I just got a cable
modem from my cable company. I hooked it up and it works fine but
it only works with one computer and I have four. I asked my cable company
if I could hook up multiple computers and they said it would cost me
an extra $20 per computer a month. Screw that, I want it for free.
Here's how to trick your ISP (internet service provider) into thinking
you are only using one computer.
NOTE:
This article was written way back in 2001. Since then, this "modem
sharing" procedure has become very common. In fact your router
may come with setup software that makes this tutorial obsolete. However,
many times this setup software is Windows only. Mac, Linux and Unix
users should read on. If you have any questions, check your router's
documentation before continuing.
STEP
ONE
1.
I assume you have a cable
modem that works, and have more than one computer. Now all
you need to do is get the gear to share that broadband connection.
For this example I will be using the Linksys®
Ether Fast Cable / DSL Router because it is reasonably priced
and has a built in Firewall to protect your home network. You
can plug a wiresless base station like an AirPort
Express with AirTunes into this router to upgrade it later
to a wireless network if needed.
However,
if you are planning on adding any wireless computers to your
network in the future, get the Linksys
WRT54G Wireless-G Router because it has both wired and
wireless options. Also it's only about $20 more than the
regular router. There a two types of wireless routers B and
G. The G routers are faster and compatible with slower wireless
cards.
2.
Plug your main computer into one of the router's regular
ports with a piece of that ethernet
cable you got in step one. NOTE:
This tutorial doesn't cover USB connections. Don't
plug it into the WAN or Uplink slot, just one of the normal
ports. Then open a web browser and type in this address
http://192.168.1.1
to open the router's configuration screen. In this example
I am using the router shown above. As soon as you hit the
router, you will be prompted for a username and password.
Leave the User ID blank and use "admin" as your
password. This is the default setting your router comes
with. If this doesn't work, check your routers documentation.
Are
you using DSL? Some DSL ISP's require you to choose PPPoe
to connect. (Look into this if you can.) Click the Setup
tab, on the bottom of the page is the Login settings. Check
"PPPoe" and fill in your username and password
that was provided by your DSL ISP. If this is not the case,
make sure "Disable" is checked off for the Login
setting.
*
If you normally go through a proxy or a corporate firewall, disable
it in your browser's preferences or call your IT department.
If you don't know what a proxy is, this note probably doesn't
concern you.
STEP
THREE
3.
Select on the Status tab. At the bottom of the page is
a button called "DHCP Clients Table", click on that.
This will bring up a pop-up window with a list of devises and
their addresses. Write down your computer's MAC Address.
These 12-digits get assigned to a piece of hardware for identification
and are unique on your network. What we are going to do is take
this same MAC address and give it to your router as well. This
will fool the cable company into thinking your router is a computer.
Your router comes with a specific MAC address which the cable
company knows to block. That's why we have to change it. Once
you change the MAC address, your router will then handle all your
Internet traffic, (uploads and downloads), from all your computers.
The router will also protect your network with its built-in firewall
from evil hackers.

