For most homes, buy Cat 6 for a new patch cable. If an existing Cat 5e run already delivers 1 Gbps, there is no category-based reason to replace it. Choose Cat 6A only for a new fixed run that must carry 10 Gbps across the full 100 m channel. Cat 8 is a short-reach, screened category designed for data-center server-to-switch connections, so it is not a general home speed upgrade.
A cable’s category describes what the cabling can carry. It does not set the speed your internet connection delivers, and it does not upgrade the Ethernet ports at either end. The sections below explain how to match the cable to your actual equipment and path.
Start with the speed your equipment actually negotiates
The right cable depends on three things you can check before you buy anything:
- Your internet plan. Look at the download speed on your ISP bill or account page. A cable rated for 10 Gbps does nothing for a 500 Mbps plan.
- The port speed of each device at both ends of the run. A router, switch, computer or NAS is only as fast as its slowest Ethernet port. On Windows, Settings > Network & Internet > Ethernet shows the link speed the adapter has negotiated. Compare that number with what the device’s specification sheet lists.
- The length and type of the run. A short patch cable between a switch and a desk is different from a cable routed through walls and ceilings.
If the link speed on your devices is 1 Gbps, the cable must support 1 Gbps. Anything faster than that requires a cable and devices that are both rated for it.

What each category is for
Each category below is described using published specifications. These are rated capabilities under standard test conditions, not measured results from any particular home.
Cat 5e: enough for most gigabit homes
NETGEAR Support’s consumer guide, last updated July 2025, lists Cat 5e at 1 Gbps up to 100 m (328 ft). That covers the common gigabit connection in a typical home. Some existing Cat 5e installations may also run 2.5 Gb/s or 5 Gb/s, but not all of them will, because the result depends on the cable that was actually installed. If your devices and internet plan top out at 1 Gbps, keep the Cat 5e cable and move on.
Rank #2
- Cat 6 performance at a Cat5e price but with higher bandwidth
- High Performance Cat6, 30 AWG, RJ45 Ethernet Patch Cable provides universal connectivity for LAN network components such as PCs,computer servers,printers,routers,switch boxes,network media players,NAS,VoIP phones
- Jadaol cat6 standard cable support Cat8 and Cat7 network and provides performance of up to 250 MHz 10Gbps and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), 1000BASE-T/1000BASE-TX (Gigabit Ethernet) and 10GBASE-T (10-Gigabit Ethernet)
- UTP(Unshielded Twisted Pair) patch cable with RJ45 gold-plated Connectors and are made of 100% bare copper wire, ensure minimal noise and interference
- The unique flat cable shape allows for a cleaner and safer installation. You can easily and seamlessly make the cable run along walls, follow edges & corners or even make it completely invisible by sliding it under a carpet.
Cat 6: the practical default for a new patch cable
Cat 6 is the sensible choice when you are buying a new patch cable. NETGEAR’s consumer guide recommends Cat 6 or better for multi-gig-capable devices or ISP service. Cat 6 is also the minimum most people should buy when they want headroom above gigabit without paying for a category built for a much larger job. Its published 10 Gbps reach is discussed in the distance section below.
Cat 6A: for a new fixed run that needs 10 Gbps over 100 m
Cat 6A is the straightforward copper option when you are installing new cabling in a wall or ceiling and need 10GBASE-T to work across the full 100 m channel. NETGEAR lists Cat 6A at 10 Gbps up to 100 m (328 ft). Fluke Networks gives the same full-distance target for 10GBASE-T. Cat 6A matters for a new fixed run. For a patch cable of a few metres, Cat 6 is usually the more practical buy.
Rank #3
- 40 Gbps 2000 Mhz High Speed: The Cat 8 ethernet cable support max. 40 Gbps data transfer and 2000 MHz Brandwith, ideal for gaming and streaming, greatly improving upload and download speed, sound, image and resolution quality
- Excellent Anti-interference: The ethernet cable comes with 4 shielded foiled twisted pairs (F/FTP), pure copper core and gold-plated RJ45 connector, reducing interference, noise and crosstalk, making network speed faster and more stable
- Marvelous Durability: Internet cable wrapped with quality cotton braided cord, which makes the LAN cable stronger and more durable. The test proves that this internet cable can be bent at least 10000 times without broken, very suitable for long-term use
- PoE Supported: All lengths of ethernet cord can support the PoE power supply function except 65ft. You don't need additional power supply when installing a PoE camera, which is very convenient and safe
- Wide Compatibility: With the RJ45 Connector, network cable can be perfectly compatible with computers, laptops, modems, routers, PS5, X-Box and other networking devices. It can also be fully backward compatible with Cat7, Cat6e, Cat6, Cat5e, Cat5
Cat 8: a data-center category, not a home upgrade
Cat 8 is specified for a 30 m, two-connector channel and characterized to 2 GHz, according to Fluke Networks’ Category 8 cable testing guide. It is a screened construction aimed at data-center edge applications, supporting 25GBASE-T and 40GBASE-T. A higher frequency figure looks impressive on a box, but the reach is short, and the applications it targets are server and switching equipment in data centers. A home network with a router, a few switches and a gigabit or multi-gig internet connection cannot make use of those capabilities. That is why Cat 8 is the wrong default for home buyers.
Compare the options side by side
| Category | Published rate and reach | Best use at home |
|---|---|---|
| Cat 5e | 1 Gbps up to 100 m (NETGEAR). Some 2.5/5 Gb/s installations may work, but not all. | Keep existing runs that already deliver 1 Gbps or less. |
| Cat 6 | 10 Gbps: 55 m (NETGEAR) or 35 m (Fluke Networks), depending on the source. | A new patch cable for most home connections, including multi-gig devices. |
| Cat 6A | 10 Gbps up to 100 m (NETGEAR); 10GBASE-T across 100 m (Fluke Networks). | A new fixed in-wall or ceiling run that must reach 10 Gbps over full distance. |
| Cat 8 | 2 GHz, 30 m two-connector channel; 25GBASE-T and 40GBASE-T to 30 m (Fluke Networks). | Data-center server-to-switch links. Not a general home choice. |
Compare categories by the speed your devices support and the length of the run. A larger headline number does not make a category a better match for your house.

