Computers in a wireless LAN must be configured to share the same radio channel. The Instant Wireless's'' Series adapters provide access to a wired LAN for wire- less workstations. An integrated wireless and wired LAN is called an Infrastructure configuration. A group of Instant Wireless*" Series adapter users and an Instant WirelessTM Wireless Network Access Point compose a Basic Service Set (BSS). Each Instant Wireless"" Series adapter PC in a BSS can talk to any computer in a wired LAN infrastructure via the Instant Wireless"" Wireless Network Access Point. An infrastructure configuration extends the accessibility of an Instant Wireless"" Series adapter PC to a wired LAN, and doubles the effective wire- less transmission range for two Instant Wireless"" Series adapter PCs. Since the Wireless Network Access Point is able to forward data within its BSS, the effective transmission range in an infrastructure LAN is doubled. Roaming Infrastructure mode also supports roaming capabilities for mobile users. More than one BSS can be configured as an Extended Service Set (ESS). This con- tinuous network allows users to roam freely. All PCs equipped with an Instant Wireless*" Series adapter must be configured with the same SSID and use the same radio channel. Before enabling a network with roaming capability, choosing a feasible radio channel and optimum Wireless Network Access Point position is recommend- ed. Proper Wireless Network Access Point positioning combined with a clear radio signal will greatly enhance performance. 2 3 EFTA00578363 Instant Wireless" Series Wireless Network Access Point Chapter 3: Getting to Know the Wireless Network Access Point The Wireless Network Access Point's Ports The Access Point's ports, where a network cable is connected, am located on the Access Point's rear panel. Figure 3-1 Dipole Antenna Connectors These two round connections are where the antennae are connected to the Access Point. LAN Power Reset Button This LAN (Local Area Network) port connects to Ethernet network devices, such as a hub, switch, or router. The Power port is where you will connect the power adapter. Them are two ways to Reset the Access Point's factory defaults. Briefly press the Reset Button for approximately ten seconds, or use the Password tab of the Access Point's Web-Based Utility. Important: Resetting the Access Point will erase all of your settings (WEP Encryption. Wireless and LAN settings, etc.) and replace them with the factory defaults. The Wireless Network Access Point's LEDs Figure 3-2 Power ACT LINK Red. The Power LED lights up when the Access Point is powered on. Green. If the LED is flickering, the Access Point is actively sending or receiving data to or from one of the devices on the network. Amber. The LINK LED serves two purposes. If the LED is continuously lit up, the Access Point is successfully connect- ed to a device through the LAN port. If the LED is flicker- ing, it is an indication of any network activity. 4 5 EFTA00578364 Instant Wireless" Series Wireless Network Access Point Chapter 4: Connecting the Wireless Network Access Point I. Locate an optimum location for the Access Point. The best place for the Access Point is usually at the center of your wireless network, with line of sight to all of your mobile stations. 2. Fix the direction of the antenna. Try to place it in a position which can best cover your wireless network. Normally, the higher you place the anten- na, the better the performance will be. The antenna's position enhances the receiving sensitivity. Both antennae should be perpendicular to the ground and parallel to each other. 3. Connect a standard Ethernet network cable to the Access Point. Then, connect the other end of the Ethernet cable to a switch or hub. The Access Point will then be connected to your 10/100 Network. 4. Connect the AC Power Adapter to the Access Point's Power Socket. Only use the power adapter supplied with the Access Point. Use of a differ- ent adapter may result in product damage. Now that the hardware installation is complete. proceed to Chapter 5: Setting Up the Wireless Network Access Point for directions on how to setup the Access Point. Note: In order for all other wireless devices to communicate with the Access Point. those devices must be operating in the Infrastructure Mode. If any wireless devices are configured in the Ad Hoc Mode, they will not be recognized by the Access Point. Chapter 5: Setting Up the Wireless Network Access Point Have You: Connected the Access Point to a hub, switch or router on your wired network as shown in Chapter 4: Connecting the Now that you've connected the Access Point to your wired network, you are ready to begin setting it up. This Setup Wizard will take you through all the steps necessary to get the Access Point connecting your wireless network to your wired network and communicating more efficiently. Note: While the Access Point has been designed to work correct- ly right out of the box, setting it up on a wireless computer will require you to use the Linksys default settings. These settings can then be changed with the Web-based Browser Utility. 1. Insert the Setup Wizard CD into your PC's CD-ROM drive. Optimally. your PC should be on your wired network. 2.

