I have not yet mounted my doorbell outside. At the moment it and my tablet w/app are by my side - in the same room as my (very nice) router. I am currently downloading a file from the internet. Just for kicks I pressed the ring button (two trials actually) and it took maybe 30 seconds for the event to be processed by my tablet.
The download is sucking up my bandwidth and depriving the ring device its turn.
I’ve never had to play with QoS before - but that might be a solution. Also - I may need to tweak /limit bandwidth on the router as well. I do happen to have 2 routers in the house but I would hate to have to worry about who was doing what in the house on which network if I want to hear the doorbell ring.
Has Ring (the company) given any thought to this situation ?
