Disc 3 connects to disc 2 with excellent connection.
Disc 2 connects to disc 1 with 'good' connection only and suggestion for improvement.
It works OK.
However, devices in the Lounge connect to disc 3 upstairs, even though they are much closer to the disc in the same room. Does anyone know whether a disc is chosen on the basis of its onward signal strength? If so, then the lounge devices are choosing 3 rather than 2 because it has an 'excellent' connection. However, the internet connection from disc 3 is via disc 2 and the only 'good' connection to disc 1. It would be more efficient/faster if they connected to disc 2.
