12/23/2002 2503500600 81. Introduction Congratulations on the purchase of your new Wireless Router. The Wireless Router is a multi-function device providing the following services: a) Wireless LAN Access Point for equipment compliant with the IEEE802.11b (DSSS) specifications. b) Shared Broadband Internet Access for both LAN (Ethernet) and WLAN (Wireless LAN) users. c) 4-Port Switching Hub for 10BaseT or 100BaseT connections. Figure 1: Network Connection The Wireless Router incorporates many advanced features, carefully designed to provide sophisticated functions while being easy to use. 1.1 Internet Access Features a) 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 Address Translation). b) DSL and cable modem Support. The Wireless Router has a 10BaseT Ethernet port for connecting a DSL or cable modem. All popular DSL and cable modems are supported. c) PPPoE and PPTP Support. The Internet (WAN port) connection supports PPPoE (PPP over Ethernet) and PPTP (Peer-to-Peer Tunneling Protocol), as well as "Direct Connection" type services. d) 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. 1.2 Advanced Internet Functions a) Conferencing & Telephony Applications. Internet Telephony and Conferencing applications, which are often difficult to use when behind a Firewall, are supported. b) Special Internet Applications. Applications that use non-standard
12/23/2002 2503500600 9connections 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. c) Virtual Servers. This feature allows Internet users to access Internet servers on your LAN. The required setup is quick and easy. d) DMZ. One 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 that are incompatible with Firewalls. e) URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users, or Wireless LAN users. f) Internet Access Log. See which Internet connections have been made. g) VPN Support. VPN (Virtual Private Networking) connections using PPTP and IPSec are transparently supported - no configuration is required. 1.3 Wireless Features a) Standards Compliant. The Wireless Router complies with the IEEE802.11b (DSSS) specifications for Wireless LAN. b) WEP Support. Support for WEP (Wired Equivalent Privacy) is included. Both 64 Bit and 128 Bit keys can be used. c) Access Control. The Access Control feature can ensure that only trusted Wireless Stations can access your LAN. d) Simple Configuration. If the default settings are unsuitable, they can be changed quickly and easily. 1.4 LAN Features a) 4-Port Switching Hub. The Wireless Router incorporates a 4-port 10/100BaseT switching hub, making it easy to create or extend your LAN. b) 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. c) 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. 1.5 Configuration & Management a) Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configuration. b) 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. c) UPnP Support. UPnP (Universal Plug and Play) allows automatic discovery and configuration of the Wireless Router. UPnP is supported by Windows Me, XP, or later.
12/23/2002 2503500600 101.6 Security Features a) Password Protected Configuration. Optional password protection is provided to prevent unauthorized users from modifying the configuration data and settings. b) Wireless LAN Security. WEP (Wired Equivalent Privacy) is supported, as well as Wireless access control to prevent unknown wireless stations from accessing your LAN. c) 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. d) Stateful Inspection Firewall. All incoming data packets are monitored and all incoming server requests are filtered, i.e., protecting your network from malicious attacks from external sources. e) 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 against DoS attacks. 1.7 Package Contents The following items should be included: a) One Wireless Router Unit (the device). b) One Power adapter. c) One User’s Manual d) One Quick Installation Guide.

