Many people criticize this model. The speed is there but the network is sensitive to cohabitation with other objects connected PLC in the house. At home, my radiators communicate CPL, as my Freebox (server and 2 players). Also, be aware that many devices parasitize the quality of communication: anything that contains a powerful motor (vacuum cleaner, washing machine), or a microwave because they do not have active filter. Of course, the power quality also make the difference in a ratio of one to ten. I found the solution against interference between technologies by enabling network encryption with a configuration key in the interface. Since then, more problems.
