If your internet feels fast in one part of the house and unreliable somewhere else, the problem is often local Wi-Fi coverage rather than the NBN connection itself. The most effective fix depends on where the bottleneck is, so start by separating an internet-speed problem from a wireless-network problem.

1. Test whether the problem is Wi-Fi or the internet service

Run a speed test close to the router, then repeat it in the room where the problem occurs. If practical, also test a computer using Ethernet. A healthy wired or close-range result combined with a poor distant Wi-Fi result usually points to the local network.

Our guide to NBN vs Wi-Fi explains this distinction in more detail.

2. Put the router in a better location

Wi-Fi works best when the router or access point is in a reasonably central, open position. Hiding it inside a cabinet, placing it on the floor or locating it at one extreme end of a large property can make coverage harder.

Avoid placing wireless equipment directly beside large metal objects, dense masonry, microwave ovens or other sources of interference where possible.

3. Do not assume one router can cover every property

A single router may be perfectly adequate for a smaller open-plan home but struggle in a long house, multi-storey property, extension, detached office or building with dense walls.

In larger properties, strategically placed wireless access points or a well-designed mesh system can provide more consistent coverage than asking one router to reach every corner.

4. Use wired connections for fixed high-demand devices

Where practical, Ethernet is useful for desktop computers, televisions, game consoles, workstations and other fixed devices. A wired connection can reduce wireless congestion while providing a stable path for devices that do not need to move.

This does not mean every device should be wired. Phones, tablets and laptops still benefit from good Wi-Fi. The goal is to use each connection type where it makes sense.

5. Consider how many people use the network at the same time

Good Wi-Fi cannot create internet capacity that is not there. If several people are streaming, gaming, video calling and downloading at once, the NBN plan itself may also need more headroom.

Use our NBN speed guide to decide whether the service tier is part of the problem.

6. Keep networking equipment supported and up to date

Routers and access points rely on firmware and configuration. Old equipment, unsupported firmware or poor settings can contribute to instability and security issues.

If you are replacing hardware, choose equipment based on the property and network requirements rather than simply buying the router with the largest number printed on the box.

7. Separate coverage problems from device problems

If one phone or laptop performs poorly while everything else works normally, the device itself may be involved. Check its Wi-Fi settings, software updates and whether it supports the wireless standards used by the network.

Testing multiple devices in the same location is a useful way to determine whether the room or the individual device is the real issue.

8. Think about your entire property, not just the lounge room

Modern households may rely on Wi-Fi in bedrooms, home offices, garages, outdoor areas and even detached workspaces. The network should be designed around where people actually use it.

9. Use managed Wi-Fi if you do not want to troubleshoot the network yourself

With compatible Alder-managed networking, our team can assist with supported router and Wi-Fi configuration, connection status, firmware and remote diagnostics where available.

That changes the support model from “the NBN line is online, check your router” to a broader view of the internet service and the network behind it.

10. Upgrade the internet plan only when the connection is actually the bottleneck

If tests show the router receives the full service speed but Wi-Fi falls away around the house, fix the wireless network first. If every device is constrained even when connected close to the router or by Ethernet, then a faster NBN tier may be appropriate.
