Indoor pan/tilt camera disconnected

I have had 2 of these pan/tilt indoor cameras for some time now with no issues, all of a sudden they aren’t connected to my WiFi. Nothing has changed, I have signal; I’ve tried the steps of reconnecting but my network won’t show up. I’ve reset the cameras, tried to set them up with batteries, I removed them from my devices but now can’t get one back. They go through the blue flashing setup light and the voice comes on saying setup mode, I’m able to connect via Bluetooth or WiFi to the camera but my SSID doesn’t show; I’ve reset my router/modem and still same. I don’t know what else can be done?
