Hello,

I have a wi-fi repeater that is closer to my Argus 2 and therefore it has a stronger wi-fi signal at the camera location.
I've tried to change the camera wi-fi connection from the original router signal to the repeater (different SSID's) but everytime I do it the camera just desapears from my network and I have to start the setup all over again (camera reset). I've even tried to first stablish the connection to the repeater signal but then the camera fails to find the router unabling to setup the wi-fi to the repeater signal.

Is this a limitation? Can it be fixed?

Yes. My Argus 2 does the same. It catches a car passing by but many times, when the car is fast enough, the camera does not record it on time.
