For many NBN users in Australia, experiencing a strong internet connection in one room while struggling with slow speeds in another, especially on upper floors, is a common issue. The internet speed provided by your service provider doesn't always guarantee a reliable Wi-Fi signal throughout your home. This is particularly true in houses with thick walls or concrete floors. Mesh Wi-Fi systems offer a solution by using multiple interconnected units to expand signal coverage, rather than relying on a single router.
What is Mesh Wi-Fi and How Does It Work?
A mesh system typically includes one main router and several additional units known as nodes or satellites. These nodes communicate with each other wirelessly, simplifying the installation process. It's important to note that while mesh Wi-Fi cannot boost your NBN speed, it can help ensure that more of that speed reaches your devices.
The primary advantage of a mesh system is that all nodes share the same network name and password. This means that as you move around your home, your devices will automatically connect to the nearest node, maintaining a stable connection throughout. Since mesh systems are connected wirelessly, there's no need for additional Ethernet cabling. However, if you have Ethernet ports available, connecting nodes directly can enhance performance.
Mesh Wi-Fi systems are particularly beneficial when your internet speed is good near the router, but significantly drops in other areas of the house. If you still have slow or weak spots, adding more nodes can help extend coverage, even to multiple floors, garages, or through barriers like double brick walls and concrete floors.
Limitations of Mesh Wi-Fi
While mesh Wi-Fi can address many connectivity issues, it is not a cure-all. It won't increase your NBN speed, fix existing connection problems, or alleviate congestion from your service provider. Additionally, mesh systems can struggle if nodes are placed too far apart or are obstructed by physical barriers.
A simple test can help determine if a mesh system could improve your connection. Conduct a speed test using speedtest.net next to your router, then repeat the test in the problematic area with the same device. If there’s a significant difference in results, poor Wi-Fi coverage is likely the issue. If both locations yield poor results, it may indicate problems with your internet service, router, or device.
Compatibility with NBN
Mesh Wi-Fi works with various main NBN connection types, but the setup process can vary based on your specific equipment. For Fibre to the Premises (FTTP), Hybrid Fibre Coaxial (HFC), Fibre to the Curb (FTTC), and Fixed Wireless connections, the main mesh unit typically connects to the NBN connection box via Ethernet. This unit can often replace the router provided by your service provider. You may need to enter specific provider settings first, usually through an easy-to-use app or setup wizard.
For Fibre to the Node (FTTN) and Fibre to the Building (FTTB) connections, a compatible VDSL2 modem is necessary to manage the connection over existing copper lines. Mesh routers cannot replace this modem but can connect to it to handle Wi-Fi throughout your home. If you're unsure, your service provider can confirm the best setup for your connection.
Do You Really Need Mesh Wi-Fi?
Implementing a mesh system makes the most sense when a single router cannot reliably cover your entire home. This situation often arises in multi-story houses, homes with double brick walls, converted garages, or granny flats. If you live in a compact unit or apartment and have reliable Wi-Fi in every room, you might not need a mesh setup.
Relocating your router, upgrading to a newer model, or connecting key devices via Ethernet could resolve your issues at a much lower cost. Basic Wi-Fi extenders can also be a more economical choice if you're simply looking to fix a small weak spot. While mesh systems are generally pricier, they tend to be easier to manage if you have multiple problem areas.
How Many Nodes Do You Need?
The ideal number of nodes depends more on your home’s layout and materials than on the square footage alone. A two-node system is a reasonable starting point for small townhouses or single-story homes, while larger or multi-story properties may require three or more nodes.
Having too many nodes does not automatically mean better coverage. Overlapping coverage can occur if nodes are placed too close together, while too few nodes can lead to connectivity issues, as each node needs a reliable link to the main router or other units. Nodes situated deep within dead zones may not receive sufficient signal to function properly.
Placing the main router or mesh node in an open area is usually best, though the exact location will depend on where your internet connection enters your home. Ideally, each additional node should be positioned a little over halfway towards any problematic areas. Higher and more open placements typically yield better results, so avoid positioning nodes on the floor or in cluttered spaces, and steer clear of placing them directly next to large appliances or behind thick internal walls.
Conclusion
Considering a mesh Wi-Fi system can be worthwhile when a single router fails to provide adequate coverage in certain areas of your home. While it won’t improve your NBN connection itself, it can distribute that connection more consistently throughout your space, especially in larger or multi-story homes. For minor coverage issues, repositioning your router or using an extender may be a more cost-effective solution.
