An Ad-Hoc wireless LAN is a group of computers, each equipped with one GL242201-0T,
connected as an independent wireless LAN. Computers in a specific Ad-Hoc wireless LAN must be
configured to share the same radio channel.
Ad-Hoc wireless LAN configurations are Access Point appropriatefor branch level departments or
SOHO operations

Fig. 2 -Infrastructure Wireless LAN Configuration
The GL242201-0T provides access to a wired LAN for wireless workstations. An integrated wireless
and wired LAN is called an Infrastructure configuration. A group of GL242201-0TPC users and an
Access Point compose a Basic Service Set (BSS). Each GL242201-0TPC in a BSS can talk to any
computer in the wired LAN infrastructure via the Access Point.
An Infrastructure configuration extends the accessibility of a GL242201-0Tequipped PC to a wired
LAN, and doubles the effective wireless transmission range for 2 GL242201-0TPCs. Since the
Access Point is able to forward data within its BSS, the effective transmission range in an
infrastructure LAN is doubled.

Access Point
Fig. 3 -The effective Transmission Range
The use of a unique ID in a BSS is essential. All GL242201-0Tequipped PCs configuredwithout
roaming options in an independent BSS must be configured with a BSS ID corresponding to the
ACCESS POINTused in the BSS. Check your ACCESSPOINTfor its BSS ID or use the Access
Point Browser Utility program to determine the BSS ID.
The Infrastructure Wireless LAN configuration is Access Point appropriatefor enterprise-scale
wireless access to a central database, or as a wireless Access Point applicationfor mobile users.
A point-to-point LAN configuration is possible when two access points are linked with an optional
directional antenna (the directional antenna is an optional accessory, please contact your dealer for

8
information). The optional directional antenna makes LAN-Interconnection to a wireless backbone
between buildings possible.
2-2ROAMING
Infrastructure mode also supports roaming capabilities for mobile users. More than one BSS can be
configured as an Extended Service Set (ESS). The continuous network allows users to roam freely
within an ESS. All GL242201-0T PCs and AccessPointswithinone ESS must be configuredwith
the same ESS ID and use the same radio channel.

3-3GL242201-0TDRIVER INSTALLATION -WINDOWS®95/98
Note: Before proceeding, have the Windows
®98 CD ready, as it will be required during the
software installation process.
1.Insertthe GL242201-0T into a standard TypeII or Type III slot, as described in the
preceding section.
2. Windows
®98will automatically detect the GL242201-0Tand prompt you to install the
necessary driver. Click “Next” to begin the installation.
3. Check “Search for the best driver…“and click “Next”.
4. Check “CD-ROM Driver” and click “Browse”. Double-click the “D:\Drivers\DU220108\TiCD”
folder icon from the list. Windows
® will automatically enter the path click “Next”. (where "D"
represents a CD-ROM)
5.Windows®will then acknowledge that it has found the Access Point appropriate driver, click
“Next”

11
Windows®will now install the driver
As the driver files are being copied to the AccessPoint appropriate location, you will be
prompted to insert the Windows®98 CD.
6. Insert the Windows
®98 CD. Select “D:\win98” from the drop down list (where “D” represents
the CD-ROM drive), click “OK”.
NOTE: You must insert the Windows 98®CD as the driver installation requires special files that
will not be available even if you have stored a copy of Windows® 98 on your hard drive.
7. After Windows®has finished installing the Access Point appropriatefiles click “Finish”
8. You will be prompted to restart your computer and click "Yes" to complete the installation.
9. After successful installation of theGL242201-0Tand its driver, continue the installation
process by configuring the GL242201-0TPC Card properties. From the Control Panel, double-
click the “Network” icon.

12
10. Select"TI ACX100 WLANAdapter" from the list and press the “Properties” button.
11. From the “Properties” menu, please select the “Advanced” tab.
12. From the menu, please select “Advanced” tab. First, Select “ AuthenticationMode”and set
up either “AutoSwitch”, “Open Authentication”or “SharedAuthentication”.
Authentication Type Indicati on of an authentication algorithm which can be supported by this
node:
Open System : Open System authentication is the simplest of the available authentication
algorithms. Essentially it is a null authentication algorithm. Any station that requests
authentication with this algorithm may become authenticated if dot11AuthenticationType at
the recipient station is set to Open System authentication.
Shared Key : Shared Key authentication supports authentication of STAs as either a
member of those who know a shared secret key or a member of those who do not.
AutoSwitchauthentication is the default authentication algorithm.
5. Select “Desired BSS Type” and set up thevalue:“Ad-hoc”,“Any ”or Infrastructure”.
An Ad-Hoc wireless LAN is a group of computers each with LAN adapters, connected as an
independent wireless LAN. An integrated wireless and wired LAN is called an Infrastructure
configuration.

13
6. Select “Channel” from the list, and choose a “Value” from the drop down list. FCC
regulations require a “Value” between 1 and 11.
7. Select “Desired SSID”and create the network name that matches the existing one or starting a
new one. The SSID can have any value, but should have the same value as the Access Point. In
Ad-Hoc mode, all clients should share the sameSSID.
SSID In infrastructure association, the stations will link to the AP with the same ESSID as they
have.
8. Select “Desired Tx Rate” and set up adefault value: The selections are “Auto”,“2Mbps”,
“5.5Mbps”, “11Mbps”or “22 Mbps”. The default is set to “Auto”so the device will perform auto fall
back to justify the actual through put of the network.

14
21. “Driver Description”indicates the name of the driver.
21. “Firmware File”provides the file name for the firmware.
21. Select “Fragmentation Threshold” and set up a default value: 2432. The value indicates
how much of the network resources devoted to recovering packet errors. The value
should remain at its default setting of 2432 bytes. If you have decreased this value and
experience high packet error rates, you can increase it again, but will likely decrease
overall network performance.

15
21. You may enter “Network Address”if you would like to specify the address. By default, it is
setto “Not Present”.
21. Select “Power Mode” to indicate if you would like to select “Continuous Access Mode”to
continue to have the device on without any power saving. To select “Fast Power Save”so
the device will remain the speed of the network while perform the power saving.
“Maximum Power Save”allowsthe device in stand by mode and wakes whenever there’s
a signal being detected.
21. Click on “Privacy Filter” to select ifyou would like to “AcceptAllPackets”which means
the device will accept any data that is coming from the network. In “Filtering Mode”means
the device will filter out any unnecessary packets from the network.

16
15. RTS Threshold: The value should remain on its default setting 2432 bytes. If you encounter
any date flow, only minor modifications are recommended.
16. “Rx Descriptors”means the receiving butter for your networks throughput. The greater
value will cause data loss where the less value will decrease the networks performance.
The default is set to 32.
17. “Short Preamble”means there is the “Off” or “On” selection to ensure that systems
receiving the information correctly interpret when the data transmission starts. To select
“On” Preamble may be used to minimize overhead and “Off” to maximize the network
data throughput. The default value will be set for “Off”.

17
18. “Tx Descriptors”means the transmitting butter for the network’s throughput. The greater
value will cause data loss where the less value will decrease the networks performance.
The default is set to 32.
19. “WEP Option”means this will display the status of encryption protocol. It can be “Off”, if
the WEP encryption protocol is not enabled. When it is necessary to use, it will be set to
“On”. Wired Equivalent Privacy (WEP) is an encryption scheme used to protect wireless
data communication. To enable the icon will prevent other stations without the same WEP
key from linking with the AP.
