Security

To prevent unauthorized wireless stations from accessing data transmitted over the network, the

Security section of the Configuration Utility offers secure data encryption, known as WEP (Wired Equivalent Privacy), to better protect your data transmissions.

Configuration

Description

Network mode

Configurable between 802.11 Ad-hoc and Infrastructure modes. In

802.11 Ad-hoc mode, the wireless nodes form their own local network where the end nodes communicate peer-to-peer without an Access Point. In Infrastructure mode, the wireless searches all available wireless channels to associate with an Access Point.

Channel

Specifies a channel only when using an Ad-hoc network mode.

Network Name (SSID)

Enter a 32-character (maximum) Service Set ID in this field; the characters are case sensitive. When the wireless node is operating in Ad-Hoc mode, this field operates as the Basic Service Set ID (BSSID). All wireless nodes in the same network should use the same BSSID.

When in Infrastructure mode, this field defines the Extended Service Set ID (ESSID). The ESSID assigned to the wireless node is required to match the Access Point ESSID in order for them to communicate.

To activate the WEP Encryption, make sure the Enable Encryption box displays a checkmark (as shown on previous page).

WEP Encryption options will be displayed, as shown on the previous page. You may make changes, as detailed here:

1. Select one of the two options:

Create with Passphrase or Manual Entry. A Passphrase

makes you easier to enable WEP because it automatically generates the WEP hexadecimal numbers for the key. If the wireless network Access Point uses a Passphrase, you can also use that here. Otherwise, you will have to manually enter the hexadecimal numbers.

2. Create with Passphrase option: pull down the Key Length options and select the 64-bit or 128-bit, then type in your Passphrase.

3. Manual Entry option:

• Pull down the Key Length options and select the 64-bit or 128-bit, encryption method.

• In the Encryption Keys fields, specify the WEP keys:

For 64-bit encryption:

Hexadecimal: 10 hexadecimal digits in the range of “A-F”, “a-f” and “0-9” (e.g. 11AA22BB33)

For 128-bit encryption:

Hexadecimal: 26 hexadecimal digits in the range of “A-F”, “a-f” and

“0-9” (e.g. 00112233445566778899AABBCC).

4. When you are done, click the Apply button and click OK for the changes to take effect.

Important Note: The WEP keys must be set up exactly the same on all wireless devices in

order to communicate with each other.

This table describes the options available from the Security section:

Advanced Settings

The advanced settings give you flexibility to control your MA521 card to adjust with an access point or other client devices in certain environment.

Security Description

Enable Encryption

Create with Passphrase

A Passphrase is use to automatically generate the WEP hexadecimal numbers for the key. If your wireless network Access Point uses a Passphrase, you can use that here.

Once you type in the Passphrase, the generated key will be shown before you click OK or Apply button.

Manual Entry

The WEP hexadecimal numbers are needed if a Passphrase is not used in the wireless Access Point but rather if the key is manually entered.

Key Length

The key length must be the same between all wireless nodes and Access Points in the same network. The possible values for the data encryption level are 64-bit and 128-bit. The 64-bit data encryption is also called 40-bit data encryption by some vendors.

Key3

Key4

The MA521 device uses a selected WEP key to encrypt and decrypt information. When set to 64-bit (also called 40-bit), or 128-bit data encryption mode, you may specify up to four different keys to encrypt wireless data.

Select one of the keys as a default key.

Enables the data encryption for the wireless node. If you disable the data encryption (by unchecking the box) then no encryption method will be used; this is also called Open System data encryption. To enable encryption is to use the Shared Key data encryption method.

This table describes the options available from the Security section:

Status Description

Transmit Rate

Power Saving

Power saving options are Off, Normal, and Maximum. Power saving is disable when Ad-Hoc mode is selected in the Network Mode field. When the Power Saving setting is Off, the adapter receives full power from the PC. When the setting is Normal, the driver turns off power to the MA521 Wireless PC Card for brief periods over briefly-spaced time intervals. When the setting is Maximum, the driver turns off power to the MA521 Wireless PC Card for longer periods over more widelyspaced time intervals.

Transmit Power

This option controls the Radio Frequency (RF) output power. Selects 100%, 50%, 25%, 12.5%, or Minimum.

Preamble Type

A long transmit preamble allows the receiver (MA521 Wireless PC Card) to lock into the received bit patterns more easily. A short transmit preamble provides better performance. Default: Auto (long & short).

Fragmentation Threshold

This is the packet length used for fragmentation. Packets larger than the size programmed in this field will be fragmented. The Fragmentation Threshold value must be larger than RTS Threshold value. The default value for Fragmentation Threshold is 2432.

The Transmit Rate field allows to define the data transfer rate. The default value if Fully Automatic. In this case, the best transfer rate is negotiated between this wireless node and access point or another wireless note that it is communicating with. Other option values for this field are 1, 2, 5.5 and 11 Mbps.

RTS/CTS Threshold

The packet size that wireless node uses to determine if it should use the CDMA/CD mechanism or the CSMA/CA mechanism for packet transmission. With the CSMA/CD transmission mechanism, the transmitting station sends out the actual packet as soon as it has waited for the silence period. With the CSMA/CA transmission mechanism, the transmitting station sends out a RTS packet to the receiving station, waits for the receiving station to send back a CTS packet before sending the actual packet data. The default value for RTS Threshold is 2432.

Profile Section

The Profile area allows you to set values for all parameters by selecting a previously defined profile.

To create a profile, in the Profile Name field, type a Profile Name; for example: Home, Office. When you are done, click the Save button in the Profile area, and click Apply. If one of the profiles is no longer used, display the name in the Profile Name field, then choose Delete. You can add and modify multiple profiles at any time.

