WiFi 7 Tri-Band – BE9400, Up to 9400 Mbps Combined, 320 MHz Channels

The ASUS RT-BE90U is a BE9400-class tri-band router running WiFi 7 (802.11be) across three bands:

BandSpeedTransmit/Receive
6 GHzUp to 5764 Mbps2×2
5 GHzUp to 2882 Mbps2×2
2.4 GHzUp to 688 Mbps2×2

Combined throughput adds up to 9400 Mbps (688 + 2882 + 5764). The router supports 320 MHz channel bandwidth on the 6 GHz band and 4096-QAM encoding, which together increase single-band transmission speed by 2.4× compared to the previous generation. OFDMA and universal beamforming are both onboard.

Six external antennas handle the tri-band signal, with MU-MIMO and Airtime Fairness managing multiple connected devices.

Multi-Link Operation (MLO) – Simultaneous Multi-Band Connections

MLO lets compatible devices link to multiple bands at the same time instead of picking just one. The result is more stable connections and better data throughput, especially in congested wireless environments.

1.5 GHz Quad-Core Processor, 1GB RAM, 256MB Flash

Running the show is a 1.5 GHz quad-core processor paired with 1 GB RAM and 256 MB Flash storage. This handles routing, QoS, VPN, and AiProtection duties simultaneously.

Quad 2.5G Ethernet Ports – Flexible WAN/LAN Configuration

Wired connectivity on the ASUS RT-BE90U:

  • 1× 2.5 Gbps WAN port
  • 3× 2.5 Gbps LAN ports
  • 1× USB 3.2 Gen 1 port

Traffic through the 2.5G ports gets top priority. The USB port supports file sharing (Samba, FTP, Time Machine), media serving, Download Master, and 4G LTE/5G mobile tethering for failover internet.

AiProtection – Commercial-Grade Network Security

AiProtection provides commercial-grade security without a subscription fee:

  • Router Security Assessment — one-tap scan for vulnerabilities
  • Two-Way IPS — intrusion prevention for both inbound and outbound traffic
  • Safe Browsing — blocks access to known malicious sites

Additional security features include WPA3 Personal and Enterprise, DNS-over-TLS, Let’s Encrypt SSL, SSH access, and a configurable firewall with up to 64 keyword filters, 32 network service filters, and 64 URL filters.

VPN – WireGuard, OpenVPN, IPSec, Instant Guard, VPN Fusion

VPN support is extensive:

  • VPN Server: WireGuard, OpenVPN, IPSec, PPTP
  • VPN Client: WireGuard, OpenVPN, L2TP, PPTP
  • VPN Fusion — run VPN and regular traffic simultaneously on different devices
  • Instant Guard — one-tap VPN from the ASUS Router app
  • Surfshark and NordVPN integration

Smart Home Master – 3 SSIDs, IoT Management, Parental Controls

Smart Home Master supports up to three SSIDs for segmenting IoT devices, personal devices, and guest access. There’s also a Guest Network (up to 3 rules across 2.4 GHz + 5 GHz bands) with its own encryption options.

Parental Controls include web and app filters, time scheduling, customised internet schedules, and Safe Browsing — supporting up to 64 parental control profiles.

AiMesh – Whole-Home Mesh Networking

The RT-BE90U works as either a primary AiMesh router or an AiMesh node, enabling seamless roaming across multiple ASUS routers. It also operates in Repeater, Access Point, Media Bridge, and Wireless Router modes.

Traffic Control – Adaptive QoS, Bandwidth Limiter, Traffic Analyzer

Network management tools include:

  • Adaptive QoS and Traditional QoS
  • Bandwidth Monitor and Bandwidth Limiter (up to 32 rules)
  • Real-time, wired, and wireless traffic monitors
  • Traffic Analyzer with daily, weekly, and monthly analysis periods plus website history

WAN Features – Dual WAN, Mobile Tethering, Port Forwarding

WAN connectivity supports Dual WAN for failover or load balancing, 4G/5G Auto Mobile Tethering, and multiple connection types (PPPoE, Static IP, Automatic IP, L2TP, PPTP, IPSec). Port forwarding handles up to 64 rules, port triggering up to 32 rules, and DDNS and DMZ are available. NAT passthrough covers IPSec, L2TP, PPTP, SIP, H.323, and RTSP.
