Macbook pro does not connect wifi

macbook prowifi

I have mac book pro late 2013 with os x 10.9.2. When i clicked on the wifi network i want to connect, it doesn't connect. It doesn't even give any response. There is only an animation in wifi: on option in upper right side with loading circle and becomes wifi: looking for networks . And it goes back to normal repeatedly

I tried to fix it by looking into settings, i even re-installed os x but it still doesn't connect. The network i want to connect is fine, there are 2 more devices connected to that network and they work just fine. How can i fix this problem?
