networkQuality allows for measuring the different aspects of Network Quality, including:

  • Maximal capacity (often described as speed)
  • The responsiveness of the connection. Responsiveness measures the quality of your network by the number of roundtrips completed per minute (RPM) under working conditions. See
  • Other aspects of the connection that affect the quality of experience.

NOTE: This tool will connect to the Internet to perform its tests. This will use data on your Internet service plan.
