Installation made to use a new box, an HD TV decoder, a PC, the rest: printer, laptop, smartphone are WiFi. Simple installation of the CPL, but the update of each adapter firmware is recommended and requires time, because few ergonomic and confused. These adapters replace my old Bewan Powerline E200, I do not see speed improvements, on the contrary, many cuts and loss of connection with the box, forced to reboot the box regularly, annoying ...!. Too bad because handy with 2 RJ45 port and PC filtered facial.
