Cable Modem question
Posted by Jack Mello on April 14th, 2004


Can you have have more then one computer on a cable modem line? I have
one computer hooked up, working fine, how can I add another without
paying more? Do I just need to get a router?

That's the easiest way. I personally like Linksys; others prefer
Netgear.

Yup. Any router will do, Linksys, Netgear, Dlink, Zyxel, etc.

You have three basic options for sharing one TCP/IP address:

1) You can buy a router/firewall with a built in switch such as the Linksys
BEFSR41 Etherfast Cable/DSL Router...for around $70. This will connect all
your PC's together as well as connect to the internet and share the one
internet connection. This is a small device, quiet, cheap, and can be left
on all the time. Each PC is independent of each other so either can be on or
off without affecting the other. If you already have a hub or a switch, go
for the Linksys BEFSR11 model for about $50.

You can also get a router that has both wired switched ports and wireless
capabilities such as the Linksys BEFSW411 Wireless-B Broadband Router. You
will also need a wireless NIC / Adaptor for your PC/Laptop. This will free
you from being physically connected to the router via Ethernet cables.

2) Add a second Ethernet Card to the PC connected to the Cable Modem, and
run proxy software...i.e. MS-ICS, Sysgate, WinGate, WinRoute, AnalogX, and
some firewall software...i.e. ZoneAlarm or BlackICE. You can use a "cross
over cable" to connect two PC's together...but a hub or switch would be
better. A hub or a switch is a must for more than two PC's. This is option
is cheap and easy but requires that the main "router PC" be on all the time,
or at least on while you want internet access from the second PC.



3) If you are up for the challenge, you can setup a Linux system to share
your connection and provide proxy and firewall services. This requires a
third PC and some Linux expertise. You will still need a hub or a switch to
connect everything together.



I would check out the following links for more info on options, products and
reviews.

Limits on hooking up more then one computer directly to a cable modem
is controller by your cable modem's ISP
I've had 3 or 4 computers (with a hub) hooked up to my Surfboard (Comcast)
cable modem, each computer getting a DHCP IP from the ISP.

Or get a Router

I assume you have to pay (an extra $4.95) for each IP?

Nope

What is a HUB?

I know a Router, but not a HUB.
