Extralink Dynamite - C21 mesh extension module
Extralink Dynamite C21 is a wireless router that allows you to expand an existing Dynamite Mesh system or build a new wireless network from scratch. In both cases, you will experience a stable connection signal and a large coverage area. The unit's flexible configuration enables it to be used interchangeably as a router in a home network or as an access point to extend the reach of a home mesh network.
Extralink Dynamite Mesh System - reliable Mesh Wi-Fi system
The Extralink Dynamite Mesh System features a powerful dual-band Wi-Fi Mesh system that provides internet access to every corner of the home without a drop in signal quality when the end device moves between Mesh devices. The Dynamite Mesh system is designed for devices to connect to each other on a single Wi-Fi network. If one satellite loses connection, the other units automatically and seamlessly reconnect to the internet. The system selects the best path for connections and optimizes the network for speed. Dynamite Mesh supports simultaneous connections in 5 GHz with a maximum throughput of 1733 Mbps and in 2.4 GHz with a maximum speed of 300 Mbps, for a total available throughput of up to 2100 Mbps. Powerful built-in signal boosters provide exceptionally high Wi-Fi coverage and stable throughput, while 4 antennas with 3 dBi for 5 GHz and 2 antennas with 3 dBi for 2.4 GHz deliver even better wireless performance.
