Existing configuration: a Livebox, two PCs and a printer and one PC to the floor below. Objective; get rid of Wifi connections, as several serious studies show it to be "dangeriosité", especially a baby is nearby. So I looked for a flexible solution without drilling wall, cable break to solve my problem. After reading, I turned to Netgear has good press and to the housing 104 XE because it offers 4 by switch box (very interesting from a practical and financial). So I bought two boxes, not a pack of two (worth the equivalent of three boxes). Installation very easy and fast subject not to plug them into power strips for performance reasons. Short recommending for networks both personal and professional (TPE)
