Have to rest my Panoramic router weekly to re-connect Ring Security Cameras

I have 2 Ring Spotlight Security Cameras and a Ring Doorbell camera. Every week I have to reset my Cox Panoramic router to reconnect my wireless security cameras. I have "Giga-blast" package through Cox so bandwidth shouldn't be an issue. Does anyone have same issue or recommendation for fix. 

Also, how do I login to my Panoramic modem/router?

Thanks
