Wifi is connected but internet can't be accessed.

[Anantha_Krishna]

I have a HP 110-mini laptop dual booting Ubuntu 13.10 and Windows 7. I am trying to build LFS. But recently, my internet access just went off. It says I am connected to the wifi and I can access the internet with other devices, I can also access internet on the same laptop when I am booted into windows 7. Only when am on UBuntu every browser says server can't be found.
Can you please help me?
