So I am moving into a new house and want to run cat6 to a couple of the room. I can run the cabling in the walls alongside the coax to the plates. So I started looking at monoprice to see what I should use for my jacks. Obviously for the punch downs i would need a punch down tool vs. the inline coupler i just plug in a cable. Would i notice significant speed decreases? Are there obvious technical differences i am missing or is it all preference? The longest the length of cables might be is 50ft into the coupler and a 15 foot out of the coupler. All the signals would originate from a gigabit switch in my office.
