The TP-Link Deco E4 is a whole home mesh Wi-Fi system designed to eliminate dead zones by creating a single, unified network across your living space. Utilizing the Wi-Fi 5 standard, it delivers combined AC1200 speeds, with 867 Mbps on the 5 GHz band and 300 Mbps on the 2.4 GHz band, allowing you to connect up to 100 devices simultaneously. This three-pack provides expanded coverage for larger areas, while the internal antennas and beamforming technology ensure that signals are directed precisely toward your connected gadgets. Each white, cylindrical unit measures 90.7 by 190 mm and features two auto-sensing 10/100 Mbps Ethernet ports for flexible WAN or LAN connections. You can manage the system through the Deco app on Android or iOS, which simplifies the initial setup and gives you access to parental controls for URL filtering and time limits. For added convenience, the system supports Amazon Alexa for voice control and includes MU-MIMO technology to maintain stable connections even when multiple people are streaming or gaming. Security is handled by an SPI firewall and WPA2-Personal encryption to keep your home network protected.
