First of all, it's not a pack of 2 CPL Wifi .... There is only one (the other is based only). This is a false grip ... Beware if you hope to have 2 extensions Wifi .... The goal for me was to have 2 boxes wifi to connect to my existing PLC network ... And there's a hassle .... and the purchase is too expensive for one box WIFI! The configuration is laborious and after 3 hours, it still does not work properly It is particularly difficult to put a protection code to prevent an unknown WiFi connects to the network The manual does not match the software available now (and no help is provided) So avoid buying
