To Build a network at home or office with minimum effort & cost, the Tenda 200 Mbps Powerline Adapter P200 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 in the office has a mains supply, which can be used to extend network connections from your broadband router. Simply plug one P200 adapter that links to a broadband modem/router into the mains socket in one room, & plug another P200 adapter linking to a PC or any Ethernet device in the other, you can then easily & instantly create a powerline network of up to 200 Mbps, 2 times that of a traditional switch or router, with a distance capability of up to 300 metres, 3 times that of Ethernet cable. Plus the Qo S feature prioritizes your bandwidth intensive applications for lag-free experience
