On my other devices (Android and Apple) the WiFi stays connected to receive incoming WiFi calls, texts, emails, etc. (even while the screen is black/off) When I unlock the Le Pan TC970, the WiFi symbol isn't there and then it returns. Under "settings" the WiFi says "obtaining address" and then connects." I don't see a setting to keep it active so it doesn't sleep. Am I missing something or is this the way the device is? I can get a "keep alive wifi" app to fix this. In a related question, is there no "airplane mode" setting anywhere?
