When you connect to wireless network you’re usually given an IP address.

We used settings that work for our configuration, but you might have to enter different data. In addition, you’ll have to enter the DNS server manually. In our example we used Google’s Public DNS, but you can also use 192.168.1.1 as your Preferred DNS server.
5. After you’re done, click the OK button.