Why the Cat 6 distance figures disagree
Published guidance does not agree on how far Cat 6 can carry 10 Gbps. NETGEAR lists 55 m (180 ft). Fluke Networks lists 35 m for 10GBASE-T. Both sources are credible, and the difference matters if your run is long. For a short patch cable, the gap is irrelevant. For a longer run that must reach 10 Gbps, do not assume Cat 6 will reach that distance in every installation. Choose Cat 6A instead when the requirement is 10GBASE-T across 100 m.

Why a better cable may not make your internet faster
Fluke Networks’ certification guidance draws a distinction between cabling and network standards. Its wording is: “Cabling standards are related to, but not the same as network standards.” In practice, the cable is one component in a chain. The network interfaces at each end, the router or switch between them, and the speed of your internet service all set the limit. If your internet plan is 300 Mbps, a faster cable will not change that number.

Before you buy, check whether the bottleneck is the cable at all. Run a speed test on a wired connection to the router, then compare the result with your plan. If the wired result is close to the plan, the cable is not the constraint. If the wired result is far below the plan and the link speed shows a lower rate than your devices support, inspect the cable, the connector and the port settings.
Installed runs need more than a category label
A cable sold as Cat 6 or Cat 6A does not certify a finished link on its own. Fluke Networks states that a certified installed link needs suitable cable and connecting hardware, correct installation, and a pass on a compliant field tester. If you are planning in-wall wiring, a certification test is the step that confirms the completed link, not the packaging on the cable reel.
Quick Recap
Decision checklist
- Gigabit internet and gigabit devices: keep working Cat 5e, or buy Cat 6 for a new patch cable.
- Multi-gig devices or ISP service above 1 Gbps: use Cat 6 or better, and verify the rate on the equipment before assuming it works.
- New fixed run that must reach 10 Gbps over 100 m: plan for Cat 6A and a certification test.
- Data-center server or switch connections within a 30 m channel: Cat 8 may be appropriate. For home networks, it is not.
