5HARDWARE CONNECTION Note: Before you starting hardware connection, you are advised to find an appropriate location to place the Access Point. Usually, the best place for the Access Point is at the center of your wireless network, with line of straight to all your wireless stations. Also, remember to adjust the antenna; usually the higher the antenna is placed, the better will be the performance. 1. Connect to your local area network: connect a Ethernet cable to one of the Ethernet port (LAN1 or LAN2) of this Wireless Access Point, and the other end to a hub, switch, router, or another wireless access point. 2. Power on the device: connect the included AC power adapter to the Wireless Access Point’s power port and the other end to a wall outlet. Check the LEDs: The Power and LAN # LEDs should be ON. LAN# LED will even blink if there is traffic. The Link/Act LED will be on in static when associated with a station and blink whenever this AP receives data packets in the air. If the Status LED glows after self-test , it means this Wireless Access Point fails on self test. Please ask your dealer for technical support. 3. Configure your PC: Make sure your local PC(s) has wireless network adapter installed.

6ABOUT THE OPERATION MODES This device provides four operational applications with Access Point, Bridge, Client (Ad-hoc) and Client (Infrastructure) modes, which are mutually exclusive. This device is shipped with configuration that is functional right out of the box. If you want to change the settings in order to perform more advanced configuration or even change the mode of operation, you can use the web-based utility provided by the manufacturer as described in the following sections. Access Point Mode When acting as an access point, this device connects all the stations (PC/notebook with wireless network adapter) to a wired network. All stations can have the Internet access if only the Access Point has the Internet connection. See the sample application below. To set the operation mode to Access Point, please go to “Wireless JBasic Settings”, in the “Mode” field click the down arrow b to select AP mode. WDS Repeater Mode Refer to the illustration below. While acting as Bridges, AP1 (with Station 1 being associated to) and AP2 (with Station 2 being associated) can communicate with each other through wireless interface (with WDS). Thus Station 1 can communicate with Station 2 and both Station 1 and Station 2 are able to access the Internet if only AP1 or AP2 has the Internet connection.

7To set the operation mode to Bridge, please go to “Wireless JBasic Settings”, in the “Mode” field click the down arrow b to select AP mode. And go to “Wireless JWDS Settings” to enable WDS. Note: To act as Bridge, both AP1 and AP2 must have WDS enabled and add each other as its WDS Access Point. (e.g. Add AP2’s MAC address to AP1’s “WDS AP List” and vice versa) Client Mode (Infrastructure) If set to Client (Infrastructure) mode, this device can work like a wireless station when it’s connected to a computer so that the computer can send packets from wired end to wireless interface. Refer to the illustration below. This station (AP1 plus the connected computer 1) can associate to another Access Point (AP2), and then can have the Internet access if the other Access Point (AP2) has the Internet connection.

8To set the operation mode to Client (Infrastructure), please go to “Wireless JBasic Settings”, in the “Mode” field click the down arrow b to select Client mode, and then select “Network Type” as “Infrastructure”. Client Mode (Ad-hoc) If set to the Client (Ad-hoc) mode, this device can work like a wireless station when it is connected to a computer so that the computer can send packets from wired end to wireless interface. You can share files and printers between wireless stations (PC and laptop with wireless network adapter installed). See the sample application below. To set the operation mode to Client (Ad-hoc), please go to “Wireless JBasic Settings”, in the “Mode” field click the down arrow b to select Client mode, and then select Network Type as “Ad-hoc”.

9 WDS Bridge Mode The WDS (Wireless Distributed System) function let this access point acts as a wireless LAN access point and repeater at the same time. Users can use this feature to build up a large wireless network in a large space like airports, hotels and schools …etc. This feature is also useful when users want to bridge networks between buildings where it is impossible to deploy network cable connections between these buildings.

