5. Modifying a Wireless Network
5.1 Infrastructure Mode and Ad Hoc Mode
You can set the Wireless Network Adapter to work in either Infrastructure mode or
Ad Hoc mode.
NOTE! Ad-hoc mode is available only for 802.11b/g. It is not available for 802.11a. This is
a client product and do not have radar detection function specified by FCC. The software will
not let you to use ad-hoc under 802.11a.
Infrastructure Mode
In infrastructure mode, devices communicate with each other by first going through an Access
Point (AP). Wireless devices can communicate with each other or can communicate with a
wired network. When one AP is connected to wired network and a set of wireless stations, it
is referred to as a BSS (Basic Service Set).
Ad Hoc Mode
Ad-hoc mode is also called “peer-to-peer mode” or “Independent Basic Service Set (IBSS)”.
In ad hoc mode, devices communicate directly with each other without using an Access Point
(AP).
NOTE! Ad-hoc mode is available only for 802.11b/g. It is not available for 802.11a. This is
a client product and do not have radar detection function specified by FCC. The software will
not let you to use ad-hoc under 802.11a.

5.2 Modifying a Wireless Network
1. Open “WLAN a+b+g USB2.0 Adapter Configuration” by double clicking the shortcut icon
on the desktop.
Note! If there’s no network name listed in the “Profile List”, click Refresh button
and double click a Network Name from Available Networks. The chosen Network
Name is listed in the Profile List.
2. From the Profile List, select one Profile and click Modify button .

16
3. Select Profile Editor tab and edit the settings. Click OK to save the modifications.
Configuration Name: This name identifies the configuration. This name should be
unique.
Network Name (SSID1) (SSID2) (SSID3): The name of the wireless network. This
name cannot be longer than 32 characters. If the field is set to be “ANY” or is left
blank, your computer will connect to an AP with the best signal strength.
Network Connection: Specifies the mode of the network. Two options are
“Infrastructure” and “Ad Hoc”.
Power Saving: Minimizes power consumption while maintaining
network connectivity and high data transfer performance. In Ad Hoc mode, Power
Savings function cannot be enabled. The power management options are:
• Off: PC Card is powered up at all times.
• Normal: PC Card sleeps less often and stays asleep for a shorter period.
• Maximum: PC Card sleeps more frequently and stays asleep as much as
possible.
Wireless Mode: Three options are “802.11b”, “802.11a”, “802.11g”, “Super A”,
“Super G” or “Auto”. “Auto” allows the use of either 802.11a, 802.11g or
802.11b mode.

17
NOTE! Ad-hoc mode is available only for 802.11b/g. It is not available for 802.11a.
This is a client product and do not have rador detection function specified by FCC.
The software will not let you to use ad-hoc under 802.11a.
Ad Hoc Net Start: Specifies a band to establish an Ad Hoc network if no matching
SSID is found. Options available are the following: 802.11b and 802.11g.
NOTE! Ad-hoc mode is available only for 802.11b/g. It is not available for 802.11a.
This is a client product and do not have radar detection function specified by FCC.

802.11b Range: Options are Normal Range and Extended Range. This
function can let user to determine the transfer range in 802.11b mode.
Extended Range can prolong the transfer range with a lower data transmitting rate.
Scan Mode: Options are Active Scan, Passive Scan and Auto. In Active Scan, the
driver sends out the probe request frames from each channel and collects the
response frames from the responding. In Passive Scan, the driver scan each
requested channel, listening the beacons on each channel.
Transmit Power: This setting allows you to change the output power of the PC
Card to increase or decrease the coverage area.
QoS: Disables or enables the PC Card to cooperate in a network using QoS
(Quality of Service).
2.4 GHz Preamble: Allows Ad-Hoc compatibility with other 2.4 GHz devices. Two
options are Short and Long and Long only. Use Long Only when configuring
the client for an 802.11b RoamAbout AP wireless network.
