Using an RJ45 splitter

Solved
ThonyJV -  
Hello,
I have a RJ45 socket in my room that is connected to a computer. I would also like to use Ethernet on my PS4 and my Nintendo Switch. If I buy this kind of equipment, will I be able to connect all three devices, or do I need to do something else?
Thank you in advance

    Hello,

    On this equipment, only one connected device works at a time.

    For the same price, you can get a switch and all your devices will be connected: https://www.amazon.fr/dp/B009TZE41I/ref=psdc_2908498031_t2_B00J3XIAH0

      Thank you for your response, but I am asking the same question as above: how does Ethernet work if it's a power outlet?

      @ThonyJVThere is a power supply, an Ethernet cable needs to be connected to the input from the wall socket, and the 4 other ports are outputs to connect devices.

    Hi,

    Neither of the two. A splitter needs to be split on both sides of the cable.

    In your case, you need an RJ45 switch.

    You connect your RJ45 cable as input with Ethernet, and then you connect your devices with cables to power them.

      Alright, so all my devices will work solely with the switch? How does it work in terms of connection (divided or not...?)
      Thanks for your reply :)

      @ThonyJVIf the switch supports 100Mbps and is connected at 100Mbps, you can push up to 100Mbps peak beyond the LAN. More on the switch itself.

      But 100Mbps is sufficient, although ideally today Gigabit switches are recommended.

      Okay thanks, anyway I rarely use all three at the same time, so once it's turned off I guess the connection isn't drawn. I’ll ask you the same question I asked in the other reply: why does it need a power supply input and not just from the RJ45? How does the connection go through?

      @ThonyJVNo,

      It requires a power supply AND an RJ45 input (on port 1 of the switch, typically).
