Congratulations on the purchase of your new Wireless Router. The Wireless Router is a multi-

function device providing the following services:

Shared Broadband Internet Access for all LAN users. 4-Port Switching Hub for 10BaseT or 100BaseT connections. Wireless Access Point for 802.11b and 802.11g Wireless Stations. Wireless Router Features The Wireless Router incorporates many advanced features, carefully designed to provide sophisticated functions while being easy to use. Internet Access Features Shared Internet Access. All users on the LAN or WLAN can access the Internet through the Wireless Router, using only a single external IP Address. The local (invalid) IP Addresses are hidden from external sources. This process is called NAT (Network Ad-

dress Translation). DSL & Cable Modem Support. The Wireless Router has a 10/100BaseT Ethernet port for connecting a DSL or Cable Modem. All popular DSL and Cable Modems are supported. SingTel RAS and Big Pond (Australia) login support is also included. PPPoE, and PPTP. The Internet (WAN port) connection supports PPPoE (PPP over Ethernet), PPTP (Peer-to-Peer Tunneling Protocol), as well as "Direct Connection" type services. Unnumbered IP with PPPoE is also supported. Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the Wireless Router supports both Dynamic IP Address (IP Address is allocated on connection) and Fixed IP Address. 2 Model No.: WR254 Introduction Advanced Internet Functions Communication Applications. Support for Internet communication applications, such as interactive Games, Telephony, and Conferencing applications, which are often difficult to use when behind a Firewall, is included. Special Internet Applications. Applications which use non-standard connections or port numbers are normally blocked by the Firewall. The ability to define and allow such applications is provided, to enable such applications to be used normally. Virtual Servers. This feature allows Internet users to access Internet servers on your LAN. The required setup is quick and easy. DDNS Support. DDNS (Dynamic DNS) allows Internet users to connect to Virtual Servers on your LAN using a domain name, even if your IP address is not fixed. Multi-DMZ. For each WAN (Internet) IP address allocated to you, one (1) PC on your local LAN can be configured to allow unrestricted 2-way communication with Servers or individual users on the Internet. This provides the ability to run programs which are in-

compatible with Firewalls. URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users. Access Control. Using the Access Control feature, you can assign LAN users to differ-

Internet Access Log. See which Internet connections have been made. ent groups, and determine which Internet services are available to each group. VPN Pass through Support. PCs with VPN (Virtual Private Networking) software using PPTP, L2TP and IPSec are transparently supported - no configuration is required. Wireless Features Standards Compliant. The Wireless Router complies with the IEEE802.11g (DSSS) specifications for Wireless LANs. Supports both 802.11b and 802.11g Wireless Stations. The 802.11g standard provides for backward compatibility with the 802.11b standard, so both 802.11b and 802.11g Wireless stations can be used simultaneously. Speeds to 54Mbps. All speeds up to the 802.11g maximum of 54Mbps are supported. WEP support. Support for WEP (Wired Equivalent Privacy) is included. Key sizes of 64 Bit and 128 Bit are supported. Wireless MAC Access Control. The Wireless Access Control feature can check the the MAC address (hardware address) of Wireless stations to ensure that only trusted Wireless Stations can access your LAN. Simple Configuration. If the default settings are unsuitable, they can be changed quickly and easily. LAN Features 4-Port Switching Hub. The Wireless Router incorporates a 4-port 10/100BaseT switching hub, making it easy to create or extend your LAN. DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP address to PCs and other devices upon request. The Wireless Router can act as a DHCP Server for devices on your local LAN and WLAN. Multi Segment LAN Support. LANs containing one or more segments are supported, via the Wireless Router's RIP (Routing Information Protocol) support and built-in static routing table. 3 Model No: WR254 Configuration & Management Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configu-

