internet speed test mbps

How can I make a internet speed test Mbps and use a LCD Display?

I wold like to use speedtest.net and google speediest.

speedtest.net, speediest and most of the other online speed tests require a browser that can render Flash or HTML5. An exception is http://speedtest2.aa.net.uk that is text based but still requires javascript.

The short answer is, you are unlikely to find a ready made, online speed test that you can use with an Arduino.

What you could do is create your own speed test by placing a large file (say 40MB) on a server (cloud storage) and then write the Arduino code to download the file, time how long it takes and convert to bits per second. However, at 16Mhz the Arduino CPU will lack the bandwidth to saturate any half decent broad band connection - You end up measuring the speed of the Arduino, rather than the speed of the network.
