any help will be HIGHLY appreciated  There is not such a thing. Your connection speed to any of the servers on internet depends on what path your packets are sent. The slowest connection between (that your packets USE) will dictate the connection speed. You will have a speed to site A, most probably another speed to site B and so on. When you use a web based speed tester, you test your connection between your computer and theirs. This is not an accurate identification of your network speed, it is an accurate representation of your network speed in THAT PARTICULAR MOMENT to THAT PARTICULAR SERVER. Change the moment or the server and you most surely will have other values.

Even in your local area network the available bandwidth (hence "network speed") varies in time.Here is a software program I just found using google. I haven't used this before, but as viking says, you will never get the exact same results using the same program/web based connection speed tester.

You get allocated a bandwidth that can, and most certainly will vary depending on what server you are sending/receiving data to/from. Then there's the variables to take into account at that moment in time you are testing it... network traffic etc. etc.

If you haven't already, try Speedtest.net as this is a good site, in my experience.

Thanks alot dear check the SPEEDTEST.NET WEBSITE it is really useful one as i NEEDED