ration. Configuration File Upload/Download. Save (download) the configuration data from the Wireless Router to your PC, and restore (upload) a previously-saved configuration file to the Wireless Router. Remote Management. The Wireless Router can be managed from any PC on your LAN. And, if the Internet connection exists, it can also (optionally) be configured via the Internet. Network Diagnostics. You can use the Wireless Router to perform a lookup. Ping or DNS UPnP Support. UPnP (Universal Plug and Play) allows automatic discovery and configuration of the Wireless Router. UPnP is by supported by Windows ME, XP, or later. Security Features Password - protected Configuration . Optional password protection is provided to prevent unauthorized users from modifying the configuration data and settings. Wireless LAN Security . WEP (Wired Equivalent Privacy) is supported, as well as Wireless access control to prevent unknown wireless stations from accessing your LAN. NAT Protection. An intrinsic side effect of NAT (Network Address Translation) technology is that by allowing all LAN users to share a single IP address, the location and even the existence of each PC is hidden. From the external viewpoint, there is no network, only a single device - the Wireless Router. Stateful Inspection Firewall. All incoming data packets are monitored and all incom-

ing server requests are filtered, thus protecting your network from malicious attacks from external sources. Protection against DoS attacks. DoS (Denial of Service) attacks can flood your Internet connection with invalid packets and connection requests, using so much band-

width and so many resources that Internet access becomes unavailable. The Wireless Router incorporates protection against DoS attacks. Package Contents The following items should be included:

To use the Wireless Access Point in the Wireless Router, each Wireless Station must have compatible settings, as follows:

Mode SSID (ESSID) WEP The mode must be set to Infrastructure. This must match the value used on the Wireless Router. The default value is Untitled Note! The SSID is case sensitive. By default, WEP on the Wireless Router is disabled. If WEP remains disabled on the Wireless Router, all stations must have WEP disabled. If WEP is enabled on the Wireless Router, each station must use the same settings as the Wireless Router. Note:

By default, the Wireless Router will allow both 802.11b and 802.11g connections. 44 Model No.: WR254 Appendix A Troubleshooting This Appendix covers the most likely problems and their solutions. Overview This chapter covers some common problems that may be encountered while using the Wire-

less Router and some possible solutions to them. If you follow the suggested steps and the Wireless Router still does not function properly, contact your dealer for further advice. General Problems Problem 1:

Solution 1:

Can't connect to the Wireless Router to configure it. Check the following:

The Wireless Router is properly installed, LAN connections are OK, and it is powered ON. Ensure that your PC and the Wireless Router are on the same network segment. (If you don't have a router, this must be the case.) If your PC is set to "Obtain an IP Address automatically" (DHCP client), restart it. If your PC uses a Fixed (Static) IP address, ensure that it is using an IP Address within the range 192.168.1.1 to 192.168.1.253 and thus com-

patible with the Wireless Router's default IP Address of 192.168.1.254. Also, the Network Mask should be set to 255.255.255.0 to match the Wireless Router. In Windows, you can check these settings by using Control Panel-

Network to check the Properties for the TCP/IP protocol. Internet Access Problem 1: When I enter a URL or IP address I get a time out error. Solution 1:

A number of things could be causing this. Try the following troubleshoot-

ing steps. Check if other PCs work. If they do, ensure that your PCs IP settings are correct. If using a Fixed (Static) IP Address, check the Network Mask, Default gateway and DNS as well as the IP Address. If the PCs are configured correctly, but still not working, check the Wireless Router. Ensure that it is connected and ON. Connect to it and check its settings. (If you can't connect to it, check the LAN and power connections.) If the Wireless Router is configured correctly, check your Internet connection (DSL/Cable modem etc) to see that it is working correctly. Some applications do not run properly when using the Wireless Router. Problem 2:

Model No: WR254 Solution 2:

The Wireless Router processes the data passing through it, so it is not transparent. Use the Special Applications feature to allow the use of Internet applica-

tions which do not function correctly. If this does solve the problem you can use the DMZ function. This should work with almost every application, but:

Only one (1) PC can use this feature. It is a security risk, since the firewall is disabled. Wireless Access Problem 1: My PC can't locate the Wireless Access Point. Solution 1:

