Live View: Activating Device

Hi I just installed a Ring Pro, and discovered that Live View rarely connects... maybe 1 in 10 times. It usually just gets stuck on "Activating Device" If it does connect, it lasts for just a few seconds. Are there any methods to fix this? I have tried access Live View through the app on the same Wifi as the Ring, and through cell connection. This issue effectively disables the key feature of the Ring device - being able to talk to someone at the door through your phone. I don't think it's a Wifi connection problem. Device Health shows RSSI-49. The device consistently uploads videos when motion is detected, though the video clips do have a audio popping sound problem (different post.) I am using a Arris BGW210 modem/router combo. Thank you.
