Congratulations on the purchase of your new Wireless Router. The Wireless Router is a multifunction 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 802.11a, 802.11b and 802.11g Wireless Stations. Figure 1: Wireless Router 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 Address 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, PPTP, SingTel RAS and Telstra Big Pond Support. The Internet (WAN port) connection supports PPPoE (PPP over Ethernet), PPTP (Peer-to-Peer Tunneling Protocol), SingTel RAS and Telstra Big Pond (Australia), as well as "Direct Connection" type services. Unnumbered IP with PPPoE is also supported. Wireless Router User Guide • 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. 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 IEEE802.11a and IEEE802.11g (DSSS) specifications for Wireless LANs. • Supports 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. • WPA-PSK support. The WPA-PSK (Pre-shared Key) standard provides greater security for your Wireless clients than WEP. • WEP support. Support for WEP (Wired Equivalent Privacy) is included. Key sizes of 64 Bit and 128 Bit are supported. • Wireless MAC-level Access Control. The Wireless Access Control feature can check 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. Introduction 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. 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 . WPA-PSK and WEP (Wired Equivalent Privacy) are supported, as well as MAC-level 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 incoming 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 bandwidth and so many resources that Internet access becomes unavailable. The Wireless Router incorporates protection against DoS attacks.

This enables you to connect to it, and configure it, using your Web Browser. Your Browser must support JavaScript. The configuration program has been tested on the following browsers: • Netscape V4.08 or later • Internet Explorer V4 or later Preparation Before attempting to configure the Wireless Router, please ensure that: • Your PC can establish a physical connection to the Wireless Router. The PC and the Wireless Router must be directly connected (using the Hub ports on the Wireless Router) or on the same LAN segment. • The Wireless Router must be installed and powered ON. • If the Wireless Router's default IP Address (192.168.0.1) is already used by another device, the other device must be turned OFF until the Wireless Router is allocated a new IP Address during configuration. 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. • Unless you intend to change the IP Address of the Wireless Router, you can accept the desktop shortcut. • Whether you accept the desktop shortcut or not, you can always find UPnP devices in My Network Places (previously called Network Neighborhood). • Double - click the icon for the Wireless Router (either on the Desktop, or in My Network Places) to start the configuration. Refer to the following section Setup Wizard for details of the initial configuration process. Using your Web Browser To establish a connection from your PC to the Wireless Router: 1. After installing the Wireless Router in your LAN, start your PC. If your PC is already running, restart it. 2. Start your WEB browser. 3. 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://192.168.0.1 Because the default password is blank, your will not be prompted for a password. However, you should use the Password screen to assign a password. 11 Wireless Router User Guide If you can't connect If the Wireless Router does not respond, check the following: • 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 192.168.0.1 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 next item.) • If your PC is using a fixed IP Address, its IP Address must be within the range 192.168.0.2 to 192.168.0.254 to be compatible with the Wireless Router's default IP Address of 192.168.0.1. Also, the Network Mask must be set to 255.255.255.0. See Chapter 4 - PC Configuration for details on checking your PC's TCP/IP settings. • 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.) • Ensure you are using the wired LAN interface. The Wireless interface can only be used if its configuration matches your PC's wireless settings. 12 Setup Setup Wizard The first time you connect to the Wireless Router, the Setup Wizard will run automatically. (The Setup Wizard will also run if the Wireless Router's default settings are restored.) 1. Step through the Wizard until finished. • You need to know the type of Internet connection service used by your ISP. Check the data supplied by your ISP. • The common connection types are explained in the tables below. 2. On the final screen of the Wizard, run the test and check that an Internet connection can be established. 3. If the connection test fails: • Check your data, the Cable/DSL modem, and all connections. • Check that you have entered all data correctly. • If using a Cable modem, your ISP may have recorded the MAC (physical) address of your PC. Run the Wizard, and on the Cable Modem screen, use the "Clone MAC address" button to copy the MAC address from your PC to the Wireless Router.

