What we like about TP-Link TL-WA855RE

  • Easy setup process, especially when using the TP-Link Tether app or WPS button
  • Compact and minimal wall-plug design that doesn't block adjacent outlets
  • Integrated Ethernet port allows for connecting wired-only devices like Smart TVs or older PCs
  • Helpful intelligent signal indicator LEDs (Blue/Red) to find the best placement
  • Very affordable price point for basic home Wi-Fi dead-zone coverage
  • Adjustable external antennas help with signal positioning and stability

What we don't like about TP-Link TL-WA855RE

  • Limited to the 2.4GHz band only, which can cause interference and slower speeds in crowded areas
  • Significant speed reduction (often 50% or more) compared to the main router's speed
  • Mixed range performance; some users find it ineffective beyond 50-75 feet or through thick walls
  • Reported reliability issues, including random disconnections or the device failing after several months
  • Maximum theoretical speed of 300Mbps is often much lower in real-world usage
  • Not recommended for multi-story homes where a mesh system would be more effective

Verdict

The TP-Link TL-WA855RE is a compact N300 Wi-Fi range extender designed to eliminate dead zones by supporting wireless speeds up to 300Mbps on the 2.4GHz band. It features two external antennas with MIMO technology for improved stability, a 10/100Mbps Ethernet port for connecting wired devices, and dual-mode functionality allowing it to operate as either a repeater or a dedicated Access Point. Key pros include its easy setup via the WPS button or Tether app, a useful intelligent signal indicator for optimal placement, and a power scheduling feature for energy efficiency. However, its main drawbacks are that it lacks 5GHz dual-band support, utilizes a slower Fast Ethernet port rather than Gigabit, and may experience significant speed reductions common to single-band extenders.
