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 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
Manual.
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.
Check that the Network Connection for the wireless client is configured properly.
If Security is enabled, make sure that the correct encryption keys are entered on both the Adapter
and the access point.
