Figure 5 WaveLAN 

parameters 

The Network Identification Designator (NWID) is a unique code, that 

logically connects stations in a single WaveLAN network group (like cabling 

physically connects wired stations in a cabled network). 

Valid values are any four digit hexadecimal value in the range 0100 H through 

FFFF H. 

All workgroup stations in the coverage area must use the same NWID. For 

network environments that include WavePOINT access points, you are 

advised to enter the NWID used by the nearest WavePOINT (Consult your 

network supervisor for the correct NWID value). 

This parameter is optional if Roaming is enabled (next). 

If the network environment includes WavePOINT access points, you can use 

this parameter to enable Roaming. Roaming allows your station to connect 

automatically to the WaveLAN network, regardless of its physical location in 

the wireless coverage area. The station will listen for Beacon messages 

transmitted by WavePOINT access points to automatically retrieve the NWID 

code of a wireless workgroup. 

If Roaming Enable is set to “on”, you must specify the Domain ID and 

(optionally) a Beacon Key. 

If your wireless network environment does not include WavePOINT access 

points, set “Roaming Enable” to “OFF”. 

The Domain ID is a unique code, that connects multiple WaveLAN network 

groups (each having a unique NWID) into one wireless network environment, 

the Domain. Valid values are any four digit hexadecimal value in the range 

0001 H through FFFF H. 

(Optional) The Beacon key encodes the NWID information that is transmitted 

by the WavePOINT. All WavePOINT access points and stations in the

User's Guide that came with your WaveLAN/PCMCIA Card 5). 

(Optional) This option can only be used if your WaveLAN card has been 

equipped with a security feature. If you want to encrypt wireless data 

transmissions, set encryption to “on” and set the Encryption key. 

Only needed if Encryption Enable is “on”. All WaveLAN cards and 

WavePOINT access points must use the same encryption key (see also 

Chapter 3 of your WaveLAN/PCMCIA Card User's Guide). 

Fill in the same name as the one you entered in the “Computer Name” field of 

the “Network” window (see Figure 4 on page 3). 

Click “OK” to proceed with the installation process. When Windows 95 

prompts you to identify the location of the Windows 95 files, specify the drive 

and directories of the Windows Installation CD-ROM or diskettes. 

When Windows 95 has finished the copying of files, it will prompt you to 

restart your computer. 

If you would like to use your computer in multiple network configurations, 

select “NO”. Refer to “Using Multiple Hardware Profiles” on page 9, to verify 

the correct settings for the different hardware configurations. 

If you will be using your computer as a WaveLAN station only, 

1 Remove the WaveLAN software diskette from drive a:\ 

2 Click the “OK” button to restart your computer. 

Windows 95 will open a dialog box that enables you to enter a user name and 

a user password. The password you enter here will be the one used to log into 

the Windows 95 Network Neighborhood. 

If the Windows 95 Network Neighborhood will be running together with 

another Network Operating System running (e.g. Novell Netware) 

Windows 95, it is recommended to use the same user name and password as 

you will be using to access the Novell Netware environment. 

To view other computers in your workgroup, double-click the “Network 

Neighborhood” icon on the Windows 95 desktop. 

To view other workgroups in your network environment, double-click the 

“Entire Network” icon. This will display a list of other workgroups in the 

network environment.

parameters 

Figure 6 Network 

window 

If you cannot find other (WaveLAN) networked computers verify whether: 

• The other WaveLAN computers are powered up and logged on. 

• WaveLAN computers are using the same NWID or Domain ID, and the 

same network protocol. 

If there is a second Network Operating System running in your network 

environment, the “Entire Network” window, will also display available 

servers running under the second Network Operating System. 

If you click on these servers, you may be asked to enter your user name and 

password that apply to the other Network Operating System. 

Again, it is recommended to use the same user name and password for both 

Windows 95 and the other Network Operating system. Doing so, a next time 

you will log into the Windows 95 Network Neighborhood, the log-in to the 

other Network Operating System will be effected automatically. 

1 Click the Start button at the Windows 95 Taskbar and move the pointer to 

view Settings, Control Panel 

2 From the Control Panel window double-click the “Network” icon.

(see page 3 for a description of the parameters ). 

7 To view the network protocol settings , click the “Bindings” tab in the 

“Network” window. 

8 Double-click the “OK” button to quit the “Network” window. 



Local MAC addressing 

If you changed parameters in the “Network” window, Windows 95 may 

prompt you to re-boot your computer. 

The Windows 95 Installation procedure will by default use the Universal 

MAC Address to install your WaveLAN card. If you prefer to use Local MAC 

addressing proceed as follows: 

1 Execute step 1 to 7 of the procedure to “View or Change WaveLAN 

parameters”. 

2 Select the parameter “Station Address” 

3 Enter the Local Mac Address that is to be used for this WaveLAN card 

For more information on Universal and Local MAC addressing, see Chapter 3 

of the WaveLAN/PCMCIA Card User's Guide.

Figure 8 Create new 

hardware profiles 

Warning !! 

Using Multiple Hardware Profiles 

If you intend to use your computer in multiple network set-ups, such as 

Ethernet and WaveLAN network environments, you can use Windows 95 to 

define multiple hardware configurations for your computer. 

Using this powerful Windows 95 feature, each time you power up your 

computer, you will be asked first which hardware profile you would like to 

use for the current session. This will enable you to adapt quickly to situations 

where you may have a wireless network, a wired network or no network at 

all. 

The next example describes the procedure to create hardware profiles for both 

Ethernet and WaveLAN network environments. 

1 Use the right mouse button to click the “My Computer” icon that is 

located at the upper left of your windows screen, or desktop. 

2 Select Properties 

3 Select the “Hardware Profile” tab 

4 Select the “Original Configuration” or current configuration and click the 

copy button. (See Figure 8.) 

5 Enter a name for the new configuration : e.g. WaveLAN Profile 

6 Click the “OK” button 

This will create an exact copy of the current hardware profile. The next step 

will be to remove all devices that you do not want in the new hardware profile 

(e.g. remove the Ethernet adapter from the WaveLAN profile). 

1 From the “System Properties” window, select the “Device Manager” tab. 

2 Select the hardware item you want to remove from your new 

configuration (e.g. the Ethernet adapter). 

3 Click the remove button 

4 Windows 95 will prompt you to confirm the removal of the device. 

Make sure you select the “Remove from Specific Configuration” bullet 



Figure 9 

5 Use the scroll bar in the Configuration pull down menu to select the 

Hardware Profile from which the selected item should be removed (i.e. 

WaveLAN profile). 

6 Repeat this sequence for all items that need to be removed from a 

Hardware Profile configuration. 

7 When prompted to restart your computer, click the “OK” button. 

8 Select the hardware configuration that you will use to install WaveLAN. 

9 Resume the installation procedure for your WaveLAN card (go back to 

page 1). 

After installation, you are advised to check the correct settings for different 

adapter configurations once again.
