I have a Lenovo G470 laptop and my OS is Windows 7 Ultimate. My problem is that my laptop shows that it is connected to the home network (via Wi-Fi) and it says All Internet Access, and I get full signals but when I try to open my browser and try to open "google.com" or "facebook.com" it says that webpage is not available. I've tried to connect my laptop in my friends house too, and the same thing happens. Can someone help me?
Please help.
I didn't find the right solution from the Internet.
