Intermittent sound

more often than not my mini stops every 8-10 seconds then plays for 8-10 seconds. my second unit doesn’t work at all and I get a weak signal notice. It’s about 16’ from the router. I’m clocking between 50 and 100 mps for internet speed
whats happening?

Try rebooting your router and when it’s back online, reboot both minis. Try 5ghz only and set preferred DNSon under their network setting in the wiim app
