A broadband Internet connection is a high-speed Internet connection—in contrast to a dial-up connection, which is slower and not powerful enough to support a wireless network. Digital Subscriber Line (DSL) and cable are two of the most common broadband connections. You can get a broadband connection by contacting an Internet service provider (ISP). Typically, ISPs that provide DSL are telephone companies and ISPs that provide cable are cable TV companies. ISPs often offer broadband modems and might even install it for you. Some ISPs also offer combination modem/wireless routers. You can also find these at computer or electronics stores.
