It is fast and versatile enough for most purposes, particularly for those who plan to use wired connections. This post explores what makes this mesh system an intriguing choice for budget-conscious users.
💲 What makes the ZenWiFi BD4 a budget-friendly option? – Low Price, Big Coverage
The Asus ZenWiFi BD4 stands out primarily for its aggressive pricing. A two-station system costs £180, while a three-station system is priced at £244. The system is built to cover a large area. With two units, it promises a coverage area of 470 square meters. A three-unit setup expands this to 600 square meters.
📶 How does its Wi-Fi performance compare? – A Look at the Speed and Connectivity
The ZenWiFi BD4 is a dual-band 2.4GHz/5GHz mesh router. It offers up to 2.9Gbits/sec on the 5GHz band and 700Mbits/sec on the 2.4GHz band. However, a portion of its bandwidth is used to pass data between the mesh units, which reduces the speed available to devices. The system does not support the 6GHz frequency range. Each station is equipped with a pair of 2.5Gbits/sec Ethernet sockets, which allows for fast wired connections.

- Configurable QoS (Quality of Service).
