comcast internet cable question
Posted by Ed Lim on February 23rd, 2004


We have 4 cable tv outlets all over the house and 1 data cable to the
home/office. We decided to install a netgear wifi system so I can
move around the house with my laptop. The kitchen is in the middle of
the house and installing the router there gives us the best signal
distribution throughout the house.

The problem is when I move the comcast cable modem from the home
office to the kitchen cable connection, I do not have access to the
net. Actually, putting the cable modem in any of the 4 tv outlets do
not give us any internet access, other than the one in the office.

But checking the incoming cable, all comcast did was put a splitter in
the basement and ran the cables on all directions.

Is there anything that would designate a cable or port as data and the
rest as tv only?

Any input would be great....

Comcast signal sucks. I had the same problem and a tech was here 4 times.
The 1st time, he installed a drop-amp and left. Still didn't work.
The 2nd time, he replaced every cable connector and left. Still didn't work.
The 3rd time, he replaced all but one splitter and left. Still didn't work.
Finally, the 4th tech replaced the main splitter and ran a separate line to
the modem. THAT worked.
Find the location where the cable comes into the house and put a quality
3-set coupler on it. Run one to the kitchen site and the other two to the
rest of the house. DON"T split it again at the kitchen! If need be, run 2
lines to the kitchen: One for the router and one for the TV.

installation question:

this is a 2 storey house with a basement. would it be best to install
the router at the basement, main floor or top floor?

first , on a normal house wifi, your best range is about 100 feet. Now this
may be more or less depending on the interference and the thickness of the
walls. Installing the router in the basement is a bad idea, the best
location for any antenna is high. That is why commercial antennas are all
mounted on towers.

You could put the router in the basement and run a external antenna outside,
cost is about 80 bucks for antenna.

Connecting your router to any cable outlet could be a problem if the wiring
is wrong. If there are to many splitters on the connection you will have
significant signal loss causing connection problems.
The way that I found that works the best for me is to run a straight cable
from initial splitter to the modem using rg6u triple shielded wire.
