Panoramic wifi

So a few months ago we upgraded to Coz panoramic wifi because we could not get a good signal to our Ring doorbell. When the guy came to install he said oh this is big house. Um our house is just over 1400sf so not big by any means. We had it installed in the room where old modem was which is actually furthest from the front door. But didn't see a difference for the door bell , so we moved it to the center of the house, and but now its as bad as it ever was. So we are paying more for panoramic for what purpose?
