Click the "+" button, add "8.8.8.8" to the list of DNS servers.

Click the "+" button, add "8.8.4.4" to the list of DNS servers.

(These are the Google public DNS servers.)

Click OK, click Apply.

Or, you can configure your router to automatically distribute that DNS server address to all connected clients; instructions vary depending on your model of router.
