Device Configuration
Configuration of the Wireless Network Adapter can be done
through the NIC Configuration utility found in the Windows Control
Panel. The device can be set to work in one of two modes:
infrastructure mode or ad hoc mode.
In infrastructure mode, the Wireless Network adapter participates
in a basic service set (BSS) as a station, and communicate with
other stations through an AP.
In ad hoc mode, a Wireless Network Adapter work within an
independent basic service set (IBSS). All stations communicate
directly with other station without an AP.
To configure the Wireless Network Adapter:
1.
In the Device Manager, right-click “Wireless Network Adapter,”
and click Properties to access the properties of the adapter.
2.
Configuration additions, modifications, and deletions are made
under the “Setting” tab of the “Wireless Network Adapter”
3.
Select one of the configurations under the configuration list,
and click Modify to show the “Network Configuration Settings”
screen. This property sheet has two pages: General and
Security. Table 2-1 provide descriptions for the fields on the
General page.

Field Name
Description
Enable Security
Completely enables or disables the IEEE 802.11 wired
equivalent privacy (WEP)security feature.
Default Encryption Key
Defines the type of encryption key to use (either Unique Key
or Shared Key ).This field allows you to elect only a key
(Unique, First, Second, Third, or Fourth) whose
corresponding field has been completed.
Unique Key
Defines the unique encryption key for security for the
current network configuration. In ad hoc mode, this
encryption key type is not used. To enable security using a
Unique Key, This field must be populated.
Shared Keys
These fields define a set of shared encryption keys. To
enable security using Shared Key ,at least one Shared Key
field must be populated.
Key Length
Defines the length for each encryption key. A the Key
Length is changed, the number of available characters in
the field is changed automatically. If after a key is entered
the length is adjusted to a smaller number, the key is
automatically truncated to fit. If the length is increased
11
Wireless Broadband Router User Manual
again, the field is not automatically updated to it previous
value.
Selecting Encryption Types
We support two encryption type ;Wired Equivalent Privacy
(WEP)and Advanced Encryption Security (AES).While WEP is
universally supported and commonly used, AES provide a much
higher level of security, that is, frames encrypted with AES are
more difficult to decipher without knowing the key. To use AES,
you must specify a unique key (refer to Table 2-2).
NOTE: AES is not supported in ad hoc mode, since ad hoc mode
does not support unique keys.
Select the encryption type automatically (auto) or manually at both
the STA and AP. By specifying auto, the STA and AP will negotiate
and attempt to use AES before exchanging data packets. If AES is
not supported by the STA or AP,WEP is used. Manual selection
allows you to specify the encryption type. By default, the STA is set
to auto and will first attempt to use AES, and will only use WEP if
the AP supports, or is configured for WEP only.
Use the Advanced tab on the “Wireless Network Adapter” dialog to
change the encryption type.
Table 2-3 provides descriptions for the fields on the Network
Configuration Setting, Advanced tab dialog.

Description
Configuration Name
This field identifies the configuration. This name must
be unique. Configuration names are case insensitive.
Network Name (SSID)
This is the name of the IEEE 802.11a wireless

Locally Administered Address
(LAA)
This field defines the locally administered MAC
address. To enter a value in the address field, the
check box needs to be selected.
Usually infrastructure m ode is used in an enterprise environment
where APs are installed and maintained by corporate IT staff. Much
of the data in the enterprise network is confidential. It is important
to configure security to make sure only stations with appropriate
keys can receive sensitive data. The Wireless Network Adapter
and NDIS driver support key lengths of 40 bits,104 bits, and 128
bits. Typically, the appropriate encryption and decryption keys are
supplied by the corporate IT staff.
Ad Hoc Mode
An ad hoc network usually is a short-lived network with a small
number of stations. The network is usually created for a special
purpose such as exchanging data between friend ,or between
customer and client. Because the duration of the ad hoc network
tends to be limited, Power Saving and Security features are not
typically a requirement. For ad hoc network activity, the Power
Saving and Security features can be disabled. Currently, shared
key security is supported in ad hoc mode. Future software
implementation will provide unique key support.
14
Error! Style not defined.. Error! Style not defined.
In ad hoc mode, a station scans the air for an existing BSS. If no
BSS is found, the station establishes a BSS for other stations to
join. When other stations scan the air and find an established BSS
in place, they join that BSS to form an ad hoc network. If a specific
set of stations requires ad hoc network connectivity, it is
recommended to have one station establish a BSS first before
configuring the remaining stations. This prevent the scenario of
several stations trying to form a BSS at the same time, which can
result in multiple singular BSSs being established, rather than a
single BSS with multiple stations.
Table 2-5 summarize the field description for the General dialog in
ad hoc mode.
TCP/IP Setup
After configuring the Wireless Network Adapter through the
Network Control Panel, the TCP/IP address for the network device
must be configured.

Windows XP Wireless Network Configuration
Aside from using the Network Control Panel (NCP)to configure the
Wireless Network Adapter, Windows XP provides
zero-configuration functionality that automatically tries to connect
the STA to available wireless networks in the following order:
•
•
•
Infrastructure mode with valid WEP key
Infrastructure mode with unauthenticated acce for tation
without WEP keys
Ad hoc mode
To configure wireless network setting through the Windows XP
user interface:
1.
Open Network Connections from Control Panel.
2.
Right-click the Local Area Network Connection icon (pertinent
to Wireless Network Adapter).
3.
Click Enable to enable the device first, and then click
Properties.
4.
On the Wireless Networks tab, select the “Use Windows to
configure my wireless network settings” check box to enable
automatic wireless network configuration.

enabled)” check box is elected by default in Wireless Network
Properties.
3.
Select “The key is provided for me automatically” check box if
the WEP key is automatically provided for you. The driver will
then use the Default Encryption key from the current NCP
configuration profile irrespective of the network name.
You may choose to enter the WEP key by clearing this check
box and manually entering the network key and key length.
NOTE: The key format must be hexadecimal digits and the
key length is limited to 104-bit in Window XP, as opposed to
128-bit key supported by NDIS driver in the NCP configuration
interface. If the network that you are connecting to requires
128-bit WEP key, then it is recommended that you disable
Windows XP automatic wireless network configuration and use
NCP configuration instead.
Ad Hoc Mode
To connect to an existing computer-to-computer (ad hoc)network:
1.
Click the ad hoc network name under “Available networks” in

NCP configuration profile irrespective of the network name.
You may choose to enter the shared key by clearing this check
box and enter the key and key length manually.
NOTE: The key format must be hexadecimal digits and the key
length is limited to 104-bit in Windows XP as opposed to
128-bit key supported by NDIS driver in the NCP configuration
interface. If the network that you are connecting to require
128-bit WEP key then it is recommended that you disable
Windows XP automatic wireless network configuration and use
NCP configuration instead.
4.
If you want to connect to an ad hoc network, but both ad hoc
and infrastructure networks are within range of your computer,
then click Advanced in the Wireless Network tab and then
select “Computer-to-computer (ad hoc)networks only” .Note
that if you want the station to start it own ad hoc network, the
