They provide a customizable gateway, or home page, that usually offers fast access to news feeds, email, and new multimedia content that's keyed to your IP address. When people hear of a free offer, they love it, as they love any freebie. DSL internet access is so much faster than dial up that just for convenience sake DSL is a much better option. Today, many companies, like AT&T, market their own brand of DSL service. Cheap DSL is just as good as anything more expensive, at the end of the day, it's only wires after all. That might be all it takes to get back up to speed.

While you will find DSL quite popular and preferred outside the United States, within the United States cable Internet is still number one. You will first need to find out if your local telephone company offers any type of cheap DSL service. We'll help you figure that out. It's a scam. A router enables more than one computer to share a DSL connection, and for those computers to communicate back and forth with each other. This is not to say that a wireless DSL router can't develop other, temporary problems.
There are three factors to keep in mind when contemplating DSL availability: Distance, distance, distance. Well, that's one word three times, but it's still the most important factor in whether you get DSL service and what level of quality you can expect.
This distance means that DSL availability has yet to reach every corner of the country, despite popular demand. We'll look at why this is and what secondary factors matter, below.
Copper Wires
Regular DSL, the sort you'd order for home service from a provider like Yahoo, is carried from the provider to your house by the pair of copper wires that are already carrying your phone service.
As a digital signal travels farther and farther from its source, it degrades. Think of it like a radio station you're listening to when suddenly you drive through mountains. The signal dissolves into a bunch of unintelligible static. The same thing happens to a digital signal.
So generally, you have to live within 18,000 feet of the service provider to qualify for DSL availability. No one expects you to get a ruler and measure the distance to the nearest service provider. There are several websites that will let you input your address, then tell you whether or not you qualify.
Even if you're within 18,000 feet and do qualify for DSL availability, the closer you are to the provider's office, the faster your DSL will be. Service at 9,000 feet distance is nearly eight times as fast as service over 18,000 feet.
Load Coils
A secondary factor affecting DSL availability is a tiny device installed by some phone companies called a 'load coil.'
The copper wires carrying your phone service have a broad bandwidth - that is, they can handle a wide range of frequencies. The human voice is clearest from 300 to 3,400 Hz, so that's the portion of wire reserved for telephone calls.
When the telecomms decided to add DSL availability to the same copper wires, they opted to use frequencies in the 4,000 Hz and up range. This shouldn't have been a problem except that some companies had added load coils to the wire lines.
Load coils enhance the lower frequencies. This equals clearer voice transmission, but can interfere with DSL availability. Ask your telephone service provider if this is the case on your lines. You might want to consider going with a cable provider instead.
So don't take it personally if you find out you don't qualify for DSL availability. The problem is with the telecomm, not you!
