Dell Inspiron Mini 1012- Connected to WIFI but will not connect to Internet.

Hello, 

I have a Dell Inspiron Mini 1012. It was working perfectly fine until a week ago. When I would tey to open the browser ot would bring up a server error. It shows that I am connected to my wifi but is says there is no internet access. I do jot have any of the original stuff that came with the laptop and I have no other internet access except for my phone. I have tried to connect with an ethernet cable but it still says it will not connect. It has windows 7 starter, and it shows Google Chrome on the desktop. What do I do?
