I have Sonos play 5 speakers ( first generation I think) in a pair with a sub. They are all operated wirelessly, but I have a bridge plugged directly into my network with Ethernet. All have been working fine for several years now, but recently I have begun having issues with the stereo pair and sub. They play fine for five minutes or so, but then the sound from one speaker drops out entirely and the others are low and muffled. After about ten seconds or so everything starts playing fine again. It’s quite annoying. I have a tp-link AX5400 Wi-Fi 6 router running both 2.4ghz and 5ghz. The speakers are less than 10m away from my router and bridge with no walls between them.
