Yes, when I said in my original post that I had good signaling meant the dot and two curved lines. No I am not putting it in sleep mode, when I said I shut it off I mean totally off.
I'll try and be clear on my issue. When first started all works normally, then after a period of time or after it has been in sleep mode I can't access internet based apps. The little whatchmacallit spins and spins and nothing happens or I'll get a you must be connected to the Internet notice or unable to load type of note. Again this is at home with full signal strength.
