This Access Point will allow you to network wirelessly better than ever. How does the Access Point do all of this? An access point allows for greater range and mobility within your wireless network while also allowing you to connect the wireless network to a wired environment. Being a dual-
band access point, not only does the Access Point bring you these benefits, it also allows three wireless standards, 802.11a, 802.11b and 802.11g, to communicate with each other. This means that PCs with different wireless standards can communicate with each other and with a wired network. But what does all of this mean?
Networks are useful tools for sharing computer resources. You can access one printer from different computers and access data located on another computer's hard drive. Networks are even used for playing multiplayer video games. So, networks are not only useful in homes and offices, they can also be fun. PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is why the network is called "wired". PCs equipped with wireless cards and adapters can communicate without cumbersome cables. By sharing the same wireless settings, within their transmission radius, they form a wireless network. This is sometimes called a WLAN, or Wired Local Area Network. The Access Point bridges wireless networks of both 802.11g and 802.11b standards and wired networks. Use the instructions in this Guide to help you connect the Access Point, set it up, and configure it to bridge your different networks. These instructions should be all you need to get the most out of the Access Point. network: a series of computers or devices connected together 802.11a: an IEEE wireless networking standard that specifies a maximum data transfer rate of 54Mbps and an operating frequency of 5GHz. 802.11b: a wireless networking standard that specifies a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz. 802.11g: a 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. ethernet: network protocol that specifies how data is placed on and retrieved from a common transmission medium lan (local area network): the computers and networking products that make up your local network adapter: a device that adds network functionality to your PC Chapter 1: Introduction Welcome 1 Dual-Band Wireless A + G Access Point Whats in this Guide?

3 Dual-Band Wireless A + G Access Point Chapter 2: Planning your Wireless Network Network Topology A wireless network is a group of computers, each equipped with one wireless adapter. Computers in a wireless network must be configured to share the same radio channel. Several PCs equipped with wireless cards or adapters can communicate with one another to form an ad-hoc network. Linksys wireless adapters also provide users access to a wired network when using an access point, such as the Dual-Band Wireless A + G Access Point, or wireless router. An integrated wireless and wired network is called an infrastructure network. Each wireless PC in an infrastructure network can talk to any computer in a wired network infrastructure via the access point or wireless router. ad-hoc: a group of wireless devices communicating directly with each other (peer-
to-peer) without the use of an access point. infrastructure: a wireless network that is bridged to a wired network via an access point. An infrastructure configuration extends the accessibility of a wireless PC to a wired network, and may double the effective wireless transmission range for two wireless adapter PCs. Since an access point is able to forward data within a network, the effective transmission range in an infrastructure network may be doubled. Roaming Infrastructure mode also supports roaming capabilities for mobile users. Roaming means that you can move your wireless PC within your network and the access points will pick up the wireless PC's signal, providing that they both share the same channel and SSID. Before enabling you consider roaming, choose a feasible radio channel and optimum access point position. Proper access point positioning combined with a clear radio signal will greatly enhance performance. roaming: the ability to take a wireless device from one access point's range to another without losing the connection. ssid: your wireless network's name Chapter 2: Planning your Wireless Network Network Topology 4

Chapter 6: Configuring the Dual-Band Wireless A + G Access Point The Wireless Tab - Basic Wireless Settings 21 Dual-Band Wireless A + G Access Point The Wireless Tab - Wireless Security Wireless Security The Wireless Security settings configure the security of your wireless network. There are three wireless security mode options supported by the Access Point: WEP, Pre-Shared Key, and Pre-Shared Key + RADIUS. (WEP stands for Wired Equivalent Privacy, Pre-Shared Key is a security standard stronger than WEP encryption, and RADIUS stands for Remote Authentication Dial-In User Service.) For detailed instructions on configuring wireless security for the Access Point, turn to Appendix B: Wireless Security. WEP. WEP is a basic encryption method, which is not as secure as Pre-Shared Key. To use WEP, select a Default Transmit Key (choose which Key to use), and a level of WEP encryption, 40/ 64 bits, 128 bits, or 152 bits. Then either generate a WEP key automatically using the Passphrase or enter the WEP key manually. Pre-Shared Key. Pre-Shared Key gives you two encryption methods, TKIP and AES, with dynamic encryption keys. Select the type of algorithm, TKIP or AES. Enter a Pre-Shared Key Shared Key of 8-32 characters. Then enter a Group Key Renewal period, which instructs the Access Point how often it should change the encryption keys.

