my connection is 768 kbps but when i made a speed test the result was 140kbps..... why???

Answer 1

Speeds are tricky,,,They are sold at "Advertised Speed".

It's a situation a Lot like publishing Fuel Mileage figures for Cars.
The fine print always says,,"Your Mileage May Vary"

Generally,,Your connection speed should be about 80% of the advertised speed.
Roughly 600kb ~650kb in your case.

And though it's not "RIGHT" to see it vary widely and drop down very Low sometimes....
That's how Most All connections go,,,they DO act goofy.

Several things affect Speed.

First,,whenever You test,,,Do 2~3~4 Tests and take an average.
I'd say do At least 3 tests consecutively.

Different Test Sites will yield Different Test Results,,,and the differences can be quite a lot in some cases.
But you Still should expect that "80%" figure as a minimum.

On common problem is Line Noise on the Telephone Wires.
(I'm assuming you have DSL and not Cable?)

Establish an Avg Test Speed via several tests,,and if it continues to be LOW....
Unplug EVERYTHING in your house that's plugged into the Phone System.(Except your Computer,of course)

Then Re-Test 2~3 times and see if that makes any improvement.

Some Telephones ,,Answering machines,etc cause "noise" in the frequency range used by DSL.
If You DO see an improvement,,,Reconnect the items 1 at a time,and Test Speed to see if You can find the possible "offender"
....................................
Sometimes you can ReStart your DSL Modem and connect to a different server.
Try That,,,switch Modem OFF then back on,,,and see if you get any improvement in speed.

............................
You can try "Repair Connection">>>
*Double click the Modem Icon in lower r/h task bar
*Click on Support tab,,then on REPAIR connection

TECHNICALLY---that should make No Difference,,Windows should manage that itself.
REAL-WORLD---Sometimes it makes a difference.

.......................
Windows comes with Communication Settings which are Default Values for DIAL-UP Modems.(36Kb Modems)
They DO Work with Broadband/Hi-Speed---but are rather Restricted.
The Reason is>>>So a New,Fresh Installation of Windows will Consistently/Reliably CONNECT,,"under any conditions".
Plug in any sort of Modem,,,and it'll at least WORK.

As the Com Settings are tweaked to allow Higher rates of Data Flow,,,Sensitivity increases and a variety of probs can occur.
So the Default Settings are the "FoolProof" Settings.

Here is a simple "Auto-Fix" which changes certain settings.
It's Free,quick,,cannot hurt,,is Un-do-able,,and often shows some improvement.
**It Only adjusts a few Windows SETTINGS to optimize for Broadband/Hi-Speed.
It Does NOT cure any actual Problems

Follow the instructions,,it's very easy.
You may want to Bookmark the page,,,
or write a note somewhere so you can return to the page if ever necessary

Here's a link to their Speed Test,,,,a link is also on their Auto-Fix page

http://pcpitstop.com/internet/default.asp

PCPitstop Test DOES require downloading a few small programs to do the functions,,,,
But it's a VERY CLEAN site,,,No Spam,No Crapware/Spyware/Pop-ups,,etc.

They also have a "Full Test" that tells alot about your PC,,ya may wanna try it just for grins

.............................................
If You Connection Speed Remains Low,,,,best place to start is to Contact your Service Provider

Hope any of that helps!

I'm assuming from those speeds, you have DSL from your phone company. There are two important things to know about DSL speeds. 1: The farther you are from the phone company's local hookup, the less bandwidth you get. 2: You're probably buying Asymetric DSL, which just means you get different speeds up than you do down. You can probably download from the internet much faster than you can upload, which is fine for most people. If you're running a webserver, do a lot of file sharing, or offer other services for outside users, your upload speed matters. Were you testing download speed or upload speed?

If you're encrypting your traffic (often done when you work from home, or do online banking) you'll slow things down.
If your computer is having problems, you can slow things down.

If that speed testing program wasn't all that accurate, you can get a low number. You'll get different speeds doing different things.

If there's something the matter with your telephone line, you can get terrible static on the line. If this is the problem, common sense can point it out. If you only have speed problems after a storm pulls your phone line partly loose, or when someone's using the phone, you can narrow down the problem quickly.

My advice: test again with a different program, jot down a few notes on what kinds of problems you've been having, then call your DSL company. The techs may be able to help you figure it out, and if not, talk to customer service. Tell them that the speeds aren't what they advertised, and they need to either fix it, or give you a credit.

Answer 3

Hi,

768 kbps is your service providers advertised speed, but your actual speed depends on the time you are doing the test, the area you live in and the test server you are using, my best bet is that the area you live in is densly populated and many people use the same provider and similar service from them, so the total bandwith is being distributed among your neighbors and others who access the same Point of Presence (PoP) office from your proivder, Also how far you live from this PoP office also makes a different if this is a DSL service

Check the link below that explains Line Sharing

Answer 4

Contact the service provide or else 768kbps could be at the non-peak like check the speed between 10:30 pm and 6:00 am in the morning. If it shows the samething in this timing you got to contact the service provider.

Answer 5

It depends on the nature of your test. Is it possible that some of the data came from a local cache or was compressed by a piece of software/hardware?

Answer 6

possibly, the line distance from the transmission/receiving station is longer than 14,000 ft from your house. The longer the distance, the more line degradation....thus your speed is reduced.
Check with your provider and ask for technical help.

Answer 7

Delete all files in catche then delete all trace of being on the web and o the test again

Answer 8

with the xbox 360 u only need 2mbps which is 2048kbps so yes it will play fine, u could end up with a bit of lag now and again depending on what game your playing and who your playing with

Answer 9

download a program called cablenut and try that you'll need to configure it to your system specs
