The best Ethernet cables of 2026
Which category to buy, the cables worth paying for, and the one label to avoid.
For almost every home, buy a pure-copper Cat 6 cable, such as Cable Matters' snagless Cat 6. Get Cat 6a only for 10 Gbps runs. Skip Cat 8: it is built for data centers. A wired connection does more for ping and video calls than any router upgrade.

Quick picks
The picks
Cable Matters Cat 6 Snagless
Pure copper, snagless boots that don't catch when you pull them through furniture, and every length from 1 to 100 feet.
Round cables are harder to hide under rugs; see the flat pick.
Monoprice SlimRun Cat 6A
About half the thickness of a normal cable, so it bends around desks and racks easily and still supports 10 Gbps over short runs.
Thin wire limits length. Keep runs under about 30 feet.
Cable Matters Cat 6a
For a 10 Gbps NAS, router or fiber plan, Cat 6a carries the full speed over long distances.
Thicker and stiffer than Cat 6.
UGREEN Flat Cat 6
A flat cable that runs under carpet, along baseboards or under a door without a bump.
Flat cables pick up more interference over long runs. Keep them under about 50 feet.
Which category do you need?
Cat 6 handles 1 Gbps at any home distance and 10 Gbps up to about 55 meters. Cat 6a handles 10 Gbps up to 100 meters. Both cost little, so the category matters less than buying pure copper.
Avoid cables labeled CCA (copper-clad aluminum). They are cheaper, break more easily and can fail on long runs and PoE. Look for 'pure copper' or 'solid copper' in the listing.
- Cat 5e: fine for 1 Gbps, but no cheaper than Cat 6
- Cat 6: right for most homes and plans up to 2 Gig
- Cat 6a: for 10 Gbps runs
- Cat 8: made for short data center links; no benefit at home
Laptop without a port? Add one with a USB-C hub with Ethernet. To confirm your cable connects at full speed, check your link speed in Windows 11.
Ethernet categories compared
| Category | Top speed | At full length | Good for |
|---|---|---|---|
| Cat 5e | 1 Gbps | 100 m | Plans up to 1 Gig |
| Cat 6 | 1 Gbps (10 Gbps up to about 55 m) | 100 m | Most homes, gaming, 2.5 GbE |
| Cat 6a | 10 Gbps | 100 m | Multi-gig plans, NAS, long runs |
| Cat 7 | 10 Gbps | 100 m | Not a TIA standard; buy Cat 6a instead |
| Cat 8 | 25–40 Gbps | 30 m | Data centers; no benefit at home |
Flat or round?
Flat cables slide under rugs and doors and are easy to tuck along baseboards. Round cables have better shielding and twist, so they hold full speed more reliably on long runs and near power cables. For a short run to a desk or console, flat is fine. For anything over about 15 m, or behind a TV stand full of power cords, use round.
Outdoor and in-wall cable
Patch cables like the picks above are for indoor use between a wall jack and a device. Inside walls, use solid-copper bulk cable rated CMR (riser) or CMP (plenum) to meet building codes. Outdoors, buy cable labeled outdoor or direct-burial, which resists sun and water; regular cable cracks within a few seasons.
How we picked
We compared published lab tests, owner reports and maker specs, and ranked on:
- Pure copper conductors
- Snagless connectors and build
- Range of lengths
- Price
More on our process is in how we research.
Others we considered
- Amazon Basics Cat 6: Cheap multipacks of short cables; fine for patching a router.
- Cat 8 cables: Not harmful, but no faster on home gear.
- Powerline adapters: For rooms you can't run a cable to; see our powerline guide.
Questions
Is Cat 8 worth it?
Not for a home network. Cat 8 is rated for 25 to 40 Gbps over 30 m, but home routers and computers top out at 10 Gbps, which Cat 6a already handles. Many cheap "Cat 8" cables also fail the standard. Buy Cat 6 or Cat 6a.
Will a better Ethernet cable make my internet faster?
Only if your current cable is damaged or Cat 5. Any Cat 6 cable carries the full speed of home plans.
How long can an Ethernet cable be?
Up to 100 meters (328 feet) for 1 Gbps.
Is Ethernet better than Wi-Fi for gaming?
Yes. A cable removes Wi-Fi interference and keeps ping steady.
