22Appendix A: TroubleshootingFrequently Asked QuestionsWireless-G CompactFlash CardWhat 802.11b features are supported?The product supports the following 802.11b functions: • CSMA/CA plus Acknowledge protocol • Multi-Channel Roaming • Automatic Rate Selection • RTS/CTS feature • Fragmentation • Power ManagementWhat 802.11g features are supported?The product supports the following 802.11g functions: • CSMA/CA plus Acknowledge protocol • OFDM protocol• Multi-Channel Roaming • Automatic Rate Selection • RTS/CTS feature • Fragmentation • Power Management 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 set to the same channel number with 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 user’s 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 node’s 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.
23Appendix A: TroubleshootingFrequently Asked QuestionsWireless-G CompactFlash CardCan Wirelessproducts support printer sharing?Wireless products perform the same function as LAN products. Therefore, Wireless products can work with NetWare, Windows 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 802.11b standard. What is ad-hoc mode?When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to communicate directly with each other. The ad-hoc wireless network will not communicate with any wired network.What is infrastructure mode?When a wireless network is set to infrastructure mode, the wireless network is configured to communicate with a wired network through a wireless access point or router.
24Appendix B: Wireless SecuritySecurity PrecautionsWireless-G CompactFlash CardAppendix B: Wireless SecurityLinksys 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 PrecautionsThe 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 network’s information, such as the network’s SSID (Service Set Identifier). Here are the steps you can take:Change the administrator’s 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 administrator’s password, he, too, can change those settings. So, make it harder for a hacker to get that information. Change the administrator’s password regularly.Note: Some of these security features are available only through the network router or access point. Refer to the router or access point’s documentation for more information.
25Appendix B: Wireless SecuritySecurity Threats Facing Wireless NetworksWireless-G CompactFlash CardSSID. 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, don’t 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 WEP’s ability. Again, this can only provide enough security to make a hacker’s job more difficult.There are several ways that WEP can be maximized:1. Use the highest level of encryption possible 2. Use “Shared Key” authentication3. 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.
26Appendix B: Wireless SecuritySecurity Threats Facing Wireless NetworksWireless-G CompactFlash CardWPA 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 Router 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 Router or other device.) First, select the type of WPA algorithm, TKIP or AES. Enter the RADIUS server’s 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 Router or other device.) First, enter the RADIUS server’s 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 network’s 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.
