For those which want to install
a network to share a connection Internet high flow but
which does not want to be encumbered wire, the only solution:
to install a Wi-Fi network. Why prefer Wi-Fi and not Bluetooth?
Wi-Fi compared to Bluetooth is of a quality ratio/better
and more powerful price. Moreover it is armed better against
the hacking thanks to its reinforced functions of safety.
The Wi-Fi term comes from
Wireless-Fidelity which is based on the model of Hi-fi
To install a Wi-Fi network, it is enough only to one router
without wire (provided best with a fire wall) and to an
adapter for each connected computer. Maintaining it is
a childish simplicity to install all this thanks to the
recognition of the Plug-and-Play peripherals....
For the choice of the material, I leave you free choose
what you want. Will know that charts NCV or charts networks
to be installed differ according to computers': chart
NCV for an office computer and chart PC for a portable.
With regard to the mode of installation, you can choose
two of them.
The first, best for a field domesticates, is the ad hoc
mode. It is simple to set up and connects a maximum of
three computers between them.
The second is the infrastructure mode who is opened much
more, the zone of cover is extended much and can ensure
hundred connections. This mode is used for companies,
Before the installation of
the network, note information of connection network already
established on the PC. Go in the Control panel and open
Connexions network. Make a right click on Connection to
the local area network and choose Propertys/Protocole
Internet (TCP/IP) /Propertys. Note the address IP, the
mask of sub-network and the footbridge by defect. Then
click on get an address IP automatically.
Note the name to user and the password necessary to connection
to your service provider.
Once the router configured according to the explanations
given by the guide of installation, it is necessary for
you to parameterize the PC connected to the modem to be
the administrator. Go in the menu start/Favorius Network/create
a domestic network. Specify which computer is connected
to Internet and name it Serveur for example. Then enter
the name of the working group recognized by all the customers
of your network, preserve the default settings proposed.
The security of the network:
- You should define a password for the router.
- Change the SSID (or the name of the network) into a
personal name without it not being easy to find by a pirate.
It is possible that the router allows to decontaminate
the diffusion of the SSID so that the network does not
appear in the list of possible connections of the vicinity.
- To filter the MAC addresses by the router, that makes
it possible to authorize only the access to the PC having
quite precise MAC addresses. These addresses are printed
on the Wi-Fi charts and each adapter NCV.
- If you can it, to activate encoding WPA, if not activate
encoding WEP. Best is to combine both.
- Decontaminate the network and connection wireless telegraphy
if you do not hope to use the network for a certain time.
- Be discrete by relationship with your confidential data
and avoid multiplying the shared repertories.
- Think of updating via Windows UpDate all the operating
systems so that they are quite stable and stage of the
faults of safety. Update the anti-virus ones and ensure
that all the stations have a fire wall well.
Safety question, from many
networks are not protected. It is not rare that we collects
in certain buildings of the nonprotected networks wifi
what allows of surfer on Internet the expenses of the
neighbors. Indeed, much d’ users cannot protect
their network or forget to do it then qu’ it is
enough to some adjustments. It is also possible to pirate
For the security of the WiFI networks a new standard will
be born soon : the standard 802.11i; It will offer a better
safety of connections without wire. That should in particular
reassure the companies.
It may be that you have interferences. That is with the
equipment using the band of the 2.4 GHz., for example
certain materials of radiophonic diffusion or certain
medical equipment. It may be also that if your wife makes
heat water in the microwave, that disturbs the network.
They emit radiations in the band of the 2.4 GHz, and are
thus a potential source of interferences. Thus distant
from the network...
For speed, of new equipment called Wifi SuperG allow today
to reach flows of 108 dry Mbit.
About the range of connection, there are obstacles between
your portable and the relay : the Netgear manufacturer
has just developed a system baptized smart MIMO which
makes it possible to multiply until by 10 the range of
the Wifi waves. It is a router who integrates one loads
of small antennas to cover what the dead zones are called.
