Hello, is it essential to ground the 1200 powerline adapters? What solution is there if my power outlets are not grounded? Thank you.

    Hi,
    yes, it allows for a bit more bandwidth since the 1200 Mbps powerline adapters use the ground for MIMO, meaning multiple streams in parallel: a single phase-neutral stream without ground and phase/ground or neutral/ground streams in addition for MIMO.
    So it will work without ground, but not at the full theoretical potential (which will never be reached anyway).

    Thank you for your quick response. But will a 1200 CPL used without a ground connection be more efficient than a 500 or 600 CPL? Thank you in advance.

      No, not more.
      In any case, none of them are efficient, at least compared to a direct Ethernet cable.
      They should only be used in temporary installations.

    Would a powerline adapter (500 or 600) be more efficient in terms of speed than a wired powerline adapter?

      Even less,
      we add the wifi issues to those of the powerline adapters.
      But it still allows adding a remote wifi access point when there's no ethernet wiring for that.
      For wifi, if you want performance and range in residential settings, you need mesh wifi, but it costs a bit more...

    Thank you very much. I know what I have left to do. Best regards.
