The 9 Best Ethernet Cables for 2021

You might have bought some Cat-5 Ethernet cables a few years ago, but as time passes, it’s probably time to think about upgrading them to a more modern, more capable option. Unfortunately, the list of Ethernet cable options has not become any less complicated over the years.

Everyone has different needs for their network setup, so we’ll walk you through the Cat-5e to Cat-8 standards to help you understand which is right for you.

Want to know which cable is right for you? Check out our guide on how to choose an Ethernet cable to learn the speed differences, why Cat-7 is a bit of an oddball, and which type may be the best for your setup.

The best Ethernet cables

DBillionDa Ethernet Cable — Cat 8

The DBillionDa Ethernet Cable.
  • Length: 20 feet
  • Warranty: 18-month warranty
  • Max bandwidth: 2,000MHz

Cat 8 is overkill for most, but if you want the best of the best in terms of shielding and performance, it’s as good as it gets. This particular gold-plated version comes in sizes from 3 to 100 feet and supports 2,000MHz bandwidth and data transmission up to 40Gbps. Cat 8 cables are also waterproof, anti-corrosion, and use more durable PVC material for indoor or outdoor projects. It’s an ideal pick for professional or personal cable management and could be a noticeable improvement in performance, too.

Ugreen Flat Ethernet Cable — Cat 7

The Ugreen Flat Ethernet Cable.
  • Length: 10 feet
  • Max Bandwidth: 600MHz

The flat design of this Ethernet cable is an alternative option that some may prefer depending on the installation. Flat cables are a bit more resistant to forming classic tangles and are easier to run under carpets, beneath doors, or in cracks along the wall. The RJ45 connectors are gold-plated and over-molded for extra durability, with a shape that’s meant to resist catching on other cables or objects while you’re working. Lengths range from three feet to 50 feet.

Dacrown Weatherproof Ethernet Cable — Cat 8

The Dacrown Weatherproof Ethernet Cable.
  • Length: 30 feet
  • Max Bandwidth: 2,000MHz

If you know that your Ethernet project is going to require running cables outdoors where they will be exposed to the elements, you need a durable option that can handle it. This Cat 8 cable, available in sizes up to 150 feet, has a pure copper core, aluminum foil shield, woven mesh shield, and thick PVC outer layer. That makes it highly water and UV-resistant, so you won’t have to worry about issues developing down the line.

Cable Matters Snagless Ethernet Cable – Cat 6A

The Cable Matters Snagless Ethernet Cable.
  • Length: 25 feet
  • Max bandwidth: 500MHz

Category 6 Ethernet cables were eventually updated with an optimized 6A version, with thicker conductors, durable jackets, and a significant speed upgrade — 10GB at up to 100 meters — that made it an excellent option for those who couldn’t work with the Cat-7 changes. This particular version of the cable also includes additional shielding, gold-plated contacts, and boots for durability. The snagless clip protector also helps prevent accidents or cable damage while work (or if someone stumbles on one of the cables).

Ugreen Ethernet extension cable — Cat 6

The Ugreen Ethernet extension cable.
  • Length: 1.5 feet
  • Max Bandwidth: 250MHz

If you’re happy with your current Ethernet cable, you may not want to replace it entirely. However, a new device or new router setup, etc., may mean that your current cables aren’t quite long enough to get the job done. This Cat 6 extension is specifically made to extend a current cable over a longer distance, and you can move it between Ethernet cables as needed when you have a length issue.

Monoprice SlimRun Ethernet Cable 10-pack — Cat 6A

The Monoprice SlimRun Ethernet Cable 10-pack.
  • Length: 5 feet
  • Warranty: N/A
  • Max bandwidth: 500MHz

These “SlimRun” cables are designed specifically for narrow spaces, running under carpets or baseboards, or saving space (and encouraging more airflow) in packed server rooms — they’re half the size of standard Cat-6A cables. If you are dealing with more complex setups, there are also a variety of color options to choose from for even more organization possibilities. Here we’ve chosen a pack with a shorter length for connecting multiple devices to nearby Ethernet ports. If you are running these slim cables at a longer distance, they are available at up to 50 feet in length.

CableGeeker Flat Black Cable with Sticky Clips — Cat 6

The CableGeeker Flat Black Cable with Sticky Clips.

Cables Direct Online 30FT Cable — Cat 5e

The Cables Direct Online 30FT Cable.
  • Length: 30 feet
  • Max Bandwidth: 350Mhz
