It’s worth noting that my Wi-Fi network is based on a Linksys 802.11ac router that’s connected to a Linksys Wi-Fi range extender located about 10 feet from the Ring doorbell (albeit separated by a thick exterior wall). I spent a significant amount of time with Ring’s operations director to fix connectivity problems in the early stages of testing, but even this wasn’t enough to solve all the performance issues. My Wi-Fi is dual-band, supporting both 2.4- and 5GHz, but Ring uses the 2.4GHz band via 802.11b/g/n support.

3 - If you do not answer the alert fast enough, you are locked out-- even though someone is standing at your front door. You cannot "turn on" the camera from your phone or tablet. If someone is there and you do not have an "ACCEPT" button on the screen, there is just no way to see or talk to them. This is obviously a software flaw. You should always be able to "wake" a camera remotely and talk to a person at your front door. Or maybe you just want to see the view outside your front door. You should be able to access the camera / microphone and enjoy your front yard.
