Chapter 5 Troubleshooting 
This chapter provides solutions to problems that may occur during the installation and 
operation of the Wireless Cardbus/PCI/USB Adapter. Read the descriptions below to solve 
your problems.   
 
1.  The Wireless Cardbus/PCI/USB Adapter does not work properly. 
Reinsert the Wireless Cardbus/PCI/USB Adapter into your PC’s PCI slot/Cardbus slot/USB 
slot. 
Right click on My Computer and select Properties. Select the device manager and click on the 
Network Adapter. You will find the Adapter if it is installed successfully. If you see the yellow 
exclamation mark, the resources are conflicting. You will see the status of the Adapter. If there 
is a yellow question mark, please check the following: 
Make sure that your PC has a free IRQ (Interrupt ReQuest, a hardware interrupt on a PC.) 
Make sure that you have inserted the right adapter and installed the proper driver. If the 
Adapter does not function after attempting the above steps, remove the adapter and do the 
following: 
Uninstall the driver software from your PC. 
Restart your PC and repeat the hardware and software installation as specified in this User 
Guide. 
2.  I cannot communicate with the other computers linked via Ethernet in the 
Infrastructure configuration. 
Make sure that the PC to which the Adapter is associated is powered on. 
Make sure that your Adapter is configured on the same channel and with the same security 
options as with the other computers in the Infrastructure configuration. 
3.  What should I do when the computer with the Adapter installed is unable to 
connect to the wireless network and/or the Internet? 
Check that the LED indicators for the broadband modem are indicating normal activity. If not, 
there may be a problem with the broadband connection. 
Check that the LED indicators on the wireless router are functioning properly. If not, check 
that the AC power and Ethernet cables are firmly connected. 
Check that the IP address, subnet mask, gateway, and DNS settings are correctly entered for 
the network. 
In Infrastructure mode, make sure the same Service Set Identifier (SSID) is specified on the 
settings for the wireless clients and access points.   
In Ad-Hoc mode, both wireless clients will need to have the same SSID. Please note that it 
might be necessary to set up one client to establish a BSS (Basic Service Set) and wait briefly 
before setting up other clients. This prevents several clients from trying to establish a BSS at 
the same time, which can result in multiple singular BSSs being established, rather than a 
single BSS with multiple clients associated to it.
