I have seen several apps on the market that are allowing users to determine their current network connection speeds. How is this possible, and what might I use to be able to use this functionality? I am querying network types but I am not sure how to determine the current speed of the connections.

    Without testing the connection, there's no way to know. Being connected to wifi for example doesn't mean that the internet connection is anything but a slow connection. And, testing the connection could use an expensive data plan, which would not be recommended unless the user authorized it. – WiredPrairie Mar 13 '14 at 10:57

Besides the NetworkInformation class that gives you basic information about the connectivity (network available or not, wifi enabled or not) there is no API with the current SDK for determining network speed.

I guess the apps doing this simply create a web request to download some sample files hosted on their website and measure the time it takes, etc.

  • In doing some more research, I see some solutions are using javascipt within a webbrowser to do what you say with an image. How might I set something like this up on my device? I do not have experience with javascript except for basic navigation in a webbrowser control. – Matthew Mar 20 '14 at 01:05
  • Yes, you can interact with the webpage via ScriptNotify (Javascript to C#) and InvokeScript (C# to Javascript). – Olivier Payen Mar 20 '14 at 08:17
  • After much research/trial/ and error I have what I believe may give me the solution I need, although the value returned is `NaN`. Thought you might be able to take a look and see if anything is wrong http://stackoverflow.com/questions/22777362/calculating-speed-using-javascript-returns-nan – Matthew Apr 04 '14 at 20:28
