Troubleshooting
This section describes methods which can be used to solve problems which may appear
during the installation and operation of the PCI/USB wireless network adapter. Please read the
description below for troubleshooting.
1. The PCI/USB adapter does not operate correctly.
• Replace the adapter in the computer’s PCI slot or USB port.
• Right-click the My Computer icon and select Properties. Select Device Manager
and locate the network adapter. Verify whether the adapter is installed correctly in
the system. A yellow exclamation mark means that a resource conflict has occurred.
Check the adapter’s status. If you notice a yellow exclamation mark, do the
following:
o Make sure that your computer has an available IRQ (Interrupt Request)
number.
o Make sure you have installed the right adapter and driver. If the adapter does
not work properly despite completing the above steps, remove it and proceed
as follows:
o Uninstall the adapter’s driver from the computer.
o Restart the computer, and then reinstall the hardware and software as
described in this manual.
2. No communications with other computers over Ethernet in infrastructure mode.
• Make sure that the computer with which the adapter is associated is switched on.
• Make sure that the card is configured to operate on the same channel and with the
same security options as other computers using infrastructure mode.
3. The computer with the adapter cannot connect to a wireless network and/or the
Internet.
• Check whether LEDs on the broadband modem indicate normal operation. If not, a
problem with the modem may have occurred.
• Check whether LEDs on the router indicate normal operation. If not, make sure the
router is connected to mains and that Ethernet cables are securely attached.
• Verify whether the IP address, subnet mask, gateway and DNS settings are
configured correctly for the network.
• When using the infrastructure mode, check whether the network ID (SSID) is
identical for clients and access points.
• In ad-hoc mode, both computers must have the same SSID. Please note that it may
be necessary for one of the clients to establish a BSS (Basic Service Set). Wait for
the settings to be synchronized between all clients. This will allow you to avoid
multiple BSSs being set by different computers at the same time, which may cause
several independent BSSs to exist instead of a single BSS containing multiple
clients.
• Check whether the wireless network connection is configured correctly.
• If data encryption is enabled, make sure appropriate keys are provided in both the
adapter’s and the access point’s configurations.
