How the speed test works:
The speed test will download a sample packet and then upload the packet and calculate the speed of your connection based on the results of the upload and download test.

There is a lot that you can do to help speed up your connection speed.  To read more about what you may be able to do, please click here for more information.

How the internet speed test works:

The internet speed tests require that you have adobe flash software installed on your computer.  If you can see the internet speed test's gauges above, then you have flash installed and can run the test.  When you click the "start speed tests" button,  a sample packet of useless information is downloaded to your computer.  This packet contains a file with worthless information (numbers, letters, etc..) so you don't have to worry about downloading anything harmful to your computer.  The test computes the time it takes to conduct the download speed test using the known file size of the sample packet and the time it took to download that sample packet.  The internet speed test then uploads the sample packet to the server and calculates the time it takes to conduct the upload test.  Using this information it determines the speed of your internet connection.

There are many factors which may affect your connection speed.  The connection speed tests only measure the time it takes to download and upload a sample file with a known file size.  The number of other users sharing the same connection in a household or business, other open browsers you may have running and programs you are running on your computer which are communicating with the internet will all affect the results of your speed tests. 

For the most accurate results we suggest the following:
  • Close other open browser windows.
  • Shut down any programs which may be running such as audio/video players and word editing programs.  If you double clicked on the program to start it, you may want to consider saving your work (if needed) for the duration of the internet speed test
  • Conduct a few internet speed tests in a row and average the tests together.
  • Conduct the speed tests at different times of the day and different days of the week. When you run the speed tests, you may find that your connection is slower when more people are home and using the internet.  Running the internet speed tests late at night may result in higher download and upload speeds because many users may be sleeping and are thus not using the internet.
    * For example:  If you and everyone on your street is using a certain cable internet provider, imagine that the data that you are downloading and uploading from the internet is water and the lines which the data run through are pipes.  Now imagine a pipe running down your road with connections to everyone's computers on your street.  If you are the only one using the internet on your street, your date (the water) can move quickly through the lines (the pipe).  As more people get online from their home, more data (water) is being forced through the same lines (pipe).  As more people access the internet and are passing data back and forth, the data will not be able to move as quickly and as freely as if you were the only one.  Now imagine that on a much larger scale and you have a basic understanding of why your connection speed test results may be lower when more people are using the computer than if you conducted the speed test late at night when less people may be online.

Speed up your internet connection:

Some ways to increase the speed of your internet connection may be out of your control such as the types of lines the internet service provider is is using to carry the data to and from your computer, the maximum download and upload speeds that your internet service provider allows, the number of users on the whole network, weather, and other factors.  Below you will find a list of things that you may be able to do to help increase your internet connection speeds.
  • Defrag your hard drive: If you think of the files on your computer like books in a library, then you may understand that if they are arranged correctly you may be able to find them quicker.  The defrag tool on your computer helps to arrange the files so that they are accessed more quickly.  On windows systems, the defrag tool can be found at Accessories / System Tools / Disk Defragmenter.
  • Run a virus scan of your computer.  An unusually slow internet connection is sometimes a sign that your computer has become infected.  Comodo makes a good free anti-virus and firewall and can be downloaded here.  If you would like to conduct an online scan of your computer, Trend Micro offers a free online virus scan which is easy.  Remember that you should always ensure that your antivirus software is updated with the latest signatures to help ensure that you are able to identify the latest viruses. 
  • Reset your home network:  You may find that resetting your home network router will drastically increase your internet speed.
  • Check your browser "cache" settings:  Caching files allows you to save files to your system such as images that may appear on a web page.  Every time that you are visiting a webpage, you are actually downloading a file (the webpage) from the server where the page is hosted.  Every image on the page is also downloaded to your computer.  Your browser (Chrome, Firefox, Opera, IE, etc...) takes this file that you download and presents it to you so you can see the page rather than the code used to build the webpage.  By caching files such as images, you will not have to waste time and resources downloading the same image over an over again.  This will help make pages load faster.  In your browser, the cache settings are usually located under the "tools" tab.
  • Contact your internet service provider:  They may be able to help diagnose problems with your connection over the phone and help you to increase your connection speed.
  • Reduce the number of programs using the internet connection:  If you read the example above which used water flowing through a pipe as an example for data flowing through the lines, then you will better understand that the more programs using the connection to the internet, the slower the data will pass.   Limit the number of programs that you have running which are accessing the internet.  If you are using a firewall such as the free firewall from Comodo, you will be able to open the firewall control panel and see which programs are accessing the internet. 
  • Upgrade your router:  Routers have components that will eventually degrade over time due to heat.  Ask your internet service provider about the possibility of upgrading the hardware that they provided to you.