STEP
FOUR
4.
Now select the Advanced tab on the far right. You will
now be able to access a new set of tabs. Click on MAC Addr.
Type in the MAC address you wrote down in step three. Then press
the "Apply" button. You've just given your router and
computer the same MAC Address. High-five the nearest person or
stand in front of a mirror and give yourself a thumbs-up.
STEP
FIVE
5.
Now make sure your router is plugged into the cable modem! Plug
one end of the ethernet cable into the WAN port on the
router and the other end of the ethernet cable into the cable
modem's ethernet port. Back to your browser. Click on the gray
Setup tab on the far right. This will bring you back to
the basic router functions. Now select the Status tab again.
Scroll down the page to the WAN settings. Right now your DNS should
be all zeros.
On the page
is a button called "DHCP Renew", press that. It will
reload and give you some DNS
numbers. Write these down.
STEP
SIX
6.
Here's the final step. You need to tell your computers to go through
the router with all their Internet traffic or TCP/IP requests.
Type in the DNS numbers you got from Step Five.
Macintosh
OS 9:
<- Click to Enlarge Photo
Open
up your TCP/IP Control Panel from the Apple Menu. Under
the Edit menu is your "User Mode" settings. Make
sure Advanced is selected. Now type in your DNS numbers
in the "Name Server Address" window. Then close
the window, save when it prompts you and open your browser
to test it.
Macintosh
OS X:
<- Click to Enlarge Photo
Open
you System Preferences Panel. You can find this app in your
Applications or Utilities folder. The Configure pull down
should reflect what type of network connection you plan
to use. In this screenshot example it says "Built-in
Ethernet." If you plan on using a wireless card, the
pull down should say "Airport." So pick the proper
connection and then type in your DNS numbers.
If
you want some suggestions for wireless cards for you Mac
OS X laptops, I suggest these: Wireless
G card or Wireless
B card.
Windows:
Select
proprieties of your Network Neighborhood by right clicking.
Select Protocols > TCP/IP then click on Proprieties.
Now select DNS. In the DNS Service Search Order box, type
in those DNS numbers you wrote down.
You
can also access the TCP/IP settings by selecting the Control
Panel from the START menu. Then Network. Now click on TCP/IP
for the network card or port you want to see.
If
you want to get wireless cards for your PC laptops, I suggest
the following: PC
Wireless card B or PC
Wireless card G (faster). They are both priced under
$50. Remember G
speed router and wireless cards are faster than B sped
hardware.
For
desktop PCs you can add a wireless USB adapter. This is
an easy solution and requires no difficult hardware installation.
USB
wireless adapter B or USB
wireless G. This also can be a great solution for some
laptop users. Most laptops only have one card slot. So if
you card slot is already in use with another card, for example
a FireWire card for your iPod, then using a USB wireless
adapter would allow you to use both at the same time.
TROUBLE
SHOOTING
If you
run into problems, double check the above directions and make
sure everything is plugged in securely and in the right place.
Also, some applications like America Online or your Internet Services
Providers setup software may have some conflicts with your routers
new settings. Make a back-up and properly delete or uninstall
these applications. And when all else fails, restart your computer.
Windows users
should install the router's drivers and test everything to make
sure all hardware and software are working together properly.
Also, Windows users may run into driver conflicts, so its a good
idea to make sure all your operating system and router software
is updated. Check the router's company's website for software
updates.
Macintosh
users have it much easier and are ready to go right out of the
box. No drivers or extra anything is required. Just plug and play.
If your
router has not supplied you with DNS numbers and you cannot
reset it by pressing the reset button in the back;
1. Connect all your computers and cable/DSL
modem to the router. Turn everything on and restart computer.
2. Return to MAC Address Clone page, type zeros in the address,
apply.
3. Type in MAC Address again, apply.
4. Now when you return to the Status tab your computer should
have DNS numbers (number of DNS numbers depends on number of
computers.).
5. When you open your TCP/IP the sever address should automatically
be changed to the DNS number (usually the first one on list
the router supplies you with.).
Also, cable
modems are tricky. If you are repeatedly plugging and unplugging
ethernet cables all over the place, the modem will get confused.
Try unplugging the power cable from the cable modem for 30 seconds.
Then plug it back in. The modem should go through its power up
cycle. When it's done, try pulling up a web page. If that doesn't
work try calling your cable company's tech support. But be careful,
your cable company may not allow you to have a router hooked up
to multiple computers.

"I must thank you for the information contained in this piece.
I had already gotten the router and the cable and was flummoxed
to discover that all the documentation was exclusively windows.
I cannot tell you of my gratitude upon discovering this site and
the pure gold contained within. Took a little twiddling (once
I realized I had to reconfigure TCP before I could even summon
up the router set-up screen it went a bunch quicker). ~ Many,
many thanks!" CarolS.
No
problem.

"Would that wireless networking hub replace the cable modem?
And...what companies make good cable modems?" Perry
No. your cable modem is your connection to
the internet. The wireless router allows multiple computers to share
the same modem's internet connection. Both my Apple Powerbook and
my girlfriend's iBook as well as my G4 are all using Airport wireless
cards and connect to the same wireless router. You plug the router
into your cable modem. Buy this:

"I have 2 computers. One iMac and one G4 Cube. But only one
or the other works when I try to get on the internet. It's always
the first computer I turn on for some reason. What did I do wrong?"
Bill H.
You plugged your cable modem into the Uplink
port and not the WAN. Read
Step 2 again and say "Doa!" like Homer Simpson. Then fix
your mistake. 05/13/04
"I LOVE YOU GUYS!!! I REALLY, REALLY LOVE YOU GUYS!!! I used
to have DSL hooked up to my router and had a nice network going
for me, but then I switched to a cable modem and my network fell
apart. I've been struggling for almost a year trying to figure out
how to use my router with the cable modem and bring up my home network
again...every attempt failed. The best part is that the cable company
isn't getting any extra money from me...they are already charging
me an arm and a leg for their services, at least now I feel compensated.
I love you guys and for the info you have posted on how to Hijack
the Connection: CABLE/DSL --- please tell the author, J. Love that
he is awesome. I LOVE HIM!! (J.Love deserves a raise!! a nice one!!
)
(as you can see I'm very happy!!) YAY! Thank You!! " Claudia
