So after nearly a week of this mine is going back (16gb wifi only model purchased from apples UK online store) they will come and pick it up sometime soon.
In the meantime I've been out and purchased a new one from currys and IT'S JUST THE SAME
Doesn't matter how many bars are lit it just drops the connection so even with a full fan it can't get wifi HOWEVER if I lay it down on its back it works just fine prop it up vertical (not touching it) and it fails again
I did try turning my router on its side but the iPad still only works on its back
I have two broadband connections and two routers. Exactly the same on both I love this device but it's useless to me if I can only use it in he same room as my routers. Bah humbug
