Instead of creating a separate wireless network, it works with compatible Deco units to provide one unified connection throughout the home. This helps devices move between coverage areas with less interruption as users walk from room to room.\u003C\u002Fp>\n  \u003Cp>Using dual-band Wi-Fi 5 technology, the Deco M3W provides combined wireless speeds of up to AC1200: 867 Mbps on the 5 GHz band and 300 Mbps on the 2.4 GHz band under ideal conditions. Actual performance depends on the main Deco unit, internet service, building materials, interference, device capability, and network traffic.\u003C\u002Fp>\n  \u003Cp>The unit is suitable for homes, apartments, home offices, and small workspaces where a central router does not provide reliable coverage in bedrooms, hallways, or upper floors. It can help improve connectivity for smartphones, laptops, streaming devices, smart-home products, and other wireless equipment.\u003C\u002Fp>\n  \u003Cp>Setup is managed through the TP-Link Deco app. The app guides users through adding the extender, selecting a location, and optimizing the mesh system. For best results, place the unit within dependable range of an existing Deco node rather than in the dead zone itself. The compact wall-plug design also avoids the need for a separate shelf or power cable.\u003C\u002Fp>\n\n  \u003Ch2>TP-Link Deco M3W Specifications and Features\u003C\u002Fh2>\n  \u003Cul>\n    \u003Cli>\u003Cstrong>Product type:\u003C\u002Fstrong> Whole-home mesh Wi-Fi add-on unit and Deco range extender.\u003C\u002Fli>\n    \u003Cli>\u003Cstrong>Wireless standard:\u003C\u002Fstrong> Wi-Fi 5, including IEEE 802.11ac, 802.11n, 802.11a, 802.11b, and 802.11g compatibility.\u003C\u002Fli>\n    \u003Cli>\u003Cstrong>Wireless class:\u003C\u002Fstrong> AC1200 dual-band Wi-Fi.\u003C\u002Fli>\n    \u003Cli>\u003Cstrong>5 GHz speed:\u003C\u002Fstrong> Up to 867 Mbps using 802.11ac.\u003C\u002Fli>\n    \u003Cli>\u003Cstrong>2.4 GHz speed:\u003C\u002Fstrong> Up to 300 Mbps using 802.11n.\u003C\u002Fli>\n    \u003Cli>\u003Cstrong>Mesh technology:\u003C\u002Fstrong> Works with compatible Deco units to create one seamless network.\u003C\u002Fli>\n    \u003Cli>\u003Cstrong>Backhaul:\u003C\u002Fstrong> Supports optional Ethernet backhaul where the network design and compatible equipment allow it.\u003C\u002Fli>\n    \u003Cli>\u003Cstrong>Antennas:\u003C\u002Fstrong> Two internal antennas.\u003C\u002Fli>\n    \u003Cli>\u003Cstrong>Typical coverage guidance:\u003C\u002Fstrong> Intended to extend coverage in approximately one- to two-bedroom areas, depending on construction and placement.\u003C\u002Fli>\n    \u003Cli>\u003Cstrong>Dimensions:\u003C\u002Fstrong> Approximately 69 × 35 × 124 mm.\u003C\u002Fli>\n    \u003Cli>\u003Cstrong>Management:\u003C\u002Fstrong> Configuration and monitoring through the TP-Link Deco mobile app.\u003C\u002Fli>\n    \u003Cli>\u003Cstrong>Placement:\u003C\u002Fstrong> Direct wall-outlet installation without a separate power adapter.\u003C\u002Fli>\n  \u003C\u002Ful>\n  \u003Cp>AC1200 is a combined theoretical link-rate classification, not a guarantee of internet speed.
