DSL Internet service only works over a limited physical distance and remains unavailable in many areas where the local telephone infrastructure does not support DSL technology.
Although DSL has been a mainstream type of Internet service for many years, the experience of individual customers can vary greatly depending on their location, their provider, the quality of telephone wiring in their residence and some other factors.
As with other forms of Internet service, the cost of DSL can vary dramatically from region to region. An area with few Internet connectivity options and few providers may be morecostly simply due to the lack of business competition.
DSL does not perform nearly as fast as fiber Internet connections. Even some high-speed wireless Internet options can offer competitive speeds.
Because DSL lines use the same copper wire as wired telephone service, all wired phones in the home or business must use special filters that plug in between the phone and the wall jack. If these filters aren’t used, the DSL connection may be adversely affected.
