Figure 4.1.1 Wireless Settings

4.1 LAN Setting

Set up LAN connections.

4.1.1 Wireless

Wireless Function - Enable or disable wireless LAN computer communication.

Wireless Mode - Select one of the following:

- 11g(54M)-Turbo - Boosts 11g devices to turbo 54Mbps mode. 11b devices cannot connect.

- 11g(54M)/11b(11M)-Auto - Allows communication of 11g and 11b devices. Communication speed will drop to 11Mbps when 11b devices are connected. (Default setting)

- IIb(IIIM) Wi-Fi - Uses only the IEEE 802.IIb(IIMbps WiFi compatible) standard.

ESS-ID (SSID) - Allows administrator to alter the ESS-ID of the AirStation. To communicate with a specific AP only, the AP's ESS-ID must be entered in the client computer. The client computer looks for the specific AP (or ESS-ID) for wireless communication. Use up to 32 alphanumeric characters for the ESS-ID (case sensitive).

Note: Roaming - When multiple AirStations have an identical ESS-ID, WEP, (and channel in WDS mode), client computers may Roam between the AirStations.

Wireless Channel - Select the channel used for wireless communication. There are 11 overlapping channels. Channels 1, 6 and 11 are non-overlapping.

If there are multiple APs in close proximity using the same channel, there may be interference. In this case, change to a non-overlapping channel.

■ Note: This parameter is automatically set in the client computer.

Privacy Separator - Enable or disable communication between wireless clients. If you choose to use this feature, every wireless client that is associated to the AirStation will not be able to communicate with any other wireless clients.

■ Note: If this function is used, wired clients can still communicate with wireless clients.

BSS (Basic Service Set) Basic Rate Set - The transmission data rate between devices. If one device supports 2Mbps only, the data rate for the entire network should be limited to 2Mbps ("Default" selection). Otherwise, use 11Mbps Max ("All" selection).

Frame Bursting - This function increases 802.11g communication throughput by transferring packets more efficiently. The following conditions affect this function:

- The wireless LAN client adapter must support Frame Bursting (and it must be enabled).

- When several wireless clients use the Frame Bursting feature, throughput might not increase.

802.11g Protection - When this function is enabled, 802.11g protection mechanisms are started. These mechanisms should be used when mixed 11b and 11g clients use the wireless network. If only 11b or only 11g clients use the wireless network, then this function should be turned off. This function enables CTS (Clear-to-send).

DTIM Period - An access point transmits beacon signals to nearby clients at a preset interval. This parameter sets the beacon transmission interval time (1-255 sec.). Selection of a larger number may conserve energy for the client computer (when client power management is enabled), but may delay wireless communication. The default value of 1 is recommended.

Note: Setting the DTIM period too high can cause detrimental effects to the network and power saving clients may lose their connections entirely.

Wireless output power - Configure output power of AirStation. Decrease wireless output power to shrink the wireless communication range. The default setting of 32mW is recommended.

Figure 4.1.2 Wireless Security Settings

4.1.2 Wireless Security

Broadcast SSID - Enable or Disable the SSID (ESS-ID) from being broadcast. If enabled, the AirStation will not be found unless the specific AirStation's SSID is entered in the client computer.

Data Encryption - Disable to have no password protection of the wireless data.

Select encryption type of wireless data communication.

• Disabled - Disable data encryption.

- WEP - Uses WEP encryption. Encryption key should be entered.

- TKIP - Uses TKIP (Temporal Key Integrity Protocol) for data encryption.

- AES - Uses AES (Advanced Encryption Standard) for data encryption.

The encryption key is renewed every "Re-key interval" when "TKIP" or "AES" is selected.

Either "Disabled" or "WEP" can be selected if Network Authentication is disabled or if 802.1x is selected. Either "TKIP" or "AES" can be selected if the WPA configuration setting is "WPA" or "WPA-PSK".