Figure 5: Home Screen Navigation & Data Input • Use the menu bar on the left of the screen, and the "Back" button on your Browser, for navigation. • Changing to another screen without clicking "Save" does NOT save any changes you may have made. You must "Save" before changing screens or your data will be ignored. On each screen, clicking the "Help" button will display help for that screen. From any help screen, you can access the list of all help files (help index). 15 Wireless Router User Guide LAN Screen Use the LAN link on the main menu to reach the LAN screen. An example screen is shown below. Figure 6: LAN Screen Data - LAN Screen TCP/IP IP Address IP address for the Wireless Router, as seen from the local LAN. Use the default value unless the address is already in use or your LAN is using a different IP address range. In the latter case, enter an unused IP Address from within the range used by your LAN. Subnet Mask The default value 255.255.255.0 is standard for small (class "C") networks. For other networks, use the Subnet Mask for the LAN segment to which the Wireless Router is attached (the same value as the PCs on that LAN segment). DHCP Server • If Enabled, the Wireless Router will allocate IP Addresses to PCs (DHCP clients) on your LAN when they start up. The default (and recommended) value is Enabled. • If you are already using a DHCP Server, this setting must be Disabled, and the existing DHCP server must be re-configured to treat the Wireless Router as the default Gateway. See the following section for further details. • The Start IP Address and Finish IP Address fields set the values used by the DHCP server when allocating IP Addresses to DHCP clients. This range also determines the number of DHCP clients supported. See the following section for further details on using DHCP. Buttons Save Save the data on screen. Cancel The "Cancel" button will discard any data you have entered and reload the file from the Wireless Router. 16 Setup DHCP What DHCP Does A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to a DHCP Client (PC or device) upon request. • The client request is made when the client device starts up (boots). • The DHCP Server provides the Gateway and DNS addresses to the client, as well as allocating an IP Address. • The Wireless Router can act as a DHCP server. • Windows 95/98/ME, Windows 2000 and Windows XP act as a DHCP client. This is the default Windows setting for the TCP/IP network protocol. However, Windows uses the term Obtain an IP Address automatically instead of "DHCP Client". • You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your LAN does not have other Routers, this means there must only be one (1) DHCP Server on your LAN.) Using the Wireless Router's DHCP Server This is the default setting. The DHCP Server settings are on the LAN screen. On this screen, you can: • Enable or Disable the Wireless Router's DHCP Server function. • Set the range of IP Addresses allocated to PCs by the DHCP Server function. You can assign Fixed IP Addresses to some devices while using DHCP, provided that the Fixed IP Addresses are NOT within the range used by the DHCP Server. Using another DHCP Server You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP Server, rather than the Wireless Router's, the following procedure is required. 1. Disable the DHCP Server feature in the Wireless Router. This setting is on the LAN screen. 2. Configure the DHCP Server to provide the Wireless Router's IP Address as the Default Gateway. To Configure your PCs to use DHCP This is the default setting for TCP/IP under Windows 95/98/ME. See Chapter 4 - Client Configuration for the procedure to check these settings. 17 Wireless Router User Guide Wireless Screen The Wireless Router's settings must match the other Wireless stations. Note that the Wireless Router will automatically accept both 802.11b and 802.11g connections, and no configuration is required for this feature. To change the Wireless Router's default settings for the Wireless Access Point feature, use the Wireless link on the main menu to reach the Wireless screen. An example screen is shown below. Figure 7: Wireless Screen Data - Wireless Screen Access Point Enable Access Poi nt · If Enabled, wireless stations will be able to use this Access Point. · If Disabled, the wireless interface is disabled, and will neither transmit or receive wireless traffic. Broadcast SSID If Enabled, the SSID will be broadcast its name to all Wireless Stations. Stations can then see this Access Point in their list of "Available networks", and can adopt the correct SSID for connections to this Access Point. Station name On your PC, some Wireless status screens may display this name as the Access Point in use. Region The region can not be changed by users 18 Setup Band 2.4GHz To use the 2.4GHz band, select this radio button, then the desired option: • 802.11g & 802.11b - This is the default, and should normally be used. • 802.11g only - If selected, this ensures that "g" mode stations will connect at high speed, but "b" mode stations will be unable to connect at all. • 802.11b only - If selected, 802.11g mode is unavailable. 802.11g mode stations will only be able to connect if they are fully backward-compatible with 802.11b mode. Network Name (SSID) Enter the desired network name for the 2.4GHz (802.11b/g) band. To communicate, all Wireless stations must use the same SSID/ESSID. 5GHz Select this radio button if you wish to use the 5GHz band. This will allow 802.11a connections to this Access Point. Network Name (SSID) Enter the desired network name for the 5GHz (802.11a) band. To communicate, all Wireless stations must use the same SSID/ESSID. Wireless Security Current Setting The current security setting is displayed. Configure Button Click this button to access the Wireless security sub-screen, and modify the security settings as required. MAC Level Access Control Allow LAN access Allow Internet access This feature can be used to prevent unknown Wireless stations from accessing your LAN. The available options are: • All Wireless Stations - All wireless stations can use the access point to access your LAN. • Selected Wireless stations only - Only selected wireless stations access your LAN. To select the required wireless stations, click the "Select Stations" button. This feature can prevent unknown Wireless stations from using the Wireless Router to access the Internet. The available options are: • All Wireless Stations - All wireless stations can use the access point to access the Internet. • Selected Wireless stations only - Only selected wireless stations can use the access point to access the Internet. To select the required wireless stations, click the "Select Stations" button. 