Most people, particularly in urban and suburban areas, enjoy several options for how to connect to the internet. The connection method you choose affects how a home network must be set up to support internet connection sharing.
Digital Subscriber Line
DSL is one of the most prevalent forms of internet connection. DSL provides high-speed networking over ordinary phone lines using digital modems. DSL connection sharing can be easily achieved with either wired or wireless broadband routers.
In some countries, DSL service is also known as ADSL, ADSL2 or ADSL2+.
Cable Modem Internet
Like DSL, a cable modem is a form of broadband internet connection. Cable internet uses neighborhood cable television conduits rather than telephone lines, but the same broadband routers that share DSL internet connections also work with cable.
Cable internet is perennially more popular than DSL in the United States, but in many other countries, the reverse is true.
