How to Set Up an Internet Connection
If you have a properly configured broadband modem and router (for example, one set up by the installer when you order cable or DSL service), you might not have to do anything to set up an Internet connection. You can just connect your computer to the modem with an Ethernet cable and the Internet automatically becomes available to you.
You can open a browser and view a few web pages to confirm that your service is working.
Or, for a wireless connection, you can just connect your computer wirelessly to the router (or modem with router capabilities). To do that, follow these steps in Windows 8.1:
1In the notification area (the icons near the clock in the lower right corner of the screen), click the wireless networking icon, as shown.
The Networks pane appears.
2If one of the wireless networks says Connected under it, you are already connected to the wireless network. If not, click the wireless network you want to connect to.
Networks with a shield icon on them are unsecure networks. Anyone may connect to them. Networks without the shield are secure and require a password.
3If the network you connect to requires a password, and this is the first time you have connected to it, a prompt appears.
Enter the network password and press Enter.