19 Wireless Router User Guide Wireless Security This screen is accessed by clicking the "Configure" button on the Wireless screen. There are 3 options for Wireless security: • Disabled - no data encryption is used. • WEP - data is encrypted using the WEP standard. • WPA-PSK - data is encrypted using the WPA-PSK standard. This is a later standard than WEP, and provides much better security than WEP. If all your Wireless stations support WPA-PSK, you should use WPA-PSK rather than WEP. WEP Wireless Security Figure 8: WEP Screen Data - WEP Screen Security System WEP Authentication Normally this can be left at the default value of "Auto". If that fails, select the appropriate value - "Open System" or "Shared Key." Check your wireless station's documentation to see what method to use. Data Key Size Select the WEP Encryption level: Passphrase The 802.11b standard. Data is encrypted before transmission, but the encryption system is not very strong. • 64-bit (sometimes called 40-bit) encryption • 128-bit (sometimes called 104 bit) encryption This feature allows you to generate a key or keys from a text (ASCII) phrase, rather than enter keys in Hex. To use this feature: • Enter a word or group of printable characters in the Passphrase field 20 Setup Keys • Click the "Generate Keys" button. • If encryption strength is set to 64 bit, then each of the four key fields will be populated with key values. If encryption strength is set to 128 bit, then only the selected WEP key field will be given a key value. All wireless stations must use the same key values as the Wireless Router. • Use the radio buttons to select the default key. • Enter the key value you wish to use. Other stations must have the same key values. • Keys must be entered in Hex. Hex characters are the digits (0 ~ 9) and the letters A ~ F. 21 Wireless Router User Guide WPA-PSK Wireless Security If "WPA-PSK" is selected, the screen will look like the following example. Figure 9: WPA-PSK Screen Data – WPA-PSK Screen Security System WPA-PSK PSK Enter the Keyword key value. Data is encrypted using a key derived from the network key. Other Wireless Stations must use the same network key. The PSK must be from 8 to 63 characters in length. Key Lifetime This determines how often the encryption key is changed. You can change the default value if desired. WPA Encryption The WPA-PSK standard allows different encryption methods to be used. Select the desired option. Wireless Stations must use the same encryption method. Like WEP, data is encrypted before transmission. WPA is more secure than WEP, and should be used if possible. WPA-PSK is the version of WPA, which does NOT require a Radius Server on your LAN. 22 Setup Password Screen The password screen allows you to assign a password to the Wireless Router. Figure 10: Password Screen Once you have assigned a password to the Wireless Router (on the Password screen above) you will be prompted for the password when you connect, as shown below. (If no password has been set, this dialog will not appear.) Figure 11: Password Dialog • Leave the "User Name" blank. • Enter the password for the Wireless Router, as set on the Password screen above. 23 Chapter 4 PC Configuration This Chapter details the PC Configuration required on the local ("Internal") LAN. Overview For each PC, the following may need to be configured: • TCP/IP network settings • Internet Access configuration • Wireless configuration Windows Clients This section describes how to configure Windows clients for Internet access via the Wireless Router. The first step is to check the PC's TCP/IP settings. The Wireless Router uses the TCP/IP network protocol for all functions, so it is essential that the TCP/IP protocol be installed and configured on each PC. TCP/IP Settings - Overview If using the default Wireless Router settings, and the default Windows TCP/IP settings, no changes need to be made. • By default, the Wireless Router will act as a DHCP Server, automatically providing a suitable IP Address (and related information) to each PC when the PC boots. • For all non-Server versions of Windows, the default TCP/IP setting is to act as a DHCP client. If using a Fixed (specified) IP address, the following changes are required: • The Gateway must be set to the IP address of the Wireless Router • The DNS should be set to the address provided by your ISP. If your LAN has a Router, the LAN Administrator must reconfigure the Router itself. Refer to Chapter 8 - Advanced Setup for details. 24 PC Configuration Checking TCP/IP Settings - Windows 9x/ME: 1.

Click the View Log button on the Access Control screen to view this log. This log shows attempted Internet accesses which have been blocked by the Access Control function. Data shown in this log is as follows: Date/Time Date and Time of the attempted access. Name If known, the name of the PC whose access was blocked. Source IP address The IP Address of the PC or device whose access request was blocked MAC address The hardware or physical address of the PC or device whose access request was blocked Destination The destination URL or IP address 55 Wireless Router User Guide Dynamic DNS (Domain Name Server) This free service is very useful when combined with the Virtual Server feature. It allows Internet users to connect to your Virtual Servers using a URL, rather than an IP Address. This also solves the problem of having a dynamic IP address. With a dynamic IP address, your IP address may change whenever you connect, which makes it difficult to connect to you. The Service works as follows: 1. You must register for the service at one of the listed DDNS Service Providers. 2. After registration, follow the service provider's procedure to request a Domain Name and have it allocated to you. 3. Enter your DDNS data on the Wireless Router's DDNS screen. 4. The Wireless Router will then automatically ensure that your current IP Address is recorded at the DDNS server. If the DDNS Service provides software to perform this "IP address update"; you should disable the "Update" function, or not use the software at all. 5. From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC) using your Domain Name. Dynamic DNS Screen Select Advanced on the main menu, then Dynamic DNS, to see a screen like the following: Figure 33: DDNS Screen Data - Dynamic DNS Screen DDNS Service DDNS Service Select the desired DDNS Service provider.

