1st analysis (on 20/11/13): I tried for 2 days full time and not associate with my pair of Freeplugs already in place. I wanted to connect my PC to the Internet and it does not work despite successive resets, associations on the same wall outlet etc ... Yet they are shown to be compatible with all the box ... So, I'm asking a return refund. Second analysis (on 11/23/13) and finally I managed to combine ... You should know that the, basic, 2 cpl can be associated together, but not with one or a pair of Freeplugs. That is, use the "SoftPlug" software on your PC (does not work on Mac) and connect one by one all your CPL (Freeplug and TP link) on your PC. Beforehand, select "add a NetPlug" for which you will learn the MAC address and the password of the PLC concerned. Then, "Enable NetPlug" to associate the NetPlug to NetPlugs (CPL) already present (associated) and recognized by the network. Then your Cpl dispatcher where you need. Finally, I keep and am very satisfied !!! I do not put "only" 3 stars because I have struggled to achieve the result and have found very little information on this subject on the internet.
