Ring Video Doorbell 2 not working with TP-Link Deco M9 plus

Hi @Felix63. Does your wifi password contain any special characters? Sometimes the special characters in the password has had some neighbors run into a concern with the device not connecting. Additionally, you may need certain ports and protocols opened on your router for the device to connect. You can learn more about that in our Ring Help Center Article here. If you still run into this concern, please reach out to our support team here. Let me know how it goes!