Wireless Network Fundamentals

Wireless Network Configuration Ad-Hoc Mode (Peer-to-Peer Workgroup)

The Institute of Electrical and Electronics Engineers (IEEE) standard for wireless LANs (WLANs), 802.11 offers two methods for configuring a wireless network — Ad-Hoc and infrastructure. In an Ad-Hoc network, computers are brought together as needed; thus, there is no structure or fixed points to the network — each node can generally communicate with any other node. There is no Access Point involved in this configuration. It enables you to quickly set up a small wireless workgroup and allows workgroup members to exchange data or share printers as supported by Microsoft Networking in the various Windows operating systems. Some vendors also refer to ad-hoc networking as peer-to-peer workgroup networking.

In this configuration, network packets are directly sent and received by the intended transmitting and receiving stations. As long as the stations are within range of one another, this is the easiest and least expensive way to set up a wireless network.

To set up an Ad-Hoc workgroup operating with standard protocols, do the following:

• Set all stations to connect in Ad-Hoc mode (or Peer-to-Peer workgroup mode).

• Set all stations to use the same network name (or SSID).

• Set all stations to use the same wireless channel for communication.

• Set all stations to disable the WEP encryption key, or set all stations to use an identical

WEP encryption key.

Infrastructure Mode

With a wireless Access Point, you can put the wireless LAN into Infrastructure mode. It provides wireless connectivity to multiple wireless network devices within a fixed range or area of coverage, interacting with a wireless node via an antenna.

In the Infrastructure mode, the wireless Access Point converts airwave data into wired Ethernet data, acting as a bridge between the wired LAN and wireless clients. Connecting multiple Access Points via a wired Ethernet backbone can further extend the wireless network coverage. As a mobile computing device moves out of the range of one Access Point, it moves into the range of another. As a result, wireless clients can freely roam from one Access Point domain to another and still maintain seamless network connection.

Ad-Hoc

MA521 Wireless PC Card in a Notebook Computer

To set up an Infrastructure network operating with standard protocols, do the following:

• Set all wireless stations to connect in Infrastructure mode.

• Set all stations to use the same network name (or SSID).

• Set all wireless Access Points to use the same network name (or ESSID).

• Set all stations to disable the WEP encryption key, or set all stations to use an identical

WEP encryption key as used by the Access Point.

• Set up wireless channels used by individual Access Points. (It is not necessary to set channels on the stations as the stations will automatically scan through all channels for the nearest Access Point.)

Service Set Identification (SSID)

The Service Set Identification (SSID) is a thirty-two alphanumeric character (maximum) string identifying the wireless local area network. Some vendors refer to the SSID as network name. For stations to communicate with each other, all stations must be configured with the same SSID.

A wireless LAN consisting of nodes operating in Ad-Hoc configuration without an Access Point is called a Basic Service Set (BSS). All nodes in a BSS must use the same Basic Service Set ID (BSSID).

In an infrastructure configuration with Access Points, multiple BSS can be configured to form an Extended Service Set (ESS). In this configuration, the Access Points are configured with the same Extended Service Set ID (ESSID). Wireless clients configured with the same ESSID can freely roam from one Access Point domain to another and still maintain seamless connection to the network.

Authentication and WEP Encryption

The absence of a physical connection between nodes makes the wireless links vulnerable to information theft. To provide a certain level of security, IEEE 802.11 standard has defined two types of authentication methods, Open System and Shared Key. Open System authentication is a null algorithm. Shared Key authentication is an algorithm where both the transmitting node and the receiving node share an authentication key to perform a checksum on the original message. By default, IEEE 802.11 wireless devices operate in an open system network.

Wired Equivalent Privacy (WEP) data encryption is utilized when the wireless nodes or access points are configured to operate in Shared Key authentication mode. There are three shared key methods implemented in NETGEAR 802.11b solutions: the standard based 64-bit WEP data encryption and 128-bit WEP data encryption.

The 64-bit WEP data encryption method allows for a five-character (40 bits) input. Additionally, 24 factory-set bits are added to the 40-bit input to generate a 64-bit encryption key. (The 24 factory-set bits are not user configurable.) This encryption key will be used to encrypt/decrypt all data transmitted via the wireless interface. Some vendors may refer to the 64-bit WEP data encryption as 40-bit WEP data encryption since the user configurable key used in the encryption process is only 40 bits wide.

The 128-bit WEP data encryption method consists of 104 configurable bits. Similar to the 64-bit WEP data encryption method, the remaining 24 bits are factory set and not user configurable.

Wireless Channel Selection

802.11b

IEEE 802.11b wireless nodes communicate with each other using radio frequency signals in the ISM (Industrial, Scientific, and Medical) band between 2.4 GHz and 2.5 GHz. Neighboring channels are 5 MHz apart. However, due to spread spectrum effect of the signals, a node sending signals using a particular channel will utilize frequency spectrum 12.5 MHz above and below the center channel frequency. As a result, two separate wireless networks using neighboring channels (for example, channel 1 and channel 2) in the same general vicinity will interfere with each other. Applying two channels that allow the maximum channel separation will decrease the amount of channel cross talk, and provide a noticeable performance increase over networks with minimal channel separation.

Note: The available channels supported by the wireless products in various countries are different. For example, Channels 1 to 11 are supported in the U.S. and Canada, and Channels 1 to 13 are supported in Europe and Australia.

Channel Center Frequency Frequency Spread

1 2412 MHz 2399.5 MHz – 2424.5 MHz 2 2417 MHz 2404.5 MHz –2429.5 MHz 3 2422 MHz 2409.5 MHz –2434.5 MHz
