The T60H424 provides access to a wired LAN for wireless workstations.An integrated wireless and wired LAN is called an
Infrastructure configuration. A group of T60H424 PC users and an Access Point compose a Basic Service Set (BSS).Each T60H424 can
talk to any computer in the wired LAN infrastructure via the Access Point.
An Infrastructure configuration extends the accessibility of a T60H424 equipped PC to a wired LAN and doubles the effective

6 Ambit Microsystems Corporation
wireless transmission range for 2 T60H424 PCs. Since the Access Point is able to forward data within its BSS, the effective transmission
range in an infrastucture LAN is doubled.

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 T60H424 PCs and Access Point within one ESS must be
configured with the same ESSID and use the same radio channel.

3-3.2 ADAPTER CONFIGURATION – WINDOWS 98
After successful installation of the T60H424 and its driver, continue the installation process by
configuring the T60H424 adapter properties. To configure the T60H424 Adapter complete the
following steps :
1.From the Control Panel, double-click the “Network” icon.

11 Ambit Microsystems Corporation
2.Select "LAN-Express IEEE 802.11 PC Card Adapter" or "LAN-Express IEEE 802.11 MiniPCI Adapter" from the list and press the
“Properties” button.

12 Ambit Microsystems Corporation
3. From the “Properties” menu select the “Advanced” tab.

13 Ambit Microsystems Corporation
4. Select “Channel” from the list, and choose a “Value” from the drop down list. FCC
regulations require a “Value” between 1 and 11.
5. Select “Network Type”, and choose “Infrastructure” or “Ad-Hoc” as the “Value”.

14 Ambit Microsystems Corporation
Note: “Infrastructure” mode allows a wireless adapter to communicate with a wired network,
While “Ad-Hoc” mode allows wireless-to-wireless communication. Consult your System
Administrator for information about your network communication type. For more information
About Infrastructure and Ad-Hoc networks, see Chapter 2 of this manual
6. Select “Power Save Mode” and choose a “Value”.
NOTE: To allow uninterrupted data communication, choose “Disabled” as the “Value”.
Choosing “Enabled” allows your notebook to enter “sleep” mode, however, this will interrupt
data communication. Consult your System Administrator to find out the best setting for your
network type. For more information about Power Save Mode, see the chapter entitled “LAN-Express
Configuration Utility” in this manual.
8. Select “SSID”; enter a “Value” of “ANY”.

15 Ambit Microsystems Corporation
NOTE: The SSID can have any value, but should have the same value as the Access Point
(AP). In Ad-Hoc mode, all clients should share the same SSID
9. Select “Transmit Rate”, and choose a “Value”.

16 Ambit Microsystems Corporation
NOTE: Fixed 11 Mb/s is the preferred “Value” for environments where the client has line of
sight access and is a short distance away from the AP. Fully Auto is the recommended setting
for clients that are farther away from the AP and where there may be interference between the
client and the AP.
10. Select “Use Wep”, and choose a “Value”.

17 Ambit Microsystems Corporation
NOTE: Wired Equivalent Privacy (Wep) is an encryption scheme used to protect wireless data
communication. Selecting “Disabled” will prevent you from sharing data with other computers if
your network uses Wep. If your network is Wep enabled, you must choose “64bit” or ”128bit”.
Consult your System Administrator for more information about your network type. For more
information about Wep, see the chapter entitled “PRISM Configuration Utility” in this manual.
