Router education

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
    I want to provide Internet access to a 2nd home PC without having to
drag the modem and cable clear into the next room,(40ft.). I have been
told I can use a wireless router and it will just locate the signal
from the 1st PC and connect using that. I have no knowledge concerning
routers and have never used one. I use a SB5120 modem from Motorola
with Comcast cable.
    Can anyone help me with an adequate router which would let me access
the Internet with BOTH pc's at the same time? I don't imagine I need
'bells & whistle's' since I won't know what their for anyway. I do
have a pretty good firewall already. Many thanks for advice.

Thank you for providing the modem number of the modem :-)

   "You can use your high-speed, upgradeable cable modem to connect one or more
    computers in your home or business to the Internet. You can connect:

    Two computers; one to the USB port and one to the Ethernet port"

This is how you'd do it.

    cable wire ----- SB5120 ----- USB ------------------- to computer next to
the modem
                            ----- Ethernet cable -------- to computer 40 feet

 From the manual:

    "The USB connection requires special USB driver software that is supplied
     on the SURFboard Cable Modem CD-ROM."

That's how you get the computer which connects to the SB5120, to get
a working network.

You can get an Ethernet cable for the other computer for about $10.
(If you buy one locally, they'll charge a fortune for it. Locally,
  all I get for $10 is a 10 foot cable.)

The thing about using the equipment you've got, and not going wireless,
is not going through the pain of setting up the wireless.

I have one computer in another room, and run a long Ethernet wire to
connect it up. According to this, you can use an Ethernet cable with
RJ-45 connectors on the end, for a distance of 100 meters (300 feet).

One thing I've noticed, on the ends of my new cables, is the "release"
plastic thing is hard to work with your fingers. I took a hobby knife,
and cut away the "hood" over the release, so it would release
more easily. If you don't do that, and the computer is in an awkward
situation, you may have to pull it out from the wall to work on it.
You don't want to be tugging on the cable, if the release hasn't
released yet. Experiment, plugging your new cable, into something
where it's easy to see what you're doing. If the Ethernet connector
on the equipment is surrounded by a plastic lip, it can be damn hard
to get that cable out again. I one case, I had to position a piece of
metal, to press on the release while I worked on it. I couldn't get
my fingers near enough to work it.


If you have your heart set on using a router, they come in two forms.
You can get all-in-one boxes, with DOCSIS cable modem, wired and wireless
router, all in the same box. That means, fewer network boxes in your

Routers are also available separately.

The advantage of a separate router, is generally the documentation and
user interface (web browser) can be better. The company can't sell
their router, unless people like it. With the all-in-one boxes, generally
those are rented or shipped to customers by ISPs, and only the ISP has
to be impressed with the box for it to sell. The customer doesn't
get a say in it, in that case. I have a product of that type here,
and it kinda sucks. I put my own router after it, and ran it bridged,
so I could have a better interface for setting up the router.

So if you want to buy a router, go to the manufacturer web site and
download the router user manual. If it's hard to read, then you know
what you'll be facing when it shows up.

The USB interface on your Motorola modem probably won't be the best.
You may get annoyed enough with it, to go out and buy your router.
But for the $10 for a cable, it might be worthwhile to give it a
try first, and see if it's good enough. It's all a question of
who will sell you a cable for a reasonable price.

The least networking box I bought, it cost more for the cables,
than for the networking box! It's pathetic. Silicon is cheaper
than wires.

It says:

"The SURFboard cable modem supports several multiple user
configurations. Along with an optional hub or router, it can serve as an
Internet gateway for up to 32 computers.Not all service providers
support multiple user service. For information about multiple user
service, contact your cable service provider."

I'm just going to assume not many of them do because it wasn't an
advertised service. At one time, Telocity, before being bought out by
DriectTV and then crashed and burned, allowed you to plug in a computer
to their mdoem via USB and Eathernet at the same time but would charge
extra for this servcice.

    Thank you Sitre for the response. I suspect you are right about my
Internet provider charging extra for another computer using its
service. I will seldom use 2 pc's at the same time but it would be a
nice option when needed. Thank you again.

I am living in the Netherlands and we used to have an issue with
internet providers her too who did not like you using 2 or more
computers with their internet connection. They don't make an issue of
this any more here but they still do in the States? Then put a
*switch* between your router and and your pc's and your provider will
very probably never know that you're using more than one computer. :-)
He will only see *one* ip-address: that of the switch.
I think a wireless switch is not called 'switch' but don't remember
the English word for it.

    Thanks Massimo. Maybe someone will know what this 'switch' is called
in the U.S. I'm gonna need all the information I can get from this
newsgroup to tackle this project. I hope to have the time for it this
weekend. Thank you.

A switch is a switch, but there is no need for one as a
router has one. A router looks like one source to the modem.
Just get a wireless router and you'll be all set.

It was not very noticeable imo but Sitre's quote was about multiple
users.  I don't think that's the same as a second, or third, or fourth
computer for the same user, that is the same account.  At any rate, I
use Verizon and had no trouble having one computer on the second floor
and another the basement using the same account.  I can't use both
keyboards at the same time, but they are sometimes both on, both
dl'ing mail every 10 minutes.

Your first post referred to getting the signal from the first PC.  For
the record,  it gets the signal from the router just as the first pc

Usually the PC near the router is connected to the router by a cable
and the other ones connected by wifi, but except for iirc initial
setup, there is no need to have any computer connected with a cable.

AFA bells and whistles, they probably all have them.  You can just
ignore them for the most part.  There will be quick setup
instructions.   There is I hear reason to encrypt the wireless signal,
but I don't know much about that.    I can't park near my house, but I
walked my laptop up my brother's driveway and I coudln't get any
signal until I was only 20 or 30 feet from the router, counting the
space inside the house.

    Thank you Paul. As usual I am saving your detailed response in my
"Paul's advice" folder. I will search out a cd-rom disc for the modem
I'm using, (Comcast didn't leave one with me), and give it a whirl. I
think the Ethernet cable will work just fine for my application. I'll
keep my fingers crossed that I won't have any ip address issues with
Comcast. Thanks again.
