The Digital Subscriber Line (DSL) uses existing phone lines
to provide high-speed Internet access. DSL provides this access without dialing
up phone lines just like dial-up Internet connections.
Compared to cable internet service performance, DSL speeds
have historically been a little behind. However, as technology improves, DSL
Internet connection speeds are increasing and service providers upgrade their
network infrastructure.
The speed of DSL you can use varies depending on the
provider you choose and the package you offer. Your equipment can also affect
speed. If you use a wireless router and your computer is away from the router,
you can expect a slower speed. This happens if your router or PC is old enough.

How fast is DSL?
The average DSL internet speed is almost as fast as a cable
internet connection. However, cable connections are often shared with other
customers around you, which can slow down. The DSL service is not shared with
others, so your neighbors' activity does not affect your speed.
DSL speeds vary widely by package options. If you want to
watch too much streaming content, you want your provider to have a fast
package. If you are not online 24/7, a more affordable, but slower package
might be right for you. Most providers choose DSL services with a different
bandwidth.
For example, AT&T offers a range of services that can
deliver speeds of up to 6 Mbps and another range that can deliver up to 100
Mbps (VDSL or very high-bit-rate DSL). Slow, inexpensive planning works well
for social media, browsing and email. Gamers and TV binge-fast planning fit
well. For comparable cable speeds, their Fiber Plan delivers up to 1000 Mbps.
DSL download and upload speeds
Depending on the network you use, your DSL speed may vary.
DSL providers often advertise their service speeds using a
combination of two bandwidth numbers: one download speed and one upload speed.
When you select a internet service provider, check both download and upload speeds.
Residential DSL services generally provide faster speeds for
downloads than uploads because most users devote more time to download
activities. This arrangement is called asymmetric DSL (ADSL) service. In ADSL,
the download speed is much higher than the upload speed. With Symmetric DSL
(SDSL), the two numbers are the same.
DSL speed difference between homes
The rated maximum bandwidth of a DSL connection is often
unreachable and the actual speed varies between households. Factors affecting
DSL speed include:
Resident Phone Line Quality in Your Residence: Environments
with improved copper wiring can achieve some faster DSL speeds. Fiber-optic
lines are much faster.
Distance between hub and home: The length of the phone line between the
resident and the phone company hub affects the speed. DSL technology is
distance-sensitive because its performance decreases when the hub passes.
Mal Service Errors: DSL speeds may fall suddenly if the
service provider is experiencing technical difficulties in its network and is
usually stable. The speed usually returns to normal after a few minutes.
Before re-opening their residences, customers can do very
little about changing certain items. However, other factors can be changed to
improve connection speed.
