Power down the cable or DSL modem and the computer which will be used to con gure the AirStation router. 2. Plug the cable or DSLs LAN Ethernet cable into the AirStations WAN port. Initially, you may need to unplug this cable from your computer, hub or other router. 3. Plug the provided Ethernet cable into a LAN port on the AirStation and plug the other end into your computer Ethernet adapters (NIC) port. If you plan to initially con gure the AirStation via a wireless connection, (not recommended), you may skip this step. 4. Power on your cable or DSL modem, wait one full minute, Power on the AirStation router, wait another full minute and then power on the computer which will be used to con gure the AirSta-
tion. If the red DIAG light on the AirStation is lit or ashing after several minutes of being pow-
ered on, please consult Buffalo Technical Support. 9 Standard Settings 3.1 Introduction Con guring the AirStation using a standard web browser requires basic wireless con guration knowledge. Setup includes manual wireless con guration and basic administrative management. 3.2 Setup Preparation Make note of the AirStations wired MAC address (found on the back of the WBR2-G54). It is also recommended you record any other broadband ISP information such as global IP address, subnet mask address, default gateway address, DNS server address and PPPoE parameters. 3.3 Setup Overview Buffalo recommends using a wired connection, meaning your computer is physically connected to the AirStation with a CAT5 straight cable plugged into one of the four LAN ports This type of setup will eliminate possible setup problems due to any issues with the wireless adapter on the computer being used to con gure the AirStation. A Web browser version 4.5 or later can be used to con gure the AirStation. Advanced settings for security, ltering and other features will be explained in later sections. 10 Antenna Installation The WHR2-G54 has two internal antennas. One has a vertical orientation while the other has a horizontal orienta-
tion. This setup is ideal because it allows for proper antenna polarization with both desktop and notebook style wireless adapter antennas. However, it may be necessary to increase your range further by installing an external, higher-gain antenna. External antennas come in all shapes and sizes. Antennas also come with different connectors. The WHR2-G54 has an MC Connector on it. Thus, the antenna must also have an MC connector. To install the antenna, slide the antenna connector door on the back of the WHR2-G54 to the right. This will expose the MC Connector. Attaching the antenna is simple, just insert the antennas MC Connector into the WHR2-G54s MC Con-
nector and rmly push it in until it snaps into place. Once snapped, the antennas connector will swivel with ease. It is important not to push the antenna connector in at an angle. To remove the antenna, pull the antenna connector out. It is important not to pull the antenna connector out at an angle. 11 Standard Settings 3.4 Open the Setup Screen Connect the WBR2-G54 according to the wiring instructions in Section 2.

Users no longer need to worry about choosing the proper security protocols, IP addresses, or ESS-ID's. The intelligence of AOSS determines the most optimal connection and con gures itself in seconds. NOTE: AOSS automatically creates a secure connection between your AOSS Access Point and client. You must have a Buffalo AOSS enabled wireless client device to use the AOSS features of your AOSS Access Point/Router. Con gure your WBR2-G54's internet con-
nection by referring to the instructions in the WBR2-G54's Quick Setup Guide. Once the WBR2-G54 has been con g-
ured, follow the directions to install your wireless client device and its drivers if necessary. Certain wireless client adapt-
ers require client software to con gure them. If your device has a Client Man-
ager, then install it as well. Standalone AOSS Device Client Manager Client Manager Device Software NOTE: If the wireless client adapter is installed on a PC, then the AOSS client manager will need to be installed as well. If your wireless client adapter is a standalone device that does not require a PC, then just power up the device. Standalone Devices: Ethernet Converters and Access Point Bridges Client Manager Devices: CardBus, USB, and PCI Adapters. 21 AOSS Now that the WBR2-G54 and wireless client adapter are installed, you can use AOSS to con gure them. To begin the con guration, press the AOSS button on the back of the WBR2-G54 for 3-5 seconds. The AOSS light will begin to ash when the AOSS mode has been enabled. You can stop pressing the button at this point. NOTE: AOSS mode will stay active for a period of two minutes. This is the time-slot required to initiate the wireless client adapter. The AOSS LED will stop ashing when AOSS mode has stopped or timed out. Refer to your wireless client adapter's AOSS supplement to initiate the wireless client adapter's AOSS mode. It typically takes 10-15 seconds for the AOSS light to stop ashing after the AOSS button has been pressed on the wireless client adapter. Once con guration is complete, the AOSS light will remain steady. Please refer to your wireless client adapter's supplement for the remainder of the setup. 22 Additional AOSS Information:
