I recently bought a used sonos playbar and sub. Worked well at sellers place and looks in good condition. Now I factory reset playbar and sub and trying to connect to my wireless but is not happening. It connected for like 15 minutes played well then sonos controller couldn't find any system. Speakers sound good but the connectivity and software sucks. Have already lost so many hours in just connecting and setting up. Now again I am trying to connect but connot add playbar...even if I finally able to add and sonos says you can disconnect and place in desired location, when I disconnect- move-reconnect, sonos controller says cannot connect. My wifi is strong and connects TV and such well in my room. Any help please?
