RT-BE88U DUAL-BAND WIFI 7 ROUTER | Unparalleled 34G Wired Performance

Dominate your network with the ultimate performance for those who demand the absolute best, today and tomorrow. ASUS RT-BE88U, the successor to the legacy RT-AX88U, powered by next-level WiFi 7, delivers an astounding 7200 Mbps for your connected living. The RT-BE88U boasts a monster 34 Gigabit combined capacity. Its killer combination includes a cutting-edge 10 Gigabit SFP+ next gen connection and up to 9 LAN ports, ensuring seamless hardwiring for all your devices and future-proofing your network.

Leap Forward with WiFi 7

WiFi 7 introduces revolutionary features that deliver exceptionally fast speeds, extremely low latency, and enhanced reliability. With these advancements, you can experience unparalleled network performance for gaming, streaming, smart home devices, and more. WiFi 7 brings all this to the table - and it retains all the congestion-busting tech of WiFi 6, too.

  • Up to 7,200 Mbps
  • Dual-band Multi-link 2.4 Ghz + 5 GHz
  • Up to 1.2x Faster with 4K-QAM


Impressive Throughput

RT-BE88U achieves blazing-fast wireless speeds of up to 7,200 Mbps, ensuring seamless streaming, gaming, and data-intensive tasks. Whether you're binge-watching your favorite shows or collaborating in a virtual meeting, this router delivers.

Dual-Band Multi-Link

Dual-band Multi-Link Operation (MLO) intelligently manages traffic and aggregates bandwidth across both the 2.4 GHz and 5 GHz bands, reducing congestion and maximizing throughput. Connecting to multiple bands enables seamless switching where your data will be allocated to the most suitable band to reduce latency.

4K-QAM Data Transmission

4K-QAM takes data transmission rates to new heights. By packing signals more densely, 4K-QAM allows you to transmit more information within the same bandwidth. Imagine upgrading from a standard delivery truck to a massive cargo carrier: with 4K-QAM, your data packets can carry more "merchandise" (data) in each transmission. Compared to WiFi 6, 4K-QAM can improve data transmission rates by up to 20%, meaning faster downloads, smoother streaming, and quicker uploads.

Extreme Wired Performance

The RT-BE88U offers incredible network flexibility. It comes with dual 10 Gigabit ports, four 2.5 Gigabit ports and four Gigabit ports that combine for up to 34 Gigabit WAN and LAN capacity. It also supports WAN/LAN aggregation, giving you the flexibility to provide massive bandwidth to connected devices or take advantage of ultra-high-speed internet connections.

  • Up to 34G WAN & LAN capacity
  • 10G SFP+ WAN/LAN port
  • Up to 9 LAN Max connectivity


Dual 10 Gb Ports

The RT-BE88U has two powerful 10 Gigabit ports: a 10 Gigabit SFP+ port and a 10 Gigabit WAN/LAN Ethernet port. These support both fiber and copper 10 Gigabit connections for future-proof connectivity.

Flexible WAN/LAN Options

The router offers versatile WAN inputs, including a 10 Gigabit WAN/LAN port and 2.5 Gigabit WAN/LAN port. Its advanced AI detection* features streamline setup for efficiency.

4G and 5G Mobile Tethering

Connect your phone to the router's USB port for alternative primary or backup internet using 4G or 5G data.

VLAN

Simplify home network management by organizing devices into logical groups using VLANs, making it easier to apply specific security rules and manage access.
