AX3000 speeds break down to 574Mbps at 2.4GHz and 2,402Mbps at 5GHz. Both of these routers can deliver plenty of speed for most people, but the extra headroom that comes with AX3000 will be good for those that want to do more local networking. And if this change will increase your quality of life anyway... take your time and look for the product that make you feel safer than now. Only believe than vulnberabilities... will happen. WPA2 is still largely used neverthless has some "incurable flaws" and WPA3 is not a de facto standard. We can see from the graph that two client devices remained under this limit pretty much for the entire duration of the test, but three clients, the WiFi 6 Lenovo Y520 laptops and the WiFi 6E PC did experience a latency spike (the latter did not surprise me). With the exception of one of the two Lenovo laptops, it shouldn’t have a noticeable impact on the streaming experience. And even in the Lenovo laptop case, it does seem to experience it only for 1% of the time. TP-Link AX5400 AX73 – Multi-client stress test using 5 client devices – 1080p streaming (5GHz, 80MHz). The target throughput is 5Mbps. Sure, I can definitely play around with the placement more but so far I have stable and solid connections around the house. The idea is to simulate these types of traffic on all client devices at the same time, and it can be two or more variations at the same time on a single client device (for example, 4K streaming, while the user navigates the web as well, furiously). I didn’t use iperf, but relied on the open-source tools developed by Mr. Jim Salter, netburn which creates the traffic simulations and the net-hydra which runs multiple instances of netburn on the set client devices (it relies on SSH to accomplish it).
Moving forward, I ran the same multi-client test but with the limit set to 25Mbps, essentially simulating what the user will need if it wants the maximum video quality from Netflix. As expected, the performance was a bit worse. TP-Link AX5400 AX73 – Multi-client stress test using 5 client devices – 4K streaming (5GHz, 80MHz). The lower the score, the better. BTW, WiFi 6/6E were just incremental upgrades over WiFi 5 wave 2 (wave 2 implemented MU-MIMO technology, IIRC). WiFi 7 is a much larger step with MLO, potential for real-world +1Gbps WLAN speeds, and 320MHz channel width support. On the rear side of the TP-Link AX73, there are four buttons, one for turning Off/On the LEDs, one for enabling the WPS process, one for turning On/Off the WiFi and the last one is a recessed Reset button (press and hold it for about 10 seconds to return the router to its default settings). Further to the right, there are four LAN ports (all Gigabit), one WAN port (also Gigabit), a Power button and a Power connector. On the right side of the AX73, there’s a single USB 3.0 port for adding a printer or an external storage device. Internal HardwareThe name of the router reflects (more or less) its aggregated bandwidth – a maximum connection speed of 574Mbits/sec on the 2.4GHz band, plus 2,400Mbits/sec in the 5GHz range. To maximise real-world throughout, there’s support for fat 160MHz channels in the 5GHz range, and 2×2 MIMO on both radios, so individual clients can receive two data streams at once. You can manage the AX50 with the TP-Link Tether mobile app for Android and iOS devices, or you can use the web console. Both are easy to use, but the web console offers a few more advanced options such as DHCP Server, NAT Forwarding, Firewall, and IPv6 settings. TP-Link Australia has also kindly provided me their RE605X AX1800 Wi-Fi Range Extender to further boost the signal around our house. It supports Wi-Fi 6 and is a great companion to the Archer AX55 (or any other wireless router you may have at home). With OneMesh network, you can extend your wireless network coverage with ease. We live in a two-storey house and there are spots where things can get a bit flaky occasionally.
Again, only the WiFi 5 client devices went to 25Mbps, the others a bit below it, and the worst offender is once again the WiFi 6E PC which only reached 21.9Mbps. Surprisingly, we see that this client performed a bit better than when the test was run only with the 4K streaming simulation (perhaps we see some features finally starting up and helping the client a bit). TP-Link AX5400 AX73 – Multi-client stress test using 5 client devices – 4K streaming + simultaneous browsing (5GHz, 80MHz). The target throughput is 25Mbps. Multi-Client Stress Test – 2.4GHz This means that users will experience noticeable buffering fairly often. What about the fast web browsing? It always remained below the 1.5s limit, so all is decently well. The question is whether the clients were able to go to the 25Mbps limit and were they able to remain there? TP-Link AX5400 AX73 – Multi-client stress test using 5 client devices – 4K streaming & web browsing (5GHz, 80MHz). The focus is on the web browsing. The lower the score, the better. AX1800 means 574Mbps speeds at 2.4GHz plus 1,201Mbps at 5GHz, though many of your devices won't even be as fast as this. Even this cheaper Wi-Fi 6 router offers faster speeds than solid routers like Eero or Google Wifi. The Wi-Fi 6 AX1800 / AX20 will likely still outperform these routers thanks to some of the features included with Wi-Fi 6 routers, like OFDMA to manage connections to multiple devices more efficiently, along with beamforming, which can improve signal strength further away from the router. With Archer AX55 and RE605X, I haven’t stumbled upon this problem and the smart connect feature seems to be able to connect all my devices around the house to the proper wireless channels accordingly. I know that a lot will say that these tests are not purely objective and yes, the results will differ depending on the amount of interference, the location and the type of client devices. Surely, there are better multi-client tests out there, such as the octoPal, but that will have an impact on the wallet and not many professionals bother with non-enterprise wireless networking devices since the cost is just too high. So yeah, netburn and net-hydra are the best we got for now.A heat sink inside the unit and refined case design keep the system cool which helps in keeping the performance as high and consistent as possible. And during the reviewing period for about 2 weeks and more, I’ve never had any issues with the Archer AX55 or experience any reduced performance or network instability. I’ve somewhat been having troubles occasionally with D-Link’s Wi-Fi 6 routers and Mesh routers ( DIR-X1560 and COVR X-1873) where sometimes my PC/laptops/smartphones get connected to the 2.4GHz instead of 5GHz and giving us a slower network speed.
Great Deal