Using a Special Application • Configure the Special Applications screen as required. • On your PC, use the application normally. Remember that only one (1) PC can use each Special application at any time. Also, when 1 PC is finished using a particular Special Application, there may need to be a "Time-out" before another PC can use the same Special Application. The "Time-out" period may be up to 3 minutes. If an application still cannot function correctly, try using the "DMZ" feature. DMZ • The "DMZ" PC will receive all "Unknown" connections and data. This feature is normally used with applications which do not usually work when behind a Firewall. • The DMZ PC is effectively outside the Firewall, making it more vulnerable to attacks. For this reason, you should only enable the DMZ feature when required. • If Enabled, you must select the PC to be used as the "DMZ" PC. Select the desired option • Disabl ed - DMZ is disabled. • Enabled- The selected PC is a standard PC on your LAN, but it will receive any "unknown" connections and data, as described above. 60 Advanced Features Multi-DMZ This feature is only available if your ISP has allocated you multiple Internet IP addresses. If you have multiple Internet IP addresses, you can assign one DMZ PC for each Internet IP address. • The "DMZ PC" will receive all "Unknown" connections and data received for the Internet IP address associated with it. • All outgoing traffic from the DMZ PC will be assigned the WAN IP address associated with it, rather than the shared IP address on the WAN port. Note that ONLY the DMZ PC will use the WAN (Internet) IP address you enter on this screen. To use this feature: • Enter an IP address allocated to you by your ISP into the WAN IP address field. • Select the PC to be the DMZ PC for traffic sent to this IP address. • Enable this DMZ. The "DMZ PC" is effectively outside the Firewall, making it more vulnerable to attacks. For this reason, you should only enable the DMZ feature when required. 61 Wireless Router User Guide URL Filter The URL Filter allows you to block access to undesirable Web site • To use this feature, you must define "filter strings". If the "filter string" appears in a requested URL, the request is blocked. • Enabling the URL Filter also affects the Internet Access Log. If Enabled, the "Destination" field in the log will display the URL. Otherwise, it will display the IP Address. URL Filter Screen Click the "URL Filter" on the Advanced screen to access the URL Filter screen. An example screen is shown below. Figure 36: URL Filter Screen Data - URL Filter Screen Settings Enable This lists any existing entries. If you have not entered any values, this list will be empty. Schedule If you always want filtering to be active, select "Always". Otherwise, select the schedule to use. You can define the schedule using the Schedule menu option, on the Advanced menu. Apply Filter to Select the groups you wish the filter to apply to. Group membership can be set on the "User Groups" screen, on the "Administration" menu.

Add Button Use this to add the entry in the "Filter String" above to the list. Add Filter Delete/Delete All Use these buttons to delete the selected entry or all entries, as required. Multiple entries can be selected by holding down the CTRL key while selecting.(On the Macintosh, hold the SHIFT key while selecting.) Add Use this to add the current Filter String to the site list. 63 Wireless Router User Guide Define Schedule The schedule can be used for the Access Control and URL Filter features. • Two (2) separate sessions or periods can be defined. • Times must be entered using a 24 hr clock. • If the time for a particular day is blank, no action will be performed. Figure 37: Define Schedule Screen Data – Define Schedule Screen Day Each day of the week can scheduled independently. Session 1 Session 2 Two (2) separate sessions or periods can be defined. Session 2 can be left blank if not required. Start Time Enter the start using a 24 hr clock. Finish Time Enter the finish time using a 24 hr clock. 64 Advanced Features User Groups User Groups are used by the Access Control and the URL Filter features. • Groups are pre-named "Default", "Group 1", "Group 2", "Group 3" and "Group 4", and cannot be renamed. • All PCs are in the "Default" group, unless moved to another group. • A PC can be a member of 1 group only. • PCs must be in the "PC Database". If required, you can manually add PCs to the PC Database, using the PC Database option on the Administration menu. Figure 38: User Groups Screen Data – User Groups Screen Group List Select the desired Group. The screen will update to display the PCs for the selected Group. Group Members This lists all PCs , which are currently members of the selected group. Other PCs This lists all other PCs – those, which are not currently members of the selected group.

(Members can not be deleted from the "Default" group.) << Add Use this button to add members to the current Group. In the "Other PCs" list, select the members you wish to add to this group, and click this button. The PCs will be moved from their existing group to the current group. PCs not assigned to any group will be in the "Default" group. PCs deleted from any other Group will be added to the "Default" group. 65 Wireless Router User Guide Virtual Servers This feature, sometimes called Port Forwarding, allows you to make Servers on your LAN accessible to Internet users. Normally, Internet users would not be able to access a server on your LAN because: • Your Server does not have a valid external IP Address. • Attempts to connect to devices on your LAN are blocked by the firewall in this device. The "Virtual Server" feature solves these problems and allows Internet users to connect to your servers, as illustrated below. Figure 39: Virtual Servers IP Address seen by Internet Users Note that, in this illustration, both Internet users are connecting to the same IP Address, but using different protocols. To Internet users, all virtual Servers on your LAN have the same IP Address. This IP Address is allocated by your ISP. This address should be static, rather than dynamic, to make it easier for Internet users to connect to your Servers. However, you can use the DDNS (Dynamic DNS) feature to allow users to connect to your Virtual Servers using a URL, instead of an IP Address. Virtual Servers Screen The Virtual Servers screen is reached by the Virtual Servers link on the Advanced screen. An example screen is shown below. 66 Advanced Features Figure 40: Virtual Servers Screen This screen lists a number of pre-defined Servers, and allows you to define your own Servers. Details of the selected Server are shown in the "Properties" area. Data - Virtual Servers Screen Servers Servers This lists a number of pre-defined Servers, plus any Servers you have defined. Details of the selected Server are shown in the "Properties" area. Properties Enable Use this to Enable or Disable support for this Server, as required. • If Enabled, any incoming connections will be forwarded to the selected PC. • If Disabled, any incoming connection attempts will be blocked. PC (Server) Select the PC for this Server. The PC must be running the appropriate Server software. Protocol Select the protocol (TCP or UDP) used by the Server. Internal Ports Enter the range of port numbers which the Server software is configured to use. If only 1 port number is required, enter it in both the start and finish fields. External Ports The port numbers used by Internet users when connecting to the Server. These are normally the same as the Internal Port Numbers. If it is different, this device will perform a "mapping" or "translation" function, allowing the server to use one port address, while clients use a different port address. Buttons Defaults This will delete any Servers you have defined, and set the predefined Servers to use their default port numbers. 