The Telstra Wi-Fi Maximiser provides a free way to test the Wi-Fi capabilities within your house or office. It provides a cheap and effective heat map to understand where you can get best use of your network.
There is a short simple video on how to use it by Telstra on YouTube.
The great thing, it doesn’t matter if your Internet provider is Telstra or anyone else in the world, it is just testing the strength or your Wi-Fi signal from your router.
The steps are very easy. Start the app, create a rough mud map of your house floor plan.
Plot points on the map, while moving to those locations in the house.
