How to Test a Comcast Broadband Speed

Comcast is a well-known cable television and Internet provider that offers service in many states across the United States. If a Comcast broadband Internet connection is running slower than it should be, one should first check and test the connection speed of the package they are signed up to have.


  1. Perform an Internet search using the keywords "free Internet connection test." This search should provide you with a variety of sites that offer free Internet connection speed tests.

  2. Browse through the search results to see what is available. You should choose a website that offers a quick and easy connection test free of charge.

  3. Choose the website that you would like to use to perform an Internet speed connection test and click on the link.

  4. Choose a server that is closest to the area where you are located when prompted to choose a server. The closer the server is to the location of the connection, the more accurate the test results will be.

  5. Click on "Start Connection Test" and allow the test to run through its course entirely. Do not click on anything else during this time. The test typically takes between 30 seconds and 2 minutes to complete.

  6. Record the results of the connection speed that the test determines is the speed of the Internet connection currently and compare these numbers to the advertised connection speeds that you are paying for.

  7. Contact Comcast customer service if the speeds you are receiving are lower than the advertised speeds that you are currently paying for. Comcast can send out a service technician to determine the source of the problem for you.
