I have two Sonos systems: one in the main house (composed of a stereo pair of Play:1 speakers, one Sonos One, an additional Play:1, one Play:3, a Sonos Playbar with Sub Gen2, and two Play:1 surround speakers) and one in the second home (composed of three Play:3 speakers and one Play:1). Both systems use a Sonos Boost, and the networks are configured with the same SSID and password so that I automatically connect to the available system.

Until recently, both installations worked properly (even though the new app is a bit slow). However, in the second home I have noticed a marked deterioration in performance: the system has become slower, and there are frequent disconnections—both of the active service and of some speakers.

In an attempt to resolve the issue, I performed a factory reset on some speakers and then tried to re-add the reset speaker. Unfortunately, the process does not complete, and I can no longer see the device in question.

It is true that the network in the second house is rather slow and unstable, but in the past I was always able to easily add newly purchased products—even managing to transfer speakers from the main house to the second home, even if they had been initially set up in the first house.

What has changed? What solutions can I adopt to resolve this issue?
