What are you going to do if your lovely router that you just bought and hooked up your whole network to ran out of ports?

Let’s say I have many, many computers in my house, or in my office, and I connected all of the ports that I have here. Most routers will have four ports on them, so I have connected three computers and a printer. But suddenly I wanted to buy another computer. So, that’s what the switch is for. A switch is basically kind of like a network surge protector. Just think about it this way. You plug in one output to your router, and the other ones will just split up that connection, to give you more hookups. This is called a four port switch, which will mean it will have actually five ports – one which will be uplink. It will send the signal back to the router – and the other four will split it up for four computers. Switches come in many sizes. They can come in four port size A ports, 16, 32, even 64. And of course, they have much larger more industrial switches for big industrial settings. And they also have different speeds to them. And when I say speed, I’m basically talking about the speed of the port. The basic speed is 10 megabit per second; then you have 100 megabit, which is pretty much the standard nowadays. And today, we also have faster switches which are gigabits. So you have 1,000 megabits per second. If you buy a gigabit switch, it’s also wise to make sure your computer has a gigabit Ethernet port, and also that your router has a gigabit Ethernet port, otherwise you’re not really thinking that that would do it.

So, if you have way to many computers for your router to handle, an Ethernet switch is definitely what you need.

I just bought a house that was wired for cable/internet. In a closet there is a large cabinet with tv cables and ethernet cables and a place to hook up my modem/router…whatever.  In one room / my office there is one ethernet port. Can I run a ethernet cable to a switch in that room and then run additional ethernet cables to my xbox, playstation, computer?

ProAzzazzin says:

say I had the router upstairs and had a 50′ cable running under the floor to down stairs could I plug the cable into that then buy 3 new cables on for my pc and another for my ps4 and one to the Xbox 1

pencaps100 says:

Yes, I do know. Sounded like you were asking what he was saying. He was saying “megabits”. That’s the standard term for transfer speed.

pranit kashikar says:

I have enter switch can it also be used…

Good O'Rusty says:

Do you have to have a router with the switch. I have a cable modem and I want to connect two computers to the internet. I bought a switch thinking that would be enough. I can get internet with one of the computers but as long as both are connected to the switch at the same time only one of the computers actually has internet access. The other simply says local only and that its connected to unidentified network.

hillmanant says:

Great explanation, simple and to the point, thanks much.

yzchenwei says:

that’s right. And the speed of the modem is 10/100 megaBYTES not megabits.

boobytrap5000 says:

if we are on the internet now then why would we need to know this

Juan Pablo Sanchez says:

can  NETGEAR 5 Port Gigabit  Switch be plug to 240 volt

yzchenwei says:

Lol, if you said so. Try to have 100 megabits transfer rate out of a 100MB router. Good luck.

Hi, there’s a key point you glossed right over and nobody else even mentions on this netgear switch. Can you clarify here for me. First off, it’s a 5-port switch, not a 4-port switch as you described (model GS105). Right now I’m debating between the 5-port and the 8-port version (GS105 or GS108). This 5-port switch has 1 port “seemingly” separated off from the other 4, but the netgear manuals make no mention of it as a special port. You imply it’s for the connection back to the router and seem to point to it while you’re saying it. And in another video of yours, that’s the port you specifically use back to the router – as if it’s special. But other videos say it’s just 5 general ports and you connect the router to any port. Is there really something special about that 5th port. The netgear manual says nothing special about that port. Please help! Nobody else has even noticed this apparently!
