I bought an android tablet . It is connected to the wifi and I was able to use it 3 times on the internet. Now it says excellent signal but I can't get onto the internet. 2 other devices are Working Ok. have checked date. time and password and all OK Even gone back to factory mode. It works at my network providers office but still nothing at home. Please can anyone suggest anything else?
