Hello

I am in the process of an addition to my house and had a couple of
questions if you don't mind. When wiring the extension for comcast
cable TV, cable high speed internet access, which wires do I use??

At home depot one guy told me to buy the 18/1, another said the CAT 5,
another said BOTH!!!

I was hoping someone could shed some light on this for me.

Thanks!

Cabling should be "home-run". That is, run a separate cable from each
outlet to a central wiring point. That gives you maximujm flexibility
for a very small extra cost in cable materials.

For Ethernet,, run CAT5e to the central point. For RF cabling, use a
quality RG6 with crimped-on connectors.

Same thing applies to POTS phone wiring.

It's not all that difficult.

He might need more details. The cable TV should obviously be an RG6 line.
The Internet Access should (if done right) be CAT5e, as you suggested. But,
that would assume that there is a broadband sharing router attached to a
cable modem, and that both exist before the extension is built. If not,
then the OP needs a router, also. He might also need a different cable
modem, if his current cable modem is NOT ethernet type. (so it will work
with the router)

Me, I'd probably run two lines of RG6 AND two lines of CAT5e. While the
walls are still open, this will be easy and cheap. Plan for the future.
Never know when those extra lines might come in handy. -Dave

"BOTH" is closer to reality.

You will need coax cable (someone else said RG6; I'm not sure of the
specification) to go to the TV and cable modem. You may want to run 2 separate
cables either from the point where the cable first enters the house or from an
accessible location at the addition; the cable modem needs a separate cable with
a filter.

Cat 5 Ethernet cable is used between the cable modem and the computer; or
between the cable modem and router, and between the router and individual
computers in the case of a Local Area Network (LAN) with several computers.
Wherever you set up your cable modem is where you want to set up your router,
which will be the central access point for your LAN. From there you can run Cat
5 cable to other rooms. A single cable to each room should suffice; you can add
an Ethernet switch in any room where you want to set up multiple computers.

For cable tv runs, get good quality quad shield RG6 and terminate with
high quality connectors (ie not the twist on crap). I use
Thomas&Betts snap-and-seal compression connectors. Belden and
Commscope are good cable brands.

For network, get a high quality Cat5e or better. Again, I recommend
Belden Datatwist 350.

I would also run coax for satellite dish, unless you just know you
will never use it. Run two lines+phone to major rooms (living room,
home theater, etc) to handle dual tuner receivers like the Directivo
units from Directv. Run a single line+phone to other less important
rooms to save cable cost if you want. Make sure the cable you buy for
satellite runs has been sweep tested to at least 2Ghz. Regular
shielding is OK here.

Hook up the cable modem in the central wiring location. Hook it to a
router with switch and use the ports for computers on that floor (and
1st floor if this is in a basement). Use the uplink port to go to
another switch for 2nd floor.

Most people want to wire all rooms to the central location, and you
can do that if you are in the framing stage. In my case, though, we
bought our house already finished so I will use the above method to
wire internet. I just have to run one cable from basement to attic
this way.

Plus, if all your bedrooms are on the same floor, you can put the
switch in your bedroom closet and pull the plug to the kids computer
if they are mouthing off.

Yes they do.

It is cheaper and easier and more convenient to use a wireless network.
You can then place computers anywhere you want, take your laptop out to
the yard, etc. There really is no unauthorized access problem any more,
most modern 802.11 AP/routers can be told to accept connections from
specific adapters only (you enter their hardware IDs).

And Windows is the most secure OS ever! Sigh. You are in for a BIG
surprise some day.

Heh, you need to check your math, Chuckles. Cat 5e wiring costs almost
nothing nowadays...

Hate to tell you, but current wireless security is embarrassingly easy to
break. Hacking MAC access lists (what you're referring to) is trivial -
sniff out the address of any accepted adapter (found in the header of
every packet), and set your adapter to match. There are automated packages
out there to do it (and break WEP too, of course).

Just take your laptop and wireless card to any tech conference, and people
will gladly hack into it for you....

Now, obviously, true wireless security is possible; it simply hasn't made
a lot of market penetration yet.

Well, it's "trivial" only if you can sniff enough data. 128bit WEP takes
over
100MB of concurrent data in order to get the key. Depending on the WAP
being
used, the MAC list is most likely encrypted as well when WEP is on.

IF you can get the right amount of data, then yea it's easy to hack.

You'll notice I was careful in what I called "trivial" - MAC lists alone.

However, speaking of WEP, there are other hacks which can be considerably
faster than the IV-based one you're presumably thinking of. (Which,
incidentally, is more or less independent of key length - 10,000 bit WEP
would be just as vulnerable.) A cute one is that some access points can
be tricked into decrypting packets for you! See

http://www.nwfusion.com/research/200...wepprimer.html

for a few notes on the subject.

Of course, security concerns are all relative. I'm actually typing this on
a laptop with a wireless interface where I don't even use WEP. Why? Well,
for various reasons, all its traffic is tunneled through ssh anyway. So,
absent the next ssh bug (which no doubt will appear tomorrow now that I've
typed this), and disregarding things like denial of service attacks, it's
not an extraordinarily vulnerable setup.
