Thanks for replying, as far as I can tell the Hub isn't actually losing the connection, I'm aware of the light and I never see it.
I noticed last night now, whereas previously I said all devices, if I have some kind of streaming on my iPad using the wifi it does not drop connection, whilst I look at my PC or someone elses laptop sat right next to it dropping connection every minute. I watched an entire football match on my ipad with no issues. I could go home tonight and it could drop on all devices, but last night that was the case.
So the connection is still there, but for some reason PC's or laptops lose it, ethernet or wireless; but mobile devices are still accessing it just fine and I haven't seen the light on the hub at all. I must admit I haven't paid explicit attention to the hub light colour, but my iPad absolutely does not lose connection even whilst watching things live.
Edit: Also should note the connection seems fine in the mornings, only gets bad at night! "Prime times"
Further edit: Just got home and checked it out, light is going orange every so often on the hub and likely causing the PC disconnects.... so.. faulty hub?
