Ring Device with New Fiber Optic internet connection

I purchased my Ring device December 2020, and have had no issues until my internet went to fiber optics a few months ago. Since then, I have tried to reconnect my Ring device to my internet/modem, and it is unable to do so. I am wondering if the new fiber optic internet speed is now incompatible with the Ring device due to its age. If yes, is there a way that Ring will give a discount for the purchase of a new one. Any help would be greatly appreciated.
