Our experts have penned down the process elaborately but in simple steps for you.

    1. For 100 Mbps to 1 Gbps, you will need a Cat5 or Cat6 cable
    2. If the Internet speed is 10 to 40 Gbps, you will need a stronger cable. We recommend either Cat7 or Cat8.
  • Choose an interior wall to run the cable from the attic to the location you want to connect it in. Interior walls are not insulated and that makes the job easier. 
  • Use cable loops to staple the cable along the way so that it stays in place.
  • Make sure that there are no electric wires along the length of the cable. Otherwise, interference can disrupt the signal. 
  • Find the wall header by measuring the path of the cable and then heading to the attic and finding the top of the wall you should focus on. 
  • Now, drill a hole into the header. An electric drill will make the job easy for you.
  • Make sure you drill it straight down and only through a beam.
  • Now send your cable down through the drilled hole as far as possible.
    • Go to the room you want to set it up in, cut a small hole, and pull the cable out. To make sure you cut in the right place, cross an X here while taking measurements.
