Ensure that your computer is capable of picking up wireless broadband signal. Some computers come preinstalled with internal wireless cards, whereas others require the purchase of an external wireless card. Read your computer specifications to determine which type you have. If your computer requires an external wirless card, you will have to purchase one before proceeding to the next steps.
Locate and go to a Wi-Fi hot spot to get free broadband access. Numerous businesses offer free Wi-Fi to attract consumers, such as McDonald's, Starbucks and many hotel chains. Conduct a search for Wi-fi hot spots in your area, and then go to the one nearest you and order a coffee or soda so that you can use the business's free wireless signal. (Oftentimes businesses require you to purchase something if you plan on sitting in their area for an extended amount of time).
Purchase a wireless antenna so that you can pick up a longer range of wireless signals, and then connect to unsecured wireless networks like other home networks and free business Wi-Fi.
