My daughters Galaxy Tab 4 is having a problem since yesterday. The Wi Fi comes and goes from the tablet, I can even be next to the router and if the tablet start scanning it wont appear. I checked and it doesn't have an IP Address but it has a MAC Address. How can I solved this, my daughter is just crying because she cant use her tab. I tried looking for the IP at http://192.168.1.1 but appear that the page its not available. Help pleaseeeee, I already restore the tablet, also try the factory data reset and nothing. I'll appreciate all the help that you guys can give me.
