Are the Orbi's connected over wi-fi or Ethernet backhaul? If you're creating your mesh wirelessly, then you loose quite a bit of bandwith for your devices. I don't know the specifics of the Orbi setup, but typically the 5Ghz band might be used to connect the mesh nodes, which only leaves the 2.4Ghz bands for device connections. I use an Asus AiMesh network and all my access points are wired for this reason - I do appreciate that not everyone is prepared to flood wire their house with CAT5e (it was a while ago!).
Over wi-fi. I want to remove any kind of as much as possible. That’s the reason why I get B&W Formation Duo.
B&W formation duo can only connect to 2.4GHz. I do not want to wire anything since I figure out the solution.
The weird thing about my problem above is, “technically, according to B&W technicians” even though someone uses streaming device next you, this should not affect the listening quality of spakers. B&W’s wireless network (this product line is meant for multi-room entertaining system, like sonos) should secure enough to stream(airplay 2) music without problems. But they also mentioned in case of big music files it might happen.
So, I got the YES and NO as the answer. -.- Anyway, I found the unique solution now, and I need to send kids to school.
