The TP-Link Deco P9 is a mesh Wi-Fi system aimed at eliminating Wi-Fi dead zones in medium-sized homes. Released in 2019, it utilizes a combination of Wi-Fi and Powerline technology to deliver a more extensive and stable internet connection compared to traditional routers. While not the most cutting-edge offering, the Deco P9 remains a relevant option for budget-conscious users.

Pros:

  • Affordable Mesh Solution: Compared to newer Wi-Fi 6 mesh systems, the Deco P9 is a significantly cheaper option. This makes it ideal for users looking to upgrade from a single router without breaking the bank.

  • Good Coverage with Powerline: The Deco P9 utilizes a combination of Wi-Fi and Powerline technology. Powerline uses your home’s electrical wiring to transmit data, effectively bypassing obstacles that weaken Wi-Fi signals. This delivers better coverage, particularly in homes with thick walls or complex layouts.

  • Easy Setup and Management: Setting up the Deco P9 is a breeze using the TP-Link Deco app. The app guides you through the process and allows for ongoing network management, including guest network creation, parental controls, and device prioritization.

  • Reliable Performance: While not boasting the fastest speeds on the market, the Deco P9 provides consistent and reliable Wi-Fi performance for everyday tasks like browsing, streaming, and video conferencing.

  • Flexible Configuration: The Deco P9 can function in two modes. In mesh mode, it creates a unified Wi-Fi network throughout your home. Alternatively, it can be used in access point mode to extend the range of your existing router.

Cons:

  • Limited Speed (Wi-Fi 5): The Deco P9 utilizes the older Wi-Fi 5 (802.11ac) standard. This translates to slower speeds compared to newer Wi-Fi 6 mesh systems, which can be a drawback for users with gigabit internet plans or those who heavily rely on high-bandwidth activities like online gaming.

  • No Multi-Gigabit Support: The Deco P9 lacks multi-gigabit wired ports, which are becoming increasingly common in high-end mesh systems. This limits its future-proofing capabilities for users anticipating significant internet speed upgrades.

  • Larger Units: Compared to some newer mesh systems, the Deco P9 units are a bit bulkier. While not a major concern for everyone, it’s a factor to consider if aesthetics and space are a priority.

Who Should Consider the TP-Link Deco P9?

This mesh system is ideal for users who:

  • Have a medium-sized home (up to 4,000 sq. ft.) with Wi-Fi dead zones.
  • Prioritize affordability over cutting-edge features.
  • Value a simple setup process and user-friendly app.
  • Have an existing internet plan that doesn’t exceed gigabit speeds.

Who Should Look Elsewhere?

Users with:

  • Large homes exceeding 4,000 sq. ft.
  • Gigabit or multi-gigabit internet plans seeking maximum speed potential.
  • A strong preference for the latest Wi-Fi 6 technology.
  • Limited space and prioritize a more compact design.

Overall

 the TP-Link Deco P9 is a competent mesh Wi-Fi system that offers good value for budget-conscious users in medium-sized homes. Its strength lies in its ease of use, reliable performance, and Powerline technology for tackling Wi-Fi dead zones. However, users seeking the fastest speeds or those with future-proof aspirations might be better served by newer Wi-Fi 6 mesh systems.