67 Wireless Router User Guide Disable All This will cause the "Enable" setting of all Virtual Servers to be set OFF. Update Selected Server Update the current Virtual Server entry, using the data shown in the "Properties" area on screen. Add as new Server Add a new entry to the Virtual Server list, using the data shown in the "Properties" area on screen. The entry selected in the list is ignored, and has no effect. Delete Delete the current Virtual Server entry. Note that the pre-defined Servers can not be deleted. Only Servers you have defined yourself can be deleted. Clear Form Clear all data from the "Properties" area, ready for input of a new Virtual Server entry. For each entry, the PC must be running the appropriate Server software. Defining your own Virtual Servers If the type of Server you wish to use is not listed on the Virtual Servers screen, you can define and manage your own Servers: Create a new Server: Modify (Edit) a Server: Delete a Server: 1. Click "Clear Form" 2. Enter the required data, as described above. 3. Click "Add". 4. The new Server will now appear in the list. 1. Select the desired Server from the list 2. Make any desired changes (for example, change the Enable/Disable setting). 3. Click "Update" to save changes to the selected Server. 1. Select the entry from the list. 2. Click "Delete". Note: You can only delete Servers you have defined. Predefined Server cannot be deleted. From the Internet, ALL Virtual Servers have the IP Address allocated by your ISP. Connecting to the Virtual Servers Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the Internet IP Address (the IP Address allocated to you by your ISP). e.g. 68 Advanced Features http://203.70.212.52 ftp://203.70.212.52 It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic. However, you can use the Dynamic DNS feature, described in the following section, to allow users to connect to your Virtual Servers using a URL, rather than an IP Address. 69 Wireless Router User Guide WAN Port Configuration The WAN Port option is on the Advanced menu. Figure 41: WAN Port Screen Data – WAN Port Screen Port Settings Port Speed MTU Size Normally, this can be left at "Automatic". If the device attached to the WAN Port has problems making a connection, you can select the setting required or preferred by the other device. • MTU (Maximum Transmission Unit) value should only be changed if advised to do so by Technical Support. • Enter a value between 1 and 1500. • This device will still auto-negotiate with the remote server, to set the MTU size. The smaller of the 2 values (auto-negotiated, or entered here) will be used. • For direct connections (not PPPoE or PPTP), the MTU used is always 1500. Identification Hostname Normally, there is no need to change the default name, but if your ISP requests that you use a particular Hostname, enter it here. Domain Name If your ISP provided a domain name, enter it here. Otherwise, this may be left blank. 70 Advanced Features WAN Port MAC Address Also called Network Adapter Address or Physical Address. This is a low-level identifier, as seen from the WAN port. Normally there is no need to change this, but some ISPs require a particular value, often that of the PC initially used for Internet access. You can use the Copy from PC button to copy your PC's address into this field, the Default button to insert the default value, or enter a value directly. IP Address Automatic Also called Dynamic IP Address. This is the default, and the most common. Leave this selected if your ISP allocates an IP Address to the Wireless Router upon connection. Specified IP Address Also called Static IP Address. Select this if your ISP has allocated you a fixed IP Address. If this option is selected, the following data must be entered. • IP Address • Network Mask (Not required for PPPoE) The IP Address allocated by the ISP. This is also supplied by your ISP. It must be compatible with the IP Address above. • Gateway IP Address (Not required for PPPoE) The address of the router or gateway, as supplied by your ISP. DNS Automatically obtain from Serve The DNS (Domain Name Server) address will be obtained automatically from your ISP's server. Note that if using a fixed IP address, with no login (login is set to "None"), then no Server is used, so this option cannot be used. Use this DNS If this option is selected, you must enter the IP address of the DNS (Domain Name Server) you wish to use. 71 Wireless Router User Guide Login Login Method If your ISP does not use a login method (username, password) for Internet access, leave this at the default value None (Direct connection). Otherwise, check the documentation from your ISP, select the login method used, and enter the required data. • PPPoE - this is the most common login method, widely used with DSL modems. Normally, your ISP will have provided some software to connect and login. This software is no longer required, and should not be used. • PPPoE (Unnumbered IP) - this can only be used if your ISP supports this system, and has allocated you multiple IP addresses. If selected, you must also select "Specified IP Address" above and enter one of the IP addresses allocated to you by your ISP. The other IP addresses must be assigned to PCs on your LAN. • PPTP - this is mainly used in Europe. You need to know the PPTP Server address as well as your name and password. • L2TP - this is not widely used. You need to know the PPTP Server address as well as your name and password. • Big Pond Cable - for Australia only. • SingTel RAS - for Singapore only. Login User Name The User Name (or account name) provided by your ISP. Login Password Enter the password for the login name above. RAS Plan For SingTel customers only, select the RAS plan you are on. Server Address This is not required for PPPoE or SingTel RAS. For PPTP, L2TP and BPA, enter the Server address as provided by your ISP. Connection Behavior Auto-disconnect Idle Time-out Select the desired option: • Automatic Connect/Disconnect An Internet connection is automatically made when required, and disconnected when idle for the time period specified by the "Auto-disconnect Idle Time-out". • Manual Connect/Disconnect You must manually establish and terminate the connection. • Keep alive (maintain connection) The connection will never be disconnected by this device. If disconnected by your ISP, the connection will be re-established immediately. (However, this does not ensure that your Internet IP address will remain unchanged.) This field has no effect unless using the Automatic Connect/Disconnect setting. If using this setting, enter the desired idle time-out period (in minutes). After the connection to your ISP has been idle for this time period, the connection will be terminated. 72 Advanced Features Buttons Default Inserts the default MAC address into the MAC address field. You must click "Save" to actually change the address used. Copy from PC Inserts the MAC address from your PC into the MAC address field. You must click "Save" to actually change the address used. Save Save your changes to the Broadband Router. Cancel Reverse any changes made since the last "Save". 73 Chapter 7 Advanced Administration This Chapter explains the settings available via the "Administration" section of the menu.

