Recption Issues

I have had a ring at my home for a few months now and enjoy it albeit one thing. From time to time it does the following; 1. it does not connect so that I can view it live when triggered 2. it doesn't show anything or it shows a still picture from earlier. I am thinking that I might need to get the extender or change the speed of my internet connection for the wifi signal to connect better but I don't have a poor wifi connection message. I have a split level house with cameras by the front door, living room, laundry room, and garage. Any help or suggestions would be appreciated. Thanks, TD