Dual-Band Wireless A + G Access Point The Wireless Tab - Advanced Wireless Settings This screen contains the advanced wireless settings. In most cases, these settings do not need to be changed. Wireless-A Settings Authentication Type. The default is set to Open System (Default) authentication, when the sender and the recipient do NOT use a WEP key for authentication. With Shared Key authentication, the sender and recipient use a WEP key for authentication. Transmission Rate. The rate of data transmission should be set depending on the speed of your wireless network. You can select from a range of transmission speeds, or you can select Auto (Default) to have the Access Point automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed between the Access Point and a wireless client. The default value is Auto (Default). Transmission Power. (Transmit Power Control (TPC)) The greater the transmission power used, the larger the area a wireless network covers. To minimize the likelihood of eavesdropping by unauthorized wireless users, do not use more transmission power than necessary to cover the range needed by your wireless network. Try using the Access Point at different levels of transmission power, and determine how much power is needed to reach the wireless client, such as a PC or access point, that is farthest from the Access Point. Then select the appropriate level, Full (Default), Half, Quarter, Eighth, or Min, from the drop-down menu. The default is Full (Default). Figure 6-9: Advanced Wireless Frame Burst Mode. Enabling this option should provide your network with greater performance, depending on the manufacturer of your wireless products. If you are not sure how to use this option, keep the default, Enabled
(Default). beacon interval: data transmitted on your wireless network that keeps the network synchronized. Beacon Interval. The default value is 100. The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Access Point to synchronize the wireless network. packet: a unit of data sent over a network 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 messages. When the Access Point has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast messages. The default value is 1. Fragmentation Threshold. This value specifies the maximum size for a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor reduction of the default value is recommended. In most cases, it should remain at its default value of 2346. dtim: a message included in data packets that can increase wireless efficiency. fragmentation: breaking a packet into smaller units when transmitting over a network medium that cannot support the original size of the packet. Chapter 6: Configuring the Dual-Band Wireless A + G Access Point The Wireless Tab - Advanced Wireless Settings 25 Dual-Band Wireless A + G Access Point RTS Threshold. Should you encounter inconsistent data flow, only minor reduction of the default value, 2346, is recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be enabled. The Access Point sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send
(CTS) frame to acknowledge the right to begin transmission. The RTS Threshold value should remain at its default value of 2346. Wireless-G Settings Authentication Type. The default is set to Open System (Default) authentication, when the sender and the recipient do NOT use a WEP key for authentication. With Shared Key authentication, the sender and recipient use a WEP key for authentication. Basic Rate. The Basic Rate setting is not actually one rate of transmission but a series of rates at which the Access Point can transmit. The Access Point will advertise its Basic Rate to the other wireless devices in your network, so they know which rates will be used. The Access Point will also advertise that it will automatically select the best rate for transmission. The default setting is Default, when the Access Point can transmit at all standard wireless rates (1-2Mbps, 5.5Mbps, 11Mbps, 18Mbps, and 24Mbps). Other options are 1-2Mbps, for use with older wireless technology, and All, when the Access Point can transmit at all wireless rates. The Basic Rate is not the actual rate of data transmission. If you want to specify the Access Points rate of data transmission, configure the Transmission Rate setting. Transmission Rate. The rate of data transmission should be set depending on the speed of your wireless network. You can select from a range of transmission speeds, or you can select Auto (Default) to have the Access Point automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed between the Access Point and a wireless client. The default value is Auto (Default). Transmission Power.

