no internet connection

I have a HP Pavilion dv7-2185eb Entertainment Notebook.  Since this weekend i have no internet connection.  I have (wireless) connection to my home network (can see network drives, home group,...), but I cannot acces internet.

When I hover in the task bar on the wireless icon it says internet access.  When I go to network center, it says I have internet access.  With all browsers (IE, Firefox) I cannot acces web pages.  I go to problem solving of network, but Windows says it cannot solve the problem.

Thanks for a solution.
