Wireless-G Ethernet Bridge Chapter 2: Planning Your Wireless Network 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 shared by the wireless devices belonging to the same wireless network.
Wireless-G Ethernet Bridge Network Layout The Wireless-G Ethernet Bridge is compatible with all 802.11b and 802.11g routers, such as model numbers BEFW11S4 and WRT54G, as well as access points, including model numbers WAP11 and WAP54G.
Wireless-G Ethernet Bridge Chapter 3: Getting to Know the Wireless-G Ethernet Bridge The Back Panel All connections to the Bridge are made through the ports on its back panel, shown in Figure 3-1. Reset When pressed, the Reset button resets the Bridge to its factory default settings. Important: If you reset the Wireless-G Ethernet Bridge, you will erase all of your settings (WEP encryption, wireless settings, etc.) and replace them with the factory defaults.
Wireless-G Ethernet Bridge The Front Panel The LEDs indicate network activity experienced by the Bridge. (See Figure 3-2.) Power Green. The Power LED will light up when the Bridge is powered on. While the Bridge is booting up and performing a self-test, the Power LED will flash. It will stop flashing and remain lit when the self-test has ended. Ethernet Green. The Ethernet LED will be lit steadily when the Bridge is connected to the wired network. The LED will flash when there is wired network traffic.
Wireless-G Ethernet Bridge Chapter 4: Connecting the Wireless-G Ethernet Bridge for Setup 1. Attach the Bridge’s antenna. 2. Plug the included Ethernet network cable into the LAN port on the back panel of the Bridge, shown in Figure 4-1. 3. Plug the other end of the Ethernet network cable into the RJ-45 port of the hub, switch, or PC you wish to use to configure the Bridge. 4. Plug the supplied power cable into the Power port on the back panel of the Bridge, shown in Figure 4-2.
Wireless-G Ethernet Bridge Chapter 5: Setting Up the Wireless-G Ethernet Bridge Now that you’ve connected the Wireless-G Ethernet Bridge to your wired network, you are ready to set it up. The Setup Wizard will guide you through all the necessary steps. 1. Insert the Setup CD-ROM into your PC’s CD-ROM drive. The Setup Utility should run automatically, and the screen in Figure 5-1 should appear. If it does not, click the Start button and choose Run. In the field that appears, enter D:\setup.
Wireless-G Ethernet Bridge 4. The screen shown in Figure 5-3 displays a list of Wireless-G Ethernet Bridges on your network, along with the status information for each Bridge. (If you have only one Bridge on your network, it will be the only one displayed.) Select the Bridge you are currently installing by clicking its name in the Selection box. Write down the IP address of the Wireless-G Ethernet Bridge, so you can use it to access the Web-based Utility later. Then click the Yes button.
Wireless-G Ethernet Bridge 7. The Wireless Settings screen, shown in Figure 5-6, will now appear. Enter your wireless network’s SSID. If you chose Ad-Hoc mode, select the channel at which the network broadcasts its wireless signal. If you have Wireless-G (802.11g) and Wireless-B (802.11b) devices in your network, then keep the default Network Mode setting, Mixed. If you have only Wireless-G devices, select G-Only. Then click the Next button to continue or the Back button to return to the previous screen.
Wireless-G Ethernet Bridge 9. The Security Settings (Optional) screen, shown in Figure 5-8, appears next. From the drop-down menu, select one of the wireless security mode options supported by the Bridge: WPA PSK (Pre-Shared Key) and WEP. (WPA stands for Wi-Fi Protected Access, which is a security standard stronger than WEP encryption. WEP stands for Wired Equivalent Privacy. If you do not want to use the security function, keep the default setting, Disabled. The security modes are briefly discussed below.
Wireless-G Ethernet Bridge 10. Review your settings on the Confirmation screen, shown in Figure 5-10. Write down the Bridge’s IP Address if you want to configure advanced settings through the Bridge’s Web-based Utility. Click the Yes button to save these settings. Click the No button to exit the Setup Wizard. Figure 5-10: Confirmation 11. The next screen, shown in Figure 5-11, shows that the configuration is complete.
Wireless-G Ethernet Bridge Chapter 6: Connecting the Wireless-G Ethernet Bridge for Network Use Connection to a Network Device 1. After configuration, unplug the power cable from the electrical outlet, and unplug the Ethernet network cable from the PC. 2. Plug the Ethernet network cable into the RJ-45 port on the Ethernet-ready network device you wish to add to the wireless network. 3. Plug the power cable into a local electrical outlet. The installation of the Wireless-G Ethernet Bridge is complete.
Wireless-G Ethernet Bridge Stand Option 1. The Bridge has eight rubber inserts, four on each side. Remove the two rubber inserts that are adjacent to the power port. 2. The Bridge includes two triangular stands. Insert a stand into an opening. Push the stand up to snap it into place. 3. Repeat step 2 using the second stand. 4. Place the Bridge in an appropriate location. 5. If necessary, adjust the antenna so that it points straight up in the air. (See Figure 6-2.
Wireless-G Ethernet Bridge Chapter 7: Using the Wireless-G Ethernet Bridge Web-based Utility Overview The Bridge is designed to function properly after you configure it using the Setup Wizard. However, if you would like to change these basic settings or make advanced configuration changes, use your web browser and the Wireless-G Ethernet Bridge Web-based Utility. This chapter explains how to use the Utility. Starting the Web-based Utility 1.
Wireless-G Ethernet Bridge Setup The Setup screen, shown in Figure 7-2, lets you configure the wired and wireless network settings for the Bridge. • Firmware - The version number of the Bridge’s firmware is displayed here. Firmware should be upgraded ONLY if you experience problems with the Bridge. Firmware updates are posted at www.linksys.com. • MAC Address - The MAC Address of the Bridge is displayed here. LAN • Device Name - You may assign any name to the Bridge.
Wireless-G Ethernet Bridge • Wireless Site Survey The Wireless Site Survey screen, shown in Figure 7-3 shows all the wireless networks detected by the Bridge and their general information. You can use this screen to connect to one of these networks. For each wireless network detected, the following information is displayed: • SSID - The network name. To join a wireless network, click its SSID. • MAC Address - The MAC address of the network’s access point. • Channel - The channel setting.
Wireless-G Ethernet Bridge If you click Edit Security Settings, The Security screen, as shown in Figure 7-5, will appear. From the dropdown menu, select one of the four wireless security modes supported by the Bridge: WPA Pre-Shared Key, WPA RADIUS, RADIUS, and WEP. (WPA stands for Wi-Fi Protected Access, which is a security standard stronger than WEP encryption. WEP stands for Wired Equivalent Privacy, while RADIUS stands for Remote Authentication Dial-In User Service) .
Wireless-G Ethernet Bridge WPA Pre-Shared Key WPA gives you TKIP for the encryption method. Enter a WPA Shared Key of 8-32 characters. (See Figure 7-6.) Enter a key shared between the Bridge and the server. Click the Apply button to save your changes. If your page doesn’t automatically refresh itself, then click the Refresh button of your web browser. Click the View Log button to view a log. The Log Table screen appears in Figure 7-7. The log shows the authentication process.
Wireless-G Ethernet Bridge RADIUS This option features WEP used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Router.) It offers three authentication methods: MD5, TLS, and TTLS. EAP Type MD5 Select a Default Key (choose which Key to use), and a level of WEP encryption, 64 bits 10 hex digits or 128 bits 26 hex digits. Then either generate a WEP key using a Passphrase or enter the WEP key manually. (See Figure 7-8.
