If you’re living in a granny flat, the best router option depends on whether the internet service is installed directly in your unit or shared from the main house.Normally NBN fiber box installed at the main house
🔹 1. Fibre/NBN box is installed directly in the granny flat:
You can use a regular standalone router AX1500 to AX3000 range that suits the size of the flat.
Recommended models: TP-Link AX1800 2 , ASUS RT-AX52，ASUS RT-57
Tip: Wi-Fi 6 models are better for speed and reliability in small spaces.
🔹 2. Internet is shared from the main house:
You will likely need a mesh system or Wi-Fi extender to extend the signal to your granny flat.
Best solution: Use a 2- or 3-node mesh Wi-Fi system (like ASUS RT-57 AX3000 (2 or 3-Pack)) — one node in the main house, another in the granny flat.
Alternative: Use a wired Ethernet cable from the main house to connect a second router or access point in the granny flat.
Tip: If the distance is far or there are thick walls, wireless signal may weaken. A wired backhaul (Ethernet cable) gives the most stable connection.