Lookup Button After entering the Domain name/URL, click this button to start the "DNS Lookup" procedure. The results will be displayed in the DNS Lookup Results pane. 78 Advanced Administration Options This screen allows advanced users to enter or change a number of settings. For normal operation, there is no need to use this screen or change any settings. An example Options screen is shown below. Figure 45: Options Screen Data - Options Screen Backup DNS IP Address Enter the IP Address of the DNS (Domain Name Servers) here. These DNS will be used only if the primary DNS is unavailable. UpnP Enable UPnP Services Allow Configuration... Allow Internet access to be disabled • UPnP (Universal Plug and Play) allows automatic discovery and configuration of equipment attached to your LAN. UPnP is by supported Windows ME, XP, or later. • If Enabled, this device will be visible via UPnP. • If Disabled, this device will not be visible via UPnP. • If checked, then UPnP users can change the configuration. • If Disabled, UPnP users can only view the configuration. • If checked, then UPnP users can disable Internet access via this device. • If Disabled, UPnP users can NOT disable Internet access via this device. 79 Wireless Router User Guide PC Database The PC Database is used whenever you need to select a PC (e.g. for the "DMZ" PC). It eliminates the need to enter IP addresses. Also, you do not need to use fixed IP addresses on your LAN. PC Database Screen An example PC Database screen is shown below. Figure 46: PC Database • PCs which are "DHCP Clients" are automatically added to the database, and updated as required. • By default, non-Server versions of Windows act as "DHCP Clients"; this setting is called "Obtain an IP Address automatically". • The Wireless Router uses the "Hardware Address" to identify each PC, not the name or IP address. The "Hardware Address" can only change if you change the PC's network card or adapter. • This system means you do NOT need to use Fixed (static) IP addresses on your LAN. However, you can add PCs using Fixed (static) IP Addresses to the PC database if required. 80 Advanced Administration Data - PC Database Screen Known PCs This lists all current entries (PCs or network devices). Name If adding a new PC to the list, enter its name here. It is best if this matches the PC's "hostname". IP Address If adding a new PC to the list, enter the IP Address of the PC here. The PC will be sent a "ping" to determine its hardware address. If the PC is not available (not connected, or not powered On) you will not be able to add it. Buttons Add This will add the new PC to the list. The PC will be sent a "ping" to determine its hardware address. If the PC is not available (not connected, or not powered On) you will not be able to add it. Delete Delete the selected PC from the list. This should be done in 2 situations: • The PC has been removed from your LAN. • The entry is incorrect. Refresh Update the data on screen. Generate Report Display a read-only list showing full details of all entries in the PC database. Advanced Administration Click this to view the advanced "PC Database" screen. 81 Wireless Router User Guide PC Database (Admin) This screen is displayed if the "Advanced Administration" button on the PC Database is clicked.

Data displayed is name (IP Address) type. The "type" indicates whether the PC is connected to the LAN. Edit Use this to change the data for the selected PC in the list. The data for the selected PC will then be shown in the "Properties" area, where it may be edited. (Click "Update" to save any changes.) Delete Use this to Delete the selected PC from the list. This should be done in 2 situations: • The PC has been removed from your LAN. • The entry is incorrect. PC Properties Name If adding a new PC to the list, enter its name here. It is best if this matches the PC's "hostname". 82 Advanced Administration IP Address MAC Address Select the appropriate option: • Automatic - The PC is set to be a DHCP client (Windows: "Obtain an IP address automatically"). The Wireless Router will allocate an IP address to this PC when requested to do so. The IP address could change, but normally won't. • DCHP Client - Reserved IP Address - Select this if the PC is set to be a DCHP client, and you wish to guarantee that the Wireless Router will always allocate the same IP Address to this PC. Enter the required IP address. Only the last field is required; the other fields must match the Wireless Router's IP address. • Fixed IP Address - Select this if the PC is using a Fixed (Static) IP address. Enter the IP address allocated to the PC. (The PC must be configured to use this IP address.) Select the appropriate option • Automatic discovery - Select this to have the Wireless Router contact the PC and find its MAC address. This is only possible if the PC is connected to the LAN and powered On. • MAC is - Enter the MAC address on the PC. The MAC address is also called the "Hardware Address", "Physical Address", or "Network Adapter Address". The Broadband Router uses this to provide a unique identifier for each PC. Because of this, the MAC address can NOT be left blank. Buttons Add as New Entry Add a new PC to the list, using the data in the "Properties" box. If "Automatic discovery" (for MAC address) is selected, the PC will be sent a "ping" to determine its hardware address. This will fail unless the PC is connected to the LAN, and powered on. Update Selected PC Update (modify) the selected PC, using the data in the "Properties" box. Clear Form Clear the "Properties" box, ready for entering data for a new PC. Refresh Update the data on screen. Generate Report Display a read-only list showing full details of all entries in the PC database. Standard Screen Click this to view the standard PC Database screen. 