Hi @Jon_M84, thanks for your post - sorry to hear you've been having this problem.
I've taken a look from here using your forum details and it looks like there's some issues with the hub's power levels. Can you try factory-resetting the hub and let us know when that's been done? If that doesn't help we can book an engineer to check things over.
Hi Tom_F, Already tried this when I called customer services the first time it happened. They said all is looking OK, have even had an engineer out before to look at the line and slow speeds (which seems to be resolved now). I'm on the Hub 4 if that makes any difference?
@Jon_M84 Thanks, checking again it's the same as before - I would usually book a tech-visit straight away when I see flags like what I'm seeing on your hub to be honest, I only haven't because from what you've said everything else service-wise appears to be fine.
Possibly the power-levels are what is causing the hub to lose it's settings when powered down? Seems odd to me but I'd be happy to arrange another engineer visit if that's suitable for you.
