Hi I have just bought a MID703 android tablet and When I swich on the Wi fi it detects my home network however once I type in the security code it almost inststantly says I'm "not in range" of the network even if I am still standing next to the router. My router is using WPA2 personal. I have also tryed acsseing public wi fi and had the same result. All my other networked devices like my computer and phone connect fine. Is this a settings or software problem or do I have a faulty tablet?
