FAQ
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 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 through Control Panel’s “Add or Remove
Programs”.
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.
36
Wireless Adapter
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.
4. 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
37
Wireless Adapter
device is located.
5. Nothing happens when I click ‘Open Config Utility’
1. Please make sure the wireless network card is inserted into your computer’s USB
port.
2. Reboot the computer and try again.
3. Remove the card and insert it into another USB port.
4. Remove the driver and re-install.
5. Contact the dealer of purchase for help.
6. I can not 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
3. ‘SSID’ field in ‘Site Survey’ function), you have to input correct SSID of the access
point you wish to connect. Please contact the owner of access point to ask for correct
SSID.
4. You have to input correct passphrase / security key to connect an access point with
encryption. Please contact the owner of access point to ask for correct passphrase /
security key.
5. The access point you wish to connect only allows network cards with specific MAC
address to establish connection. Please go to ‘Status’ menu and write the value of
‘MAC Address’ down, then present this value to the owner of access point so he / she
can add the MAC address of your network card to his / her access point’s list.
7. The network is slow / having problem when transferring large files
1. Move closer to the place where access point is located.
2. There could be too much people using the same radio channel. Ask the owner of the
access point to change the channel number.
Thank you for purchasing a quality Comfast Product.