Only one AOSS wireless client adapter can be con gured to the AOSS router at a time. Thus, the button will need to be repressed for each additional AOSS wireless client adapter that will be connected. It is not necessary to AOSS client devices that have already been con gured via AOSS, unless signi cant changes have been made to the wireless network. Do not attempt to con gure two separate AOSS networks at the same time, as it may cause undesired con gurations. If an undesired client has connected via AOSS, it can be disconnected from within the WBR2-
G54's advanced con guration menus. 23 Click the Top tab and click the Advanced button. Fig ure 4.1.1 Wireless Settings Advanced Settings 4.1 LAN Settings Set up LAN connections. 4.1.1 Wireless Wireless Function - Enable or disable wireless LAN computer communication. ESS-ID (SSID) - Allows ad-
ministrator to alter the ESS-ID of the AirStation. To com-
municate with a speci c AP only, the APs ESS-ID must be entered in the client computer. The client computer looks for the speci c AP (or ESS-ID) for wireless communication. Use up to 32 al pha nu mer ic characters for the ESS-ID (case sensitive). By default the ESS-ID is the LAN Mac address of the AirStation. Note: Roaming - When multiple AirStations have an identical ESS-ID, WEP key (if WEP is used),
(and channel in WDS mode) , client computers may Roam between the AirStations. Wireless Channel - Select the channel used for wireless communication. There are 11 overlap-
ping channels. Channels 1, 6 and 11 are non-overlapping. 24 Advanced Settings If there are multiple APs in close proximity using the same channel, there may be interference. In this case, change to a non-overlapping channel. Privacy Separator - Enable or disable communication between wireless clients. If you choose to use this feature, every wireless client that is associated to the AirStation will not be able to commu-
nicate with any other wireless clients. Note: If this function is used, wired clients can still communicate with wireless clients. BSS (Basic Service Set) Basic Rate Set - The transmission data rates offered by the AirStation. It is recommended to use the Default selection to accomidate 802.11 and 802.11b rate sets. It is NOT recommended to use the All selection, as some devices may not understand all of the rate sets offered by the AirStation. Frame Bursting - This function increases 802.11b communication throughput by transferring pack-
ets more ef ciently. The following conditions affect this function:
The wireless LAN client adapter must support Frame Bursting (and it must be enabled). If the wireless LAN client adapter does not support Frame Bursting, or Frame Bursting is not enabled, then it will operate at non-Frame Bursting speeds. It is recommended to leave Frame Bursting enabled as it can only help throughput, not hurt it. DTIM Period - An access point transmits beacon signals to nearby clients at a preset interval. This parameter sets the beacon transmission interval time (1-255 seconds). Se lec tion of a larger num-
ber may conserve energy for the client computer (when client power management is enabled), but may delay wireless communication. The default value of 1 is recommended. 25 Advanced Settings Wireless output power - Con gure output power of the AirStation. Decrease wireless output power to shrink the wireless communication range. The default setting of 100% is recommended unless decreased range is desired 4.1.2 Wireless LAN Security Broadcast SSID - Enable or Disable the SSID (ESS-ID) from being broadcasted. If denied, the AirStation will not be found unless the speci c AirStations SSID is entered in the client computer manually. Fig ure 4.1.2 Wireless Security Settings Data Encryption - Disable to have no encryption of the wireless data. This will make accessing the AirStation and the network very easy. It is important to note, that without encryption it is easy for strang-
ers to connect to your network, especially if the AirStation is broadcasting its SSID. Select the type of data encryp-
tion:
26 Advanced Settings Disabled - Disable data encryption.
- WEP - Uses WEP encryption. Encryption key should be entered.