Then select the appropriate level, Full (Default), Half, Quarter, Eighth, or Min, from the drop-down menu. The default is Full (Default). CTS Protection Mode. CTS (Clear-To-Send) Protection Mode should be set to Auto (Default). The Access Point will automatically use CTS Protection Mode when your Wireless-G products are experiencing severe problems and are not able to transmit to the Access Point in an environment with heavy 802.11b traffic. This function boosts the Access Points ability to catch all Wireless-G transmissions but will severely decrease performance. If you do not want to use CTS Protection Mode at all, select Disabled. rts (request to send): a networking method of coordinating large packets through the RTS Threshold setting. cts (clear to send): a signal sent by a wireless device, signifying that it is ready to receive data.

Band Wireless A + G Access Point. Read the description below to solve your problems. If you can't find an answer here, check the Linksys website 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 network?
This will depend on whether or not the application is designed to be used over a network. Consult the applications user guide to determine if it supports operation 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 network). Refer to the games user guide for more information. What IEEE 802.11b features are supported?
The product supports the following IEEE 802.11 functions:
CSMA/CA 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 applicable at a departmental scale for a branch or SOHO operation. What is Infrastructure?
An integrated wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for wireless access to a central database, or wireless application for mobile workers. Appendix A: Troubleshooting Frequently Asked Questions 32 Dual-Band Wireless A + G Access Point What is Roaming?
Roaming is the ability of a portable computer user to communicate continuously 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 dedicated 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 users end node undertakes 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 nodes RF transmitter regularly checks the system 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 acknowledgment from its original Access Point, it undertakes a new search. Upon finding a new Access Point, it then re-registers, and the communication process continues. 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 developed by the military for use in reliable, secure, mission-critical communications 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). Appendix A: Troubleshooting Frequently Asked Questions 33 Dual-Band Wireless A + G Access Point 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 transmission, 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 feature of scrambling. On the software side, the WLAN series offers the encryption function (WEP) to enhance security and access control. Users can set it up depending upon their needs. Can Linksys Wireless products support file and printer sharing?
Linksys Wireless products perform the same function as LAN products. Therefore, Linksys 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 purposes, 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. How do I avoid interference?
Using multiple Access Points on the same channel and in close proximity to one another will generate interference. When employing multiple Access Points, be sure to operate each one on a different channel
(frequency). How do I reset the Access Point?
Press the Reset button on the back of the Access Point for about ten seconds. This will reset the unit to its default settings. Appendix A: Troubleshooting Frequently Asked Questions 34 Dual-Band Wireless A + G Access Point How do I resolve issues with signal loss?
There is no way to know the exact range of your wireless network without testing. Every obstacle placed between an Access Point and wireless PC will create signal loss. Leaded glass, metal, concrete floors, water and walls will inhibit the signal and reduce range. Start with your Access Point and your wireless PC in the same room and move it away in small increments to determine the maximum range in your environment. You may also try using different channels, as this may eliminate interference affecting only one channel. Also, due to FCC regulations, more power may be transmitted, using 802.11a, on channels 52, 56, 60 and 64, than on the lower channels. Lastly, check the Advanced tab of the Web-Based Utility and make sure that FULL is selected in the Transmission Rate field. Does the Access Point function as a firewall?
No. The Access Point is only a bridge from wired Ethernet to wireless clients. I have excellent signal strength, but I cannot see my network. WEP is probably enabled on the Access Point, but not on your wireless adapter (or vice versa). Verify that the same WEP Keys and levels (64 or 128) are being used on all nodes on your wireless network. What is the maximum number of users the Access Point facilitates?
No more than 65, but this depends on the volume of data and may be less if many users create a large amount of network traffic. How many channels/frequencies are available with the Access Point?
