Infrastructure operation mode allows user configure the WRE54G via setup wizard. z Password protected configuration or management sessions for web access z Built-in HTTP Server for setup and management via any browser easily z Support 64/128 bit WEP encryption. Chapter 2: Planning your Wireless Network The Repeater’s Functions Simply put, the Wireless-G Range Expander can increase the coverage area of an ESS. Network Topology A wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each computer in the WLAN uses a wireless device to connect to the network. Computers in a WLAN share the same frequency channel and SSID, which is an identification name for wireless devices. Ad-Hoc versus Infrastructure Mode Unlike wired networks, wireless networks have two different modes in which they may be set up: infrastructure and ad-hoc. An infrastructure configuration is a WLAN and wired LAN communicating to each other through an access point. An ad-hoc configuration is wireless-equipped computers communicating directly with each other. Choosing between these two modes depends on whether or not the wireless network needs to share data or peripherals with a wired network or not. If the computers on the wireless network need to be accessed by a wired network or need to share a peripheral, such as a printer, with the wired network computers, the wireless network should be set up in infrastructure mode. The basis of infrastructure mode centers around an access point, which serves as the main point of communications in a wireless network. Access points transmit data to PCs equipped with wireless network cards, which can roam within a certain radial range of the access point. Multiple access points can be arranged to work in succession to extend the roaming range. If the wireless network is relatively small and needs to share resources only with the other computers on the wireless network, then the ad-hoc mode can be used. Ad-hoc mode allows computers equipped with wireless transmitters and receivers to communicate directly with each other, eliminating the need for an access point. The drawback of this mode is that, in Ad-Hoc mode, wireless-equipped computers are not able to communicate with computers on a wired network. And, of course, communication between the wireless-equipped computers is limited by the distance and interference directly between them. Chapter 3: Getting to Know the Wireless-G Range Expander The Side Panel Auto configuration port is where you will connect the power adapter. Reset Button You can use an object, such as a stretched paper clip, to press the Reset button and then release the button to reset the device to its factory-default settings. The Top Panel The LEDs on the top panel of the Wireless-G Range Expander indicate the information about power and network activity. Power Blue. The Power LED lights up when the Wireless-G Range Expander is powered on. Link Blue. The Link LED lights whenever there is a successful wireless connection. Chapter 4: Connecting the Wireless-G Range Expander The Setup Wizard will take you through all the steps necessary to configure the Wireless-G Range Expander. Before you start it, your notebook or desktop computer must already be part of a wireless network. 1. Power on your Access Point and make sure cables are properly connected. 2. In order to configure the Wireless-G Range Expander you mush already be connected to a wireless Access Point. 3. Power on your Wireless-G Range Expander by connecting your Wireless-G Range Expander to a power outlet. 4. Once the Wireless-G Range Expander is powered on, you can access it in your wireless network. 5. Insert the Setup Wizard CD into the CD-ROM driver of your PC or notebook that has already be part of a wireless network. 6. The screen should appear on your monitor. If it does not, this means the auto-run is not functioning. Start the auto-run manually by clicking the Start button, selecting Run, and typing D:\setup.exe (if “D” is your CD-ROM drive). Click the Setup button to run the Setup Wizard. 7. Click the Next button to continue or Exit to exit the Setup Wizard. 8. The next screen to appear will display a list of the access points on your network, along with the status information for each access point. If there is only one access point on your network, it will be the only one displayed. If there are more than one displayed, select the Access Point you want to connect to. Once you have connected to an Access Point, the Setup Wizard will search for all of the Wireless-G Range Expanders on your network. 9. Click the Yes button to continue or No to exit the Setup Wizard. 10. The Security screen shows the WEP key. If you would like to use Wired Equivalent Privacy (WEP) encryption for your wireless network., enter the required information on the screen. z WEP. In order to utilize WEP encryption, select the WEP setting from the pull-down menu, 64-bit (10 hex digits) or 128-bit (26 hex digits). If you do not wish to utilize WEP encryption, make sure Disabled is selected. The Access Point’s WEP encryption is unique to Linksys and may conflict with other vendors’ WEP encryption. z Passphrase. Instead of manually entering WEP keys, you can enter a Passphrase. This Passphrase is used to generate one or more WEP keys. It is case-sensitive and should not be longer than 16 alphanumeric characters. (The Passphrase function is compatible with Linksys wireless products only. If you want to communicate with non-Linksys wireless products, you will need to enter your WEP keys manually on the non-Linksys wireless products.) 11. If you entered a passphrase, then the Key 1 field will display the automatically generated WEP key. If you did not enter a passphrase, then enter a WEP key in the Key 1 field. Each device in your wireless network must use the same WEP key for the network to function properly. z Key 1. WEP keys enable you to create an encryption scheme for wireless LAN transmissions. If the WEP key hasn’t been automatically generated, then manually enter a set of values. (Do not leave the field blank, and do not enter all zeroes. These are not valid key values.) If you are using 64-bit WEP encryption, then each key must consist of exactly 10 hexadecimal characters. If you are using 128-bit WEP encryption, then each key must consist of exactly 26 hexadecimal characters. Valid hexadecimal characters are “0”-“9” and “A”-“F”. 12. Next button to continue or Back to return to the previous page. 13. Select the Wireless-G Range Expander you want to configure. Click Yes to configure the Network Address Settings of the Wireless-G Range Expander. If you do not want to continue, click No. 14. You can manually set IP configuration. Enter an IP Address, Subnet Mask, Gateway, and Expander Name appropriate for your network. If you are unsure of these settings, you can skip this selection by just clicking on Next. 15. Click the Next button to continue or Back to return to the previous page. 16. The next screen will allow you to review your settings. If these settings are correct, click the Yes button to save these settings. If there are any problems with the settings, click the No button to exit the Setup Wizard. 17. Congratulations! At this point, the configuration performed with the Setup Wizard is complete. Click the Exit button to exit the Setup Wizard.
