[. . . ] Open system authentication Null authentication method specified in the 802. 11 standard that performs no authentication checks on a wireless client before allowing it to associate. PPPoE (Point to Point Protocol over Ethernet) A method of allowing the authentication protocol adopted in telephone line connection (PPP) to be used over an Ethernet. Protocol A procedure or rule of delivering data among computers. Ordered data communication is allowed by making all conditions required for communication including the method of data transmission/reception and actions upon communication errors into procedures. 62 W i r e l e s s L A N U s e r 's G u i d e Shared key authentication 802. 11 network authentication method in which the AP sends the client device a challenge text packet that the client must then encrypt with the correct WEP key and return to the AP. If the client has the wrong key or no key, authentication will fail and the client will not be allowed to associate with the AP. Shared key authentication is not considered secure, because a hacker who detects both the clear-text challenge and the same challenge encrypted with a WEP key can decipher the WEP key. SSID (Service Set Identifier) Service Set Identifier, a 32-character unique identifier attached to the header of packets sent over a WLAN that acts as a password when a mobile device tries to connect to the BSS. The SSID differentiates one WLAN from another, so all access points and all devices attempting to connect to a specific WLAN must use the same SSID. A device will not be permitted to join the BSS unless it can provide the unique SSID. Because the SSID is broadcast in plain text, it does not supply any security to the network. Subnet mask TCP-IP network is controlled by being divided into multiple smaller networks (subnets). IP address consists of the subnet address and the address of each computer. Subnet mask defines how many bits of IP address comprise the subnet address. The same value shall be set among computers communicating with each other. TCP/IP (Transmission Control Protocol/Internet Protocol) A standard protocol of the Internet. Wi-Fi Wi-Fi, or Wireless Fidelity, is a set of standards for wireless local area networks (WLAN) based on the IEEE 802. 11 specifications. Certified products can use the official Wi-Fi logo, which indicates that the product is interoperable with any other product also showing that logo. 63 LifeBook P7000 Series Notebook - Section Five IP address information IP addressing is much more complicated than can be briefly explained in this document. You are advised to consult with your network administrator for additional information. If IP address is unknown, set IP address as follows: If you have an access point (DHCP server) on the network, set the IP address as follows: [Obtain an IP address automatically] A DHCP server is a server that automatically assigns IP addresses to computers or other devices in the network. There is no DHCP server for the AdHoc network. If the IP address is already assigned to the computer in the network, ask the network administrator to check the IP address to be set for the computer. If no access point is found in the network: An IP address is expressed with four values in the range between 1 and 255. Set the each computer as follows: The value in parentheses is a subnet mask. <Example> Computer A: 192. 168. 100. 2 (255. 255. 255. 0) Computer B: 192. 168. 100. 3 (255. 255. 255. 0) Computer C: 192. 168. 100. 4 (255. 255. 255. 0) : : Computer X: 192. 168. 100. 254 (255. 255. 255. 0) 64 W i r e l e s s L A N U s e r 's G u i d e WLAN Specifications Item Type of network Transfer rate Specifications Conforms to IEEE 802. 11a/802. 11b/g (Wi-Fi based)* (Automatic switching) IEEE 802. 11a/g: 54 Mbps maximum data rate IEEE 802. 11b: 11 Mbps maximum data rate Active frequency Number of channels Typical operating distances** 802. 11b/g: 2400~2473 MHz 802. 11a: 4900 ~ 5850 MHz 802. 11a: 8 independent channels 802. 11b/g: 11 channels, 3 non-overlapping channels 802. 11a: 40 ft. [. . . ] Under User Settings (Audio Settings and Taskbar Tips) you can set how OmniPass notifies the user of OmniPass events (e. g. , successful login, access denied, etc. ). The details of each setting under the Audio Settings and Taskbar Tips interfaces are self-explanatory. The Enrollment interface allows you to enroll fingerprints. To enroll additional fingerprints, click Enroll Authentication Device, and authenticate with OmniPass. [. . . ]
