Last updated: 15 August 2026<\/p>\n\n\n

Decided on mesh?<\/strong> Our best mesh WiFi systems in Australia<\/a> guide has the current picks with live checked prices, from the $499 default answer up to WiFi 7.<\/p>\n\n\n\n\n

If the Wi-Fi is weak in one room and fine everywhere else, a range extender will probably sort it out for under $150. If it is patchy through most of the house, an extender will not save you and you want a mesh system. That is the short answer.<\/p>\n\n\n\n

The bit most comparisons skip is that a lot of Australian homes do not have a coverage problem at all. They have a modem problem. It is the cheapest thing to check, it takes about ten minutes, and it comes up constantly in the reviews people leave on this site. So this article covers how each device actually works, how to tell which situation you are in before you spend anything, and what the two options cost here in 2026.<\/p>\n\n\n\n

How each one actually works<\/h2>\n\n\n\n

This is the part that explains everything else, so it is worth thirty seconds.<\/p>\n\n\n\n

\"Diagram
How the two approaches differ. The extender relays on the same radio it serves your devices with. The mesh nodes talk to each other on a separate channel.<\/figcaption><\/figure>\n\n\n\n

A range extender listens to your router and rebroadcasts what it hears. On a cheap single band unit, one radio does both jobs, and it can only do one at a time. That is where the old rule about extenders halving your speed comes from, and it is basically true. Dual band and tri band extenders use a separate radio for the link back to the router, which gets rid of most of the loss. They cost a bit more and they are worth it.<\/p>\n\n\n\n

A mesh system does the same trick properly. The nodes keep a dedicated link between themselves, either on their own radio band or over an Ethernet cable if you have one running through the house, so the speed that reaches the far end of the house is close to what the modem is putting out. They also present one network name, and the system decides which node your phone should be on rather than leaving your phone to work it out.<\/p>\n\n\n\n

That second point matters more than people expect. With an extender your laptop will happily cling to the weak original network at two bars while a much stronger extender signal sits there unused. Most extenders sold now can be set to use the same network name as your router, which helps, and it is worth digging through the app to turn that on. Look for something called One Mesh, Same SSID or FastLane. Devices still do not always pick the strongest of the two, but it is far better than the default.<\/p>\n\n\n\n

Before you spend anything, check it is really coverage<\/h2>\n\n\n\n

Run our speed test<\/a> three times on the same device: once standing right next to the modem, once in the middle of the house, and once in the room that annoys you. Same device, same time of day, no one streaming in the background. Write the numbers down.<\/p>\n\n\n\n

What you see<\/th>What it means<\/th>What to do<\/th><\/tr><\/thead>
Slow in every room, including next to the modem<\/td>Not a Wi-Fi problem. Either the connection or the plan<\/td>Neither device will help. See what to do if your NBN stops working<\/a><\/td><\/tr>
Good next to the modem, poor in one room<\/td>Coverage, one room<\/td>An extender is a reasonable first try<\/td><\/tr>
Good next to the modem, patchy in most rooms<\/td>Coverage, whole house<\/td>Mesh. An extender only moves the problem<\/td><\/tr>
Fine in the morning, terrible at 8pm in every room<\/td>Congestion, not coverage<\/td>Look at the plan and the provider, not the hardware<\/td><\/tr><\/tbody><\/table>
Three tests will tell you more than any product review.<\/figcaption><\/figure>\n\n\n\n

That last row catches a lot of people. If the speed collapses every evening no matter where you stand, you are looking at a busy hour problem on the connection itself, and no amount of Wi-Fi hardware fixes that. Our guide on what slows down your internet<\/a> goes through the other causes.<\/p>\n\n\n\n

The modem your provider sent you is often the real problem<\/h2>\n\n\n\n

We have 1,240 reviews on this site going back to 2004, and 163 of them mention the modem or the router. It is rarely a compliment. What stands out is that it is not one bad provider, it is all of them, cheap and expensive alike.<\/p>\n\n\n\n

“Supplied modem is junk. The supplied modem just isn’t up to par. Can’t support multiple wifi devices.”<\/p>Superloop customer, June 2022<\/cite><\/blockquote>\n\n\n\n

“The modem supplied by Aussie Broadband has below average WIFI capacities.”<\/p>Aussie Broadband customer, April 2019<\/cite><\/blockquote>\n\n\n\n

“Connection randomly drops out, bad quality provided router.”<\/p>TPG customer, April 2021<\/cite><\/blockquote>\n\n\n\n

Providers buy modems in bulk to hit a price, and the Wi-Fi side is where they save money. A five year old free modem sitting in a media cabinet is doing a fair impression of a coverage problem. This is also why mesh fixes so much: it does not just add coverage, it takes the Wi-Fi job away from that modem entirely.<\/p>\n\n\n\n

If you want to keep it cheap, a decent standalone router on its own is sometimes all you need, and our BYO modem setup guide<\/a> covers how to swap it over without breaking anything.<\/p>\n\n\n\n

So which one should you buy?<\/h2>\n\n\n\n
