your Internet connection working at the speed
of light or is it slower than a rainy day? Sometimes
it's not just your imagination. There are many
things things that can cause you internet connection
to slow right down. Our Internet Speed Test
can tell you exactly how fast data is being
recieved by your computer, whether you're using
a state-of-the-art wireless connection, integrated
services digital network (ISDN) connection,
satellite or just a plain old dial-up modem.
do I get different speed results each time I
run the test?
like a major high way or intersection, the rate
at which information travels across the internet
is dependent upon the amount of traffic. Information
travelling to your computer often has to wait
while data on its way to other computers passes
through intersections, or 'routers'. If there
are very many users online, this can slow your
connection speed considerably.
is worth remembering that in the same way that
it takes longer to get home from work during
rush hour, you are more likely to run into Internet
traffic jams during peak use hours, than during
those times when fewer people are online, such
as after 11 p.m. and before 7 a.m. If you really

thought my Internet connection was supposed
to be faster. Why does the Speed Test come up
with a lower figure?
Internet connection ever performs at 100%. There
is always some loss, and the faster your connection
is, the greater that loss is going to be.
this page can only measure the time it takes
the applications data--the actual data file--to
reach your browser. Wrapped around that data
is some overhead that can range from 2 percent
to 25 percent of the total data sent. There's
no way for the program built into this Web page
to control or discover exactly how much overhead
was used to send the page's internal data file,
but generally the percentage is small, and this
page adjusts its figures up by 2 percent to
compensate. Nevertheless, the actual overhead
may be higher than expected, resulting in a
depressed value for the Kbps figure.
remember that your connection to your ISP is
just one part of the system that gets data to
your computer. Between your computer and the
server that sent this Web page there are probably
a dozen or more routers, communications links,
and other network components this page had to
travel through. Each of these components have
a set capacity and speed at which they can operate,
and most of them handle network traffic for
thousands, even millions of computers every
day. The inevitable result is that all Internet
traffic encounters some sort of delay as it
transits across The Net, and that reduces the
amount of data that gets funneled into your
connection in the first place.
getting a big slowdown. Could my Internet Service
Provider (ISP) be the cause of my problem?
The delay could be at your ISP, or it could
be elsewhere. (See the explanation above) But
if you're consistently getting Internet Speed
Test results that are substantially below expectations,
the root problem is likely to be your ISP's
fault or a very poor quality phone line.
your dial-up modem, DSL, ISDN or other Internet
connection may be a dedicated line, all of an
ISP's connections get combined into one or more
shared connections. In most cases, these shared
connections have less capacity than the combined
total of all the customer connections they serve.
Done judiciously, this works better than you
probably think. Since most Internet users spend
more time reading their email and Web pages
than they do downloading them, they're only
using a fraction of their connection's actual
capacity. Overbooking allows an ISP to combine
several customer connections into a single link
that's smaller (and less expensive) than the
combined total of all the connections they serve,
without reducing the amount of data sent to
a customer when they are downloading data.
problem is that some ISPs take the overbooking
concept too far. They funnel so many connections
into a small combined connection that normal
customer demand overwhelms the capacity of the
combined connection. This is a particular problem
during peak use hours, when line speeds can
slow to a crawl. Unfortunately, there is no
remedy for this problem. As competition in the
high-bandwidth Internet connection business
heats up, you'll have more options and your
ISP will have more incentive to maintain more
reasonable overbooking ratios. Until that time,
however, your only options are to complain to
your ISP or switch to another Internet provider
with a better track record.
have a 56K modem. Why isn't my download speed
even close to 56K?
could be several reasons--and most of them aren't
your ISP's fault.
of all, static electricity caused by radio signals,
power lines, and other sources interfere with
most 56K modem signals, forcing them to fall
back to 42-50Kbps.
modems also require a clean, straight through
telephone connection to the telephone company's
central office switching center. Phone company
line amplifiers that boost a telephone signal
over a long distance, PBX switchboard systems,
and other phone equipment alter the phone signal
and force 56K modems to fall back to speeds
of 33.6Kbps and lower.
no 56K modem ever connects at 56K. Most 56K
modem users seem to connect at speeds of 44-48Kbps.
In country areas it is rare to get a conection
of 33.6Kbps or greater.
