Verdict

The Netgear EX6400 is an AC1900 dual-band WiFi mesh extender that delivers speeds up to 1.9Gbps and expands wireless coverage by up to 2,100 square feet for 35 devices. Its main characteristics include patented FastLane technology for simultaneous dual-band high-speed connections, MU-MIMO for multi-device streaming, and a dedicated Gigabit Ethernet port for wired connectivity. Pros include seamless smart roaming using a single WiFi name (SSID), universal compatibility with any standard router, and a convenient wall-plug design with easy push-button WPS setup. However, potential cons include a bulky chassis that may block adjacent power outlets and occasional connectivity issues where the device stays connected to the router but fails to load data for client devices.
