Data Encryption
WEP is an authentication alogorithm that protects authorized WLAN users against
eavesdropping. WEP has been found to have some security problems. TKIP is a
temporary quick-fix method defined in the IEEE 802.11i standard to quickly overcome
the weaknesses in WEP security. AES has been developed to ensure the highest degree of
security and authenticity for digital information and is the most advanced solution
defined by IEEE 802.11i for security in the wireless network.
The security setting must be the same on the wireless network. The adapter supports
64/128-bit WEP, TKIP, and AES encryption functions.
Default Key ID Select one of the keys (1~4) as the encryption key.
Key Length Select either 64 or 128-bits. Larger key lengths provide
more security but reduce throughput.
Key 1 ~ Key 4 Fill in the text box by following the rules below:
64-bit: Enter 10 Hexadecimal digits (0, 1, 2 ~ 9, a, b, c ~ f)
as the encryption key. For example: 012345abcde
128-bit: Enter 26 Hexadecimal digits (0, 1, 2 ~ 9, a, b, c~f)
as the encryption key. For example:
0123456789abcdef0123456789.
NOTE: Once you have entered the key, the digits will
disappear and be replaced by * symbols. Make sure that
you record the key you entered.

11
Statistics
The transmission page gives you real time information about packet transmission and
receiving status. The Value represents the number of times the Counter Name has
occurred. In the example above, there have been 6607 packets received (Rx Packet
Count).

12
Troubleshooting
If you are experiencing trouble with your CB511WB, make sure that the card is firmly
seated in the cardbus slot.
•Make sure that the IP address, subnet mask, gateway, and DNS settings are correctly
entered for the network. Check with your operating system vendor if you are having
difficulty with these network settings. Remember that each computer must be
configured for networking and file sharing before the wireless network is in place.
•Make sure that you have selected the proper network connection mode. Use Ad Hoc
mode if you are connecting two wireless devices without an access point. Use
Infrastructure mode when you are using an access point.
•If you are in Infrastructure mode, make sure that the same SSID is specified for each
wireless client and access point. In Ad-Hoc mode, make sure both wireless clients
have the same SSID.
•If you have enabled encryption options, make sure that the correct encryption key has
been entered on each device. Make sure that the key selected on your CB511WB is the
same key entered on the other wireless device you want to connect to.
•If your wireless card appears as an “Unknown device” in the Device Manager,
remove the device from Device Manager and repeat the installation procedure.
•Make sure that there are no resource conflicts that may exist. Check your Device
Manager to make sure that device has installed properly.
•If you are experiencing intermittent network connections, try re-orienting the adapter.
See Appendix A: Installation Considerations on page 13 for more details.
•If there is no network association after your adapter wakes up from sleep mode, try
restarting your computer.

13
Appendix A: Installation Considerations
The CB511WB lets you use your laptop to access your WLAN from virtually anywhere,
but there are some things to keep in mind when attempting to set up a wireless
connection. The wireless signal range can be limited by the number, location, thickness,
and material of ceilings, walls or similar that the signal must pass through. To maximize
your wireless range, keep the following considerations in mind:
•Try to minimize the number of walls, ceilings, and similar between your wireless
devices. Each wall or ceiling the signal must cross can reduce the signal range by
up to 90 feet (30 m). Position your receiving devices so that the path between them is
as unobstructed as possible.
•The type of material the wireless signal must cross through also affects its range. A
solid metal door or concrete wall can decrease the signal’s range. Whenever possible,
position the adapters so that the signal can pass through drywall or open doors.
•Make sure that you are aware of the line the signal must take to travel between
devices. The angle that the signal is on as it travels through a door, wall, or ceiling
affects how thick the obstruction is. For example, if a wall is 1.5 feet thick and the
signal passes through it at a 45-degree angle, the signal must pass through 3 feet (1m)
of wall. At a 2-degree angle, the wall appears to be 42 feet (14m) thick. Always try to
position your devices so that the signal can travel at 90-degree angles.
•Electrical devices or appliances that generate RF noise (such as microwaves, electric
motors or computer monitors) can interfere with the wireless signal. Try to keep your
adapter at least 3-6 feet (1-2 m) away from these types of devices.

Appendix B: Setting Up A Wireless Ad Hoc Network
To install an Ad Hoc network, you need two computers and two wireless adapters.
Follow the instructions below to set up an Ad Hoc network between your two adapters,
using the product Quick Install or Instruction Guides for details when necessary.
1. Install your CB511WB network adapter, drivers, and utility program to your
notebook computer using the instructions provided in the Quick Install guide.
2. Install your second 802.11b wireless adapter, drivers, and utility program to your
other computer using the instructions provided in the Quick Install guide.
3. Using your configuration utility, set each adapter to Ad Hoc mode and make sure
that both adapters are on the same Channel and have the same SSID (see
Configuration on page 5 and 6 for details).
4. From your operating system software, make sure that the IP addresses assigned to
each computer are in the same range as (but not identical to) each other and
that the computers use the same subnet mask. Check with your operating system
vendor for information on setting up networking and file sharing.
For example, if your first computer has an IP address of 192.168.0.2 and a subnet
mask of 255.255.255.0, your second computer could be assigned an IP address of
192.168.0.3 with a subnet mask of 255.255.255.0.
5. When you have installed all the proper components, use the instructions on your
Quick Install or Instruction guide to connect your two devices.