SSID (ESSID) This must match the value used on the Wireless Router. Note that the SSID is case sensitive. WEP By default, WEP on the Wireless Router is disabled. If WEP remains disabled on the Wireless Router, all stations must have WEP disabled; otherwise, each station must use the same settings as the Wireless Router. 4. Configuration Program The Wireless Router comes with a web-based tool that you can use to set up and customize its settings. You can access this tool from any computer on your network. For best results, either use Microsoft Internet Explorer version 5.0 or later,
12/23/2002 2503500600 25or Netscape Navigator version 4.7 or later. 4.1 Collecting ISP Information You will need to find out some information from your ISP before you can configure your Wireless Router, such as: a) Has your ISP assigned you a static IP address, or will they assign one to you dynamically? If they have given you a static IP, what is it? b) Does your ISP use PPPoE? If so, what is your PPPoE username and password? Call your ISP if you’re not sure of the answers to these questions. 4.2 Preparation Before attempting to configure the Wireless Router, please ensure that: a) Your PC can establish a physical connection to the Wireless Router. The PC and the Wireless Router must be directly connected and on the same LAN segment. b) The Wireless Router must be installed and powered on. c) If the Wireless Router's default IP address (192.168.62.1) has already used by another device, the other device must be turned off until the Wireless Router is allocated a new IP address during configuration. 4.3 Connecting to the Wireless Router 4.3.1 Using UPnP If your Windows system supports UPnP, an icon for the Wireless Router will appear in the system tray, notifying you that a new network device has been found, and offering to create a new desktop shortcut to the newly-discovered device. a) Unless you intend to change the IP address of the Wireless Router, you can accept the desktop shortcut. b) Whether you accept the desktop shortcut or not, you can always find UPnP devices in My Network Places (previously called Network Neighborhood). c) Double - click the icon for the Wireless Router (either on the Desktop, or in My Network Places) to start the configuration. 4.3.2 Using your Web Browser To establish a connection from your PC to the Wireless Router: a) After installing the Wireless Router in your LAN, start your PC. If your PC has already running, restart it. b) Start your Web browser. c) In the Address box, enter "HTTP://" and the IP address of the Wireless Router, as in this example, which uses the Wireless Router's default IP address: HTTP://192.168.62.1.
12/23/2002 2503500600 264.3.3 If you can't connect If the Wireless Router does not respond, check the following. a) The Wireless Router is properly installed, LAN connection is OK, and it is powered on. You can test the connection by using the "Ping" command: Open the MS-DOS window or command prompt window. Enter the command: ping 192.168.62.1. If no response is received, either the connection is not working, or your PC's IP address is not compatible with the Wireless Router's IP address. See the next item. b) If your PC is using a fixed IP address, its IP address must be within the range 192.168.62.2 to 192.168.62.254 to be compatible with the Wireless Router's default IP address of 192.168.62.1. Also, the Network Mask must be set to 255.255.255.0. See Chapter 3 - PC Configuration for details on checking your PC's TCP/IP settings. c) 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. 4.4 Open the Web-based Admin Tool The Wireless Router comes with a web-based tool that you can use to set up and customize its settings. You can access this tool from any computer on your network. a) Open a browser on your PC. b) Type http://192.168.62.1 in the Address field: Figure 17: Web Address for Admin Tool A logon dialog box will appear: Figure 18: Username/Password Dialog Box
12/23/2002 2503500600 27Type “admin” in the User Name field. Then, type a password and click OK. The default password is 1234. c) The Wireless Router Admin Tool will appear. Note that the web-based Admin Tool will log you out after a certain period of idle time. If this happens, you will need to re-enter your user name and password. 5. Configuring Your Wireless Router - Basic Functions Basic administrative functions include Setup, Global Address, Wireless, Tools, Status, DHCP, Log , and Statistics. 5.1 Setup The Setup screen shows the basic configuration parameters for your Wireless Router, such as Host Name, LAN IP address, and PPPoE Login. Although most users will be able to accept the default settings, every Internet Service Provider (ISP) is different. Check with your ISP if you are not sure which settings they require. The Setup screen is shown in the figure below. Figure 19: Setup Screen Note that the graphics shown in this manual may differ slightly from your Wireless Router’s screens. The images that appear here are provided as examples only. 5.1.1 Configure Setup Parameters a) Type the Host Name (optional). This value is sometimes called System Name or Account Name. Check with your ISP if you are not sure whether to provide this information. b) Type the Domain Name of your ISP, such as xyz.isp.com (optional). Check with your ISP if you are not sure whether to provide this information. c) Review the Firmware Version. This value tells you the version number and date of the firmware you are currently using.
12/23/2002 2503500600 28d) Review the LAN IP Address information and change if necessary. These fields show the Device IP Address and Subnet Mask as seen by others on your Local Area Network (LAN). Most users will not need to change these values. Note that if you change the LAN IP address with the DHCP server running, you will need to restart your client machines. If you change the LAN IP address without the DHCP server running, you will need to manually reconfigure your clients' IP addresses. e) For WAN IP Address (also called the Public IP), choose either Obtain an IP Address Automatically (most users) or Specify an IP Address (if your ISP assigns static IPs). If you choose the second option, type in the Wide Area Network (WAN) IP Address, Subnet Mask, ISP Gateway Address, and DNS information. Your ISP should provide these values. f) Select your Point-to-Point Protocol over Ethernet (PPPoE) settings. PPPoE allows your ISP to authenticate your connection by requiring you to submit a username and password. If your ISP uses PPPoE, choose Enable and go on to Step g; otherwise, choose Disable and skip to Step i. Note that if you enable PPPoE, make sure to uninstall any existing PPPoE applications on any of the PCs in your network. g) Type in the PPPoE User Name and Password provided by your ISP. h) Choose either Connect on Demand or Keep Alive. If you choose Connect on Demand, the PPPoE connection will be disconnected after a certain period of inactivity. You can specify the length of this period, in minutes, in the Max Idle Time field. If you have been disconnected due to inactivity, your Wireless Router will automatically re-connect when you attempt to access the Internet. If you choose Keep Alive, you will have perpetual access. i) Click Apply when you finish choosing your settings, or click Cancel to undo your changes. 5.2 Global Address Use the Global Address screen to set up Network Address Translation (NAT), a process that provides internal to external IP address mapping. If your Wireless Router is configured to retrieve an IP address dynamically, you will not need to use this function. Note that in order to use the Global Address mapping function, you must have NAT enabled in the Filters screen. See Section 0 6.3 Filters for more information. The Global Address screen is shown in the figure below.

