Verdict

The Buffalo AirStation Extreme AC1200 (WZR-1166DHP) is a dual-band Wi-Fi 5 (802.11ac) router delivering theoretical speeds up to 1.2 Gbps, specifically 866 Mbps on the 5 GHz band and 300 Mbps on the 2.4 GHz band. It features a gigabit WAN port, four gigabit LAN ports, and a high-speed USB 3.0 port for network-attached storage or printer sharing. Key characteristics include Norton ConnectSafe web filtering, parental controls, and a versatile physical switch to toggle between router, access point, and bridge modes. Main pros include fast FAT32 storage throughput, easy mobile-friendly setup, and effective QoS controls for traffic prioritisation. However, cons include a lack of support for NTFS-formatted USB drives, failure in 40 MHz coexistence tests, and the absence of Wi-Fi certification.
