need better shielding if you have lots of sensitive equipment.

To get the best ethernet cable, you want to skip the cable adaptors and get one long cable instead. It will make your life easier, and your internet will be faster overall, even if a signal has to travel a little further. 

You can usually get cords in any length up to 300 Ft. If you have to go past that, you will want to look into an extension system.

Running Ethernet Cables 

Once you get the best ethernet extension cable, you want to make sure that you run it to your devices in the best possible way. Ethernet cables can’t deal with a lot of stress. This limitation means you don’t want people walking on them every day. 

Whenever possible, run the cord through the walls and floor to make it look cleaner. Attics and basements make running cord much easier if you have that option. 

When it has to be in the open, run it up walls, and avoid laying it across the floor. It is easy for people to trip on the cord, which can cause problems. 

Getting staples and picture nails can help you keep it up and out of the way. Be careful not to puncture the cord when you are hanging it, or you may cause extra interference or signal failure. 

Conclusion on Ethernet Extension Cables

An Ethernet extension cable can get you up to 300 ft. of internet connectivity. It is best to use one single cord rather than adapting multiple smaller ones. If you need a system that will go even further, you can look into ethernet extender systems that use a phone or electrical cord to up the distance.

And if your device doesn’t have an ethernet port you can use the NAS adapter for that.

Getting the right cord for the job can be tricky, but you can find one that will work for you by following a few easy steps. Once you have the cord, you want to make sure it stays safe so it will carry your signal for a very long time.
