1Chapter 1: IntroductionWelcomeWireless-G Ethernet BridgeChapter 1: IntroductionWelcomeThank you for choosing the Wireless-G Ethernet Bridge. The versatile Wireless-G Ethernet Bridge can make any wired Ethernet-equipped device a part of your wireless network. At home, use the Bridge to connect game consoles, set-top boxes, or computers to your Wireless-G network and its shared high-speed Internet connection. In the office, convert your Ethernet-wired printer, camera, notebook or desktop into a wireless networked device.It's completely driver-free, so it works on any platform and under any operating system! Since there's no drivers to load, setup is a snap—configure the network settings through your PC's web browser, then plug it into your device and go. And physical installation is simplified by support for Power Over Ethernet. With an optional POE Adapter, you can mount the Bridge wherever you want—power and data are both supplied through the Category 5 Ethernet cable.You can also use the Wireless-G Ethernet Bridge as a kind of “cable-less cable” to connect remote areas together. Maybe Shipping is all the way across the warehouse from Receiving. Or maybe you want to set up a home office in your detached garage. With a Wireless-G Ethernet Bridge in the garage, and another one (or a Wireless-G Access Point) in the house, you're connected—no digging trenches, and no overhead wires. Let the Wireless-G Ethernet Bridge from Linksys open up exciting new possibilities for your wireless network.Use the instructions in this Guide to help you set up and connect the Bridge. These instructions should be all you need to get the most out of the Wireless-G Ethernet Bridge.Ethernet: an IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium.802.11g: an IEEE wireless networking standard that specifies a maximum data transfer rate of 54Mbps, an operating frequency of 2.4GHz, and backward compatibility with 802.11b devices.

4Chapter 2: Planning Your Wireless NetworkNetwork TopologyWireless-G Ethernet BridgeChapter 2: Planning Your Wireless NetworkNetwork TopologyA 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.Ad-Hoc versus Infrastructure ModeUnlike 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 accessible 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 (see Figure 2-1). 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, and can be set up to communicate with your Ethernet hardware as well. 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. Figure 2-2 shows a typical scenario of four Wireless-G Ethernet Bridges in ad-hoc mode. Figure 2-3 shows a typical wireless bridging scenario using two Wireless-G Ethernet Bridges. Each wireless network is connected to a Wireless-G Ethernet Bridge through a switch. A separate notebook computer is equipped with a wireless network adapter and can communicate with either wireless network when it is configured with the appropriate SSID and channel.SSID: your wireless network’s name.LAN (Local Area Network): the computers and networking products that make up your local network.Figure 2-1: Infrastructure NetworkInfrastructure: a wireless network that is bridged to a wired network via an access point.Ad-hoc: a group of wireless devices communicating directly to each other (peer-to-peer) without the use of an access point.
5Chapter 2: Planning Your Wireless NetworkNetwork LayoutWireless-G Ethernet BridgeNetwork LayoutThe 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. The Camera will also communicate with network adapters, such as the Wireless-B and Wireless-G Network Adapters (model numbers WPC11 and WPC54G) for your laptop computers, Wireless-B and Wireless-G PCI Adapters (model numbers WMP11 and WMP54G) for your desktop PCs, and Wireless-B and Wireless-G USB Adapters (model numbers WUSB11 and WUSB54G) for your computers when you want to enjoy USB connectivity.With these, and many other, Linksys products, your networking options are limitless.

21Chapter 7: Using the Wireless-G Ethernet Bridge Web-based UtilitySetupWireless-G Ethernet BridgeRADIUSThis 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 TypeMD5Select 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.)• Default Transmit Key Select which WEP key (1-4) will be used when the Bridge sends data. Make sure that the receiving device (wireless client) is using the same key.• WEP Encryption. An acronym for Wired Equivalent Privacy, WEP is an encryption method used to protect your wireless data communications. WEP uses 64-bit or 128-bit keys to provide access control to your network and encryption security for every data transmission. To decode data transmissions, all devices in a network must use an identical WEP key. Higher encryption levels offer higher levels of security, but due to the complexity of the encryption, they may decrease network performance. Select 64 bits (10 hex digits) or 128 bits (26 hex digits).• 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 32 alphanumeric characters. (This Passphrase function is compatible with Linksys wireless products only and cannot be used with Windows XP Zero Configuration. If you want to communicate with non-Linksys wireless products or Windows XP Zero Configuration, make a note of the WEP key generated in the Key 1 field, and enter it manually in the wireless client.) After you enter the Passphrase, click the Generate button to create WEP keys. • Keys 1-4. WEP keys enable you to create an encryption scheme for wireless network transmissions. If you are not using a Passphrase, then manually enter a set of values. (Do not leave a key field blank, and do not enter all zeroes; they are not valid key values.) If you are using 64-bit WEP encryption, the key must be exactly 10 hexadecimal characters in length. If you are using 128-bit WEP encryption, the key must be exactly 26 hexadecimal characters in length. Valid hexadecimal characters are “0”-“9” and “A”-“F”.• User ID and Password. A user identification and password are required for your security. Enter the ID in the User ID field, then the password in the Password field.When finished making your changes on this tab, click the Apply button to save these changes.
