Both ArloQ's are offline

I've power cycled them. Still offline.

My router rebooted but I've done this before and the cameras came back. The WiFi is active and signal is strong.

A security monitoring camera even if not professional grade is pretty crap if the software is buggy enough to not hold a resilient wifi connection.

Since this isn't a widespread problem, it sounds like it's something specific to your environment.  It could be router- or camera-related.  The fact that all your cameras seem to have this issue makes me suspect the router.  However, another issue may be power - is it reliable in your home?  If not, a UPS on your network equipment (and maybe your cameras) may be useful to ensure they don't go down due to glitches or outages.  Some enterprising folks have used a large USB battery between the power supply and the camera to handle this.  You just need to ensure that the specific battery will charge at the same time as supplying power to the camera.  I haven't tried this so can't offer a suggested battery.