Check the following. Your PC is set to Infrastructure Mode) Infrastructure Mode . (Access Points are always in The SSID on your PC and the Wireless Access Point are the same. Remember that the SSID is case-sensitive. So, for example "Work-

group" does NOT match "workgroup". Both your PC and the Wireless Router must have the same setting for WEP. The default setting for the Wireless Router is disabled, so your wireless station should also have WEP disabled. If WEP is enabled on the Wireless Router, your PC must have WEP enabled, and the key must match. If the Wireless Router's Wireless screen is set to Allow LAN access to selected Wireless Stations only , then each of your Wireless stations must have been selected, or access will be blocked. To see if radio interference is causing a problem, see if connection is possible when close to the Wireless Router. Remember that the connection range can be as little as 100 feet in poor environments. Problem 2: Wireless connection speed is very slow. Solution 2:

The wireless system will connect at the highest possible speed, depending on the distance and the environment. To obtain the highest possible con-

nection speed, you can experiment with the following:

Wireless Router location. Try adjusting the location and orientation of the Wireless Router. Wireless Channel If interference is the problem, changing to another channel may show a marked improvement. Radio Interference Other devices may be causing interference. You can experiment by switching other devices Off, and see if this helps. Any "noisy" devices should be shielded or relocated. RF Shielding Your environment may tend to block transmission between the wireless stations. This will mean high access speed is only possible when close to the Wireless Router. 46 Model No.: WR254 Appendix B About Wireless LANs B This Appendix provides some background information about using Wireless LANs (WLANs). Modes Wireless LANs can work in either of two (2) modes:

Ad-hoc Infrastructure Ad-hoc Mode Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Sta-

tions (e.g. notebook PCs with wireless cards) communicate directly with each other. Infrastructure Mode In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations

(e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations can then access all LAN resources. Access Points can only function in "Infrastructure" mode, and can communicate only with Wireless Stations which are set to "Infrastructure" mode. BSS/ESS BSS A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form a Basic Service Set (BSS). Using the same SSID is essential . Devices with different SSIDs are unable to communicate with each other. ESS A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID), form an Extended Service Set (ESS). Different Access Points within an ESS can use different Channels. In fact, to reduce interfer-

ence, it is recommended that adjacent Access Points SHOULD use different channels. As Wireless Stations are physically moved through the area covered by an ESS, they will automatically change to the Access Point which has the least interference or best performance. This capability is called Roaming. (Access Points do not have or require Roaming capabili-

ties.) Model No: WR254 Channels The Wireless Channel sets the radio frequency used for communication. Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adja-

cent Access Points use different Channels to reduce interference. In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than one Access Point can be used, the one with the strongest sig-

nal is used. (This can only happen within an ESS.) If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same Channel. However, most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join. WEP WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmitted. This is desirable because it is impossible to prevent snoopers from receiving any data which is transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless unless the receiver can decrypt it. If WEP is used, the Wireless Stations and the Access Point must have the same settings for each of the following:

WEP Key WEP Authentication Off, 64 Bit, 128 Bit For 64 Bit encryption, the Key value must match. For 128 Bit encryption, the Key value must match Open System or Shared Key. Wireless LAN Configuration To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point must use the same settings, as follows:

Mode On client Wireless Stations, the mode must be set to "Infrastructure".

(The Access Point is always in "Infrastructure" mode.) WEP SSID (ESSID) Wireless Stations should use the same SSID (ESSID) as the Access Point they wish to connect to. Alternatively, the SSID can be set to

"any" or null (blank) to allow connection to any Access Point. The Wireless Stations and the Access Point must use the same settings for WEP (Off, 64 Bit, 128 Bit). WEP Key: If WEP is enabled, the Key must be the same on the Wire-

less Stations and the Access Point. WEP Authentication: If WEP is enabled, all Wireless Stations must use the same setting as the Access Point (either "Open System" or

"Shared Key"). 48 C Model No.: WR254 Appendix C Specifications Multi-Function Wireless Router Model Dimensions Operating Temperature Storage Temperature Network Protocol:

