As described in the description, this universal repeater installs in minutes and requires no installation or connecting Ethernet cables CD, a push of the button "Push 'N' Connect" and computers connect universal repeater and the deal goes without worries.
Configuring places: a Livebox 2, approx 10m with two bearing walls between the box and the computer a second to 1 with 1 basement concrete slab in addition, very weak signal and often random for the first and nothing for the second. With repeater not any worries connection.
Note I connected the mid remote repeater between BOX and ordis.
