Hi ... can anyone help? Just bought this 3Q tablet, have sent it back to the service people already, they tested it, said all okay, and sent it back to me. When I sent it back, it wouldn't even turn on either, but they said it turned on first time. It worked fine for a day then won't connect to the internet, even though it says on the tablet that wifi is connected. Nothing wrong with my wifi connection, as the laptop works fine. What can I try? Or should I just send it back again? Costing me for postage each time, though.
