TP-Link TL-PA211 AV200 Powerline Adapter Starter Kit (up to 200Mbps data transfer rate, 300 m maximum range, 2 Adapter-Pack) (Accessories)
Super functioning, even in our old (ie complex) mains we had no problems. Of course, the data rate depends quite strongly on the power grid, the "up to" indications are therefore, as the DSL contract, rather than a policy of real value reached.
