Example: The network component and
host component of the device whose IP
address is 192.168.1.2 when the subnet
mask is 255.255.255.0

2: host component
TCP/IP (Transmission Control
Protocol/Internet Protocol)
A protocol which the personal computer
within the network uses for
communication. TCP/IP is used in
Internet and is used the most world wide.
This LAN card uses TCP/IP for
communication. In order to
communicate using TCP/IP, a device
requires the IP address which works as
ID number.
WEP (Wired Equivalent Privacy)
WEP encrypts data transmit through the
wireless LAN to prevent tapping of
information.
To activate WEP, characters to be used as
the key for encrypting the data being
transmit using the wireless LAN must be
specified. Input five alphanumeric
characters.
Wireless channel
In IEEE802.11b wireless LAN standard,
2.4 GHz band is divided into 14
channels. To prevent an RF interference,
separate channels can be specified for
different wireless networks which are
close to each other. This LAN card can
use channels 1 to 11. In infrastructure
mode, a channel specified by the access
point is used by all the devices within the
network. In ad hoc mode, the channel
must be specified by all the devices
within the network.
