This Ethernet coupler/extender helped me to give more slack on my Ethernet cable, being that the idiot who installed new carpets ran the cable underneath of the new carpet! Which wouldn't have been too bad as it would've been out of sight, rather than looking gaudy running along the edges of hallway and walls, but the dumb-*** kept like 10 extra ft of cable in the room where my Comcast Modem/Router is, and only like 2-3ft of extra cable in the room that I soley need it for! The extra cable actually comes out from the edge of the hallway carpet, at my bedroom doorway, which initially made the cable taunt when connected, and could only be in spot close enough for my ps4 to reach the Ethernet, and even then u could only move it approximately 6inches in any direction! This helped me to be able and buy another smaller cable to extend the connection and give my ps4 a little more freedom to move! I just wish I could've found a 1 to 2 adapter!
