Select from the pull-down menu to change the Preamble type into Auto or Long. RTS Threshold: User can adjust the RTS threshold number by sliding the bar or key in the value directly. The default value is 2347. RTS/CTS Threshold is a mechanism implemented to prevent the “Hidden Node” problem. If the “Hidden Node” problem is an issue, users have to specify the packet size. The RTS/CTS mechanism will be activated if the data size exceeds the value you set. This value should remain at its default setting of 2347. Should you encounter inconsistent data flow, only minor modifications of this value are recommended. Fragment Threshold: User can adjust the Fragment threshold number by sliding the bar or key in the value directly. The default value is 2346. The mechanism of Fragmentation Threshold is used to improve the efficiency when high traffic flows along in the wireless network. If your Wireless LAN Adapter often transmits large files in wireless network, you can enter new Fragment Threshold value to split the packet. The value can be set from 256 to 2346.
- 17 - Authentication and Encryption tab: Authentication Type: There are seven type of authentication modes including Open, Shared, Leap, WPA, WPA-PSK, WPA2, WPA2-PSK, and WPA-None. • Open: If your access point/wireless router is using "Open” authentication, then the wireless adapter will need to be set to the same authentication type. • Shared: Shared Key is when both the sender and the recipient share a secret key. • LEAP: Light Extensible Authentication Protocol. It is an EAP authentication type used primarily in Cisco Aironet WLANs. It encrypts data transmissions using dynamically generated WEP keys, and supports mutual authentication (only with CCX mode enabled.) • WPA-PSK: WPA-PSK offers two encryption methods, TKIP and AES. Select the type of algorithm,
- 18 - TKIP or AES and then enter a WPA Shared Key of 8-63 characters in the WPA Pre-shared Key field. Encryption Type: For open and shared authentication mode, the selection of encryption type are None and WEP. For WPA, WPA2, WPA-PSK and WPA2-PSK authentication mode, the encryption type supports both TKIP and AES. WPA Pre-shared Key: This is the shared secret between AP and STA. For WPA-PSK and WPA2-PSK authentication mode, this field must be filled with character longer than 8 and less than 32 length. WEP Key: Only valid when using WEP encryption algorithm. The key must match with the AP’s key. There are several formats to enter the keys. • Hexadecimal (40bits): 10 Hex characters. • Hexadecimal (128bits): 32Hex characters. • ASCII (40bits): 5 ASCII characters. • ASCII (128bits): 13 ASCII characters. Show Password: Check this box to show the password you entered. 802.1x Setting: When user use radius server to authenticate client certificate for WPA authentication mode. 802.1x tab:
- 19 - EAP Method: • PEAP: Protect Extensible Authentication Protocol. PEAP transport securely authentication data by using tunneling between PEAP clients and an authentication server. PEAP can authenticate wireless LAN clients using only server-side certificates, thus simplifying the implementation and administration of a secure wireless LAN. • TLS / Smart Card: Transport Layer Security. Provides for certificate-based and mutual authentication of the client and the network. It relies on client-side and server-side certificates to perform authentication and can be used to dynamically generate user-based and session-based WEP keys to secure subsequent communications between the WLAN client and the access point. • TTLS: Tunneled Transport Layer Security. This security method provides for certificate-based, mutual authentication of the client and network through an
- 20 - encrypted channel. Unlike EAP-TLS, EAP-TTLS requires only server-side certificates. • EAP-FAST: Flexible Authentication via Secure Tunneling. It was developed by Cisco. Instead of using a certificate, mutual authentication is achieved by means of a PAC (Protected Access Credential) which can be managed dynamically by the authentication server. The PAC can be provisioned (distributed one time) to the client either manually or automatically. Manual provisioning is delivery to the client via disk or a secured network distribution method. Automatic provisioning is an in-band, over the air, distribution. For tunnel authentication, only support "Generic Token Card" authentication now. • MD5-Challenge: Message Digest Challenge. Challenge is an EAP authentication type that provides base-level EAP support. It provides for only one-way authentication - there is no mutual authentication of wireless client and the network. Tunnel Authentication: • Protocol: Tunnel protocol, List information including EAP-MSCHAP v2, EAP-TLS/Smart card, and Generic Token Card. • Tunnel Identity: Identity for tunnel. • Tunnel Password: Password for tunnel. Session Resumption: User can click the box to enable or disable this function. ID\PASSWORD tab:
