Configuration The configuration tab contains 5 following items for you to make changes for the FastLinc 810E. General: AP name: In this entry field, you may enter any name. This will enable you to manage your FastLinc 810Es with more ease if you have multiple FastLinc 810Es on the network. -10-
Radio Mode: This item enables you to set the operation mode for the Modems  Wireless LAN Modem (AP): Served as a transparent Media Access Control (MAC) bridge connecting wireless network and the backbone network.  Inter-Building with Repeating (PxP): Connect two or more separated networks with the FastLinc 810E Modem.  Station Adapter – Infrastructure (SAI): Served as a wireless station (infrastructure). Connect the Station Adapter – Infrastructure to a PC with a cross over 10base-T cable, and it is able to access the network via the Access Point (AP).  Station Adapter – Ad-Hoc (SAA): Served as a wireless station (Ad-Hoc). Connecting to a PC with a cross over 10base-T cable, the Ad-Hoc Station Adaptor, along with other Ad-Hoc Station Adapters can establish a small wireless network without an Access Point.  Station Adapter – 802.11 Ad-Hoc (SAA2): Same as SAA except that it operates under 802.11 standards. Note: When setting the operation mode to either PxP or SAA, you need to set all devices in the network to the same channel. ESSID can be ignored. When SAA2 is selected, you need to set all devices with the same ESSID and channel. -11-
IEEE802.11: ESSID: The ESSID is a unique ID given to the FastLinc 810E. Wireless clients associating to the FastLinc 810E must have the same ESSID. The ESSID can have up to 32 characters. Channel: You may select any of the available channels as an operational channel for your FastLinc 810E. RTS Threshold: RTS Threshold is a mechanism implemented to prevent the “Hidden Node” problem. “Hidden Node” is a situation in which two stations are within range of the same FastLinc 810E, but are not within range of each other. Therefore, they are hidden nodes for each other. When a hidden station starts data transmission with the FastLinc 810E, it might not notice that another station is already using the wireless medium. When these two stations send data at the same time, they might collide when arriving simultaneously at the FastLinc 810E. The collision will most certainly result in a loss of messages for both stations. Thus, the RTS Threshold mechanism will provide the solution to prevent data collisions. When the RTS is activated, the station and its FastLinc 810E will use a Request to Send/Clear to Send protocol (RTS/CTS). The station will send an RTS to the FastLinc 810E, informing that it is going to transmit the data. Upon receipt, the FastLinc 810E will respond with a CTS message to all station within its range to notify all other stations to defer transmission. It will also confirm to the requesting station that the FastLinc 810E has reserved the channel for transmission. Fragmentation Threshold: Fragmentation mechanism is used for improving the efficiency when there is high traffic within the wireless network. If you transmit large files in a wireless network, you can enable the Fragmentation Threshold and specify the packet size. The mechanism will split the packet into the packet size you set. -12-
Administration: You may change the default password by entering the new password. Enter the new password in the Confirm Change field to make the new setting take affect. -13-
IP Address: To enable remote access to the FastLinc 810E using Telnet or Web Management, you must assign an IP address to the FastLinc 810E. You may also assign other related Internet addressing options, such as subnet mask or gateway address. Consult your network administrator to obtain an available IP address. WEP: The FastLinc 810E Modem allows you to create up to 4 data encryption keys to secure your data from being eavesdropping by unauthorized wireless user. To activate and set the WEP keys, do the following:  From the WEP encryption item, pull down the menu and it will list three options: Disable – Allows wireless adapters communicate with FastLinc 810Es without any data encryption. WEP40 – Requires wireless stations to use data encryption when communicating with the FastLinc 810E.  When WEP40 is selected, type five alphanumeric characters in the range of “a-z”, “A-Z” and “0-9” (e.g. MyKey) in the WEP Key 1 entry field. Alternatively, you may enter 10 digit hexadecimal values in the range of “A-F” and “0-9”, preceded by the characters “0x” values (e.g. 0x11AA22BB33). You can also enter WEP keys in the Key 2, Key 3 and Key 4 if you wish. WEP will only use 1 Key. You will have to select one WEP key as an active key before enabling use of encryption. -14-
NOTE: The WEP key must be set up exactly the same on the FastLinc 810Es as they are on the wireless client stations. If you use Key 1 on the FastLinc 810E and the value is (e.g. MyCar), the same must be assigned to Key 1 for all client stations. -15-
Upgrade This item is used for uploading the newest firmware of the FastLinc 810E. You may either enter the file name in the entry field or browse the file by clicking the Open File button. For information about the release of the newest firmware, contact Data-Linc Group. Access Control: With the Access Control Table enabled, you can authorize wireless units to access the FastLinc 810E by identifying the MAC address of the wireless devices that are allowed access to transmit data. To create or edit the Access Control Table, do the following: Go to the Access Control tab and select “Enable Access Control”. Note that when you enable the Access Control Table without any MAC address in the table, no access is allowed to communicate with the FastLinc 810E. -16-
