Can I use one ethernet cable to give internet to two devices?

my current set up:




what i want or what i am trying to get:



so how exactly can i use that one ethernet cable to give my PC and my switch a wired connection? what would i have to purchase?

i dont want to use 2 differnt ethernet cables because I already have a 50 foot cord from the living room all the way into my room so I just want to use that one single ethernet cable.


the switch HAS to have a ethernet to USB to have a wired connection so keep that in mind. thanks for all the help.

Gigabit Ethernet uses all 4 pairs. So if you use splitters your Switch and PC would only be able to send/receive at 100Mbps instead of the full 1000Mbps. Depending on your LAN usage this may or may not be a problem.

For $15 I would just buy a Gigabit switch and not mess with splitters.

But it looks like the OP wants to connect the Nintendo to the PC over USB, and share the PC's LAN connection, which is not possible with any devices I've seen.

Code:

[Nintendo]=[USB<->Ethernet]---------(CAT5)---------[Switch]-------(CAT5)------[PC]
                                                      |
                                                      |
                                                    (CAT5)
                                                      |
                                                      |
                                                   [Router]

Hi there

@McSweg

probably the simplest way is to use a CHEAP 4 / 5 port switch and then connect one port on to the switch to say a wifi extender / router if near enough or whatever.

Use one of the ports on the switch to connect to wifi extender, and other ports for your input devices -- USB-->LAN works fine so that's not a problem for the Nintendo or whatever.



This is actually the easiest way also to connect several computers via ethernet to a decent wifi extender -- the switch will give much better network throughput than using 4 separate ports into the wifi extender direct from the computers.

A decent wifi extender this way will give over 115 MB/s (not Mb/s) over a lan -- quite a decent speed for file xfers etc etc and easily sufficient for any sort of media streaming.

I use a Netgear Nighthawk 4 port wifi extender -- has 3 antennae on it -- and a cheap netgear 4 port switch. My NAS only has ethernet and it's a long way (around 150 metres) from the router so the Computer device-->LAN-->switch-->wifi extender-->router works a treat.

also good for connecting laptops etc as the lan method is usually better than the internal wifi cards on some domestic / consumer grade machines.

Plug the device and the other machine into the switch (2 LAN's) and the switch into wifi extender. USB-->LAN on the ist device is fine that should work properly.

Buy a 5 port Gigabit switch for your room. Something like this for $35. Amazon.com: NETGEAR 5-Port Gigabit Ethernet Unmanaged Switch, Sturdy Metal, Desktop, Plug-and-Play, ProSAFE Lifetime Protection (GS105NA): Electronics

Plug in the 50ft cable that is already running into your room into that switch. Then buy 2 short lengths of cables and plug 1 into your PC and plug 1 into your USB to ethernet adapter for your switch
