My macbook pro is connected to the network but I cannot browser any website

I am having a hard time figuring out what's wrong with my laptop. I am using my laptop and my computer, both connected to the same network but something went wrong. I cannot browse any website using my laptop but when I tried it on my computer, it works just fine. It says in my laptop that it is connected but then I still can't browse anything. Pls. pls I need help. Thanks!