15
Appendix C: Setting Up an Infrastructure Network
An Infrastructure network consists of both Wired and Wireless elements joined by a
Wireless Access Point. Follow the instructions below to set up an Infrastructure network
between your two adapters, using the product Quick Install or Instruction Guides for
details when necessary.
The example above assumes a previously established wired network with Internet
sharing supplied via router.
1. Connect your wireless access point to one of your router’s LAN ports using an
Ethernet cable. Use the access point’s instruction guide for installation details.
2. Install your wireless adapters, including their drivers and utility programs using
the instructions provided by the vendor.
3. From your configuration utility, make sure that your Network Type, SSID, Channel,
and Security Settings are all set to the same values for each device on your wireless
network. Also make sure that the IP addresses for each device are in the same range
as (but not identical to) each other and that the computers use the same subnet mask.
Note: You may be able to use your Wireless Access Point to configure these settings
on your wireless adapters. Check with your WAP’s documentation for details.

Glossary
802.11b: A family of IEEE-defined specifications for wireless networks. The 802.11b
standard supports data transfer rates up to 11 Mbits/sec in the 2.4 GHz band using DSSS
technology. Also known as WiFi.
Access Point: See wireless access point.
Ad Hoc: A wireless computer-to-computer LAN. An Ad Hoc network can consist of two
devices with wireless adapters, and does not require a WAP, router, or gateway. Also
known as peer-to-peer mode.
BSS (Basic Service Set): In Infrastructure mode, a BSS consists of a Wireless Access Point
and the adapters associated with it.
DSSS (Direct Sequence Spread Spectrum): A transmission technology used as the basis
for 802.11b wireless transmissions. DSSS helps increase a signal’s resistance to
interference and allows for some data bit recovery.
Encryption: The transformation of data into encoded ciphertext to ensure data
transmission can not be accessed by users outside the network. Encryption uses an
encryption algorithm and encryption keys to encode and decode the information. See
also WEP.
Encryption Algorithm: A formula used to convert data from understandable “plaintext”
into encoded “ciphertext.” Each algorithm uses a key (a string of bits) to perform the
calculations. The larger the key (most are 64 or 128-bits in length), the more difficult to
break the code.
ESS (Extended Service Set): In Infrastructure mode, the ESS consists of two or more
BSSes in the same subnet.
IBSS (Independent Basic Service Set): In Ad Hoc mode, an IBSS consists of two or more
wireless devices that communicate directly and do not use a wireless access point.
Infrastructure: A network configuration that typically combines both wired and wireless
elements. Wireless devices communicate with a WAP in order to communicate with each
other and with the wired elements of the network.
IP Address (Internet Protocol Address): An assigned number used to identify a computer
on a network. An IP address consists of four numbers less than 255 separated by periods
(for example, 192.168.2.1).
LAN (Local Area Network): A group of computers and devices connected together in a
relatively small area (such as a house or an office).
MAC Address (Media Access Control Address): A unique serial number that identifies a
piece of hardware connected to a network.
Plug and Play: A set of specifications that allows a computer to automatically detect and
configure hardware devices. With Plug and Play computers, any new hardware device
that is connected to a computer will automatically be recognized without the user having
to tell the computer the device has been added.

17
SSID (Service Set Identifier): A name that uniquely identifies a WLAN. In order for
wireless devices to communicate with each other, they must have the same SSID.
Subnet: An identifiably separate part of a network that is interconnected with, but still
independent from, the rest of the network. Subnets can help improve network security
and performance and typically use a router.
Subnet Mask: A technique used by the IP protocol to filter messages into a particular
network segment or subnet. Subnet masks are expressed as four decimal numbers
between 0 and 255 separated by periods. (Example: 255.255.255.1) It is used to create
private IP addresses for use within a particular network. Also known as a network mask.
WAN (Wide Area Network): A network that connects computers in geographically
separated areas. The Internet is an example of a WAN.
WAP (Wireless Access Point): A networking device that seamlessly connects wired and
wireless networks. Used in Infrastructure networks, a wireless access point is capable of
connecting to an Ethernet network as well as an 802.11 network.
WEP (Wired Equivalent Protocol): A security protocol designed to provide a wireless
network with the same level of security as a wired LAN. WEP offers protection primarily
by encrypting the information that flows between adapters.