System System Uptime The time period since the device was up. Firmware Version The current version of the firmware installed in this device. Wireless Configuration Mode There are four modes supported, Access Point, Client (Ad-hoc and Infrastructure), WDS Bridge and WDS repeater. The default mode is Access Point. If you want to change to bridge mode, please go to Wireless/WDS Setting to enable the WDS function. Band Shows the wireless band. SSID The SSID differentiates one WLAN from another, therefore, all access points and all devices attempting to connect to a specific WLAN must use the same SSID. It is case-sensitive and must not exceed 32 characters. A device will not be permitted to join the BSS unless it can provide the unique SSID. An SSID is also referred to as a network name because essentially it is a name that identifies a wireless network. Channel Number The number of channels supported depends on the region of this Access Point. All stations communicating with the Access Point must use the same channel. Encryption WEP Encryption (Wired Equivalent Privacy) is set to

13Disabled by default. When WEP is enabled, data packet is encrypted before being transmitted. The WEP prevents data packets from being eavesdropped by unrelated people. By using WEP data encryption, there may be a significant degradation of the data throughput on the wireless link. BSSID BSSID displays the ID of current BSS, which uniquely identifies each BSS. In AP mode, this value is the MAC address of this Access Point. Associated Clients Displays the total number of clients associated to this AP. You can have up to 64 clients to associate to this Access Point. TCP/IP Configuration Attain IP Protocol Display the method to get the IP of this AP, which could be obtained by Fixed-IP or DHCP-client.

Any parameter change will cause the device to reboot for the new settings to take effect.  Disable Wireless LAN Interface Check the box to disable the Wireless LAN Interface, by so doing, you won’t be able to

14make wireless connection with this Access Point in the network you are located. In other words, this device will not be visible by any wireless station. Band You can choose one mode of the following you need.  2.4GHz (B): 802.11b supported rate only.  2.4GHz (G): 802.11g supported rate only.  2.4GHz (B+G): 802.11b supported rate and 802.11g supported rate. The default is 2.4GHz (B+G) mode. Mode This Wireless Access Point can support four modes AP, Client, Bridge and Repeater. (Refer to page 7-11 for detailed information) Network Type When in Client mode, you can select between Ad-Hoc and Infrastructure. SSID The SSID differentiates one WLAN from another, therefore, all access points and all devices attempting to connect to a specific WLAN must use the same SSID. It is case-sensitive and must not exceed 32 characters. A device will not be permitted to join the BSS unless it can provide the unique SSID. An SSID is also referred to as a network name because essentially it is a name that identifies a wireless network. Channel Number Allow user to set the channel manually or automatically. If set channel manually, just select the channel you want to specify. If “Auto” is selected, user can set the channel range to have Wireless Access Point automatically survey and choose the channel with best situation for communication. The number of channels supported depends on the region of this Access Point. All stations communicating with the Access Point must use the same channel. Associated Clients Click to show the associated client list. Enable Mac Clone (Single Ethernet Client) If your ISP restricts service to PCs only, use the MAC Clone feature to copy a PC Media Access Control (MAC) address to your router. This procedure will cause the router to appear as a single PC, while allowing online access

15to multiple computers on your network. Apply Changes Press to save the new settings on the screen. Reset Press to discard the data you have entered since last time you press Apply Change. Advanced Settings It is not recommended that settings in this page to be changed unless advanced users want to change to meet their wireless environment for optimal performance Authentication Type To provide a certain level of security, the IEEE 802.11 standard has defined two types of authentication methods, Open System and Shared Key. With Open System authentication, a wireless PC can join any network and receive any messages that are not encrypted. With Shared Key authentication, only those PCs that possess the correct authentication key can join the network. By default, IEEE 802.11 wireless devices operate in an Open System network. Wired Equivalent Privacy (WEP) data encryption is used when the wireless devices are configured to operate in Shared Key authentication mode.

16If the Access Point is using Open System, then the wireless adapter will need to be set to the same authentication mode. Shared Key is used when both the sender and the recipient share a secret key. Select Auto for the network adapter to select the Authentication mode automatically de pending on the Access Point Authentication mode. Fragment Threshold Fragmentation mechanism is used for improving the efficiency when high traffic flows along in the wireless network. If your 802.11g Wireless LAN PC Card often transmit large files in wireless network, you can enter new Fragment Threshold value to split the packet. The value can be set from 256 to 2346. The default value is 2346. 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 Access Point, but are not within range of each other. Therefore, they are hidden nodes for each other. When a station starts data transmission with the Access Point, it might not notice that the other 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 Access Point. The collision will most certainly result in a loss of messages for both stations. Thus, the RTS Threshold mechanism provides a solution to prevent data collisions. When you enable RTS Threshold on a suspect “hidden station”, this station and its Access Point will use a Request to Send (RTS). The station will send an RTS to the Access Point, informing that it is going to transmit the data. Upon receipt, the Access Point will respond with a CTS message to all station within its range to notify all other stations to defer transmission. It will also confirm the requestor station that the Access Point has reserved it for the time-frame of the requested transmission. If the “Hidden Node” problem is an issue, please specify the packet size. The RTS mechanism will be activated if the data size exceeds the value you set.. The default value is 2347. Warning: Enabling RTS Threshold will cause redundant network overhead that could negatively affect t

