The Mercusys MB520-5G is a 5G router with AX3000 dual band Wi-Fi 6. Mercusys rates its 5G modem at up to 4.67 Gbps download and 1.25 Gbps upload, with LTE Cat 19 fallback. It adds a 2.5 Gbps WAN/LAN port, a gigabit LAN port, an RJ11 phone port for VoLTE calls and two external antenna ports.

MB520-5G overview

The MB520-5G turns a 5G mobile service into Wi-Fi for home and remote-work setups. Mercusys lists peak rates of 4.67 Gbps download and 1.25 Gbps upload on 5G, and 1.6 Gbps download and 200 Mbps upload on LTE Cat 19. These depend on local 5G or 4G coverage, the data plan, real-time network capacity, client limitations and the environment, and Mercusys adds that the supported bands can vary slightly between regions because of certification. The bands listed on the AU page are 5G n1/n3/n5/n7/n8/n20/n28/n38/n40/n41/n71/n77/n78/n79, LTE-FDD B1/B2/B3/B4/B5/B7/B8/B20/B28/B66, LTE-TDD B38/B40/B41 and WCDMA B1/B2/B5/B8.

Setup needs only a nano SIM and power: the SIM is sold separately and must be activated with no PIN lock, and the Quick Installation Guide explains unlocking. Cellular modes are 5G Preferred, 5G Only, 4G Preferred, 4G Only and 3G Only, and the APN menu includes band search, network search and data roaming. Internal 5G/LTE antennas handle reception, and two external 5G/4G antenna ports accept additional antennas to strengthen the signal. Mercusys suggests the router for homes without fibre, holiday homes, temporary stores, lodging and remote areas.

Wi-Fi is AX3000 dual band Wi-Fi 6 using IEEE 802.11ax/ac/a/b/g/n: 2402 Mbps on 5 GHz with up to 160 MHz channels, and 574 Mbps on 2.4 GHz. Wi-Fi 6 features such as OFDMA, MU-MIMO and 1024-QAM need clients that support them, and the quoted rates are IEEE physical rates rather than delivered throughput. The specifications give a maximum of 256 wireless clients and a recommended limit of 128. Functions include Smart Connect, WPS, a wireless schedule, client statistics, multi-SSID and EasyMesh; Mercusys says EasyMesh links with other vendors can fail on firmware conflicts and that the router is not Wi-Fi EasyMesh certified. WPA-PSK, WPA2-PSK and WPA3-SAE are supported, with guest networks on both bands.

Wired connections include a 2.5 Gbps WAN/LAN port and a gigabit LAN port. In Wireless Router mode the router can use a wired service instead of 5G; Mercusys notes that 2.5 Gbps speeds need a compatible plan and equipment, and that the 2.5 Gbps and gigabit ports cannot both be configured as WAN ports at the same time. An RJ11 phone port lets you connect a landline handset for calls over VoLTE while the internet stays connected. Mercusys's overview also describes a VPN Server function for reaching home devices such as NAS, printers and cameras remotely.

Management is through the Mercusys app or web interface, with cloud firmware upgrades and remote management. Other listed features are data statistics and a data limit, SMS, parental controls with time control and website filtering, QoS, DynDNS and NO-IP, NAT forwarding, IPv6, an SPI firewall, IPv6 firewall, service filtering, access control and IP and MAC binding, TR-069, a reboot schedule and traffic statistics. The desktop unit measures 190 x 130 x 69.7 mm, uses a 12 V / 2 A supply, has WPS and reset buttons with power, internet, phone and three signal LEDs, and operates from 0 to 40 °C.
