3.1 Profile In the “Profile”, you can view and manage the current using Available Point(s). You can Add, Delete, Edit, or Activate the current Available Point(s). Also you can duplicate the AP or set current AP as Default. Profiles Name: The Profiles List displays all the profiles and the relative settings of the profiles including Profile Name, SSID, and Channel…etc; preset to PROF* (* indicate 1,2,3,…) SSID: AP to Ad-hoc name. Channel: Channel in use for Ad-Hoc mode. Authentication: Authentication mode.
3.2 Link Status In this section, you can immediately monitor the current connected link status, such as Link Speed, Throughput, Link Quality, Signal Strength, Noise Level …etc. Status: Current connection status. If no connection, it will show Disconnected. Otherwise, the SSID and BSSID will show here. Extra Info: Display the link status in use. Channel: Display the number of the radio channel and the frequency used for the networking.
3.3 Site Survey When you open the Configuration Utility, the system will scan all the channels to find all the access points/stations within the accessible range of your adapter and automatically connect to the wireless device with the highest signal strength. From the “Site Survey”, all the network nearby will be listed. You can change the connection to another network or add one of the networks to your own profile list. SSID: Name of BBS of IBSS network.
Add to Profile: Add the selected AP to Profile setting. It will bring up profile page and save user’s setting to a new profile. [Connected Network] (1) When Raconfig first ran, it will select the best AP to connect automatically. (2) If user wants to connect to other AP, he can double-click mouse on the intended AP to make connection. (3) If the intended network has encryption other than “Not Use”, Raconfig will bring up the security page and let use input the appropriate information to make the connection.
Network Type: Infrastructure – This operation mode requires the presence of a wireless Access Point. All communication is done via the Access Point or Router. Ad-Hoc – Select this mode if you want to connect to another wireless station in the Wireless LAN network without through an Access Point or Router. Tx Power: If you want to lower the transmit power of the adapter for saving the power of the system, you can select the lower percentages from the list.
3.3.2 Authentication and Security Authentication Type: This setting has to be consistent with the wireless networks that the adapter intends to connect. Open: No authentication is needed among the wireless devices. Shared: Only Wireless device using a shared key (WEP Key identified) is allowed to connecting each other. Setup the same key as the wireless device that the adapter intends to connect. LEAP: LEAP is a pre-EAP, Cisco-proprietary protocol, with many of the features of EAP protocols.
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). AES is required to the corporate user or government users. The different between WPA and WPA2 is that WPA2 provides data encryption via the AES. In contrast, WPA uses Temporal Key Integrity Protocol (TKIP). WPA2-PSK – WPA2-PSK is also for home and small business.
64-bit – Input 10-digit Hex values (in the “A-F”, “a-f, and “0-9” range) or 5-digit ASCII characters (including “a-z” and “0-9”) as the encryption keys. For example: “0123456aef” or “test1” 128-bit – Input 26-digit Hex values (in the “A-F”, “a-f, and “0-9” range) or 13-digit ASCII characters (including “a-z” and “0-9”) as the encryption keys. For example: “01234567890123456789abcdef” or “administrator” 3.3.3 802.1x Setting-Certification The IEEE 802.
Authentication Type: The EAP authentication protocols this adapter has supported are included as follows. This setting has to be consistent with the wireless APs or Routers that the adapter intends to connect. PEAP and TTLS: PEAP and TTLS are similar and easier than TLS in that they specify a stand-alone authentication protocol be used within an encrypted tunnel. TTLS supports any protocol within its tunnel, including CHAP, MS-CHAP, MS-CHAPv2, PAP and EAP-MD5.
Tunneled Authentication: -- Protocol: When the authentication type is PEAP or TTLS, select a protocol to be used to build the encrypted tunnel. -- Identity: This is the protected user EAP Identity used for authentication. The identity specified may contain up to 63 ASCII characters, is case sensitive and takes the form of a Network Access Identifier, consisting of @. The user’s home realm is optional and indicates the routing domain.
Domain name must end in specified name: When selected, the server name field identifies a domain. The certificate must use a server name belonging to this domain or to one of its sub-domains (e.g. zeelans.com, where the server is blueberry.zeelans.com) but it may be any name used in the certificate name field. 3.4 Statistics Statistics page displays the detail counter information based on 802.11 MIB counters. This page translates the MIB counters into a format easier for user to understand.
3.5 Advanced In the “Advanced”, you can configure more advanced settings, for example: wireless Mode, B/G Protection, Tx Rate, Country Region Code…etc. Wireless Mode: Select wireless mode. 802.11 B only, 802.11 B/G mix, 802.11 B/G/N mix, 802.11 B/G mix, and 802.11 B/G/N mix modes are supported Select Your Country Region Code: The available channel differs from different countries. For example: USA (FCC) is channel 1-11, Europe (ETSI) is channel 1-13.
Tx BURST: The Burst enables the adapter to deliver the better throughput in the same period and environment. Enable TCP Window Size: The TCP Window is the amount of data a sender can send on a particular connection before it gets an acknowledgment back from the receiver that it has gotten some of it. When the Router or AP card is connecting to have set up the TCP Window, you can enable the parameter to meet the data size for the Router or AP connection. The larger TCP Window the better performance.
