Appendix C: FAQ
This chapter provides solutions to problems that may occur during the installation and
operation of the Wireless Adapter. Read the descriptions below to solve your problems.
1. I cannot communicate with the other computers linked via Ethernet in the
Infrastructure configuration.
1. Make sure that the PC to which the Adapter is associated is powered on.
2. 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.
2. What should I do when the computer with the Adapter installed is unable to
connect to the wireless network and/or the Internet?
1. Check that the LED indicators for the broadband modem are indicating normal
activity. If not, there may be a problem with the broadband connection.
2. 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.
3. Check that the IP address, subnet mask, gateway, and DNS settings are
correctly entered for the network.
4. In Infrastructure mode, make sure the same Service Set Identifier (SSID) is
specified on the settings for the wireless clients and access points.
5. 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.
6. 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.
3. I can’t find any wireless access point / wireless device in ‘Site Survey’ function.
1. Click ‘Rescan’ for few more times and see if you can find any wireless access
point or wireless device.
2. Please move closer to any known wireless access point.
3. ‘Ad hoc’ function must be enabled for the wireless device you wish to establish a
direct wireless link.
4. Please adjust the position of network card (you may have to move your computer
if you’re using a notebook computer) and click ‘Rescan’ button for few more times.
If you can find the wireless access point or wireless device you want to connect
by doing this, try to move closer to the place where the wireless access point or
wireless device is located.
4. I cannot establish connection with a certain wireless access point
1. Click ‘Add to Profile’ for few more times.
2. If the SSID of access point you wish to connect is hidden (nothing displayed in
