A TROUBLESHOOTING
USB ADAPTER INSTALLATION PROBLEMS
If your computer cannot find the WUS622C-A Wireless USB Adapter or the
network driver does not install correctly, check the following items:
◆Make sure the adapter is connected to the USB port. Check for any
hardware problems, such as physical damage to the adapter’s
connector.
◆Try the adapter in another USB port. If this also fails, try using another
WUS622C-A wireless adapter that is known to operate correctly.
◆Check for a defective computer or USB port by trying the adapter in
another computer that is known to operate correctly.
NETWORK CONNECTION PROBLEMS
If the Link/Activity LED on the USB adapter is not lit, or if you cannot
access network resources from the computer, check the following:
◆Make sure the correct software driver is installed. Try reinstalling the
driver.
◆Make sure the computer and other network devices are receiving
power.
◆The access point you want to connect to may not be functioning
correctly. Try using another access point.
◆If you cannot access a Windows service on the network, check that you
have enabled and configured the service correctly. If you cannot
connect to a particular server, be sure that you have access rights and
a valid ID and password.
◆If you cannot access the Internet, be sure you have currently
configured your system for TCP/IP.
If your wireless station cannot communicate with a computer on the
Ethernet LAN when configured for Infrastructure mode, check the
following:
APPENDIX A | Troubleshooting

◆Make sure the access point that the station is associated with is
powered on.
◆Check that the wireless settings (i.e., security, SSID, Channel) match
the access point or other stations to which you are attempting to
connect.
◆If you still cannot connect, change the access point and all the stations
within the BSS to another radio channel.

ACCESS POINT An internetworking device that seamlessly connects wired and
wireless
networks. Access points attached to a wired network, support the creation
of multiple radio cells that enable roaming throughout a facility.
AES Advanced Encryption Standard: An encryption algorithm that implements
symmetric key cryptography. AES provides very strong encryption using a
completely different ciphering algorithm to TKIP and WEP.
AUTHENTICATION The process to verify the identity of a client requesting network
access.
IEEE 802.11 specifies two forms of authentication: open system and
shared key.
BACKBONE The core infrastructure of a network. The portion of the network that
transports information from one central location to another central location
where it is unloaded onto a local system.
BSS Basic Service Set: A set of 802.11-compliant stations and an access point
that operate as a fully-connected wireless network.
BEACON A signal periodically transmitted from the access point that is used to
identify the service set, and to maintain contact with wireless clients.
GLOSSARY

BROADCAST KEY Broadcast keys are sent to stations using dynamic keying. Dynamic
broadcast key rotation is often used to allow the access point to generate a
random group key and periodically update all key-management capable
wireless clients.
DHCP Dynamic Host Configuration Protocol: Provides a framework for passing
configuration information to hosts on a TCP/IP network. DHCP is based on
the Bootstrap Protocol (BOOTP), adding the capability of automatic
allocation of reusable network addresses and additional configuration
options.
ENCRYPTION Data passing between the access point and clients can use encryption
to protect from interception and evesdropping.
ETHERNET A popular local area data communications network, which accepts
transmission from computers and terminals.
FTP File Transfer Protocol: A TCP/IP protocol used for file transfer.
HTTP Hypertext Transfer Protocol: HTTP is a standard used to transmit and
receive all data over the World Wide Web.

processing IP packets. ICMP is also used by routers to feed back
information about better routing choices.
IEEE 802.11B A wireless standard that supports wireless communications in the 2.4
GHz
band using Direct Sequence Spread Spectrum (DSSS). The standard
provides for data rates of 1, 2, 5.5, and 11 Mbps.
IEEE 802.11G A wireless standard that supports wireless communications in the 2.4
GHz
band using Orthogonal Frequency Division Multiplexing (OFDM). The
standard provides for data rates of 6, 9, 12, 18, 24, 36, 48, 54 Mbps. IEEE
802.11g is also backward compatible with IEEE 802.11b.
IEEE 802.11N A wireless standard that supports wireless communications in the 2.4

band using Orthogonal Frequency Division Multiplexing (OFDM). The
standard provides for data rates of 27, 54, 81, 108, 162, 216, 243, 270,
300 Mbps. IEEE 802.11n is also backward compatible with IEEE 802.11b/g.
IEEE 802.1X Port Authentication controls access to the switch ports by requiring
users to
first enter a user ID and password for authentication.
GLOSSARY
– 15 –
INFRASTRUCTURE An integrated wireless and wired LAN is called an infrastructure
configuration.
LAN Local Area Network: A group of interconnected computer and support
devices.
MAC ADDRESS The physical layer address used to uniquely identify network nodes.
NTP Network Time Protocol: NTP provides the mechanisms to synchronize time
across the network. The time servers operate in a hierarchical-masterslave
configuration in order to synchronize local clocks within the subnet
and to national time standards via wire or radio.
OPEN SYSTEM A security option which broadcasts a beacon signal including the
access
point’s configured SSID. Wireless clients can read the SSID from the
beacon, and automatically reset their SSID to allow immediate connection
to the nearest access point.
ODFM Orthogonal Frequency Division Multiplexing: OFDM allows multiple users to
transmit in an allocated band by dividing the bandwidth into many narrow
bandwidth carriers.
ROAMING A wireless LAN mobile user moves around an ESS and maintains a
continuous connection to the infrastructure network.
RTS THRESHOLD Transmitters contending for the medium may not be aware of each
other.
RTS/CTS mechanism can solve this “Hidden Node Problem.” If the packet
size is smaller than the preset RTS Threshold size, the RTS/CTS mechanism
will NOT be enabled.
SSID Service Set Identifier: An identifier that is attached to packets sent over
the wireless LAN and functions as a password for joining a particular radio
cell; i.e., Basic Service Set (BSS).
SHARED KEY A shared key can be used to authenticate each client attached to a
wireless
network. Shared Key authentication must be used along with the 802.11
Wireless Equivalent Privacy algorithm.
SNMP Simple Network Management Protocol: The application protocol in the
Internet suite of protocols which offers network management services.
GLOSSARY
– 16 –
SNTP Simple Network Time Protocol: SNTP allows a device to set its internal
clock based on periodic updates from a Network Time Protocol (NTP)
server. Updates can be requested from a specific NTP server, or can be
received via broadcasts sent by NTP servers.
TKIP Temporal Key Integrity Protocol: A data encryption method designed as a
replacement for WEP. TKIP avoids the problems of WEP static keys by
dynamically changing data encryption keys.
TFTP Trivial File Transfer Protocol: A TCP/IP protocol commonly used for software
downloads.
WI-FI PROTECTED
ACCESS
WPA employs 802.1X as its basic framework for user authentication and
dynamic key management to provide an enhanced security solution for
802.11 wireless networks.
WEP Wired Equivalent Privacy: WEP is based on the use of security keys and the
popular RC4 encryption algorithm. Wireless devices without a valid WEP
key will be excluded from network traffic.
PSK WPA Pre-shared Key: PSK can be used for small office networks that may
not have the resources to configure and maintain a RADIUS server, WPA
provides a simple operating mode that uses just a pre-shared password for
network access.
