No net connection

I recently brought a router TP-LINK TL-WR740N 150Mbps.

I have cable net connection at my place. I have installed the router and i get the wifi signals but still their is no net on my phone as well as on my PC. When i connect my cable directly to my pc i get the internet connection. But i don't get it when i connect it to the router.