83 Wireless Router User Guide Remote Administration If enabled, this feature allows you to manage the Wireless Router via the Internet. Figure 48: Remote Administration Screen Data - Remote Administration Screen Remote Administration Enable Remote Management Enable to allow management via the Internet. If Disabled, this device will ignore management connection attempts from the Internet. Port Number Enter a port number between 1024 and 65535. The default for HTTP (Web) connections is port 80, but using port 80 will prevent the use of a Web "Virtual Server" on your LAN. So using a different port number is recommended. The default value is 8080. The port number must be specified in your Browser when you connect. To specify the port number : 1. From a remote location, start your Browser. 2. In the "Address" or "Location" field, enter the Internet IP address of this device (NOT the LAN IP address), followed by the port number, as follows: http://ip_address:port_number Where: ip_address is the Internet IP address of this device. port_number is the port number assigned on this screen. 3. Current IP Address You should then be prompted for the password for this device. (You must assign a password!) To manage this device via the Internet, you need to know the IP Address of this device, as seen from the Internet. This IP Address is allocated by your ISP, and is shown here. But if using a Dynamic IP Address, this value can change each time you connect to your ISP. There are 2 solutions to this problem: • Have your ISP allocate you a Fixed IP address. • Use the DDNS feature (Advanced menu) so you can connect using a Domain Name, rather than an IP address. 84 Advanced Administration To connect from a remote PC via the Internet 1. Ensure your Internet connection is established, and start your Web Browser. 2. In the "Address" bar, enter "HTTP://" followed by the Internet IP Address of the Wireless Router. If the port number is not 80, the port number is also required. (After the IP Address, enter ":" followed by the port number.) e.g. HTTP://123.123.123.123:8080 This example assumes the WAN IP Address is 123.123.123.123, and the port number is 8080. 85 Wireless Router User Guide Routing Overview • If you don't have other Routers or Gateways on your LAN, you can ignore the "Routing" page completely. • If the Wireless Router is only acting as a Gateway for the local LAN segment, ignore the "Routing" page even if your LAN has other Routers. • If your LAN has a standard Router (e.g. Cisco) on your LAN, and the Wireless Router is to act as a Gateway for all LAN segments, enable RIP (Routing Information Protocol) and ignore the Static Routing table. • If your LAN has other Gateways and Routers, and you wish to control which LAN segments use each Gateway, do NOT enable RIP (Routing Information Protocol). Configure the Static Routing table instead. (You also need to configure the other Routers.) • If using Windows 2000 Data center Server as a software Router, enable RIP on the Broadband Router, and ensure the following Windows 2000 settings are correct: • Open Routing and Remote Access • In the console tree, select Routing and Remote Access , [server name], IP Routing, RIP • In the "Details" pane, right-click the interface you want to configure for RIP version 2, and then click "Properties". • On the "General" tab, set Outgoing packet protocol to "RIP version 2 broadcast", and Incoming packet protocol to "RIP version 1 and 2". Routing Screen The routing table is accessed by the Routing link on the Administration menu. Using this Screen Generally, you will use either RIP (Routing Information Protocol) OR the Static Routing Table, as explained above, although is it possible to use both methods simultaneously. Static Routing Table • If RIP is not used, an entry in the routing table is required for each LAN segment on your Network, other than the segment to which this device is attached. • The other Routers must also be configured. See Configuring Other Routers on your LAN later in this chapter for further details and an example. 86 Advanced Administration Figure 49: Routing Screen Data - Routing Screen RIP Enable RIP V1 Check this to enable the RIP (Routing Information Protocol) feature of the Broadband Router The Wireless Router supports RIP 1 only. Static Routing Static Routing Table Entries Properties This list shows all entries in the Routing Table. • The "Properties" area shows details of the selected item in the list. • Change any the properties as required, then click the "Update" button to save the changes to the selected entry. • Destination Network - The network address of the remote LAN segment. For standard class "C" LANs, the network address is the first 3 fields of the Destination IP Address. The 4th (last) field can be left at 0. • Network Mask - The Network Mask for the remote LAN segment. For class "C" networks, the default mask is 255.255.255.0 • Gateway IP Address - The IP Address of the Gateway or Router which the Wireless Router must use to communicate with the destination above. (NOT the router attached to the remo te segment.) • Metric - The number of "hops" (routers) to pass through to reach the remote LAN segment. The shortest path will be used. The default value is 2. Buttons Save Save the RIP setting. This has no effect on the Static Routing Table. 87 Wireless Router User Guide Add Add a new entry to the Static Routing table, using the data shown in the "Properties" area on screen. The entry selected in the list is ignored, and has no effect. Update Update the current Static Routing Table entry, using the data shown in the "Properties" area on screen. Delete Delete the current Static Routing Table entry. Clear Form Clear all data from the "Properties" area, ready for input of a new entry for the Static Routing table. Generate Report Generate a read-only list of all entries in the Static Routing table. Configuring Other Routers on your LAN It is essential that all IP packets for devices not on the local LAN be passed to the Broadband Router, so that they can be forwarded to the external LAN, WAN, or Internet. To achieve this, the local LA N must be configured to use the Wireless Router as the Default Route or Default Gateway. Local Router The local router is the Router installed on the same LAN segment as the Wireless Router. This router requires that the Default Route is the Broadband Router itself. Typically, routers have a special entry for the Default Route. It should be configured as follows. Destination IP Address Normally 0.0.0.0, but check your router documentation. Network Mask Normally 0.0.0.0, but check your router documentation. Gateway IP Address The IP Address of the Wireless Router. Metric Other Routers on the Local LAN Other routers on the local LAN must use the Wireless Router’s Local Router as the Default Route. The entries will be the same as the Wireless Router's local router, with the exception of the Gateway IP Address. • For a router with a direct connection to the Wireless Router's local Router, the Gateway IP Address is the address of the Wireless Router's local router. • For routers which must forward packets to another router before reaching the Wireless Router's local router, the Gateway IP Address is the address of the intermediate router. 