Wi-Fi checker for Australian homes

Find your home's Wi-Fi dead spots

Use your phone to check each room and see where the connection gets worse. You don't need to draw a floorplan first.

First, stand next to your modem

We'll take five readings here so the scan knows what a strong connection looks like. Once that's done, walk to another room and wait for the reading to settle.

Take your phone for a walk

  1. 1

    Stay beside the modem. Keep the phone still while it takes five readings.

  2. 2

    Walk to a room and stop. Wait until the confidence changes to Medium or High.

  3. 3

    Save the bad spots. Tap Mark this spot. You can name it later.

The scan uses about 7 MB each minute. Your phone may keep the screen awake while it runs.

A browser can't read Wi-Fi signal strength. This tool compares the speed and response time in each room with the readings taken beside your modem.

Why Australian Homes Have Wi-Fi Dead Zones

Double Brick Attenuation

Standard Australian double brick and concrete block walls absorb RF frequencies heavily, reducing 5GHz speeds by up to 75% across just two walls.

Doorways & Hallways

Door openings create line-of-sight RF channels down central hallways. Placing your router with direct hallway visibility maximizes signal across bedrooms.

Mesh Node Halfway Rule

Never place a mesh booster in the dead zone itself. Place it halfway between your main router and the weak room so it can receive and re-broadcast a strong signal.
