Ring Pro Doorbell not staying connected to the WiFi Network

I’m having a problem with the Ring Pro Doorbell staying connected to the WiFi. After I factory reset the Ring Pro, I can connect to the WiFi again. After about 10 minutes, the Ring Pro is offline again. I’ve reset the doorbell multiple times, and this is the same result. Also, I’ve restarted my router, and that had no effect on reconnecting the doorbell. I disconnected the power from the doorbell multiple times, and the results are always the same it’s offline in about ten minutes. The transformer voltage is good, and the last reported signal strength was RSSI-34. The Ring has been connected to our WiFi since December 2019, and there have never been any issues until August 28, 2021. The WiFi issue is only the Ring Doorbell. My other devises connected to the WiFi are not having any problems. Any help would be appreciated.
