Antenna

The WYR-G54 has one internal omnidirectional antenna. The transmission of wireless signals is isotropic, meaning that the waves are emitted much like the sun distributes light in every direction. However, connection problems can occasionally be remedied by simply adjusting the position of the 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 WYR-G54 to the right. This will expose the MC Connector. Attaching the antenna is simple, just insert the antennas MC Connector into the WYR-G54s MC Connector 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.

Setup Wizard - Security

Security Setup

Wireless Security Setup

Encrypting your wireless data is important to prevent other devices from being able to monitor your wireless data transmissions. There are two options available TKIP or WEP. One or the other may be selected, or you can choose not to enable security and allow open movement of trafc.
TKIP - check with your client adapter vendors to make sure that ALL of your wireless adapters support this method of WPA encryption. WEP - while most wireless adapters support WEP, it has been shown not to be as robust as TKIP, though it is considered adequate for home use. Disabled - when security is disabled, clicking Continue will return you to the Home screen where other congurations can be made or you can Log Out of the access point and begin using your AirStation normally.

Wireless Settings

WEP Setup
- If WEP is chosen as the encryption type, you need only to enter in an encryption key. Note that depending on the type (ASCII vs. HEX), the length of the key will vary depending on the numbers of bits in use.

TKIP Setup

- If TKIP is chosen as the encryption type, you need only to enter a pre-shared key. Note that depending on the type (ASCII vs. HEX), the limitations of the key length will vary. The rekey interval can be left at its default settings unless advanced conguration is needed.
Security Setup Completion
- Once the encryption key has been successfully added, the AirStation will save the key and restart. At this point, the key will need to be entered into any device connecting wirelessly to pass data through the AirStation. If problems are encountered connecting wirelessly with the encryption key, please use a wired connection to attempt conguration or reset the AirStation with its reset button on the rear face.

LAN Settings

To add users to the access tables, they must have previously connected to the AirStation. Select the clients you wish to limit access to and click Apply. Clients can be removed from the table at a later time if needed. Note: Always click Apply to save your changed settings to the AirStation.

Advanced Settings

WAN Port Settings WAN MAC Address - The WAN Ports MAC Address occassionaly is required to be set to a value other than the default. Only change the value if required by your ISP. Login Method - There are several ways of creating a connection to your broadband provider. In most cases, your ISP will use a Direct Connection, however, in some cases PPPoE or IP Unnumbered is used which will require the entering of information provided by your ISP. If you are unsure of which to use, please contact your ISP.

WAN Port Settings

Direct Connection Options
Direct Connection Options - IP Address and DNS Server Address settings may have been provided by your ISP. If this is the case, they should be entered here, otherwise leave the default settings in place to acquire these settings automatically via DHCP.

PPPoE Client Options

PPPoE Client Options - If you are using PPPoE for your broadband connection, your ISP should have given some custom information to enter. If you do not have this information, it will be necessary to collect it from them. The connection can be set to the following types: Connection on Demand - The connection is opened when activity is detected and terminated after a set period of inactivity (20 minutes by default). Manual Connection - The connection must be manually started and stopped. Continuous Connection - The AirStation will keep the connection alive indenitely. PPPoE Multisession - The AirStation supports PPPoE Multisession as well. If your class of broadband requires this information, hit the Multisession to enter the information in a separate window. Make sure to hit Apply when the data entry is complete. The MTU value (578-1492) should only be changed if specically instructed to by your ISP.

Address Translation

Address Translation Bridging PPPoE and VPN Pass-Through
Address Translation (NAT)
PPPoE Bridging - If a device on the LAN Ports is capable of managing PPPoE client communications, enabling this option will allow the device the necessary direct, pass-through access to the WAN port. VPN Pass-Through - If you have client devices that will need to create VPN tunnels with IPSec or PPTP, this option should not be disabled. It is enabled by default.
In some situations, it is benDemilitarized ecial to have a client network Zone Client device designated as a catchall, with all ports opened to enable better functionality with services like messaging or gaming. Using a Demilitarized zone will allow one local network device to be exposed to the Internet for use of a specialpurpose service such as Internet gaming or videoconferencing. DMZ hosting forwards all the ports at the same time to the selected device. Packet Filtering is more secure as it only opens the ports designated to be opened, while a Demiliatrarized Zone will open every port of a designated device.
Network Address Translation
Address Translation by Service
NAT by Service and Device
Some of the common services that address translation is necessary to use with are offered precongured. By selecting a service, most elds will be autolled to make setup easier, however if you are using a service different from what is offered or with different congurations, you can a a new service by clicking the Add New Server button. Be sure to accurately enter the appropriate settings and clicking the appropriate network device from the Local Client Server dropdown list while it is connected to the AirStation.

