I purchased a generic Chinese android tablet that connects fine to my home wifi modem but will not connect to my smartphone hot spot. I know the phone hot spot works because others have connected tablets and smartphones to it. I was really hoping to use the smartphone as a hot spot for the tablet because the smartphone screen is too small for using as such. The tablet shows that it is connected but any browser I attempt to use gives a message that the device is not connected to the internet. Both the tablet and the smartphone use wpa2 security. Another question I would ask is if a wifi app downloaded from Google Play store would help this situation? The tablet has android 4.4.1 installed.
