Spot Light camera will not load

I just purchased a spot light camera and mounted it to on the side of our garage. Camera loaded fine during setup process approximately a foot from where it was installed. We have Xfinity 1Gbps internet and our modem is on a shelf in our garage approximately 15 ft from the camera. Our ring doorbell has always loaded fine and still does. This camera will not work since I’ve finished installing it. It has an RSSI of -45. Our doorbell has -52 and loads instantly. Idk what to do. How do I fix this? Did I get a bad camera?
