Manually testing your internet speed
This article will show you the best method for manually testing the speed of your internet connection, which is an alternative to our speed test tool. Manual testing can be useful for checking the speed of high capacity services such as nbn™ broadband or Cable broadband that require multiple downloads.
- You should run a speed test using a computer that is connected to your internet service with an Ethernet cable.
- For ADSL/ADLS2+, Naked DSL, nbn™ Fibre to the Node/Building (FTTN/FTTB) or nbn™ Satellite, your computer should be cable-connected to your modem.
- For Fibre to the Home (FTTH), nbn™ Fibre to the Premises (FTTP) and nbn™ Wireless, your computer should be cable-connected to the activated UNI-D port on your Connection Box.
- WiFi connections are typically slower than cable connections because the WiFi signal can get some interference.
- Disconnect any additional computers, gaming consoles, smartphones or tablets from your home network to rule out any data congestion.
- Go to http://ftp.iinet.net.au/ . Select one of the files such as "test100MB.dat" by clicking on the file name. As a rule of thumb, you should choose a file according to your service type as they have varying file sizes:
Fibre or any type of nbn™ broadband: Choose "test500MB.dat"
ADSL 2+: Choose "test100MB.dat"
ADSL1: Choose "test50MB.dat"
Dialup: Choose "1MB.dat"
- A popup box should open and ask if you'd like to Open or Save the file. In some browsers, this may be a popup bar at the bottom of the window. Select Save.
Note: Your web browser preferences may be configured to always save files to a particular folder, such as your Downloads folder. This happens when "Do this automatically for files like this from now on" has been ticked in the past.
- You should see your file downloading in a progress window. In some browsers, you may need to expand the Downloads window.
In Firefox, click the down arrow icon in the top right corner then select Show All Downloads.
In Internet Explorer, click View downloads in the download bar at the bottom of the window.
In Google Chrome, while the file is downloading, click Show all downloads in the bottom right-hand corner of the screen.
- When approximately half the file has downloaded, and take note of the data transfer rate, such as the examples below.
Microsoft Edge (Not currently suitable at March 2016)
As per the screenshot below, even the expanded download view of Edge does not currently show the data transfer rate for your downloads. Please test using a different browser until Microsoft makes an update to include this feature, or try our speed test tool.
As per the screenshot below, when viewing downloads in Safari 9 (the default browser for Mac OSX El Capitan) the data transfer rate is not shown. You may see the download transfer rate in older versions of Safari. Alternatively, please test using a different browser such as Google Chrome or try our speed test tool.
- For an approximate synchronization rate (line speed), take this data transfer rate and multiply it by 10.
Please note: for some high speed connection types, (e.g. nbn™ Fibre to the Premises or Cable) multiple downloads must be run simultaneously to access the full bandwidth of your connection.
