Network times out in elementaryOS.

The network worked fine until yesterday. Now I cannot access any site because the network times out. Not even apt get works so I can't check for networking driver updates. I can connect to my wifi perfectly and it shows that I have a signal but it can't reach any website. I tried so many solutions on the internet and none of them worked. Please help because I am hopelessly lost and I am forced to use windows just because I can't use any internet-dependent app on elementary.
