I'm trying to determine if all the tablets out of China have problems with WiFi. I have the Pipo U2 and it doest have good WiFi performance, constantly dropping the connection. I'm new to Android and I've only had my tablet a few weeks. I've seen a few other complaints on the web and I'm trying to figure out if some, most or all of these tablets have this issue? Is it a certain manufacturer or certain models or even a certain chip set?
Can current tablet owners please comment? My wife his an iPad and a Kindel fire HD, we both have iphones and all those devices work fine with regard to WiFi all over our house. My android tablet won't work if you stray very far from the router (tried 2 different routers)
