The Wi-Fi connected discs will connect to the best disc based on signal strength and number of Wi-Fi links between it and the primary disc - so sometimes they connect via another disc and sometimes direct to the primary disc, depending on your environment.
I have a few additional questions on this subject, I’m hoping you may be able to help.
1 - Is there a way to see how the discs have connected?
2 - Does the network map on settings show how the discs are connecting? Or does this always show them as being connected directly to the master disc?
3 - Do the discs change what disc they connect to on real time? For example if I move a disc will it automatically determine the best disc to connect to and update? Or is it determined at setup when selecting the disc location?
I am asking as in my case I have 3 discs in the ground floor, the master disc and discs 1 and 2.
Disc 2 is a couple of rooms from the master disc, and Disc 4 is located on the first floor directly above Disc 2.
So I would expect Disc 4 to connect to Disc 2, as it is ouch closer to it than it is to the master disc. But the network map makes it look like it is connecting to the master disc.
