However, if theres an error message shown, please choose Uninstall from the opened menu while right-clicking the USB Adapter item, to which a red or yellow icon is attached beside, in the Device Manager dialog box. Then restart your system and go through the installation procedures again. The following picture indicates a successful installation of the 802.11g/b WLAN USB Stick. 11 BBaassiiccss ooff tthhee AAttttaacchheedd CCoonnff iigguurraattiioo nn TT oooo ll In the following section, you will be guided through the basic 3-step workflows of configuring your network via the prompted attached configuration tool. Please read carefully to start the task. Step 1: Advanced Tab Firstly, choose this tab to define the network standard you wish to use. a) On the Advanced tab, choose Configuration Profile from Property. b) Define which network standard you intend to operate from the Value drop-down menu. WiFi Sepc is the default value. To use both 802.11b and 802.11g network standards, please choose Mixed. Step 2: Configuration Tab Click this tab to edit different profiles for different network configurations. a) Specify the network types as Access Point and Peer-to-Peer from the Network Type area. b) Type the identical SSID in the Network Name field to associate with access points or stations within the specified wireless LAN. c) Click Apply to establish the connection. d) If you wish to create a new profile for the current association, please enter texts in the Profile Name field and then click Save As to identify a new profile. You may switch between any existing profiles by clicking the arrow button at the right of the Profile Name field to open the pull-down menu and 12 then select an intended one from it. Tips: To obtain the general information on the status of currently connected entry, click the Status tab. Step 3: Security Tab To maintain the secure management in a wireless LAN environment, click the Security tab to define the encryption settings for a specific profile. This tab offers you various options concerning the so-called WEP (Wired Equivalent Privacy). a) Define the Authentication Type as WEP. b) Specify the key length from the two offered options: 64 bit or 128 bit from the Encryption (WEP security) drop-down menu. c) Now you may choose to edit WEP keys manually or create them via the passphrase of your wireless network. If you choose the Create Keys Manually option, you may directly enter up to 4 WEP keys for use in WEP encryption. To generate the WEP keys, please define the key entry method as Alphanumeric or Hexadecimal (for hexadecimal characters, only digits 0-9 and letters A-F are valid). d) Then edit the texts in the blank fields below, from Key 1 to Key 4, as the encryption codes. Note that these codes/keys shall be identical between the wireless nodes within the range and the access point only. e) Indicate which WEP key you intend to apply to activate the WEP encryption from the Use WEP Key drop-down menu. Make sure that the intended access point on the wireless network shares the same keys. 13 f) When the associated wireless network uses a passphrase to create WEP keys, you may select Create Keys with Passphrase, and then enter the passphrase string in the Passphrase filed to generate four encryption keys in the Key fields above. Note that only letters A-F are valid for the Passphrase feature. g) Indicate the Authentication Mode as Open, Shared, or AutoSwitch. Note that the value shall be corresponding to the currently associated access point. The Open option allows any station in the WLAN to receive and transmit data via the access point. The Shared option allows only the stations that use identical keys to associate with the access point. While choosing AutoSwitch, any station can associate with the access point either with or without encryption keys. h) Click Apply to active all the settings when you are done. Tips: To obtain the general information on the status of currently connected entry, click the Status tab. Other Tabs Besides the three tabs mentioned above, there are other six tabs that also provide you versatile functions. Please read the explanations below to learn more about each tab. The General Tab This tab reveals brief information on the 802.11 g/b WLAN USB Stick device itself. 14 The Status Tab Click the Status tab to appear the following display. From the window, the general information on the status of currently connected entry is presented. You may want to click the Rescan button to reinitiate the scanning process and update the status. Later the result of scanning will be renewed and displayed in the window. If you wish to stop the networking connection, click the Disable Radio button to stop scanning. However, if you are already in the disabled radio mode, you will find the Enable Radio button here instead. Click Enable Radio 15 to regain the link then. State Here displays the MAC Address of the current associated entry, which could be a connected access point in the Access Point mode or computers joining in the Peer-to-Peer network. Current Tx Rate This feature indicates the transmission rate of the current connection. Current Channel Here reveals the current channel operated in the wireless network. Note that the channel number differs as the radio scans any available channels in the Peer-to-Peer mode. Throughout (bytes/sec) This feature indicates the rates of transmitting (Tx) and receiving (Rx) data of your WLAN USB 802.11 g/b WLAN USB Stick within a short period of time; thus, the values vary on a time basis. Link Quality Link Quality is based on the percentage of successfully transmitted or received signal of the associated access point beacon within a limited period. The higher the percentage, the better the link quality. The bar graph beside also provides a visual interpretation of the current link quality. It is noted that the Link Quality and Signal Strength features only apply to the Infrastructure mode. They are inapplicable in the Peer-to-Peer mode since data will be transferred from many different computers. Signal Strength You may learn the received signal strength of the baseband processor of the beacon signal from the Signal Strength bar beside, and its also presented in terms of percentage. As the signal gets stronger, the signal percentage rate gets higher. It is noted that the Signal Strength and Link Quality features only apply to the Access Point mode. They are inapplicable in the Peer-to-Peer mode since data will be transferred from many different computers. The IBSS Tab If you, as a creator of the wireless network, are communicating with other stations via the IBSS mode to form Peer-to-Peer networks, click the IBSS (Independent Basic Service Set) tab to specify an operating radio frequency channel from the pull-down list under the IBSS Channel Selection section. 16 Note that the available channels differ from country to country, and the channel number must be the same between the entries/stations within the range, so that each can communicate with each other. To let the new configuration take effect, please choose Apply. On the other hand, while in the Access Point mode, you will find the channel number is the same as the associated access point. Thus, theres no need to manually set the value. The Domain Tab While in the 2.4GHz range, the network operation may differ from country to country, or domain to domain. This is because the 802.11d protocol was established. To have the operation normally processed, choose the Domain tab to change relevant settings. 17 802.11d Support 802.11d Support lets you operate multi-country roaming. To automatically adjust regulatory domain while operating network in different countries, choose either Strict or Flexible according to your need. If you choose None, the task will be terminated. Countries/Domains Define the regulatory domain from the drop-down menu of this command according to the country you are located in. More detailed information about the defined country/domain will be listed below afterwards. When you are done, remember to click Apply to let the new settings take effect. The About Tab This tab reveals general information on your 802.11 g/b WLAN USB Stick, including the following items:
18 Network Driver Displays the current version and released date of the 802.11 g/b WLAN USB Sticks driver. Configuration Utility Displays the current version and released date of the attached configuration tool. NIC Firmware Displays the current NIC card firmware version and the MAC (Media Access Control) address of your wireless card. It is consisted of 12-digit hexadecimal numbers (48 bits in length) to identify your computer's physical address on the local area network. The Driver Tab This tab provides you various commands used on the 802.11 g/b WLAN USB Sticks driver. 19 20
