[. . . ] TKIP replaces WEP with a new encryption algorithm that is stronger than the WEP algorithm, but that uses the calculation facilities present on existing wireless devices to perform encryption operations. One of the encryption methods supported by WPA, besides TKIP, is the Advanced Encryption Standard (AES). This is viewed as the optimal choice for security conscience organizations, but the problem with AES is that it requires a fundamental redesign of the NIC's hardware in both the station and the access point. TKIP is a pragmatic compromise that allows organizations to deploy better security while AES capable equipment is being designed, manufactured, and incrementally deployed. For more information on WPA security, see "WPA Wireless Security" on page B-8. 4-10 202-10026-01 Configuration User Manual for the NETGEAR 54 Mbps Wireless USB 2. 0 Adapter WG111 Networks Page The Networks Page scans and displays all available wireless networks in your area. Figure 4-8: Networks page The following information is displayed for each network scanned: · Wireless Network Name (SSID): Wireless Network Name (SSID) is the name assigned to a wireless network. This is the same as the SSID or ESSID configuration parameter. Note that, as a security measure, some wireless access points do not broadcast their SSID. In such cases, the SSID field will be blank even though the rest of the information will still be displayed. Channel: The channel determines which operating frequency will be used. Authentication: Identifies whether the wireless network requires authentication. Encryption: Identifies whether the wireless network requires WEP or WPA-PSK security settings. Transmit Rate: Lowering the output power level lets you reduce the chance of interference with other nearby access points, but reduces the range of your adapter. Wireless Mode: Select the wireless protocols you will use. Depending on your wireless adapter, you can choose one or both of the available 802. 11 wireless protocols. RTS/CTS Threshold: RTS is request to send and CTS is clear to send; their purpose is to avoid collisions. RTS/CTS will be enabled if the data frame size is larger than the threshold value set here. The maximum frame size is 2346 octets, so if the threshold is 2346, RTS/CTS will be disabled. Note: This setting is reserved for wireless testing and advanced configuration only. Do not change this setting unless you are sure you need to. The primary reason for implementing RTS/CTS is to minimize collisions between hidden stations. This occurs when users and access points are spread out and a high number of retransmissions occur on the wireless LAN. · · · Configuration 202-10026-01 4-15 User Manual for the NETGEAR 54 Mbps Wireless USB 2. 0 Adapter WG111 4-16 202-10026-01 Configuration User Manual for the NETGEAR 54 Mbps Wireless USB 2. 0 Adapter WG111 Chapter 4 Troubleshooting This chapter provides information about troubleshooting your NETGEAR 54 Mbps Wireless USB 2. 0 Adapter WG111.
