DSL service in Wisconsin is available in most areas that are within a specified distance from a provider's equipment. DSL is much faster than dial-up, with download speeds ranging from 256K per second to 24MB per second depending on the type of technology and distance from the provider's central office.

DSL, short for Digital Subscriber Loop or Line, is a high-speed Internet connection over telephone lines. It uses a higher frequency than voice transmission so you can use your phone and access the Internet at the same time.

DSL is set up by installing a DSL modem or router that connects to a phone jack. To prevent feedback and noise, a filter is placed on the phone line to block out the high frequencies used for data transmission.

Wisconsin DSL providers are plentiful. In most areas, Wisconsin consumers have a choice of telephone service providers and most of them offer DSL. There are also independent ISPs that offer DSL. Some things to do to help choose DSL in Wisconsin include:

1. Compare the costs of Wisconsin DSL services.

2. Check out the service level agreement and support packages.

3. Review other services that are bundled with the DSL package.

Find out if your telephone service provider offers DSL in Wisconsin

Wisconsin stands out from many states in that consumers in most municipalities have a choice of telephone providers. Many providers also offer DSL. Check with your telecom to find out if DSL is available and what packages are offered.

I recommend: Some of the larger local telephone companies that provide DSL are AT&T (formerly Wisconsin Bell) and Verizon. Many smaller companies like CenturyTel and TDS Telecom provide expanded business services such as computer security software, business bundles and web hosting.

Check out independent providers of DSL services in Wisconsin

A Wisconsin DSL provider that is independent from your local telecom is a good choice if you are unhappy with the telecom's customer service or if you're looking for additional technical products.

I recommend: Covad is an independent telecom that offers telephone lines as well as DSL and other Internet services. Eskimo North is a "Linux friendly" DSL provider that includes Unix shell access and other features. Green Bay Net provides web hosting, web design and consulting services.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Keep in mind that DSL providers that don't own the phone lines have limited control over system outages and service levels. Independent providers of DSL Internet service in Wisconsin may provide more competitive pricing and better business packages than the major telecoms. However, it can take longer to resolve service issues.
• •  Find out whether the provider offers a free router with its service. DSL can be routed across your network, but speed will be reduced as more people use the connection. Many DSL routers include firewall and routing services. Consider upgrading your router if it doesn't meet your needs.
