CPL Wifi, one or two sockets?

Hello :)

CPL Wifi, one socket or two?

Good evening everyone

Can anyone tell me if it's possible to run a powerline network with just one socket?
Normally there should be one near the box and another in a different room...

Why this question?
The brand Devolo offers a model with just one socket, so that should be enough.

Attached is a link from Les Numériques with a test report; it doesn't mention two devices...

https://www.lesnumeriques.com/adaptateur-cpl/devolo-dlan-1200-wifi-ac-p21603/test.html

Devolo also sells models with 2 devices, I don't quite understand.

Thanks ;)

    Good evening,
    You need to buy the starter kit consisting of two plugs: a simple PLC that connects to the box and another WiFi plug that you install where you want to provide WiFi, the plugs sold individually are for those who have already purchased the starter kit.

    You understand well that if your box is not connected to a first PLC adapter, the second one, if it is located in a different room than the box, will not be powered. See this page. Of course, you can only connect one socket to the box, but there will be the WiFi network of both the box and the adapter in the same room, which seems pointless to me.

    Hello

    I didn't quite understand your request.
    The powerline communication (PLC) is about transmitting a signal through the electrical circuit, so you need at least 2 modules. One that connects to the box and another where you want to "retrieve" the network.

    So you definitely need two power outlets.
    Then there are modules with 2 network ports on the module, which allows you to connect two devices directly via network cable.

    There are also modules with an electrical socket INSIDE the module, which allows you to have the PLC module AND plug in an electrical device when you only have one power outlet available.
    Indeed, you should never plug a PLC into a power strip, as it may cause interference.

    Thank you for your response. ;)

    But then why doesn't the Numériques test bench on the Devolo dlan 1200 + ac mention this problem?

    It seems to only talk about a single socket...

    Regarding a kit with 2 sockets, the same brand offers a kit of 2 sockets that is much cheaper than the single device I mentioned earlier, tested by Numériques...

      One kit is not like another; quality and, above all, speed will make the difference in price.
      There is no "problem," no reason to mention it. It's the very principle of the PLC. It's like saying you want to buy a television but no one mentions the digital decoder that goes with it. It’s obvious.

    Yes, thank you ;)

    Attached are 2 very similar models at different prices with their specifications.
    ->But one is "wifi", the other one is NOT...:(
    So it's for an ethernet network, does it work as well as wifi?
    What do you recommend?

      Hi,
      you're being annoying now...
      Gigabit Ethernet will always work better than Wi-Fi, understood?
      Do you need wireless or not?
      If you want to drive the point home, nothing beats an Ethernet cable, except for a mobile device.

    Sorry, I'm a novice in this field, I'm discovering... it's not simple.

    You talk about "wireless": there's also Powerline (CPL) in this area.
    And even CPL and WiFi like the model mentioned in the first post (Devolo Dlan 1200 Wifi ac)

    In this specific case, if I refer to what you say (ethernet is better than wifi), what should I choose if we have the choice this time between CPL (and not Ethernet) or WiFi like with this model?
    Will CPL still be better than WiFi?
    I'm asking the question because this CPL/WiFi model is more expensive than the one that only does CPL, and if CPL is better than WiFi, why opt for a more expensive mixed model?
    Once again, I'm just starting out...

      either you have a device with an Ethernet connection, in which case you take a powerline Ethernet adapter only, or you have devices without Ethernet and then you need to take a powerline/wifi adapter.
      Powerline is not a competitor to wifi which concerns wireless; powerline is wired, in fact quite thick.
      Powerline competes with Ethernet and doesn't stand a chance in that game.

      They should have written CPL+Wifi,
      these products mix the wifi access point and the CPL modem.
      There are also wifi access points without CPL modems, there are many of them.
      Clearly, not explaining this
      leads to confusion among beginners like you, and it's a hassle to catch up afterwards.
      That said, CPL (Power Line Communication) is also radio... over electrical wires.
      But wifi is real radio, with antennas, even if they are hidden.
