I’ve had mine for about 2 years and have nearly zero issues. Began using it wirelessly, but over the last few months wired via a Wi-Fi router extender.
Granted, using wireless it could be quirky on setup, or reconnect, but almost always solid without any dropouts. Connected via ethernet cable directly, almost all issues are nonexistent.
Seems odd to me this is happening with two units, and have to think there is an issue elsewhere.
Great sound for the $