Using 802.11b or draft 802.11g, there are eleven available channels, ranging from 1 to 11. Appendix A: Troubleshooting Frequently Asked Questions 35 Dual-Band Wireless A + G Access Point Appendix B: Wireless Security Linksys wants to make wireless networking as safe and easy for you as possible. The current generation of Linksys products provide several network security features, but they require specific action on your part for implementation. So, keep the following in mind whenever you are setting up or using your wireless network. Security Precautions The following is a complete list of security precautions to take (as shown in this User Guide) (at least steps 1 through 5 should be followed):
1. Change the default SSID. 2. Disable SSID Broadcast. 3. Change the default password for the Administrator account. 4. Enable MAC Address Filtering. 5. Change the SSID periodically. 6. Use the highest encryption algorithm possible. Use WPA if it is available. Please note that this may reduce your network performance. 7. Change the WEP encryption keys periodically. To ensure network security, steps one through five should be followed, at least. Security Threats Facing Wireless Networks Wireless networks are easy to find. Hackers know that in order to join a wireless network, wireless networking products first listen for beacon messages. These messages can be easily decrypted and contain much of the networks information, such as the networks SSID (Service Set Identifier). Here are the steps you can take:
Change the administrators password regularly. With every wireless networking device you use, keep in mind that network settings (SSID, WEP keys, etc.) are stored in its firmware. Your network administrator is the only person who can change network settings. If a hacker gets a hold of the administrators password, he, too, can change those settings. So, make it harder for a hacker to get that information. Change the administrators password regularly. Appendix B: Wireless Security Security Precautions Note: Some of these security features are available only through the network router or access point. Refer to the router or access points documentation for more information. 36 Dual-Band Wireless A + G Access Point SSID. There are several things to keep in mind about the SSID:
1. Disable Broadcast 2. Make it unique 3. Change it often Most wireless networking devices will give you the option of broadcasting the SSID. While this option may be more convenient, it allows anyone to log into your wireless network. This includes hackers. So, dont broadcast the SSID. Wireless networking products come with a default SSID set by the factory. (The Linksys default SSID is linksys.) Hackers know these defaults and can check these against your network. Change your SSID to something unique and not something related to your company or the networking products you use. Change your SSID regularly so that any hackers who have gained access to your wireless network will have to start from the beginning in trying to break in. MAC Addresses. Enable MAC Address filtering. MAC Address filtering will allow you to provide access to only those wireless nodes with certain MAC Addresses. This makes it harder for a hacker to access your network with a random MAC Address. WEP Encryption. Wired Equivalent Privacy (WEP) is often looked upon as a cure-all for wireless security concerns. This is overstating WEPs ability. Again, this can only provide enough security to make a hackers job more difficult. There are several ways that WEP can be maximized:
1. Use the highest level of encryption possible 2. Use Shared Key authentication 3. Change your WEP key regularly WPA. Wi-Fi Protected Access (WPA) is the newest and best available standard in Wi-Fi security. Two modes are available: Pre-Shared Key and RADIUS. Pre-Shared Key gives you a choice of two encryption methods: TKIP
(Temporal Key Integrity Protocol), which utilizes a stronger encryption method and incorporates Message Integrity Code (MIC) to provide protection against hackers, and AES (Advanced Encryption System), which utilizes a symmetric 128-Bit block data encryption. RADIUS (Remote Authentication Dial-In User Service) utilizes a RADIUS server for authentication and the use of dynamic TKIP, AES, or WEP. Important: Always remember that each device in your wireless network MUST use the same encryption method and encryption key or your wireless network will not function properly. Appendix B: Wireless Security Security Threats Facing Wireless Networks 37 Dual-Band Wireless A + G Access Point WPA Pre-Shared Key. If you do not have a RADIUS server, select the type of algorithm, TKIP or AES, enter a password in the Pre-Shared key field of 8-64 characters, and enter a Group Key Renewal period time between 0 and 99,999 seconds, which instructs the Access Point or other device how often it should change the encryption keys. WPA RADIUS. WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Access Point or other device.) First, select the type of WPA algorithm, TKIP or AES. Enter the RADIUS servers IP Address and port number, along with a key shared between the device and the server. Last, enter a Group Key Renewal period, which instructs the device how often it should change the encryption keys. RADIUS. WEP used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Access Point or other device.) First, enter the RADIUS servers IP Address and port number, along with a key shared between the device and the server. Then, select a WEP key and a level of WEP encryption, and either generate a WEP key through the Passphrase or enter the WEP key manually. Implementing encryption may have a negative impact on your networks performance, but if you are transmitting sensitive data over your network, encryption should be used. These security recommendations should help keep your mind at ease while you are enjoying the most flexible and convenient technology Linksys has to offer.
