Appendix B: Glossary
802.11b - The 802.11b standard specifies a wireless product networking at 11
Mbps using direct-sequence spread-spectrum (DSSS) technology and operating
in the unlicensed radio spectrum at 2.4GHz, and WEP encryption for security.
802.11b networks are also referred to as Wi-Fi networks.
802.11g- specification for wireless networking at 54 Mbps using direct-sequence
spread-spectrum (DSSS) technology, using OFDM modulation and operating in
the unlicensed radio spectrum at 2.4GHz, and backward compatibility with IEEE
802.11b devices, and WEP encryption for security.
Ad-hoc Network - An ad-hoc network is a group of computers, each with a
Wireless Adapter, connected as an independent 802.11 wireless LAN. Ad-hoc
wireless computers operate on a peer-to-peer basis, communicating directly with
each other without the use of an access point. Ad-hoc mode is also referred to as
an Independent Basic Service Set (IBSS) or as peer-to-peer mode, and is useful
at a departmental scale or SOHO operation.
DSSS - (Direct-Sequence Spread Spectrum) - DSSS generates a redundant bit
pattern for all data transmitted. This bit pattern is called a chip (or chipping code).
Even if one or more bits in the chip are damaged during transmission, statistical
techniques embedded in the receiver can recover the original data without the
need of retransmission. To an unintended receiver, DSSS appears as low power
wideband noise and is rejected (ignored) by most narrowband receivers. However,
to an intended receiver (i.e. another wireless LAN endpoint), the DSSS signal is
recognized as the only valid signal, and interference is inherently rejected
(ignored).
FHSS - (Frequency Hopping Spread Spectrum) - FHSS continuously changes
(hops) the carrier frequency of a conventional carrier several times per second
according to a pseudo-random set of channels. Because a fixed frequency is not
used, and only the transmitter and receiver know the hop patterns, interception of
FHSS is extremely difficult.
Infrastructure Network - An infrastructure network is a group of computers or
other devices, each with a Wireless Adapter, connected as an 802.11 wireless
LAN. In infrastructure mode, the wireless devices communicate with each other
and to a wired network by first going through an access point. An infrastructure
wireless network connected to a wired network is referred to as a Basic Service
Set (BSS). A set of two or more BSS in a single network is referred to as an
Extended Service Set (ESS). Infrastructure mode is useful at a corporation scale,
or when it is necessary to connect the wired and wireless networks.
Spread Spectrum - Spread Spectrum technology is a wideband radio frequency
technique developed by the military for use in reliable, secure, mission-critical
communications systems. It is designed to trade off bandwidth efficiency for
reliability, integrity, and security. In other words, more bandwidth is consumed

49
than in the case of narrowband transmission, but the trade off produces a signal
that is, in effect, louder and thus easier to detect, provided that the receiver knows
the parameters of the spread-spectrum signal being broadcast. If a receiver is not
tuned to the right frequency, a spread-spectrum signal looks like background
noise. There are two main alternatives, Direct Sequence Spread Spectrum
(DSSS) and Frequency Hopping Spread Spectrum (FHSS).
SSID - A Service Set Identification is a thirty-two character (maximum)
alphanumeric key identifying a wireless local area network. For the wireless
devices in a network to communicate with each other, all devices must be
configured with the same SSID. This is typically the configuration parameter for a
wireless PC card. It corresponds to the ESSID in the wireless Access Point and to
the wireless network name. See also Wireless Network Name and ESSID.
WEP - (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-bit
or 128-bit or 152-bit shared key algorithm, as described in the IEEE 802.11
standard. To gain access to a WEP network, you must know the key. The key is a
string of characters that you create. When using WEP, you must determine the
level of encryption. The type of encryption determines the key length. 128-bit
encryption requires a longer key than 64-bit encryption. Keys are defined by
entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or ASCII
(American Standard Code for Information Interchange – alphanumeric characters)
format. ASCII format is provided so you can enter a string that is easier to
remember. The ASCII string is converted to HEX for use over the network. Four
keys can be defined so that you can change keys easily.
Wi-Fi - A trade name for the 802.11b wireless networking standard, given by the
Wireless Ethernet Compatibility Alliance (WECA, see http://www.wi-fi.net), an
industry standards group promoting interoperability among 802.11b devices.
WLAN - (Wireless Local Area Network) - A group of computers and associated
devices communicate with each other wirelessly, which network serving users are
limited in a local area.
WPA - (Wi-Fi Protected Access) - A wireless security protocol uses TKIP
(Temporal Key Integrity Protocol) encryption, which can be used in conjunction
with a RADIUS server.

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
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.
5. 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.
