4) The image will start to download, showing a progress window (see below);



5) Note down the fastest and slowest Transfer rates. Repeat the download as many times as you need to, simply overwriting the image file each time;

6) Multiply the Transfer rates in kB/sec shown in the window above by 8 to find the Transfer rates in kbps at the fastest and slowest rate;

7) The two calculated values (in kbps) are your upper and lower internet data transfer speeds.
