The S1 app which is used for the old Play 5 gen 1 says "unable to connect to Sonos". I think it's to do with the TP link deco M5 mesh system I installed recently. I can reconnect by switching the router off and on, but it never lasts and the next time I open the app the speaker is gone again.
If someone could help in step by step idiot proof terms I'd be eternally grateful. TIA
