VERY New to this. Need assistance with CAT 6 wiring

post #1 of 7
Thread Starter 
Forgive my ignorance but I am very new to home networking (just how ignorant I am sure will become evident smile.gif
I am sure that some of the words I use are incorrect, but humor me.

I have just recently purchased a home that (according to the sales information) is: 'Pre-wired for telephone with Category 6 wiring in kitchen, family room, den and all bedrooms'

Question 1:

Now I know that Cat6 wiring has a total of 8 wires inside of it. Problem is that all of my jacks are wired with 4 pins only (telephone).

Am I right in assuming that because the house is wired with Cat6 wiring, that it is as simple as changing/rewiring the standard telephone jack to a RJ45 jack? I would think that there are several wires sitting idle behind the telephone jack that are not being used.

My understanding is that Cat6 wiring for phone is overkill, so logic would tell me that they wired the home with the forethought that the owner could upgrade the telephone jacks to RJ45 jacks in the future.

Question 2:

Assuming that I could change these jacks into RJ45 jacks, how would I handle the connection to the incoming coax cable connection.(I plan on using Comcast high speed internet)

All of the Cat 6 wiring runs into a box on the outside of the house/side of the garage that is labeled 'telephone'. All of the Cat6 wires originate at this point.

Would I need to install an ethernet switch at this point?

Do switches have an input for coax cable or would the coax cable need to go directly into a modem which would then feed the switch?

I will probably end up getting a professional to help me out but I just want to see if I have the understanding of the basis for a home networking system.

I appreciate any help!

I would suggest contacting the contractor who built your house and ask him these questions. If they can't provide you with an answer, I would suggest contacting a contractor who specializes on doing this type of work. If you mess up one strand of the Cat6 cable, it will create some headaches.

With that said, it is possible to change it to RJ45, but then again what are you going to use for the telephone line? If I was you, I would just make your own Cat5e or Cat6 runs.

I just rewired my own house with cat6. Though cat 6 has 4 twisted pair wires only 2 wires are needed to run each phone line. If it was me id simply plug my phone in to the connector, if you get a dial tone then its good for either dsl or phone. Btw. Home depot sells a jack that accept both rj11 and rj45 connectors. Its an either or kind of thing.

As for #2. Cable uses rj6 for internet. At the point where the modem is you will have the rj6 connect at the back. Then an rj45 connector for internet. Connect this cable to a router and use the additional ports for wiring network access for the rest of the house.

The cat6 standard allows the contractor to run one high quality cable to deliver telephone and internet. If you plan on streaming HD video to any room in the house then cat6 is great for this as well. Gigabit speeds are cable with cat6.

I want to point out that many times electricians only run a single CAT5 or CAT6 wire to each room. There are four twisted pairs in the wire. They use two pairs for internet and the other two pairs for phone. This is done all the time and it works. Not the best arrangement, but it does work.

I recommend making two runs of CAT5 or CAT6 to each room if possible. Then you can use one wire for phone and the other wire for internet. There are many advantages to this arrangement including Gigabit speeds between different devices on your network. Otherwise, if you only use two of the four pairs for internet, you are limited to 10/100 speed. Don't worry this is enough bandwidth to stream video.

Many people use wireless phones and only need one phone connection in their house to the base station for the phone . The other wall plates can just be hooked up for internet. This will give you full bandwidth internet connections to the majority of the house. Anywhere in the house that you need a wired phone connection you will have to split the single CAT5 or CAT6 for phone and internet.

We wired 2 CAT6 wires into reach room with a TV and outside all into a closet in our 1930's house. Monoprice has an adapter that converts the 2 CAT 6 cables to HDMI. In case you end up running more wires.

I'm 99.99%sure you cannot split some of the cat6 wires off to run phone and the other wires to run internet. You need all 4 pairs of wires to complete the signal for internet. It doesn't work as 10/100 with 2 pairs and gigabit with 4 pairs.

Now what the home builders will do is use cat5e wire as a phone line and you can hook up 1 pair of wires for each line. So you you can have up to 4 lines with 1 cat5e wire.

But yes if you do use a home phone and internet, it's a good idea to have them run 2 cat6 lines to each room.
