Home and Small Office NetworkingRon Mettler, CUGGNovember 2006 |
Home and Office networking can be expanded to include other types of equipment such as “Wireless” networking equipped computers, remote wireless still and video cameras, media control centers which interfaces your sound and video equipment with your network either through wireless or wired connections.
To assist those that are interested in the installation of a network system either at home or in a small office environment, the following may help in getting started and hopefully will generate questions for the November 11 meeting.
Planning your network
- Plan your network layout. Define
where you would like to
have various computers setup. Determine a good location for your
broadband
modem and router (see below for a description of what function the
router and
modem serves). Do you need or do you desire to use a wireless
connection for a
laptop or notebook computer? Perhaps the inability to run wiring
between the
router and a computer elsewhere in the home or office makes a wireless
connection the best alternative.
- Once you have determined where your
computers will be,
decide where your printers will be located. If you wish to share a
printer, you
can accomplish this two ways. A printer may connect to one computer and
be
setup to share over the network by other users on other computers on
the
network. This type of setup requires the computer that connects
directly to the
printer to be running in order for other computers to use the printer.
You may
even set the remote shared printer as a default printer for more than
one user.
- Printers can also be shared by
connecting them directly
to the router either through a wired Ethernet connection or a wireless
Ethernet
connection. Some low cost printers include built-in wired and/or
wireless
Ethernet interfaces. One of our club members just recently purchased an
HP
all-in-one Series 6100 printer/copier/scanner. The device included a
wireless
Ethernet interface that he connected to the router (without wires).
This
enabled him to print or scan from either of two computers in his house.
This
type of connection does not require that a computer be directly
connected to
the printer and be running as in 2 above.
- A printer without an Ethernet interface can be utilized as a network printer by adding a printer server. Simple wireless print servers may be the desired option to consider. Again, such a printer setup does not require that a computer be connected to it. With the printer on, any computer can be on and setup to print to that printer.
Basic equipment
needed.
- A broadband modem to connect to your
incoming broadband
service provider is required. A modem is a small piece of equipment
that can be
purchased or rented from most broadband service providers such as
Comcast or
Qwest or it can be purchased from places like Office Depot, Circuit
City
or Best Buy. Be sure to look
at the service plan for your broadband provider to determine whether
you should
rent or purchase. The modem can then be connected to one computer or it
can be
connected to a router to enable home or office networking.
- A router enables the modem connection to be distributed
and shared by other computers and equipment such as printers as
outlined in
A.3. and A.4. above. A router includes built-in firmware that is used
in
setting up various parameters for the network. Firmware is a program
stored in
the memory of the router that is accessed with a browser such as
Firefox or
Internet Explorer. Setting up a router for a home or small office
involves a
number of steps that will be covered in detail during the meeting
discussion.
Some of basics are covered below to whet the appetite.
- Network cards are required for each computer that will be on the network. Most computers purchased in recent years include at least a wired Ethernet card. If running a network cable between the router and each computer is not a problem, then the wired connection is the recommended method. A wired Ethernet connection provides more reliability and system security than a wireless connection does. If a wireless connection is the preferred option, than the remote computers have to be equipped with an internal wireless card or an external USB type of device. Most mid-range and up laptops come equipped with a built-in wireless system.
Setting up the basic
system
Usually the broadband service provider will have installed the modem or supplied the modem with a setup disk. The modem should then be connected to a router with a short Ethernet cable. Ethernet cables can be purchased in various lengths with connectors installed. The cable is also referred to as Cat 5 or Cat 5E cable. Most broadband modems will include a short cable for the modem to router connection and most routers will include a short cable for the router to the first computer.
The setup your router, the following is a brief outline of the procedure:
- Access the router using IE or
Firefox. Check your manual
to see what address to type use. Typically, D-link routers use
192.168.0.1 and
Linksys routers use 192.168.1.1. Just type the address in the address
line
where you normally would use to go to a site such as yahoo.com. You
will then
see a popup window asking for a user name and password. Typically you
will type
in Admin and then skip the password to go to the next step.
- The various screens that need to be
looked at and filled
in will vary with each kind of router. The mandatory fields to fill in
are as
follows:
- The password to access the router
should be changed from
a blank to a suitable password - cugger65t6, manlyguy86, etc. Remember
the
password for accessing the router at a later time.
- Set the SSID (your wireless network name) to something
other than default, Linksys, or D-Link. You should not want your
neighbors to
associate the SSID name with your system. Then find where you can
“disable
broadcasting of the SSID”. This sets the system to require a
wireless computer
to have to already be looking for your SSID instead of you announcing
to the
neighbors that you are there.
- Set a wireless encryption pass
phrase using WPA/PSA/TKIP
encryption. You will find that option somewhere in one of the setup
screens.
Use a password such as littlekid09 (alpha and numbers). This sets the
wireless
router to only accept wireless connections from computers that already
have the
pass phrase input and the SSID name input.
- Usually the default settings for all other screens will be set to what is needed for the router to operate properly.
If you are totally or partially confused at this point in time, ask your questions at the next meeting. Fortunately, all new modems manufactured from now on will have new firmware that steps you through the basics and prompts you to use at least those security measures mentioned above. We will demonstrate the details of setting up a couple of different routers. We will also touch on TCP/IP settings and how they are used.
