My router is in the next room on the opposite side of my bedroom wall.
My goal is to have a ethernet jack on my side of the wall for my PC to connect to and an ethernet jack on the other side of the wall.
I’ve found there are inline coupler jacks (where I would have a short ethernet cable inside the wall connecting the two with RJ45 coupler jacks inside the wall) or is it better to use two keystone jacks connecting them by a short patch cable and puching the wires down?
Short patch cable and 2 RJ45 couplers will work fine and is much simpler if you don’t have the tools for punch downs.
I measured the depth of the wall which is 4" Is it a safe bet to get a 0.5’ patch cable to connect the two couplers? Or should I go with 1ft?
I love this argument. I prefer inline, because I’m faster at crimping and troubleshooting an rj45 than punch downs. As for technical accuracy some say punch down is better for POE, and if you need to get your drops certified but I don’t think in a residential setting it matters (runs less than 100ft)