Packet Filtering

The AirStation supports the TCP and UDP protocols for Network Address Translation. Packet Filtering Packet Filtering congures advanced public services on your local network, such as web servers, FTP servers, email servers, gaming servers or other specialized Internet services that require delivery of specic requests through the router to the appropriate local network device for delivering specic appication requests.
When unique requests for a particular response are delivered to your router via the Internet, the router will forward those requests to the designated local network device for appropriate response. Because when DHCP is in use, IP Addresses could change for a client device over time, it is best practice to assign local network devices that have packet ltering rules assigned to them to use a xed IP Address to prevent failures due to a change in IP Address that the packet lter does not acknowledge.

Intrusion Detector

Intrusion Detector There are three levels for Intrusion Detector to function at. High: Recommended for Internet bandwidth of 2 Mbps or higher. Medium: Recommended for Internet bandwidth between 1 and 2 Mbps bandwidth. Low: Recommended for bandwidth under 1 Mbps. Because your AirStation uses an SPI Firewall, it is important to temper your security level to your broadband connection speed.
Even at the Low setting, your AirStation will provide an ample amount of security for your network.

UPnP Service

Enabling the UPnP Service enables other UPnP enable devices to easily regonize and congure one another according to the developing UPnP standard. Note: If IP-Unnumbered conguration is in use for DSL connections, UPnP should not be enabled to prevent conicts.

System Information

System Information Firmware Version - Displays the current rmware version running on the AirStation. DHCP - Displays whether the AirStation is operating as a DHCP client on its WAN port. The amount of time left on the DHCP lease is shown as well as the ability to have the AirStation release and renew its current IP conguration on the WAN port. LAN/WAN -Various details about the IP conguration and MAC Addressing information is shown about the LAN and WAN ports. The connection method of the WAN port and the status of that connection is displayed as well.

Basic Settings

Basic Settings The AirStation is congured with an administrator account named root. It can not be changed to another name. The default password of the AirStation is blank (i.e. no text). This value can and should be changed. The new password should be 8 alphanumeric characters long and can include an underscore character ( _ ). The password is case sensitive. If the password is forgotten, it will be necessary to reset the AirStation via the Reset button on the rear face, which will cause all other congurations to restore to factory defaults.

Client Monitor

Client Monitor Client Monitor allows you to view the currently connected clients. While DHCP clients are shown automatically, it is necessary to manually add clients with xed IP Addresses in order for them to appear in Client Monitor By clicking Detailed PC Settings a new window will appear where you can manually x what IP Address is assigned to DHCP clients. This is useful for managing multiple DHCP clients that will have the same IP Address at each connection.

Diagnostics

Diagnostics The Diagnostics screen allows you to perform some basic connectivity troubleshooting. A local or external IP Address can be entered and checked for connectivity by clicking Ping.
The results from the Ping will show whether external or internal connectivity is present to a client device or remote resource from the router. This is useful to conrm that a connectivity problem exists on a client rather than on the router. Also, to check name resolution via DNS, a domain name can be entered. The results will show the IP Address of the domain name if successful. A failure could indicate an error in the DNS Server entries for the router that should be conrmed with your ISP.

Log Information

You can specify the types of events Information that are recorded into the log for later viewing. Internet Connection - Logs successes for failures when connecting externally via the WAN port. Access Restrictions - Logs successes or failures of clients connecting via the LAN port. Intrustion Detector - Logs possible malicious attacks that are blocked by the Intrusion Detector rewall Note: To add value to the recorded logs, be sure to set your time zone accurately.

Save or Restore Settings

Save Settings - Your current settings can be saved as an image le that can be restored to your AirStation at a later date. This is also useful for easily setting up multiple AirStations with identical settings. Restore Settings - If a settings le was previously created, it can be quickly restored to the AirStation. Note that the settings le will overwrite all current settings when it is restored.

Restore Defaults

Restart or Restore Settings
Restart Occasionally it may be necessary to restart your AirStation. Often the rst start in troubleshooting a problem is to simply restart the device. Restore Factory Defaults To return the AirStation back to its original out of the box conguration, click the Restore button. All changes will be lost, so it is best practice to create a saved settings le in advance.
Buffalo Technology USA regularly provides rmware updates to enhance performance, provide additional features and to x bugs. Please check our website listed below for udpates. Firmware updates should be done with a wired connection as opposed to wirelessly. Also, it is best practice to save your current settings to a saved settings le in advance.
