103.1 IntroductionConfi guring the AirStation using a standard web browser requires basic wireless confi guration knowledge. Setup includes manual wireless confi guration and basic administrative management. 3.2 Setup Preparation Make note of the AirStation’s 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 confi gure the AirStation. A Web browser version 4.5 or later can be used to confi gure the AirStation. Advanced settings for security, fi ltering and other features will be explained in later sections. Standard Settings
11The 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 antenna’s MC Connector into the WHR2-G54’s MC Con-nector and fi rmly push it in until it snaps into place. Once snapped, the antenna’s 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.Antenna Installation

21AOSSAOSS (AirStation One-Touch Secure System) is a simple, one-touch setup for connecting wireless clients to an access point while setting up the most secure possible connection. 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 confi 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.◗ Confi 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 confi 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 confi gure them. If your device has a Client Man-ager, then install it as well.■ 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 BridgesClient Manager Devices: CardBus, USB, and PCI Adapters.Standalone AOSS DeviceClient ManagerDevice Client ManagerSoftware
22◗ Now that the WBR2-G54 and wireless client adapter are installed, you can use AOSS to confi gure them.◗ To begin the confi guration, press the AOSS button on the back of the WBR2-G54 for 3-5 seconds. The AOSS light will begin to fl 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 fl 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 fl ashing after the AOSS button has been pressed on the wireless client adapter. Once confi guration is complete, the AOSS light will remain steady. Please refer to your wireless client adapter's supplement for the remainder of the setup.AOSS
23Additional AOSS Information:◗ Only one AOSS wireless client adapter can be confi 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 confi gured via AOSS, unless signifi cant changes have been made to the wireless network.◗ Do not attempt to confi gure two separate AOSS networks at the same time, as it may cause undesired confi gurations.◗ If an undesired client has connected via AOSS, it can be disconnected from within the WBR2-G54's advanced confi guration menus.
24Click the Top tab and click the Advanced button.4.1 LAN Settings Set up LAN connections. 4.1.1 WirelessWireless 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 specifi c AP only, the AP’s ESS-ID must be entered in the client computer. The client computer looks for the specifi 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.Advanced SettingsFig ure 4.1.1WirelessSettings
25If 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 effi 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. Advanced Settings
26Wireless output power - Confi 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 desired4.1.2 Wireless LAN SecurityBroadcast SSID - Enable or Disable the SSID (ESS-ID) from being broadcasted. If denied, the AirStation will not be found unless the specifi c AirStation’s SSID is entered in the client computer manually. 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:Fig ure 4.1.2Wireless Security SettingsAdvanced Settings
27• 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 key’s order. If a wireless client cannot support multiple WEP keys, the AirStations must be confi 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 Advanced Settings
28greatly improved WEP’s 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 WEP’s 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 doesn’t decrease performance at all because it uses a hardware co-processor.TKIP Method - The TKIP method specifi 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]Advanced Settings
29WPA 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) - Confi 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 fi 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. Advanced Settings
