To build a network at home or office with minimum effort and cost, the Tenda P200 200Mbps PowerLine Mini Adapter is your choice. In many cases, Ethernet is just not available in places where network connectivity is needed. However, almost every room at home or office has power circuitry, which can be used to extend network connections from your broadband router. Simply plug one P200 that links to a broadband modem/router into the power outlet in one room, and plug another P200 linking to a PC or any Ethernet device in the other, you can then easily and instantly create a powerline network of up to 200Mbps, 2x of a traditional switch or router, with the driving capability of up to 300 meters, 3x of Ethernet cable. Plus the QoS feature prioritizes your bandwidth intensive applications for lag-free experience.
