Thanks, so this is all I need.
Maybe I did not word the second part of my question properly. I want this for my elderly parents, so it needs to be simple to setup. They use a Telkom 4g router with ethernet.
Their house is funny, there is wall that blocks 99% wifi signals. I could not get clients to reliability connect through it using a 500mw Mikrotik router with a 11db omni.
I've had some bad experience with plc at my house, some wall sockets would not connect at all. It turns out the live and neutral wires were reversed inside the plug. Other plugs worked, but not stable due to old rusty wiring. Other plugs worked perfectly fine. I suspect similar wiring issues at my parents house.
Being a hybrid system, does it only use plc for backhaul between the units or can it fail over to wifi for backhaul? I want the best possible chance of success.
