Sky mini box not working,

[Hmss]

My sky mini box was working fine then last night wouldn't turn on, I made sure sky Q was on downstairs as it needs that on to connect. Still not working. I unplugged the box upstairs then plugged back in, and it wouldn't turn on using remote but the tv did with same remote so not batteries. 
the sky box I turned on from the box and not it says press the dot button to connect via WIFI. But the remote won't do anything on the sky box. I've changed batteries and still nothing
