Ring Pro disconnects from wifi after ringing

My ring pro will disconnect from wifi. It will be working fine. Good power and wifi per the device health. I will ring the doorbell to test it. It rings the bell and app. Then it disconnects. After a bit, I can connect again. Everything will look good, then I press the bell. Disconnects. After checking everything I could think to check and going through setup again, I bought a new ring pro. Connected it in the same location to the same router and bell (after removing the old one) and it works fine. This leads me to conclude that the old ring pro is broken. But before I throw away a $200 device, I want to see if it can be salvaged / made to work properly. The one I replaced is about 4 or 5 years old and used to work just fine until about a month ago. Is 4-5 year just the life expectancy of this device? I should note that I live in MN and it gets cold here, though the highs have been in the 30's when it quit working.
