Ethernet cable and which ones to use?

It depends on what kind of Internet speed you currently have. If you don’t know your speed call your provider and or use https://www.speedtest.net/ to find it out. There are a lot of different cables that you can use, you can use Cat5, Cat5E, Cat6, Cat6A, Cat7, Cat7A or Cat8.

Cat82000MHz25Gbps or 40GbpsShielded only

Here’s some background information about these internet cables.
Cat5 is definitely out of date and do not recommend this kind of cable under any circumstances.

Cat5e a consumer-level basic gigabyte cable that does have one drawback, the speed changes frequently.

Cat6 a consumer-level gigabyte cable that does not the drawback that cat5e has and hypothetically supports 10 gig ethernet only if the total length and loss are low enough. Can transfer slower network speeds under 1 gigabyte per second if the cable length is 328 ft., and gigabyte internet the cable length needs to be 180 ft. And as for the 10 gigs hypothetical speed the cord is used to be around 110 to 180 ft.

Cat6A first cable to natively support 10-gig ethernet. Cat6A is mostly used for high-speed data transferring over a long distance of 328 ft. for 10 gigabytes per second.

Cat7 & Cat7A both support 10gig ethernet, have the ability of pair-sharing which makes it possible to use one cable to give power to multiple different devices at the same time which will especially be capable if you want to use a network switch. To use the maximum transfer speed the cable length should be 328 ft. for the 10-gig.

Cat8 the most powerful ethernet cable right now is most ideal for communication in data centers and server rooms where the 25 to 40 gigabytes per second. The cable is overpowered for home networks as most networks don’t have any consumer-level 10 gig internet speed. Most of the time these cables are only 98 ft. in length (but of course will change become longer in the future).

What kind of cable do I use

The kind of cable I use is a mix of the cat6A and cat7 that work with two kinds of network switches.
The cat 7 cables are connected to the main computers and from my Wi-Fi extender to both of the network switches so I know that my computers are getting the full capability of the network speed. And all of the cat6a cables are used for other things like NAS units, smart TV, laptops, game consoles, and a spare desktop.
