1. Network Implementation Using The product There are two possible types of wireless network configurations using the product: (1) Infrastructure (wireless network using an Access Point) Using the Client/Server or Master/Slave concept, an Access Point is used to link a wired network with wireless clients. Not only can the wireless clients access the wired network but they can also access each other via the Access Point.
- If you are using a fixed IP address: IP address, gateway address, and subnet mask info. To use the Dual-band Wireless LAN USB Adapter, the device must be equipped with an internal or external USB slot. You should have the latest drivers and utility software for the product (please visit our website for the latest drivers and utility software).
3. Installing the Dual-band WLAN USB Adapter The following explanation is based on installation of the Dual-band WLAN USB Adapter into a PC running the Windows XP operation system. Installation in PCs running Windows 98SE, Me, 2000 or XP may be slightly different than shown here. 3.1. Connect the Dual-band WLAN USB Adapter into the PC's USB slot. The PC will automatically detect the Dual-band WLAN USB Adapter and display the [Found New Hardware Wizard] window. 3.2.
3.4. Click on [Next] and the utility program will be automatically installed as shown in the following screen. 3.5. The following screen will appear when installation is completed. Click on [Finish] to successfully exit the installation process.
4. The Client Utility Program The following are explanations on how to configure and use the Client Utility program. How to Use the Utility Program After completing the above installation and configuration procedures, a new icon as shown below will automatically appear in the lower right tray bar. Double-clicking on the icon will display the following [Client Utility] window.
[Network] This page shows how the network is presently configured: network mode, information on the connected AP, TCP/IP, etc. This information cannot be modified in the Network screen. The “Current Status” window shows the signal quality, signal strength, channel, etc. between the client and AP. It is always in view regardless of which page (Network, Profile, Search, Option, Version) is selected within the Client Utility.
[Profile] This page is used to manage connection with Access Points. You can create different configuration profiles for connections with different APs and SSIDs. The advantage of saving different profiles is the easiness of quickly changing connections without having to configure the PC with every single variable each time a connection change is made. Also, when configuring TCP/IP via the Client Utility you do not need to reboot the PC as when TCP/IP configuration is done via Windows' Control Panel.
2) Select [Express Setup] and click on [Next]. The following screen will appear. Type in the new profile name for the new wireless connection. 3) Click on [Next] and the following screen will appear.
Select a “Network Mode” (Infrastructure or Ad-Hoc) and “SSID”. You do not need to change the default settings of "Power Save Mode" and "Roaming Optimization" unless there is a special need to do so. Refer below for further explanation of each mode. Reference Network Mode Infrastructure: You will need an 802.11b Access Point to use the device in Infrastructure mode. Because all communication will be done via the Access Point, the Access Point’s SSID must be used.
If you do not know the SSID of the devices you want to connect with or want to know the SSIDs of any wireless LAN devices operating in the vicinity, click on [Browse] and the following [Site Survey] screen will appear. Click on [Refresh] to update the list of available SSIDs in the vicinity. [Refresh] will scan the vicinity of a certain amount of time and display the scan results.
4. Click on [Next] and the following screen will appear. Click on [Apply this profile now] to immediately make this profile effective as the current profile and connect to the selected SSID. If you choose to only save the new profile without making it the current profile, do not select this option. 5. Click on [Save] and you will be taken back to the [Profile] page and the new profile automatically added to the “Profile List”.
n Remove To remove a profile from the “Profile List” select it and then click on [Remove]. n Apply If you want to change the current profile with another profile from the “Profile List”, select the desired profile and click on [Apply]. The new profile will immediately become the current profile and you will be connected with its SSID.
n Property Selecting a profile from the “Profile List” and clicking on [Property] will allow you to check and/or modify the properties of the selected profile. Clicking on [Property] will take you to the following screen. Each page in [Property] is explained below. General: In this page, you can verify the profile name of the current profile. Wireless Network: In this page, you can configure parameters such as Network Mode, SSID, and others.
WEP (Wired Equivalent Privacy): In this page, you can modify features of the WEP encryption system such as WEP Key, 64 or 128-bit encryption, etc. When using WEP encryption (available in 64 or 128-bit), only those APs and PCs using the same WEP Key are allowed to communicate with each other.
- Make key using PassPhrase: a WEP Key is automatically generated as you type in any PassPhrase of your choice. - Manual Input (ASCII): You generate your own WEP Key using ASCII characters (5 characters for 64-bit and 13 characters for 128-bit). - Manual Input (Hexadecimal): You generate your own WEP Key using hexadecimal characters (10 characters for 64-bit and 26 characters for 128-bit). Advanced: In this page, advanced hardware properties can be modified.
TCP/IP: In this page, you can modify the network's TCP/IP settings of your PC.
If you want to modify the TCP/IP, select the parameter "Use IP Changer" and the screen below will appear. Select "Use DHCP" if a dynamic IP is automatically assigned to you each time you connect to the network. Select "Use Static IP below" and type in the TCP/IP information if you are assigned a fixed IP address.
[Site Survey] This page shows a list of SSIDs in your vicinity. Information regarding each SSID is also shown: SSID, signal strength, signal channel, BSSID (MAC address), data rate, and WEP status (on or off). [Refresh] will scan the vicinity of a certain amount of time and display the scan results. [Strong Scan] will continuously scan the vicinity every 2.5 seconds until you click on [Stop], which appears in place of [Strong Scan] when scanning.
Selecting a network from the [Available Networks] list will enable the [Detail Info], [Connect] and [Add to profile] buttons. [Detail info] will display the following screen showing the selected device's configuration information. An alternative to clicking on [Detail info] is double-clicking on the SSID of choice. [Connect] will immediately connect you with the selected network.
[Add to profile] will have the same effect as clicking on [Add] in the [Profile] page (steps 4.8~4.12).
[Option] In this page you can configure various parameters as shown below: [Launch at windows startup] : Selecting this option will automatically start the Client Utility program whenever you start Windows. [Language] : You have the option to select the interface's language between English and Korean. After finishing your parameter settings, click on the [Apply Now] button to immediately apply them.
[Version] Software and Hardware information of the current client device being used by your PC are displayed in this page.
