Because of the layout of the house, I needed boosters. Each has a variant of the basic router name but each has the same password. But when I move from one room to another Sonos gets lost, telling me it can't connect to the network because the one that it was setup on is now too weak, and my iPhone is logging into one of the subnetworks (it does that automatically). This is especially important when I move the speaker from the kitchen to the yard. Is there any way to teach Sonos to choose the strongest network?