SETTING THE AP MODE: The Access Point offers four modes of operation: Access Point, Access Point Client, Wireless Bridge, and Wireless Bridge Point to MultiPoint. For all bridg- ing modes, make sure the channel, SSID, and WEP keys are the same. • Access Point - The Operational Mode is set to Access Point by default. This connects your wireless PCs to a wired network. In most cases, no change is necessary. • Access Point Client - When set to Access Point Client mode. the Access Point Client is able to talk to one remote access point within its range. This mode allows the Access Point Client to act as a client of a remote access point. The Access Point Client cannot communicate directly with any wireless clients. A separate network attached to the Access Point Client can then be wirelessly bridged to the remote access point. Enter the required LAN MAC address of the remote access point 16 17 EFTA00578370 Instant Wireless TM Series Wireless Network Access Point • Wireless Bridge - If you are trying to make a wireless connection between two wired networks, as shown in Figure 6-5, select Wireless Bridge. This mode connects two physically separated LAN segments with two Access Points. To configure a Wireless Bridge environment, click Wireless Bridge and enter the Remote Bridge LAN MAC Address of the remote Access Point. The remote Access Point also needs to be set up as a Wireless Bridge. Note: All devices on each wired network must be connected through a hub or switch. Note: In Wireless Bridge mode, the Access Point can ONLY be accessed by another access point in Wireless Bridge mode. In order for your other wireless devices to access the Access Point. you must reset it to Access Point mode. The two modes arc mutually exclusive. • — UM Cr dip a Figure 6-5 a • Wireless Bridge Point to MultiPoint- If you are frying to make a wireless connection between more than two wired networks, as shown in Figure 6- 6, select Wireless Bridge Point to MultiPoint. This mode allows you to construct a network that has multiple Access Points bridging wirelessly. To configure a Wireless Bridge Point to MultiPoint environment, click Wireless Bridge Point to MultiPoint for the Access Point used in LAN I. No MAC Address binding is needed. Then, set the Access Points in LAN 2 and LAN 3 to Point to Point, and have them look for the MAC Address of Only one of the Access Points must be in Point to MultiPoint mode. For all other bridged Access Points. select the Point to Point option. and enter the Remote LAN MAC Address of the Access Point set to Point to MultiPoint. Note: Linksys recommends bridging no more than three remote LANs in Wireless Bridge Point to MultiPoint mode. Bridging addi- tional remote LANs will result in a significant decrease in bandwidth.

In most cases, these settings do not need to be changed. • Beacon Interval. This value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Access Point to keep the network syn• chronized. A beacon includes the wireless LAN service area, the AP address, the Broadcast destination addresses, a time stamp, Delivery Traffic Indicator Maps, and the Traffic Indicator Message (TIM). • RTS Threshold. This value should remain at its default setting of 2,432. Should you encounter inconsistent data flow, only minor modifications are recommended. 24 25 EFTA00578374 Instant Wireless" Series Wireless Network Access Point • Fragmentation Threshold. This specifies the maximum size a data pack- et will be before splitting and creating a new packet and should remain at its default setting of 2,346. A smaller setting means smaller packets, which will create more packets for each transmission. Only minor modifications of this value are recommended. • DTIM Interval. This value indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast mes- sages. When the Access Point has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Access Point Clients hear the beacons and awaken to receive the broadcast and multicast messages. • Transmission Rates. The basic transfer rates should be set depending on the speed of your wireless network. You must select 1-2 (MBps) if you have older 802.11 compliant equipment on your network, such as wireless adapters that support only 1 or 2 Mbps. Selecting 1.2 (MBps), however, does not limit the basic transfer rates of faster adapters. • Preamble Type. The preamble defines the length of the CRC block for communication between the Access Point and a roaming Network Card. (High network traffic areas should use the shorter preamble type.) Select the appropriate preamble type and click the Apply button to set it. All wire- less points (nodes) on your network should use the same preamble type. • Authentication Type. You may choose between Open System. Shared Key. and Both. The Authentication Type default is set to Open System. Shared Key is when both the sender and the recipient share a secret key. All points on your network must use the same authentication type. It is rec- ommended that you use the default setting. • Antenna Selection. This selection is for choosing which antenna transmits data. By default, the Diversity Antenna selection, used to increase recep- tion, is chosen. • SSID Broadcast. For security purposes, this selection can be disabled, allowing only those wireless network cards with the Access Point's SSID to communicate with the Access Point. By default, this selection is enabled, allowing all wireless network cards in your wireless network to communi- cate with the Access Point. Important: The Access Point will not he recognized by "site-sur- vcy" utilitics. such as the Microsoft' Window? XP Zero Configuration Utility, if SSID Broadcast is disabled.

