As a Wi-Fi device, they are subject to the issues we always face with Wi-Fi devices. That being said, mine stays connected to my Wi-Fi without trouble. I have Ruckus right now. The delay is between the time you receive a notification, tap to open the app, and wait for it to connect.

However, if you want me to help you, you need to provide more information. Do you want to set this up as a recording device, that records everything that goes on at the front door? If that is the case then you need to install an NVR system with cameras, where the hard drive is spinning all the time. That is my opinion. You will not video the guy that has made off with your Amazon box in a 5 second grab n go. I believe the Ring and others like us are for casual conversations at the front door.
