After factory reset Ring-xxxx network not broadcasting

Setup: 16V 30VA Transformer (new)By-passed old chime using Power Kit V218 gauge wireOn inital install Ring Pro connected to my wifi (2.5GHz) correctly . All worked as expected. Voltage was Good (4058 mV) RSSI -56. Over night Ring Pro lost connection and would not reconnect. I tried Reconnecting to Wi-fi then a factory reset. All attempts resulted in the Ring-xxxx network not being broadcasted. factory reset I held the reset up to 60 secs, the light goes off then the blue light will come on in about 30 seconds. Once the dull white light turns on I go into setup. I checked the voltage and it is 17.6 V when Ring Pro is on. This is the second Ring Pro the first one did the same thing after 2 weeks. How can I verify that the Ring Pro actually reset to factory settings?Thanks