- TKIP - Uses TKIP (Temporal Key Integrity Protocol) for data encryption. The encryption key is renewed every Re-key interval when TKIP is selected. WEP - When the WEP (Wired Equivalent Protection) encryption standard is implemented into a wireless network, a WEP key is used between the client and access point to successfully encrypt, transmit and decrypt data. For this reason, the same WEP key must be used for communication between the client and the AirStation. An access point and client may both carry multiple WEP keys. It is necessary for not only the WEP keys to match, but also the WEP keys order. If a wireless client cannot support multiple WEP keys, the AirStations must be con gured to transmit key number 1 for a connection to take place. Examples of WEP key:
64-bit ASCII: 5 digits of alphanumeric characters, ab34Y 128-bit ASCII: 13 digits of alphanumeric characters, 123456abcdef7 Note: ASCII WEP keys are case sensitive. 64-bit HEX: 10 digits, using characters 0-9 and a-f, 00234ABCDE 128-bit HEX: 26 digits, using characters 0-9 and a-f, 20123456789abcdeabcdeabcde TKIP - TKIP (Temporal Key Integrity Protocol) is a WEP expanded encryption technique. TKIP has 27 Advanced Settings greatly improved WEPs weaknesses by rotating secret keys between every packet. TKIP uses WPA-PSK (pre-Shared Key). AES - (Advanced Encryption Standard) is a next generation encryption technique discussed by the IEEE 802.11i committee for WPA2. TKIP improves WEPs weakness, however AES also changes encryption method away from the weaker RC4 style. Throughput decreases 10 to 20 percent when TKIP software encoding is used. On the other hand, AES doesnt decrease performance at all because it uses a hardware co-processor. TKIP Method - The TKIP method speci es whether TKIP is processed via a software algorithm or through a hardware accelerator. The hardware method has a limitation of 12 clients, the software client has a higher limitation of 50 clients. It is recommended to use the hardware method unless more then 50 clients will be using TKIP at any given time. The hardware method results in better wireless performance. Characteristics:
- The Initialization Vector is expanded from 24-bits to 48-bits.
- The Initialization Vector is randomized.
- Uses a different RC4 key for every packet. TIKIP requires an 8 to 63 character passphrase in ASCII or 64 digits hexadecimal key. Example 1: [ airstation -WPA-PSK ]
Example 2: [0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef]
28 Advanced Settings WPA Group Rekey Interval - When TKIP is selected, the encryption key is renewed at this inter-
val. This interval is in seconds; the range of acceptable values is 0-3600. If 0 is entered, the key is never renewed. Note: The lower the rekey interval, the more often a rekey occurs. Setting a low rekey interval may affect performance negatively. IEEE802.1x/EAP authentication (WPA) - Con gure Authentication and WPA Settings. Do not authorize - Do not use any RADIUS Server based authentication. Authorize - Authorized clients access this AirStation via RADIUS Server. Use 802.1x/EAP to authorize every wireless client who wants to access the AirStation by using 802.1x/EAP and a RADIUS Server. The RADIUS server provides login information for every user establishing a more secure system than TKIP or other xed encryption key methods. This also reduces the amount of necessary key maintenance. A RADIUS server is necessary for IEEE802.1x/EAP authentication. Enter [RADIUS Server], {RA-
DIUS Port] and [RADIUS Key] information. RADIUS authentication RADIUS Server - Enter RADIUS server IP address. RADIUS Port - Enter port number for authentication. RADIUS Key - Encryption key between RADIUS Sever and the AirStation. Enter the same key as registered in the server. Use a 1 to 256 character alphanumeric code. 29 Figure 4.1.3 LAN Port Settings Advanced Settings 4.1.3 LAN Port Set the LAN side Ethernet settings. LAN Side IP address - Allows ad min is tra tor to specify a static IP and Subnet Mask for the LAN side of the AirStation. Note: If the AirStations IP address is changed, the con-
guring computers IP must be changed to the same range to continue con guration. If the LAN IP is changed, restart the AirStation. (Section 4.4.10). If the IP address is changed, then the DHCP scope must be changed to match. DHCP Server Function - Allows administrator to enable/disable the DHCP server function for the AirStation LAN side. Select Use to enable and Do not use to disable the function. Once Use is selected, the assigned IP address range can be speci ed. Enter the starting LAN IP address and total number of computers the DHCP server can accomidate. Note: If there is another DHCP server on the network, one either must be disabled or the IP range must be changed to avoid con icts derived from overlapping DHCP scopes. 30 Figure 4.1.4 DHCP Server Settings Advanced Settings 4.1.4 DHCP Server Allows a more advanced con-
