Browser displays web page not available but Wi-Fi is connected?

Basically my laptops internet won't work, yet it's connected and is giving me Internet access, my Wi-Fi works on my ipad and my phone, as well as my brothers laptop. I'm stuck on what to do, I think it's a software issue because i tried pinging google if that does anything? Solution please?

I run a windows 8.1 Lenovo z500

Nope:/ this has been ongoing

Maybe to many users using the wi-fi try turning your mobile wi-fi off and check if it works!

Check the Wi-Fi signals and then proxy settings of your browsers.