WEP - When the WEP (Wired Equivalent Protection) encryption standard is implemented into a wireless network, a WEP key is used between the client and access point to successfully encrypt, transmit and decrypt data. For this reason, the same WEP key must be used for communication between the client and the AirStation. An access point and client may both carry multiple WEP keys. It is necessary for not only the WEP keys to match, but also the WEP key's order. If a wireless client cannot support multiple WEP keys, the AirStations must be configured to transmit key number 1 for a connection to take place.

Examples of WEP key:

64-bit ASCII: 5 digits of alphanumeric characters, "ab34Y"

128-bit ASCII: 13 digits of alphanumeric characters, "123456abcdef7"

■ Note: ASCII WEP keys are case sensitive.

64-bit HEX: 10 digits, using characters 0-9 and a-f, "00234ABCDE"

128-bit HEX: 26 digits, using characters 0-9 and a-f, "20123456789abcdeabcdeabcde"

TKIP - TKIP (Temporal Key Integrity Protocol) is a WEP expanded encryption technique. TKIP has greatly improved WEP's weaknesses by rotating secret keys between every packet. TKIP uses WPA-PSK (pre-Shared Key). Characteristics:

• The Initialization Vector is expanded from 24-bits to 48-bits.
• The Initialization Vector is randomized.
• Uses a different RC4 key for every packet.

AES - AES (Advanced Encryption Standard) is a next generation encryption technique discussed by the IEEE 802.11 committee. TKIP improves WEP's weakness, however AES also changes encryption method away from the weaker RC4 style. Throughput decreases 10 to 20 percent when TKIP software encoding is used. AES uses a hardware coprocessor and performance does not decrease when used. AES uses WPA-PSK (pre-Shared Key).

Characteristics:

• The US government uses the AES encryption method. AES encryption has not been broken/hacked to date.
• The hardware co-processor has less throughput loss than other forms of encryption.

WPA-PSK - TKIP and AES requires a WPA-PSK (Pre-shared key) for wireless client computers to authenticate with the AirStation and then encryption of the data takes place by TKIP or AES. The wireless computer's settings must use the same encryption method and key.

Input Method:

8 to 63 characters in ASCII or 64 digits hexadecimal key.

Example I: [airstation -WPA-PSK]

Example 2: [0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef

WPA Group Rekey Interval - When TKIP or AES is selected, the encryption key is renewed at this interval. This interval is in seconds; the range of acceptable values is 0-3600.

If 0 is entered, key is never renewed.

■ Note: The lower the rekey interval, the more often a rekey occurs. Setting a low rekey interval may affect performance.

IEEE802.1x/EAP authentication (WPA) - Configure Authentication and WPA Settings.

Do not authorize - Do not use any RADIUS Server based authentication.

Authorize - Authorized clients access this AirStation via RADIUS Server.

Use 802.1x/EAP to authorize every wireless client who wants to access the AirStation by using 802.1x/EAP and a RADIUS Server. The RADIUS server provides login information for every user establishing a more secure system than TKIP or other fixed encryption key methods. This also reduces the amount of necessary key maintenance.

A RADIUS server is necessary for IEEE802.1x/EAP authentication. Enter [RADIUS Server], {RADIUS Port} and [RADIUS Key] information.

RADIUS authentication

RADIUS Server - Enter RADIUS server IP address.

RADIUS Port - Enter port number for authentication.

RADIUS Key - Encryption key between RADIUS Sever and the AirStation. Enter same key as registered in the server. Use a 1 to 256 character alphanumeric code.

4.1.3 LAN Port

Set LAN side Ethernet settings

LAN Side IP address - Allows ad min is tra tor to specify a static IP and Subnet Mask for the LAN side of the AirStation.

Note: If the AirStation's IP address is changed, the confi guring computer's IP must be changed to the same range to continue confi guration. If the LAN IP is changed, restart the AirStation. (Section 4.4.10).

DHCP Server Function Simple Setting - Allows administrator to enable/disable the DHCP server function for the AirStation LAN side. Select Use to enable and Do not use to disable the function. Once Use is selected, the assigned IP address range can be specified. Enter the starting LAN IP address and total number of computers.

■ Note: If there is another DHCP server on the network, one either must be disabled or the IP range must be changed to avoid conflicts derived from overlapping DHCP scopes.

4.1.4 DHCP Server
