I bought these CPL wifi adapters for christmas my in-laws. I therefore responsible for the install their ... VERY VERY easy to install (placed after a Livebox). Not even need to reconfigure the computer with a new key wifi !!! (Simpler than those of another brand that I have at home where the wifi key is different depending on whether it is connected to the PLC or livebox itself !!!). Despite what is stated in the instructions, they work even on a power strip. Excellent signal.
