So i have this strange issue on a almost vanilla pi 3 ( using raspbian). apart from removing the pi user and making my own user and giving it a static wifi address, not really done much else.
So i've read the pi can't necessarily "turn off" by itself, but what im seeing is effectively a black screen after ~10 mins or so standby, when i plug the hdmi in. As soon as i plug in a keyboard i can see the tty login promt, only after which i can ssh and ping to pi. After a while however ,the problem cycles.
the router states that the pi is connected but it remains un-ping-able, so i assume its just the router not updating the list of connected devices.
duration between these states varies and im not sure if it errors where i can find these logs.
Sorry for not providing much in terms of information but i kind of feel like im not understanding something here.
