I have a strange scenario, I have a Wyze Cam v3 that connects when I am working on it at my desk, but when I bring it to its actual location on the other side of the building it will just blink between red and blue, but I have a full wifi signal on my other devices. The camera has been at the location and working seamlessly for the last 6 months or so, then randomly went offline last week.
The only difference I can find is that it is using a different power cable then the one at my desk. The one at my desk is the standard version and the one in the location is the same only longer to reach the area. The camera is getting power because it has turned on, but other than the cable difference I dont see why it wouldn’t work.
The cable is a 15 foot cable I got from Amazon, but I just set up another camera in the location with the same power cord and it works as usual. I even plugged this camera into another outlet nearby to see if it was a wifi issue, but it worked fine. It seems to be this one location, camera, and power cable.
Have you tried a different power supply? One of the things impacted when a power supply isn’t putting out enough power is wifi. Any USB power brick with at least 1000mA/1A output will work.
It may be enough power when used at a short distance where a weak signal is enough, but not for a further distance. Just worth trying if you haven’t already.
Barring that I’d say the wifi chipset is burning out, not exactly uncommon for IOT devices, they use pretty cheap chipsets and don’t have very good cooling, heat is the enemy with these things.
Heck even just for testing use an AC extension cord and the stock cable just to see if maybe the cable has somehow started going bad internally (wires breaking down or connections corroding etc).
If a new power brick and the stock cable works, then try the long cable again. If that doesn’t work then try the stock power brick with the stock cable. That should narrow down and tell you exactly what part is dead (and it may be the camera).
