The Best Ethernet Cables For 2021

The Best Ethernet Cables For 2021

Ethernet cable specifications are complex and dull, but we've done the hard work for you, explaining which ones to buy.

Wireless connections are undeniably convenient. But if you're looking for the best speed, performance and reliability then wired is the way to go. 

Whether you call them Ethernet cables or network cables, it isn't as simple as grabbing the nearest cable and hoping for the best. Not all ethernet cables are created equal, and to make sure you’re getting the best speed, you need to make sure you buy the right ones. That’s where we come in.

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.

Ethernet cable buying advice
There are basically three main factors to consider when buying an ethernet cable: category, length, and style.

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 600 MHz.

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.

Alongside 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.

Finally, one small thing: many 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. You’ll thank us later.

AmazonBasics Cat7 Cable

AmazonBasics Cat7 Cable
  • From $6.99

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.

AmazonBasics Cat6 Cable

AmazonBasics Cat6 Cable
  • From $6.99
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.

Veetop Flat Cat7 Cable

Veetop Flat Cat7 Cable
  • From $4.99
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.

UGreen Flat Cat7 CableUGreen Flat Cat7 Cable

  • From $5.59
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.

UGreen Extension Cable

UGreen Extension Cable
  • From $5.69
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 for most use - 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.
