Question about Netgear Orbi RBK50 set

In my case, the modem is on the 2nd floor. But I need internet on the ground floor, 1st floor and 2nd floor. I first had the Devolo Ethernet-over-Power and a stronger AccessPoint on the 1st floor. Since the walls and ceilings hardly let any signal through, this is not enough. In addition, the Devolo Ethernet-over-Power adapters are ok for normal surfing, but as soon as you have streams on several devices, it's a disaster (delays, throughput problems, stability and reliability rather poor).

Since switching to Orbi, I've had no throughput, latency or reception problems on any floor. It's a great thing!

I have the same set-up: Internet modem plus NAS and network printer in the basement. Via ORBI, the connection to the ground floor and upper floor works without problems (concrete ceilings, underfloor heating...poison for any WIFI). Mostly almost 100% of the modem performance upstairs (500MBits/50MBits). Placement of satellites was a bit of try-and-error until it worked really well. But already first try was 10 better than Powerline or old router (Nighthawk X4S).

I confirm the above statements, also works in the basement.

I confirm that with an Orbi on each floor, concrete ceilings have no effect.

We also have strong concrete walls horizontally and finally I have network everywhere. A friend also uses rs from the basement and has had reception since then too. I am satisfied!
