It sounds like these concerns may all be slightly different in nature. @Neighborfriendly51 if your device is exhibiting unusual behavior with the chime kit and buzzing, the connection may be power related.
@sailingcal21 as rebooting the router/ network seemed to resolve your connection concern, it may be network related settings, or router features.
As there seem to be quite a few variables here, the most efficient solution would be to contact our support team for isolated and in depth troubleshooting. Feel free to update us on the results!