Unnumbered IP with PPPoE is also supported. Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the Wireless Router supports both Dynamic IP Address (IP Address is allocated on connection) and Fixed IP Address. Model No.: WR254 Advanced Internet Functions Communication Applications. Support for Internet communication applications, such as interactive Games, Telephony, and Conferencing applications, which are often difficult to use when behind a Firewall, is included. Special Internet Applications. Applications which use non-standard connections or port numbers are normally blocked by the Firewall. The ability to define and allow such applications is provided, to enable such applications to be used normally. Virtual Servers. This feature allows Internet users to access Internet servers on your LAN. The required setup is quick and easy. DDNS Support. DDNS (Dynamic DNS) allows Internet users to connect to Virtual Servers on your LAN using a domain name, even if your IP address is not fixed. Multi-DMZ. For each WAN (Internet) IP address allocated to you, one (1) PC on your local LAN can be configured to allow unrestricted 2-way communication with Servers or individual users on the Internet. This provides the ability to run programs which are incompatible with Firewalls. URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users. Internet Access Log. See which Internet connections have been made. Access Control. Using the Access Control feature, you can assign LAN users to different groups, and determine which Internet services are available to each group. VPN Pass through Support. PCs with VPN (Virtual Private Networking) software using PPTP, L2TP and IPSec are transparently supported - no configuration is required. Wireless Features Standards Compliant. The Wireless Router complies with the IEEE802.11g (DSSS) specifications for Wireless LANs. Supports both 802.11b and 802.11g Wireless Stations. The 802.11g standard provides for backward compatibility with the 802.11b standard, so both 802.11b and 802.11g Wireless stations can be used simultaneously. Speeds to 54Mbps. All speeds up to the 802.11g maximum of 54Mbps are supported. WEP support. Support for WEP (Wired Equivalent Privacy) is included. Key sizes of 64 Bit and 128 Bit are supported. Wireless MAC Access Control. The Wireless Access Control feature can check the the MAC address (hardware address) of Wireless stations to ensure that only trusted Wireless Stations can Simple Configuration. If the default settings are unsuitable, they can be changed quickly and access your LAN. easily. Model No.: WR254 LAN Features 4-Port Switching Hub. The Wireless Router incorporates a 4-port 10/100BaseT switching hub, making it easy to create or extend your LAN. DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP address to PCs and other devices upon request. The Wireless Router can act as a DHCP Server for devices on your local LAN and WLAN.

Configuration & Management Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configuration. Configuration File Upload/Download. Save (download) the configuration data from the Wireless Router to your PC, and restore (upload) a previously-saved configuration file to the Wireless Router. Remote Management. The Wireless Router can be managed from any PC on your LAN. And, if the Internet connection exists, it can also (optionally) be configured via the Internet. Network Diagnostics. You can use the Wireless Router to perform a Ping or DNS lookup. UPnP Support. UPnP (Universal Plug and Play) allows automatic discovery and configuration of the Wireless Router. UPnP is by supported by Windows ME, XP, or later. Security Features Password - protected Configuration . Optional password protection is provided to prevent unauthorized users from modifying the configuration data and settings. Wireless LAN Security . WEP (Wired Equivalent Privacy) is supported, as well as Wireless access control to prevent unknown wireless stations from accessing your LAN. NAT Protection. An intrinsic side effect of NAT (Network Address Translation) technology is that by allowing all LAN users to share a single IP address, the location and even the existence of each PC is hidden. From the external viewpoint, there is no network, only a single device - the Stateful Inspection Firewall. All incoming data packets are monitored and all incoming server requests are filtered, thus protecting your network from malicious attacks from external Protection against DoS attacks. DoS (Denial of Service) attacks can flood your Internet connection with invalid packets and connection requests, using so much bandwidth and so many resources that Internet access becomes unavailable. The Wireless Router incorporates protection Wireless Router. sources. against DoS attacks.
