I have a sonos ZP and a Player 5 (1st Gen) in one room connected to a TP-Link router. In another room I have a Sonos One connected to a second TP Link router. Both routers are connected via ethernet and the one in the Sonos One room serves as an Access Point with no DHCP. The issue is that the Sonos One keeps disappearing from the system. I have ‘cold’ reset it many times, but it keeps dropping out. The second issue is that whenever I play audio it keeps dropping in and out. Especially when I group all the speakers through the Sonos One. I recently gave it a static IP and it seems to have helped some with the first issue, but the second issue persists.
I just submitted a diagnostics report #1031527086
Hopefully someone can help since I am loosing my sanity over this.
