Keypads loosing connections on regular basis

Recently, I have been experiencing an issue with Ring Alarm Keypads losing their connection to the base. I have one system with three Keypads that has been fine for 9 months. Now all three will go offline at nearly the same time. I can reset using the APP and they will be fine for hours or a couple of days, then drop offline again. I have five other systems and each is experiencing the same issue!! This tells me it is definitely an issue with the Ring system and most likely a software issue.
