[. . . ] 802. 11 B/G mix ­ If you have a mix of 802. 11b and 802. 11g wireless stations in your network, it is recommended to setting the card to this mode. 802. 11 G only ­ This card can be compatible with both 802. 11g and 802. 11b wireless stations. If there are only 802. 11g wireless stations in the network, you can set the card to this mode. Ad Hoc Wireless Mode Preamble AirLive WT-2000USB User's Manual The preamble defines the length of the CRC block for communication 16 among wireless devices. If "Auto" mode is selected, the card will auto switch the preamble mode depending on the wireless devices the card is connecting to. Parameter RTS Threshold Description Minimum packet size required for an RTS (Request To Send). For packets smaller than this threshold, an RTS is not sent and the packet is transmitted directly to the wireless network. The value defines the maximum size of packets; any packet size larger than the value will be fragmented. If you have decreased this value and experience high packet error rates, you can increase it again, but it will likely decrease overall network performance. The channel setting should be the same with the network you are connecting to. Fragment Threshold Channel AirLive WL-1000CAM User's Manual 17 3. 2. 1. 2 Parameter Authentication and Security Description This setting has to be consistent with the wireless networks that the card intends to connect. Shared ­ Only wireless devices using a shared key (WEP Key identified) are allowed to connecting each other. Authentication Type Parameter Authentication Type Description LEAP ­ LEAP is a pre-EAP, Cisco-proprietary protocol, with many of the features of EAP protocols. Cisco controls the ability of other vendors to implement this protocol, so it should be selected for use only when limited vendor choice for client, access-point, and server products is not a concern. When you have set up LEAP authentication, you have to enter the user name and password of your computer. WPA ­ WPA provides a scheme of mutual authentication using either IEEE 802. 1x/Extensible Authentication Protocol (EAP) authentication or pre-shared key (PSK) technology. It provides a high level of assurance to enterprises, small businesses and home users that data will remain protected and that only authorized users may access their networks. For enterprises that have already deployed IEEE 802. 1x authentication, WPA offers the advantage of leveraging existing authentication databases and infrastructure. WPA-PSK ­ It is a special mode designed for home and small business users who do not have access to network authentication servers. In this mode, known as Pre-Shared Key, the user manually enters the starting password in their access point or gateway, as well as in each wireless stations in the network. WPA-PSK takes over automatically from that point, keeping unauthorized users that don't have the matching password from joining the network, while encrypting the data traveling between authorized devices. WPA2 ­ Like WPA, WPA2 supports IEEE 802. 1x/EAP authentication or PSK technology. It also includes a new advanced encryption mechanism using the Advanced Encryption Standard (AES). The difference between WPA and WPA2 is that WPA2 provides data encryption via the AES. In contrast, WPA uses Temporal Key Integrity Protocol (TKIP). AirLive WT-2000USB User's Manual 18 WPA2-PSK ­ WPA2-PSK is also for home and small business. The difference between WPA-PSK and WPA2-PSK is that WPA2-PSK provides data encryption via the AES. [. . . ] Ad hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation. What is Infrastructure An integrated wireless and wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for wireless access to central database, or wireless application for mobile workers. AirLive WL-1000CAM User's Manual 3. 5. 31 6. What is BSS ID A specific Ad hoc LAN is called a Basic Service Set (BSS). What is WEP WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40 bit shared key algorithm, as described in the IEEE 802 . 11 standard. [. . . ]
