Ring drops wifi after each new replacement

I've had a Ring Pro for 3 years. Then one day it just stopped working. Support was fantastic and sent me a replacement. After 5 minutes working, it stopped. Called support. Ran through everything. They sent me another replacement. I have honestly lost count now, but I think I broke a world record. Support has sent me 8 or 9 replacements. Every single one of them failed with internet conection shortly after set up. Each time I'd get a replacement, I'd eventually be on the phone with support. With Level Two Support. We've gone through all the protocals. From hard reset to reconfiguring the modem. Apparently, every Pro I recieved had different issues. Each time I'd get a replacement, I'd wait until I had the patience to be on the phone again. I have now recieved the latest replacement. I am too afraid to do the set up again, knowing 99.9% it will once again fail. I'm at my wits end. I have many wifi devices in my home. Would that affect connection?? What the heck is going on!!!?? Thanks guys....
