Been there done that with everything I have read with other people submitting the same issue. Newer top of the line router, speakers are 5 to 20 feet from Mesh router. Still same, cutting in and out randomly. Have power cycled, removed the sub and added back in, have reset router (Power Cycle), always seems to come back. Sometimes will go weeks or days with out the cut in/out. But of course it always happens when you have friends over..lol
I’ve read others with direct wiring with Ethernet cable and shutting off wifi to each speaker, and the issue is still there.
