I cannot log into internet via wifi

If your phone shows that you have a WiFi connection, then you should have access.

So what are you trying to do, exactly, and what is happening, exactly, when you try?
 
I understand that. However 'how' are you trying to access the internet? Through the browser app? Through a different app? What app exactly? And when you try to access the internet through whatever app you are using, what is the exact message you get?
