Arlo Pro cameras dropping offline recently

[Cowcorner]

Having a recent issue with 2 of 4 cameras dropping offline, I have changed cameras and positions and batteries and base unit locations to no avail, wondering if there has been an update lately that might be afffecting it or wether I have a faulty camera. All my cameras have battery and power so that isnt the issue. One camera would be 20m from base unit and the other is only 2m so im thinking its not distance. The issue would be only the past two weeks at most and I have never had an issue before.

Also when I resync the camera it is missing from the base modes for my recording settings, seems really strange that it is al of a sudden happening after many months of little issues.

Verify that all devices have the latest firmware. Is it possible that a device that uses 2.4GHz has recently been moved someplace near the base?  If not, a factory reset may or may not help.
