ASUS BD4 Overview

Enhance your home with fast and reliable wireless connections with the ZenWiFi BD4 BE3600 Wireless Dual-Band 2.5G Mesh Wi-Fi System. Comprised of three modules, any of which may be configured as a router or satellite, this white Wi-Fi 7 (802.11be) dual-band wireless mesh system is designed to deliver up to 3.6 Gb/s throughput over the 2.4 and 5 GHz bands with multi-link support, providing smooth 8K video streaming and low latency gaming experiences.

Simply connect either of the two autosensing 2.5G Ethernet ports to your broadband modem to use a module as the router. Otherwise, you can also use them to connect computers, smart TVs, video game consoles, and other wired devices. Connecting ZenWiFi BD4 modules directly to each other through their Ethernet ports creates a wired backhaul that provides reliable connections to overcome thick walls. Supporting up to 6500 square feet of coverage while operating with a single network ID (SSID), this mesh system allows for uninterrupted video streaming, gaming, and web browsing as you move from room to room. Use the ASUS Router app on your Android or iOS device to configure your network, including guest logins and parental controls. You can also connect to your home network via a VPN for additional security when using a public Wi-Fi hotspot.

Fast Wi-Fi
Featuring four internal antennas with support for the 160 MHz channels, the ASUS ZenWiFi BD4 is designed to deliver a total throughput of up to 3.6 Gb/s with compatible devices. Beamforming, MU-MIMO, OFDMA, and dual-band multi-link technologies help to provide strong, long-range connections.
Dual-Band Multi-Link
Multi-Link Operation (MLO) technology enables buffering-free connections by intelligently combining and switching between the 2.4 GHz and 5 GHz bands.
Efficient 4096-QAM Transmission
4K-QAM technology boosts data transmission rates by up to 20% over Wi-Fi 6/6E due to its higher QAM, which packs signals more densely, allowing for more data to be uploaded and downloaded in the same time frame as before.
Easy Setup
Download and install the ASUS Router app to configure, manage, and monitor your network with guest logins and parental controls. You can also use it to generate usage reports for a visual overview of your network.
Effortless Network Segmentation
The powerful and user-friendly Smart Home Master tool allows you to configure multiple SSIDs for easier group and device management. For instance, you can create separate SSIDs for your children's devices, connecting to a VPN through a dedicated subnetwork, and dedicate one secure SSID for your IoT devices.
Commercial-Grade AiProtection Pro
Stay safe with AiProtection Pro powered by Trend Micro, which shields your smart home network with feature-rich controls and management that empower every household member to securely manage their connected devices. Additionally, an advanced encrypted connection protects your online activity and data, keeping them private and secure.
Comprehensive VPN Features
Supporting various VPN protocols including the Wireguard for optimal performance, the ZenWiFi BD4 lets you browse securely on public Wi-Fi or access your home network remotely. Its site-to-site VPN feature even lets you securely connect routers across different networks for seamless data transfers.
Instant Guard
When away from home, ASUS Instant Guard gives you a one-tap secure VPN, and you can easily share it with your family and friends through a URL link to provide the same VPN protection at no additional cost.
Advanced Parental Controls
Built-in, subscription-free, parental controls empower you to balance your kids' digital life by monitoring their activity, scheduling online time, and filtering out unwanted content.

ASUS BD4 Reviews

Great replacement for my eero system

By Pieter
Rated 4 out of 5
Date: 2026-02-24

I bought this ZenWifi 3-pack, along with a handful of RP-BE58s to replace an aging eero system that covers my residence and a handful of outbuildings. I use a wireless ethernet bridge to cover some of the larger gaps. Now that the system is up and running, I have nothing but positive things to say. It was the setup process that knocks it down from 5 stars to 4 stars. Overall, the onboarding was a lot slower and more opaque than the eero equivalent. Just getting the BD4s to link up failed for reasons that weren't explained, but worked on the second try. The "pairing" process took about 10 minutes, which was also surprising to me. In order to get the RP-BE58s onto the mesh, I had to fiddle with the 5ghz settings on the admin interface. Nothing was really explained or spelled out, which was a little bit alarming. The new hardware simply couldn't join the mesh until I had disabled some Wifi7 features and tweaked some frequency settings. That having been said, the performance of the units absolutely blows the eero stuff out of the water. I was able to get better coverage with basically half the hardware. Just keep in mind that this stuff isn't for lightweights. To get it to work right in complex situations, you'll have to roll up your sleeves and do some heavily technical stuff.

Great connectivity and good speed
