To enable WiFi inside of your home you will need to set up a wireless router. Routers can be purchased at retail stores, such as Wal-Mart, Target, or Best Buy. Your computer will also need to have a wireless adapter in order to connect to the router. Most laptops come installed with this feature.
Each router is different, so be sure to follow the installation instructions that came with the router. However, these are generally the steps you will need to follow in order to set up your wireless router.
