save Save your new configuration. Remember that the “save command” is required every time you make the new configuration. set default Return the factory default settings of the FastLinc 810E except for the IP addresses. A 'save' command is required for changes to take effect. cls* Clear the console screen. exit* Exit the console. ? * or help* Print a help screen. rz* Receive a firmware file by the Zmodem protocol. The console will enter Zmodem receiving mode and then use the "file upload" function of your terminal emulation program to upload a new firmware file (ap.img) to the FastLinc 810E. Upon completion, always remember to type the 'reset' command for running the FastLinc 810E with the new firmware. reset* Issue a reset signal. The FastLinc 810E will be reset if user confirms. 3-2-2 Advanced Settings for Security This section describes the commands to control the security for FastLinc 810E. To prevent unauthorized wireless stations from accessing data transmitted over the network, the FastLinc 810E Modem offers the following levels of security options. - Access Control Table restricts wireless stations to access the FastLinc 810E. - Data Encryption, known as WEP (Wired Equivalency Privacy), encrypts wireless data transmitted via wireless medium. Access Control auth mode | add | del | list| clear The 'auth' command contains sub-commands that allow you to manage the access control (MAC address filter) of the FastLinc 810E. The access control table consists of a list for you to control the accessibility of any wireless stations or repeaters. The sub-commands are listed below: mode open | allow: set the access control mode. The definition of each mode is specified -27-

as follows: • open: open to public (default) • restrict: only allow access of the authorized stations/repeaters in the table (no access is allowed if the list stays empty) add mac_addr: add an address into the access control table del mac_addr |index: delete a MAC address, or index an address from the access control table list [start/end]: display the content of the access control mode and the address list. The optional arguments, start and end, can be affixed to select the range of items to be listed. clear: clear all the addresses in the access control table. WEP Keys wep mode | set | list The 'wep' command contains sub-commands that allow you to manage the data encryption (WEP, wired equivalent privacy) function provided with the FastLinc 810E. The sub-commands are listed as follows: mode disable | wep40: set the access control mode. The following are the definition of each data encryption mode. • none: no encryption (default) • wep40: use 40-bit WEP data encryption -28-

set key1 key_text: set WEP Key#1 as key_text. 10 hexadecimal digits (0-9 or A-F) heading by “0x” or five alphanumeric values (ASCII characters, case-sensitive) are required if 40-bit WEP is used. Example: 0x1122334455, 0x0055AA55AA, abcde, or MyKey. set key2 key_text: set WEP Key#2 as key_text with a same format as WEP Key#1. set key3 key_text: set WEP Key#3 as key_text with a same format as WEP Key#1. set key4 key_text: set WEP Key#2 as key_text with a same format as WEP Key#1. set usekey 1|2|3|4: Select the WEP key to be used for encrypting data transmission. Only one key can be selected at a time. list: Display current WEP settings. Note: Your new WEP settings will take effect after resetting the FastLinc 810E. -29-

Chapter 4 Troubleshooting If you have trouble using the FastLinc 810E Modem, the starting point to troubleshoot the problem with your FastLinc 810E Modem is looking at the LED activity of the FastLinc 810E. The following is “LED Error Table” provided to assist you in diagnosing and solving operational problems. PWR AP Active W-LAN Data LINK Description/Action Steady Green Continuous Green Flash Green Flash Green - Normal operation where flickering indicates interface activity.  No action required. Continuous Green On Off Off - Normal operation that indicates there is no LAN activity.  No action required. Off Off Off Off Off Power failure.  Check the power cord.  Check the power supply. Off Off Off Off Invalid loader firmware or the FastLinc 810E-controller is dead.  Return the unit to the vendor for support. Blink Green - - - Invalid FastLinc 810E firmware.  Upgrade the firmware via the utility or console mode. Blink Green Blink Green - - Wireless LAN initialization failure  Check whether the wireless module has been properly installed. Continuous Green Blink Green - Blink Green - Ethernet initialization failure  Return the device to the vendor for support. -30-

If you are still unable to solve the problem by checking the LED activity, the error may be caused from configuration mismatch, which prevents the FastLinc 810E from establishing a wireless connection with the network. You may check the following to ensure normal operation of the FastLinc 810E.  WEP keys: If data encryption is activated, always remember to set WEP keys exactly the same on the FastLinc 810E as are on the wireless stations.  Access Control: Make sure that the MAC address of your FastLinc 810E is not included in the Access Control table of other wireless devices. -31-

Appendix A Network Configuration The FastLinc Wireless LAN products support the same network configuration options of the legacy Ethernet LANs as defined by IEEE 802 standard committee.

The FastLinc Wireless LAN devices provide access to a wired LAN for wireless workstations. An integrated wireless and wired LAN is called an Infrastructure configuration. A group of wireless LAN PC users and a FastLinc 810E construct a Basic Service Set (BSS). Each wireless-equipped PC in this BSS can talk to any computer in the wired LAN infrastructure via the FastLinc 810E. Infrastructure configuration will extend the accessibility of a wireless station to the wired LAN. Multiple FastLinc 810Es will allow roaming and it will increase the transmission range. The FastLinc 810E is also able to forward data within its BSS. The effective transmission range in an infrastructure LAN is doubled.

Appendix C Glossary FastLinc 810E Modem - An internetworking device that seamlessly connects wired and wireless networks. Ad-Hoc - An Ad-Hoc wireless LAN is a group of computers each with wireless adapters, connected as an independent wireless LAN. Backbone - The core infrastructure of a network. The portion of the network that transports information from one central location to another central location where it is off-loaded onto a local system. Base Station - In mobile telecommunications, a base station is the central radio transmitter/receiver that maintains communications with the mobile radio telephone sets within range. In cellular and personal communications applications, each cell or FastLinc 810Ecell has its own base station; each base station in turn is interconnected with other cells’ base. Bridge - An internetworking function that incorporates the lowest 2 layers of the OSI network protocol model. BSS - Stands for “Basic Service Set,” a FastLinc 810E and all the wireless clients that associated with it. ESS - Stands for “Extended Service Set.” More than one BSS can be configured as an Extended Service Set. Mobile users can roam between BSS in an ESS. Ethernet - A popular local area data communications network, originally developed by Xerox Corp., which accepts transmission from computers and terminals. Ethernet operates on 10 Mbps baseband transmission over shielded coaxial cable or over shielded twisted pair telephone wire. Infrastructure - An integrated wireless and wired LAN is called an Infrastructure configuration. PCMCIA - Personal Computer Memory Card International Association, which develops standards for PC cards, formerly known as PCMCIA cards, are available in three “types” which are about the same length and width as credit cards, but range in thickness from 3.3 mm (Type I) to 5.0 mm (Type II) to 10.5 mm (Type III). These cards can be used for many functions, including memory storage, landline modems and wireless modems. Roaming - A wireless clients around an ESS and get the continuous connection to the Infrastructure network. -36-

RTS Threshold – Transmitters contending for the medium may not hear each other. RTS/CTS mechanism can solve this “ Hidden Node Problem”. If the packet size is smaller than the preset RTS Threshold size, the RTS/CTS mechanism will NOT be enabled. Web Management - Network management by using web browser connecting to the target devices. -37-
