Ring getting kicked off WiFi.

This has been frustrating. At least once a week, one or more of my 3 doorbells disconnects from WiFi. Which means if I forget to check my doorbell for a day or two, it hasn’t been recording. Then re start my modem and they connect again. I have no idea why this happens. I’ve searched and haven’t seen any other complaints about the same issue. I have a new modem. I have a separate 2.4 ghz channel set up for the 3 Rings so they dont jump to the 5.0 and disconnect, this was suggested by Ring. Is there a chance my modem is doing a reboot or something that disconnects one or more of the doorbells? They don’t all turn off at the same time. Sometimes it’s 1, sometimes it’s 2. I’m just frustrated by it. Any ideas?
