No connection

AC Question

I have an LG optimus dynamic 11 and it was working just fine until last week. Now I can use some of the apps on it but I am not able to connect with any online place, explorerer, or anything like that it tells me no connection. Yet when i open the network it says I am connected to my network and wi, signal is excellent. What do I need to do or look for to get this to work again.

Thank you
Gail
