3.2.1 Configure the Profile 3.2.1.1 Configuration Parameter Description Profile Name Define a recognizable profile name for you to identify the different networks. SSID The SSID (up to 32 printable ASCII characters) is the unique name identified in a WLAN. The ID prevents the unintentional merging of two co-located WLANs. You may specify a SSID for the adaptor and then only the device with the same SSID can interconnect to the adaptor. If you want to add the network n

Parameter Description PSM (Power Saving Mode) The power saving function is only available when the network type is in Infrastructure. CAM (Constantly Awake Mode) – The adaptor will always set in active mode. PSM (Power Saving Mode) – Enable the adaptor in the power saving mode when it is idle. Network Type Infrastructure – This operation mode requires the presence of an 802.11 Access Point. All communication is done via the Access Point or Router. Ad-Hoc – Select this mode i

Parameter Description RTS Threshold 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. Select a setting within a range of 0 to 2347 bytes. Minor change is recommended. Fragment Threshold 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 erro

Parameter Description Authentication Type 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 auth

Parameter Description Encryption Mode None – Disable the encryption mode. WEP – Enable the WEP Data Encryption. When the item is selected, you have to continue setting the WEP Encryption keys. TKIP – TKIP (Temporal Key Integrity Protocol) changes the temporal key every 10,000 packets (a packet is a kind of message transmitted over a network.) This ensures much greater security than the standard WEP security. AES – AES has been developed to ensure the highest degree of security a

The IEEE 802.1X specification describes a protocol that can be used for authenticating both clients and servers on a network. The authentication algorithms and methods are those provided by the Extensible Authentication Protocol (EAP), a method of authentication that has been in use for a number of years on networks that provide Point-to-Point Protocol (PPP) support as many internet service providers and enterprises do. When an AP acting as an authenticator detects a wireless stat
