5. Troubleshooting  
           
If you encounter any problems during the installation, or to confirm that the WLAN 11Mbps device is 
installed properly, please read the following troubleshooting section. 
 
 
 
In Windows 98:   
 
 
 
To check that the WLAN 11Mbps device is installed properly, please do the following: 
1. 
Go to START>SETTINGS>CONTROL PANEL>NETWORK.  Choose the Configuration Tab.  If you 
find the WLAN 11Mbps Adapter, it means the card is installed properly. If you see the Yellow 
Question-mark (?)
 means the resources are conflicting. (Please read further in this section for 
solutions.) 
-or- 
2. 
Right click on My Computer and select Properties.  Select the Device  Manager  and click on the 
Network Adapter. You will find the WLAN 11Mbps Adapter if it is installed successfully.  If you see the 
Yellow sign, the resources are
 
conflicting.  Click on the PCMCIA Card and then on the PCMCIA Card 
Service, you can see the
 
status of the PC card.  If there is a yellow sign either on the adapter or the PC 
card, please check the following. 
 
1. 
Check to see if your computer supports 3.3V Card. 
2. 
Check to see if your computer has a free IRQ.  If not, make an IRQ free by assigning the 
same IRQ to some devices, for example COM 1; COM 2 can be assigned the same IRQ 
values. 
3. 
Check that you have inserted the right card and have installed the proper driver.
 
Troubleshooting  (Continued) 
 
 
 
In Windows 2000:   
 
 
1. Check 
the 
Windows 2000 Diagnostics.  See if there is any conflict in the resource  allocation or 
the I/O Address, IRQ allocations.  If you find that the IRQ  or I/O Addresses are already assigned 
to some other devices, you must change that value.  I/O Address needs 40h byte length. 
 
2.  Go to the Control panel.  Double click on the PCMCIA Card and  you will see WLAN Adapter.  
Double clicking on that will show you the Card Information, driver name and the driver file.  You 
must confirm the name of the driver and the driver file as "prismnic.inf"  and "prismnds.sys".  If 
you do not find the names listed above, there are some problems and the driver is not installed 
properly.  Reinstall the driver. 
 
Note: Check the PnP BIOS setup menu and select no in case of the WLAN Adapter installation.
