    TP-Link AXE5400: One minute review

    Asus RP-AX58: Specifications

    Wi-Fi: Wi-Fi 6E
    Wi-Fi Speed: 5.4Gbps
    Ports: 1x Gigabit Ethernet
    Antennae: 4
    Dimensions: 348 x 106 x 80mm

    Wi-Fi 6E, which the Asus RP-AX58 features, is a bit like the missing link of the Wi-Fi family. It was the first version of Wi-Fi technology to introduce the high-speed 6.0GHz frequency band – in addition to the existing 2.4GHz and 5.0GHz bands used by previous generations of Wi-Fi. However, it never really took off as many people had only just upgraded to Wi-Fi 6, and it wasn’t long before the absurdly fast Wi-Fi 7 came along and made poor old 6E look a bit irrelevant.

    The advantage of that, though, is that you can now pick up a high-performance range extender that uses Wi-Fi 6E at a pretty competitive price.

    We liked TP-Link’s BE3600 range extender thanks to its ease of use and installation, but its dual-band Wi-Fi 7 performance was actually fairly modest, with a top speed of 3.6Gbps. The AXE5400 (model number RE815XE) is around the same price as the BE3600, but the use of Wi-Fi 6E means that it can provide tri-band Wi-Fi performance and a speed of 5.4Gbps that should be more than adequate for use with most home broadband services.

    TP-Link AXE5400: Price And Availability

    • How much does it cost? $139.99/£119.14
    • When is it available: Now
    • Where can you get it: US, UK

    The AXE5400 costs $139.99/£119.14, which is slightly less expensive than the TP-Link BE3600 with Wi-Fi 7, even though the tri-band Wi-Fi 6E used by the AXE5400 actually provides stronger performance with a top speed of 5.4Gbps.

    It’s not currently on sale in Australia, though, where it looks like TP-Link is skipping a generation and going from an older Wi-Fi 6 model to the new BE3600 with Wi-Fi 7 instead.

    TP-Link AXE5400: Design

    • Big, bulky design
    • Four external antennae
    • Easy-to-use app

    It’s safe to say that the AXE5400 is not going to quietly and unobtrusively blend into your home décor.

    Its four large external antennae make it one of the biggest and bulkiest range extenders we’ve come across, and with the antennae fully extended the AXE5400 measures a full 348mm high, 106mm wide and 80mm deep (including the plug section that is inserted straight into a mains power socket).

    Sign up for breaking news, reviews, opinion, top tech deals, and more.

    In fact, it’s so large that it actually blocked an adjacent power socket when we set it up in our offices. There’s also a series of status indicator lights on the front panel, which are useful when setting up the AXE5400, but also mean that it may take up even more space in order to keep the front of the unit clear and visible.

    The bulky design does serve a purpose though, as the large antennae help to beam the range extender’s tri-band Wi-Fi signal far and wide, and ensure that it obliterates any annoying deadspots in your home. There’s an Ethernet port on the right-hand side of the unit to provide a wired connection too – although, of course, the AXE5400 still relies on Wi-Fi to connect to your main broadband router.

    TP-Link AXE5400: Features

    • Simple installation
    • Helpful status indicators
    • Plugs directly into mains power socket

    It may not support the latest Wi-Fi 7, but the AXE5400 includes plenty of features that enable it to provide strong Wi-Fi performance, and also to help people who may not have used a range extender before.

    The use of tri-band Wi-Fi 6E allows the AXE5400 to broadcast a Wi-Fi signal on three separate frequency bands. The 2.4GHz and 5.0GHz bands provide compatibility with older PCs and mobile devices, while the high-speed 6.0GHz band boosts the Wi-Fi performance to a healthy 5.4Gbps – which is significantly faster than dual-band range extenders that use Wi-Fi 7, such as TP-Link’s BE3600, or the Asus RP-BE58.

    And, as mentioned, there’s a Gigabit Ethernet port on the AXE5400 to provide a wired connection as well. It also provides a feature called ‘adaptive path selection’ – often just called ‘roaming’ by most other manufacturers – which can monitor a laptop or mobile device as you move from room to room, and decide when to hand the Wi-Fi connection back to your main router in order to maintain the best performance.

    Like most range extenders, the AXE5400 will work with routers from any manufacturer, but it also supports TP-Link’s OneMesh system, which allows it to be used as part of a wider mesh networking system if you already own a TP-Link router with OneMesh.

    It’s easy to use too (although the annoying Christmas ads that seemed to pop up every now and then within the app were pretty shameless). The TP-Link Tether app can automatically detect the Wi-Fi signal from the AXE5400 and guide you through the process of connecting to the three different frequency bands.

    You can use the same name and password as your main network from your broadband router, or create a new name and password just for the AXE5400. There’s even a signal test within the app to help you find the best spot to place the AXE5400 in order to deal with any deadspots in particular rooms within your home. And, for more advanced users, there’s a web browser interface that provides more detailed control over your network settings.

    TP-Link AXE5400: Performance

    • Tri-band Wi-Fi 6E
    • 5.4Gbps Wi-Fi
    • 1x Gigabit Ethernet

    Our offices are a good place to test range extenders, as we have one office towards the back of the building that does suffer from a very noticeable Wi-Fi deadspot – which is usually managed with the use of some PowerLine adaptors to provide a wired network connection instead.

    20GB Steam Download – 6.0GHz

    Within 30ft, three partition walls: 150Mbps

    Thankfully, though, the AXE5400 dealt with that problem in no time at all, providing a strong Wi-Fi signal on all three frequency bands as soon as I set it up in a hallway just outside that back office.

    The office broadband runs at 150Mbps, and even the slower 2.4GHz band on the AXE5400 managed to hit 140Mbps with the Ookla Speed Test. Steam downloads were a little slower at 110Mbps, but that speed is still in line with the 2.4GHz performance of other range extenders that we’ve tested.

    Switching to the 5.0GHz band immediately boosted performance, hitting the full 150Mbps with both the Ookla and Steam tests. And, of course, the fastest 6.0GHz band had no trouble maintaining those speeds as well.

    If you only have older PCs or mobile devices that use Wi-Fi 5 or 6 on the 2.4GHz and 5.0GHz bands then you may not need a tri-band range extender such the AXE5400.

    But, if you’re able to make use of that 6.0GHz band, then the AXE5400 is a fast, reliable way of getting rid of Wi-Fi deadspots at a more competitive price than newer Wi-Fi 7 models.

    Wi-Fi 6E may be the forgotten member of the Wi-Fi family, but that means you can pick up this tri-band range extender at a very competitive price.

    4.5 / 5

    Design

    The sheer size of the AXE5400 and its four large antenna means that it’s a bit of an eyesore, and may even block an adjacent power socket.

    The four antennae do earn their keep though, providing tri-band Wi-Fi for maximum compatibility with both older and newer PCs and mobile devices.

    4 / 5

    Performance

    Tri-band Wi-Fi and a top speed of 5.4Gbps means that the AXE5400 can even outperform some of its dual-band Wi-Fi 7 rivals.
