What we like about Netgear EX6400

  • Easy and quick setup process, especially when using the Nighthawk app or WPS button.
  • Significant improvement in Wi-Fi range, effectively eliminating dead zones in large homes or outdoor areas.
  • Fast and stable connection speeds, with some users noting performance exceeding 60Mbps.
  • Seamless mesh technology allows for a single network name (SSID) throughout the house.
  • Versatile functionality with a built-in Gigabit Ethernet port for wired devices and an Access Point mode toggle.
  • Good value for money compared to more expensive mesh systems.

What we don't like about Netgear EX6400

  • Mixed reliability with some reports of connection drops and units requiring periodic restarts.
  • The required Nighthawk app and account creation for setup are frustrating for some users.
  • Technical support is only free for the first 90 days, which critics find inadequate for a one-year warranty product.
  • Occasional compatibility issues with specific ISP routers or older devices.
  • Bulkier wall-plug design can partially block adjacent power outlets.

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.