Troubleshooting This chapter covers some common problems that may be encountered while using the Wireless 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. 7.1 General Problems Problem 1: Can't connect to the Wireless Router to configure it. Solution 1: Check the following: a) The Wireless Router is properly installed, LAN connections are Ok, and it is powered on. b) 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.) c) If your PC is set to "Obtain an IP Address automatically" (DHCP client), restart it. d) If your PC uses a Fixed (Static) IP address, ensure that it is using an IP Address within the range 192.168.62.2 to 192.168.62.254 and thus compatible with the Wireless Router's default IP Address of 192.168.62.1. 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. 7.2 Internet Access Problem 1: When I enter a URL or IP address I get a timed out error. Solution 1: A number of things could be causing this. Try the following troubleshooting steps. a) 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. b) 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.

Problem 2: Some applications do not run properly when using the Wireless Router. 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 applications that do not function correctly. If this does solve the problem, you can use the DMZ function. This should work with almost every application, but: a) It is a security risk, since the firewall is disabled. b) Only one PC can use this feature. 7.3 Wireless Access Problem 1: My PC can't locate the Wireless Access Point. Solution 1: Check the following. a) Your PC is set to Infrastructure Mode. Access Points are always in Infrastructure Mode. b) 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 "work-group". c) Both your PC and the Wireless Access Point 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. d) If WEP is enabled on the Wireless Router, your PC must have WEP enabled, and the key tables (for 64 Bit encryption) or key (for 128 Bit encryption) must match. e) 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. f) To see if radio interference is causing a problem, see if connection is possible when close to the Wireless Access Point. Remember that the connection range can be as little as 100 feet in poor environments.

To obtain the highest possible connection speed, you can experiment with the following. a) Access Point location. Try adjusting the location and orientation of the Access Point. b) Wireless Channel. If interference is the problem, changing to another channel may show a marked improvement. c) 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. d) 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 Access Point. 8. About Wireless LANs This chapter provides some background information about using Wireless LANs (WLANs). 8.1 Modes Wireless LANs can work in either of two modes, Ad-hoc and Infrastructure. 8.1.1 Ad-hoc Mode Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Stations, e.g. notebook PCs with wireless cards, communicate directly with each other. 8.1.2 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 that are set to "Infrastructure" mode.

Devices with different SSIDs are unable to communicate with each other. 8.2.2 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 interference, 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 that has the least interference or best performance. This capability is called Roaming. Access Points do not have or require Roaming capabilities. 8.3 Channels The Wireless Channel sets the radio frequency used for communication. a) 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 channels are available. If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference. b) 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 signal is used. This can only happen within an ESS. c) 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. 8.4 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 that is transmitted by your Wireless Stations. But, if the data is encrypted, then it is meaningless unless the receiver can decrypt it.

Key For 64-bit encryption, the Key Table must match. For 128-bit encryption, the Key value must match. WEP Authentication Open System, Shared Key, or both.
