Chapter 4 Troubleshooting
This chapter provides solutions to problems that may occur during the
installation and operation of the Wireless USB Adapter. Read the descriptions
below to solve your problems.
1. The Wireless USB Adapter does not work properly.
Reinsert the Wireless USB Adapter into your PC’s 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 BSS being established, rather than a single BSS
