The Best Ethernet Cables To Buy in 2023

Sep 30, 2023

Wi-Fi is a crucial part of most of our daily lives, but it hasn't been this way for long. In the early days of the internet, physical cables were required to both establish and maintain any sort of connection.

But even if no longer necessary, a wired connection has a few key advantages. It's almost always faster than the equivalent Wi-Fi, while performance and reliability both tend to be better.

These days, most wired connections rely on an ethernet port. Even if your device doesn't have one, many adapters and hubs can add the port onto your USB-C connection. However, not all Ethernet cables are created equal. Category, length are all important factors to consider – see our buying advice at the bottom of the page for more detailed information.

In this article, we’ll run through eight of the best ethernet cables you can buy right now. The options below are ranked, but that doesn't necessarily mean the top few will be right for you. Each is the ‘best’ for something, so there are no duds here.

And if you’re looking speed up your whole network, remember you could see massive gains by upgrading your router – check out our router reviews to see what we recommend. You may also benefit from improving coverage around your home via a mesh Wi-Fi system.

Don't want to shell out for Cat7? Then go for AmazonBasics’ Cat6 cable, which should be fast enough for most people's needs.

It is available in lengths ranging from 0.9m/3ft all the way up to 15m/50ft. You can even buy some of the sizes in multipacks, perfect if you know you have a few different things to network together.

We’re big proponents of the AmazonBasics range for simple tech accessories and peripherals, and it's no different with ethernet cables.

This is a pretty standard Cat7 cable, so it’ll be plenty fast, and you can grab it in lengths ranging from 0.9m/3ft all the way up to 9.1m/30ft.

These cables from Veetop have a few things going for them. For one, they’re Cat7, which means they offer about the fastest speeds you can get from ethernet.

They’re also flat, so ideal for wiring through the house, and they come in varying lengths including a very short 0.5m/1.6ft option.

There's also a white option which is perfect for running along the top of your skirting boards without being noticed.

This UGreen cable is flat and made to support Cat7 speeds.

Being flat it's ideal when you need to route a network cable under a carpet, or through a doorway or any other situation where a standard round wire won't work.

It comes in lengths from 1 to 20m and only in black.

If 1Gbps is enough for you (and it will be for a lot of people, because it's still faster than your broadband connection) then a Cat5e ethernet cable will get the job done.

In fact, it's worth remembering that it will be faster and more reliable than even the best Wi-Fi systems. That's only useful if the device you want to connect has an ethernet port, but you could use Cat5e cables as backhaul for mesh Wi-Fi nodes: many systems support this.

These Rhinocables come in a variety of colours and lengths, from 12cm to 10m. We’ve picked the 5m cable here, but you can change the colour and length on the Amazon listing page.

A cheap ethernet cable can often end up feeling flimsy and prone to breaking, but not with Mediabridge. It cable feels well made and impressively durable, meaning it should last for many years.

It supports both Cat6 and CaT5e standards, with the former enabling speeds of up to 10Gbps. There are also a wide range of lengths available, all the way from 3 feet to 100 feet.

The blue version you see in the image above is particularly eye-catching, but red, black and white models are also available.

Just make sure you get a legitimate one. There are knock-offs doing the rounds, but they don't have Mediabridge's signature black writing on the cable itself.

At first an ethernet extension cable might seem like an unnecessary bother – surely you can just buy a longer cable for about the same price – but there's an extra benefit you might not think of.

If you’re going to run the cable anywhere it could be a trip hazard, this extension could protect your computer or router's ethernet port in case the cable gets yanked out unexpectedly. Instead of risking damaging the hard-to-replace port on your device, the extension lead could take the brunt of it, leaving you with a much cheaper replacement to worry about.

This version is also Cat6 with shielding, so should ensure high enough speeds – just make sure you pair it with a similarly speedy cable.

It you already have several short ethernet cables lying around, search for RJ45 couplers on ebay or Amazon as they let you join leads together and usually cost very little.

Some outdoor ethernet cables come with RJ-45 connectors at each end, but if you’re routing the cable through a wall, you’ll have to cut those off anyway – or drill unnecessarily large holes.

The best way is to buy a reel as long as you need, and cut it to length. Kenable's unshielded outdoor cable has solid copper cores and a PE sheath which is weather resistant and can be buried underground. For wall mounting, use 7mm cable clips.

It only comes in black, but as it's Cat6 it's capable of gigabit speeds – if the rest of your home network is up to it.

This is the most important thing to consider, as different ethernet categories can carry wildly varying speeds and levels of interference. The options you’re mostly likely to see are Cat5e (the ‘e’ stands for enhanced), Cat6 and Cat7.

As you might have guessed, higher numbers tend to mean faster speeds. Cat5e is rated for 1Gbps and bandwidths of 100MHz, Cat6 offers up to 10Gbps at up to 250MHz bandwidth, and Cat7 can go as high as 100Gbps with bandwidths up to 600MHz.

The other major difference is that Cat7 cables are always shielded, which helps reduce interference and crosstalk. Cat6 cables are sometimes shielded, though retailers often aren't clear when they are and aren't, and Cat5e cables never have shielding.

Since most ethernet cables are fairly cheap, there's an argument for buying Cat7 cables – especially for shorter (and thus cheaper) cables. However, most users won't see any real speed benefits from Cat7, so Cat6 is probably the sweet spot for most – unless you want to be certain you’re future-proofing your cabling.

After category, length is the next most important element of an ethernet cable. Partly that's obviously just a question of how far you need the cable to reach, but it also relates to speed and performance.

Speeds can drop off over longer distances, especially with the more modern cables – for example, that Cat7 speed of 100Gbps is only up to a range of 15m, while a Cat5e maintains its highest speed for up to 100m.

Still, the average consumer isn't likely to be cabling anything anywhere 100m, and even 15m is probably longer than many people will need for their homes, so we wouldn't worry about this too much – just try to avoid buying a 50m cable when you only need it to stretch across one room.

Rather than the traditional round look, some ethernet cables are available in a flat design.

This may bump up the price ever so slightly, but could be well worth it if you expect to thread the cable under any doors or lay it under a rug or carpet. It’ll make a big difference to how much you notice it.

The advice above applies mainly to cables for indoors. However, if you’re going to run cables externally, it's not a great idea to buy standard indoor Cat5, 6 or 7.

Outdoor cable should have a PE coating which won't degrade and turn brittle as standard PVC coatings will. Also, outdoor Ethernet cables have solid copper wires, not the multi-strand wires that indoor cables have.

This means outdoor network cabling isn't as flexible, but it's designed to be tougher and for those solid cores to be installed into Ethernet faceplates. And it's a good idea to use faceplates instead of just attaching RJ-45 connectors to the ends. Faceplates are inexpensive and lend a much more professional finish.

If you’re going to run the cable in the ground, then you’ll need ‘direct burial’ cable which is designed to withstand moisture. It's also possible to buy shielded outdoor Ethernet cable which prevents interference.

Outdoor cable generally comes on reels from 20m up to 305m, and you’ll need a special ‘punch-down’ tool to push the wires into the connectors on the faceplates. When choosing, watch out for cheaper ‘CCA’ cable – copper-coated aluminium. This will not carry power, so it's no use for connecting CCTV or PoE (power-over-ethernet) devices.
