AT-Tester is a simple, user friendly software application built on FOSS (Free and Open Source Software) which can test the performance of any broadband link irrespective of technology or the type of package. It is a joint effort of LIRNEasia and a team from IIT Madras, and developed based on AshokaTissa (AT) methodology of broadband testing.

The tests can be conducted by any user, with least effort and within few minutes. No more than basic computer literacy is required. All you need is a PC running Windows XP connected to Internet. (Other operating systems will be supported in near future).

AT-Tester is different from popular broadband performance testing tools (speedtest.net, for example) because:

  1. It is more accurate: AT-Tester measures the throughput rates while actually downloading/uploading files. It does not calculate them using empirical formulae and ping data.

  2. It is more comprehensive: Unlike most other tools, AT-Tester does not confine testing to an end server. It tests the throughput to three servers, namely (a) the local ISP; (b) another server within the same country and (c) a server in US. This helps pinpointing the bandwidth bottlenecks.

  3. It tests more parameters namely,

  • Download speed (kbps/Mbps)
  • Upload Speed (kbps/Mbps)
  • RTT (milli seconds)
  • Jitter (milli seconds)
  • Packet-Loss (%)
  • Availability (%)

The software is developed in such a manner that minimal configuration is required by the user.

This is all what you have to do.(It is just six simple steps)

1. Download Software

Please use the link: Download.

There is an alternative version for Download which will not prompt a message box if you test using scheduler option.

2. Install

What you download is a zipped an archive file which has to be extracted and then run. It contains a self-extractable EXE file named 'Setup.exe' that installs by default in C:\Program Files\ATtester directory. User can change the installation directory if required. In the desktop the software will be placed as a shortcut with name 'AT-Tester'. Please read 'Read Me' file if you want more information.

3. Register

Once installed and run, click on the 'Register' button in the main window and select your ISP details for registering the AT-Tester client. If you don’t find the exact Download Bandwidth select the closest. If there is a significant gap please write to us first () so we can include it and let you know when it is ready. Same if you do not find your ISP in the dropdown list.

4. Run

After receiving confirmation of successful registration run the tests at any point of time manually by clicking on the 'Run Test' button. You can also schedule the tests to run at specified times automatically using 'Schedule' button. However, we do not recommend this on your first attempt.

5. View results

View the test results using the 'Result' button.

6. Upload results

Upload the test results to the our server by clicking on the 'Send Result' button. This will enable us gathering information from many users like you so we have a more detailed picture.

Thank you for your interest.
