Get Your Home Ready for WiFi 6 (802.11ax)

The growing number of connected personal and IoT devices has led to an overall increase in network density that is pushing the limits of the current Wi-Fi standard. The latest 802.11ax standard provides future-proof technologies, higher network efficiency, faster Wi-Fi speeds, greater coverage and improved battery life for connected devices, providing a significantly better networking experience for users.

Next-Gen WiFi Speed

RT-AX58U is a 2x2 dual-band Wi-Fi router that provides 160MHz bandwidth and 1024-QAM for dramatically faster wireless connections. With a total networking speed of about 3000Mbps — 574Mbps on the 2.4GHz band and 2402Mbps on the 5GHz band — RT-AX58U is 2.5X faster than 802.11ac 2x2 dual-band routers2.

Built for Multi-device Households

With a revolutionary combination of OFDMA and MU-MIMO technology, 802.11ax technology provides up to 4X greater network capacity and efficiency in traffic-dense environments. Previous-generation 802.11ac Wi-Fi can only handle one device at a time on each network channel, which is an inefficient use of available bandwidth. OFDMA support in the 802.11ax Wi-Fi standard divides each channel into small sub-channels, allowing signals from multiple devices* to be bundled together and transmitted simultaneously, reducing latency for a smoother, more responsive Wi-Fi experience.

802.11ac OFDM

Bandwidth wasted - Higher latency

802.11ax OFDMA

Bandwidth fully utilized - Lower latency

Better Battery Life for Your Devices

Target Wake Time (TWT) allows RT-AX58U to schedule designated intervals for devices to transmit data. This allows them to sleep when there is no need to wait for a router signal, reducing power consumption by up to 7X for significantly improved battery life*.

Without Target Wake Time (802.11ac)

Higher Device Power Consumption

With Target Wake Time (802.11ax)

7X better battery life for client devices

Wi-Fi that Goes Farther

With the latest 802.11ax WiFi standard featuring OFDMA technology, RT-AX58U provides increased Wi-Fi signal range and better coverage by dividing each channel into smaller sub-channels. These sub-channels have a smaller bandwidth that enables them to travel up to 80% farther1, resulting in a better Wi-Fi connection throughout your home*.

Commercial-grade Security for your Home Network

RT-AX58U has lifetime free AiProtection Pro, powered by Trend Micro with automatic, regularly updated security signatures to protect your devices and personal data from internet threats. This strong security offers advanced parental controls, including the ability to block specific websites and mobile app types.

The Latest WPA3 Network Security

The next generation of Wi-Fi security, bringing new capabilities to enhance Wi-Fi protections in personal and enterprise networks. Building on the widespread adoption of WPA2 over more than a decade, WPA3 adds new features to simplify Wi-Fi security, enable more robust authentication, and deliver increased cryptographic strength for highly sensitive data markets.

Powerful Whole-home Wi-Fi System.

The Way You Want.

In most cases, your RT-AX58U can deliver smooth, reliable Wi-Fi to every part of your home. But Wi-Fi coverage can be affected by many factors — room layout, construction materials, and even furnishings. ASUS AiMesh is an innovative new router feature that fixes these problems: it creates a whole-home Wi-Fi network using multiple ASUS routers. AiMesh is powerful, flexible and you can use a mix of ASUS router models — protecting your investment! AiMesh gives you time-saving central control, and seamless roaming capability. AiMesh is Wi-Fi you can rely on — for all your devices, all the time!

  • Turn your ASUS routers into whole-home Wi-Fi system with a simple firmware update
  • Mix and match preferred models from selected ASUS routers
  • Create a Wi-Fi network with either a single SSID or multiple SSIDs
  • All router features works across the entire Wi-Fi system

1. The data refers to uplink OFDMA.

2. ac data refers to: 40MHz / 256QAM on 2.4GHz band and 80MHz / 256QAM on 5GHz band. ax data refers to: 40MHz / 1024QAM on 2.4GHz band and 160MHz / 1024QAM on 5GHz band

* To benefit from 802.11ax features, the Wi-Fi client needs to be 802.11ax capable.

** Actual data throughput and WiFi coverage will vary from network conditions and environmental factors, including the volume of network traffic, building material and construction, and network overhead, result in lower actual data throughput and wireless coverage.

*** Quoted network speeds and bandwidth based on current IEEE 802.11ax specifications. Actual performance may be affected by network and service provider factors, interface type, and other conditions. Connected devices must be 802.11ax-compatible for best results.

Great DIY mesh networking option 7/9/2020 8:28:12 AM

Pros: I bought two of these routers to modernize my network. On the main one, connected to my cable modem, I'm running Asuswrt-merlin. Merlin runs flawlessly on it. The routers perform quite well. My home network has two smart TVs which get network access from powerline ethernet as well as two wireless security cameras constantly streaming 1080p video at 30 FPS. Setting up a mesh with two AX3000 routers (connected by CAT-7 ethernet) has led to consistent wireless performance despite the bandwidth drain of the wireless cameras.

Cons: The routers are a bit pricey for the hardware inside, but are probably still the best option for running open source firmware on an 802.11ax/WiFi 6 router.

Overall Review: I'd recommend these to anyone looking to move to WiFi 6 who is able to understand that paying for a high end WiFi 6 router really isn't worth it at this time. As a bonus, they run Asuswrt-merlin very well.

Fast 3/8/2020 4:28:26 PM

Pros: I had the D-link DIR-859 before and this Router is much more stable, supports 160hz channel bandwidth which essentially DOUBLES the connection speed to my PC with the Intel WI-FI onboard which supports this feature
And the best feature in my opinion is that if ever you need more coverage, you can buy another ASUS router that supports AI MESH and you have yourself a mesh network, instead of buying expensive kits

Cons: None, the Firmware interface of ASUS is miles better than D-link's

Overall Review: Anyone wanting to jump onto the WI-FI 6 bandwagon on the cheap, this is it
