Next-Gen WiFi Speed

RT-AX55 is a 2x2 dual-band WiFi router that provides 80MHz bandwidth and 1024-QAM for dramatically faster wireless connections. With a total networking speed of about 1800Mbps — 574Mbps on the 2.4GHz band and 1201Mbps on the 5GHz band — RT-AX55 is 1.5X faster than 802.11ac 2x2 dual-band routers.

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 WiFi 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 WiFi 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 WiFi experience.

Better Battery Life for Your Devices

Target Wake Time (TWT) allows RT-AX55 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.

WiFi that Goes Farther

With the latest 802.11ax WiFi standard featuring OFDMA technology, RT-AX55 provides increased WiFi 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 WiFi connection throughout your home.

Protection for your Home Network

RT-AX55 has lifetime free AiProtection Classic, powered by Trend Micro with automatic, regularly updated security signatures to protect your devices and personal data from internet threats. This strong security offers parental controls, including the ability to block specific websites and mobile app types.

Powerful Whole-home WiFi System. The Way You Want.

In most cases, your RT-AX55 can deliver smooth, reliable WiFi to every part of your home. But WiFi 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 WiFi 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 WiFi you can rely on — for all your devices, all the time!

I use this as a second router for my Starlink connection. I have a 70m Ethernet cable coming from the shed where Starlink
Is set up, and this is connected to the end of that in the house. Gives a great signal and was very easy to set up.

Works but slow. Massive latency with high "Ping" (700+ms) absolutely unusable for gaming. The wifi is hopelessly slow even when it's in view 6m away. (Not my computers, I've tried it at my friends and it worked fine) I've now connect my computers to it with Ethernet cables just to get it to work when gaming. Works ok when watching movies when high Pings are not an issue. Would also randomly disconnect with the TV. So I've just hooked it up with Ethernet cable too.
Absolute garbage, do not buy.

Good price on sale, warranty was wrong on Asus website after product registration and contacted Asus after asking around here. They mentioned that the warranty shown there is based on manufacturing date and due to the upgrading of the website they cannot change it on the backend. However they will honour 3 years from date of purchase if any issues. Which is great and fast customer service.

If using from Australia, try to set to DHCP for WAN connection type. Works very well with HFC NBN, increasing the range quite decently to my entire house now.

Asus app also lets you customize many options and looks very interesting.

I had to change the settings from PPPoe to automatic ip which took about 30 mins as I thought it was plug and play. Other than that, works well for now.

Delivery was late. I received it almost 4 weeks after purchasing. Had to get the seller to raise a log with AusPost
