Ring Door Bell Not Connecting to Wifi

I have tried everything from reseting the modem several times, reseting the device, created a simple password with no special characters, checked with my internet provider about the ports to make sure the modem allows the door bell device to be accepted, and rerturned then repurchased a new device. Still no luck. At this point I am really frustrrated and walking away from Ring products all togther. This is my last attempt to get this device connected and working. Someone please help.
