Question Dropping ethernet connection

[Belcraig]

HI Guys
I have a x96 Mini wired into my network.
Wire works perfectly fine to begin with and the x96mini can be pinged from another computer on the network.
I'm using kodi to play films from my server to the X96mini.
However after around 10 - 15mins I lose the connection.
The box says it is still connected but it is no longer "pingable" from another computer or from the router.
Play store asks to connect to the internet.

Any suggestions on what could be causing it to drop the connection?
feels to me like it switches off the ethernet port (airplane mode is not on)
the only way I have found of fixing it is a complete reboot,
not something I ant to do every 13 mins of a film?

thanks in advance

try a different ethernet cable

reset the box
try wi-fi

maybe the box is overheating or faulty. RMA the device