Read the description below to solve your problems. If you can't find an answer here, check the Linksys web- site at www.linksys.com. Frequently Asked Questions Can the Access Point act as my DHCP Server? No. The Access Point is nothing more than a wireless hub, and as such, cannot be configured to handle DHCP capabilities. Can I run an application from a remote computer over the wireless net- work? This will depend on whether or not the application is designed to be used over a network. Consult the application's user guide to determine if it supports oper- ation over a network. Can I play multiplayer games with other users of the wireless network? Yes, as long as the game supports multiple players over a LAN (local area net- work). Refer to the game's user guide for more information. What is the IEEE 802.11b standard? The IEEE 802.11b Wireless LAN standards subcommittee is formulating a standard for the industry. The objective is to enable wireless LAN hardware from different manufacturers to communicate. What IEEE 802.11 features are supported? The product supports the following IEEE 802.11 functions: • CSMAICA plus Acknowledge protocol • Multi-Channel Roaming Automatic Rate Selection RTS/CTS feature Fragmentation Power Management What is Ad-hoc? An Ad-hoc wireless LAN is a group of computers. each with a WLAN adapter, connected as an independent wireless LAN. An Ad-hoc wireless LAN is appli- cable at a departmental scale for a branch or SOHO operation. What is Infrastructure? An integrated wireless and wired LAN is called an Infrastructure configura- tion. Infrastructure is applicable to enterprise scale for wireless access to a cen- tral database, or wireless application for mobile workers. What is Roaming? Roaming is the ability of a portable computer user to communicate continu- ously while moving freely throughout an area greater than that covered by a single Access Point. Before using the roaming function, the workstation must make sure that it is the same channel number as the Access Point of the dedi- cated coverage area. To achieve true seamless connectivity, the wireless LAN must incorporate a number of different functions. Each node and Access Point, for example, must always acknowledge receipt of each message. Each node must maintain contact with the wireless network even when not actually transmitting data. Achieving these functions simultaneously requires a dynamic RF networking technology that links Access Points and nodes. In such a system, the user's end node under- takes a search for the best possible access to the system. First, it evaluates such factors as signal strength and quality, as well as the message load currently being carried by each Access Point and the distance of each Access Point to the wired backbone. Based on that information, the node next selects the right Access Point and registers its address. Communications between end node and host computer can then be transmitted up and down the backbone. As the user moves on, the end node's RF transmitter regularly checks the sys- tem to determine whether it is in touch with the original Access Point or whether it should seek a new one. When a node no longer receives acknowl- edgment from its original Access Point, it undertakes a new search. Upon find- ing a new Access Point, it then re-registers, and the communication process continues. What is BSS ID? A specific Ad-hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be configured with the same BSS ID. What is ESSID? An Infrastructure configuration could also support roaming capability for mobile workers. More than one BSS can be configured as an Extended Service Set (ESS). Users within an ESS could roam freely between BSSs while main- taining a continuous connection to the wireless network stations and Access Points. 28 29 EFTA00578376 Instant Wireless TM Series Wireless Network Access Point What is ISM band? The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available worldwide. This presents a truly revolutionary opportunity to place convenient high speed wireless capabilities in the hands of users around the globe. What is Spread Spectrum? Spread Spectrum technology is a wideband radio frequency technique devel- oped by the military for use in reliable, secure, mission-critical communica- tions systems. It is designed to trade off bandwidth efficiency for reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband transmission, but the trade-off produces a signal that is, in effect, louder and thus easier to detect, provided that the receiver knows the parameters of the spread-spectrum signal being broadcast. If a receiver is not tuned to the right frequency, a spread-spectrum signal looks like background noise. There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS). What is DSSS? What is FHSS? And what are their differences? Frequency Hopping Spread Spectrum (FHSS) uses a narrowband carrier that changes frequency in a pattern that is known to both transmitter and receiver. Properly synchronized, the net effect is to maintain a single logical channel. To an unintended receiver, FHSS appears to be short-duration impulse noise. Direct Sequence Spread Spectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted. This bit pattern is called a chip (or chipping code). The longer the chip, the greater the probability that the original data can be recovered. Even if one or more bits in the chip are damaged during transmis- sion, statistical techniques embedded in the radio can recover the original data without the need for retransmission. To an unintended receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most narrowband receivers. Would the information be intercepted while transmitting on air? WLAN features two-fold protection in security. On the hardware side, as with Direct Sequence Spread Spectrum technology, it has the inherent security fea- ture of scrambling. On the software side, the WLAN series offers the encryp- tion function (WEP) to enhance security and access control. Users can set it up depending upon their needs. Can Instant Wireless' products support file and printer sharing? Instant Wireless"' products perform the same function as LAN products. Therefore, Instant Wireless' products can work with Netware, Windows NT/2000, or other LAN operating systems to support printer or file sharing. What is WEP? WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40 bit shared key algorithm, as described in the IEEE 802.11 standard. What is a MAC Address? The Media Access Control (MAC) address is a unique number assigned by the manufacturer to any Ethernet networking device, such as a network adapter, that allows the network to identify it at the hardware level. For all practical pur- poses. this number is usually permanent. Unlike IP addresses, which can change every time a computer logs on to the network, the MAC address of a device stays the same, making it a valuable identifier for the network. 30 31 EFTA00578377 Instant Wireless TM Series Wireless Network Access Point Appendix B: Setting Up the TCP/IP Protocol Setting Up TCP'IP in Windows Before a computer can communicate with the Access Point, it must be config- ured with the TCP/IP protocol.
