super practical to connect PCs to the Internet via cable

impeccable, the 3 is the branch of a an outlet box to the internet cable is plugged in to this adapter box and you can plug into any other socket of the house (on the same circuits centralized on the same box breakers), the 2nd and 3rd adapters. Can you put a cable internet 2nd and 3rd adapters for PC and internet on a PC, wired mode, without doing anything, no configuration to do. very handy when the wifi does not pick a room to another because of thick old walls !! or if it does not work wifi. integrated power socket is very convenient as it catches are still available. I already had a lot of 2 and I bought the pack of 3 (5 of the same brand Netgear) and no worries, they are all compatible with each other!
