What we like about Linksys RE6400

  • Simple and quick setup process, especially when using the WPS button or the intuitive web interface
  • Effectively eliminates dead zones and provides a strong, stable signal in previously hard-to-reach areas
  • Dual-band support (2.4 GHz and 5 GHz) allows for flexibility and better performance for various devices
  • Spot Finder technology helps users find the optimal physical placement for the extender
  • Compact and sleek design that typically does not block the second outlet in a standard wall socket
  • Includes a Gigabit Ethernet port for reliable wired connections to devices like gaming consoles or Smart TVs

What we don't like about Linksys RE6400

  • Significant speed reduction compared to the main router, which is a common limitation of Wi-Fi extenders
  • The web-based administration interface can be sluggish and slow to respond when saving settings
  • Occasional connectivity issues, including dropped signals during streaming or high-bandwidth activities
  • Initial setup can sometimes be tricky or require multiple attempts if WPS fails to sync both bands at once
  • Front LED indicator can be inconsistent, sometimes showing a weak connection status even when performance is stable
  • Performance on the 2.4 GHz band is often cited as disappointing compared to the faster 5 GHz band

Verdict

The Linksys RE6400 is an AC1200 dual-band Wi-Fi range extender designed to eliminate dead zones across up to 7,500 square feet, offering combined speeds of up to 1.17 Gbps (300 Mbps on 2.4 GHz and 867 Mbps on 5 GHz). It features Cross-Band and Beamforming technologies to optimize data transfer, along with a single Gigabit Ethernet port for high-speed wired connectivity. Main pros include a simple setup via WPS or the mobile-friendly Spot Finder technology for optimal placement, and its compact wall-plug design that doesn't block adjacent outlets. However, some users have noted that the device can run hot during operation and the web management interface may experience sluggish response times.