17he throughput performance instead of providing a remedy. This value should remain at its default setting of 2347. Should you encounter inconsistent data flow, only minor modifications of this value are recommended. Beacon Interval Beacon Interval is the amount of time between beacon transmissions. Before a station enters power save mode, the station needs the beacon interval to know when to wake up to receive the beacon (and learn whether there are buffered frames at the access point). Data Rate By default, the unit adaptively selects the highest possible rate for transmission. Select the basic rates to be used among the following options: Auto, 1, 2, 5.5, 11or 54 Mbps. For most networks the default setting is Auto which is the best choice. When Auto is enabled the transmission rate will select the optimal rate. If obstacles or interference are present, the system will automatically fall back to a lower rate. Preamble Type A preamble is a signal used in wireless environment to synchronize the transmitting timing including Synchronization and Start frame delimiter. In a "noisy" network environment, the Preamble Type should be set to Long Preamble. The Short Preamble is intended for applications where minimum overhead and maximum performance is desired. If in a "noisy" network environment, the performance will be decreased. Broadcast SSID Select enabled to allow all the wireless stations to detect the SSID of this Access Point. IAPP IAPP (Inter Access Point Protocol) is designed for the enforcement of unique association throughout a ESS (Extended Service Set) and a secure exchange of station’s security context between current access point (AP) and new AP during handoff period. 802.11g Protection The 802.11g standard includes a protection mechanism to ensure mixed 802.11b and 802.11g operation. If there is no such kind of mechanism exists, the two kinds of standards may mutually interfere and decrease network’s performance. Apply Change Press to save the new settings on the screen. Reset Press to discard the data you have entered since last time you press Apply Change. Security Here you can configure the security of your wireless network. Selecting different method will enable you to have different level of security. Please note that by using any encryption, by which data packet is encrypted before transmission to prevent data packets from being

18eavesdropped by unrelated people, there may be a significant degradation of the data throughput on the wireless link. Encryption: None (Encryption is set to None by default) If Use 802.1x Authentication is selected, the RADIUS Server will proceed to check the 802.1x Authentication. Encryption: WEP If WEP is selected, users will have to Set WEP keys either manually, or select to Use 802.1x Authentication to make the RADIUS server to issue the WEP key dynamically.

19 Set WEP key  Click the Set WEP Keys will prompt you a window to set 64bit or 128bit Encryption.  Select HEX if you are using hexadecimal numbers (0-9, or A-F). Select ASCII if you are using ASCII characters (case-sensitive).  Ten hexadecimal digits or five ASCII characters are needed if 64-bit WEP is used; 26 hexadecimal digits or 13 ASCII characters are needed if 128-bit WEP is used. Encryption: WPA (TKIP) WPA (TKIP): If WPA is selected, users will have to select the Authentication modes between Enterprise (RADIUS) and Personal (Pre-shared Key). Pre-shared Key Pre-Shared-Key serves as a password. Users may key in a 8 to 63 characters string to set the password or leave it blank, in which the 802.1x Authentication will be activated. Make sure the same password is used on client's end. There are two formats for choice to set the Pre-shared key, i.e. Passphrase and Hex. If Hex is selected, users will have to enter a 64 characters string. For easier configuration, the

20Passphrase (at least 8 characters) format is recommended. Group Key Life Time Enter the number of seconds that will elapse before the group key change automatically. The default is 86400 seconds. Enable Pre-Authentication The two most important features beyond WPA to become standardized through 802.11i/WPA2 are: pre-authentication, which enables secure fast roaming without noticeable signal latency. Preauthentication provides a way to establish a PMK security association before a client associates. The advantage is that the client reduces the time that it's disconnected to the network. Authentication RADIUS Server Port: Enter the RADIUS Server’s port number provided by your ISP. The default is 1812. IP Address: Enter the RADIUS Server’s IP Address provided by your ISP. Password: Enter the password that the AP shares with the RADIUS Server. Apply Change Press to save the new settings on the screen.
