I bought my first Sonos device last year, the Roam. Using it as a bluetooth speaker is fine and I love the sound and portability, but oh boy do I hate the experience of trying to use Sonos services over wifi.

Nine times out of ten, perhaps even more often, the iOS app says it can't connect and "let's fix it". If I go through the slow reconnection wizard it invariably ends up telling me to reboot my router(!?). I learned to either switch the Roam on/off a bunch of times, or kill and restart the app a bunch of times, before the app eventually decides yes, it can find the device ... only to then fail again when half hour later I want to add something else to the queue or switch station.