88 Advanced Administration Static Routing - Example Figure 50: Routing Example For the Broadband Router's Routing Table For the LAN shown above, with 2 routers and 3 LAN segments, the Wireless Router requires 2 entries as follows. Entry 1 (Segment 1) Destination IP Address 192.168.1.0 Network Mask 255.255.255.0 (Standard Class C) Gateway IP Address 192.168.0.100 (Broadband Router's local Router) Metric Entry 2 (Segment 2) Destination IP Address 192.168.2.0 Network Mask 255.255.255.0 (Standard Class C) Gateway IP Address 192.168.0.100 Metric For Router A's Default Route Destination IP Address 0.0.0.0 Network Mask 0.0.0.0 Gateway IP Address 192.168.0.1 (Broadband Router's IP Address) For Router B's Default Route Destination IP Address 0.0.0.0 Network Mask 0.0.0.0 Gateway IP Address 192.168.1.80 (Broadband Router's local router) 89 Wireless Router User Guide Security This screen allows you to set Firewall and other security-related options. Figure 51: Security Screen Data - Security Screen DoS Firewall Enable DoS Firewall If enabled, DoS (Denial of Service) attacks will be detected and blocked. The default is enabled. It is strongly recommended that this setting be left enabled. Note: Firewall Settings Button • A DoS attack does not attempt to steal data or damage your PCs, but overloads your Internet connection so you can not use it the service is unavailable. • This device uses "Stateful Inspection" technology. This system can detect situations where individual TCP/IP packets are valid, but collectively they become a DoS attack. If you wish to adjust the settings used by the DoS firewall, click this button to o pen a sub-window. Options Respond to ICMP The ICMP protocol is used by the "ping" and "traceroute" programs, and by network monitoring and diagnostic programs. • If checked, the Wireless Router will respond to ICMP packets received from the Internet. • If not checked, ICMP packets from the Internet will be ignored. Disabling this option provides a slight increase in security. 90 Advanced Administration Allow VPN Pass through The IPSec, PPTP, and L2TP protocols are used to establish a secure connection, and are widely used by VPN (Virtual Private Networking) programs. • If checked, these VPN connections are allowed. • If not checked, these VPN connections are blocked. Note: IPSec sessions must NOT use AH (Authentication Header). Packets using AH cannot be routed correctly. Drop fragmented IP packets If enabled, fragmented IP packets are discarded, forcing retransmission of these packets. In some situations, this could prevent successful communication, so this setting is normally disabled. Block TCP Flood A TCP flood is excessively large number of TCP connection requests. This is usually a DoS (Denial of Service) attack. This setting should be normally be enabled. Block UDP Flood A UDP flood is excessively large number of UDP packets. This is often a DoS (Denial of Service) attack, but some streaming applications also use UDP, and blocking UPD packets may prevent them from working correctly. Block non-standard packets Abnormal packets are often used by hackers and in DoS attacks, but may also be generated by other network devices. (PCs will normally not generate non-standard packets.) This setting is disabled by default, but on most networks it can safely be enabled, and doing so will provide greater protection. 91 Wireless Router User Guide Upgrade Firmware The firmware (software) in the Wireless Router can be upgraded using your Web Browser. You must first download the upgrade file, then select Upgrade on the Administration menu. You will see a screen like the following. Figure 52: Upgrade Firmware Screen To perform the Firmware Upgrade: 1. Click the "Browse" button and navigate to the location of the upgrade file. 2. Select the upgrade file. Its name will appear in the Upgrade File field. 3. Click the "Start Upgrade" button to commence the firmware upgrade. The Wireless Router is unavailable during the upgrade process, and must restart when the upgrade is completed. Any connections to or through the Broadband Router will be lost. 92 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 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. General Problems Problem 1: Can't connect to the Wireless Router to configure it. Solution 1: 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 192.168.0.2 to 192.168.0.254 and thus compatible with the Wireless Router's default IP Address of 192.168.0.1. 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 u sing Control PanelNetwork 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 troubleshooting steps. Problem 2: • 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. 93 Wireless Router User Guide 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 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: • It is a security risk, since the firewall is disabled. • Only one (1) PC can use this feature. 94 Appendix B About Wireless LANs 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 Stations (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). Generally, using the same SSID is essential. Devices with different SSIDs are on different Wireless LANs, and may be unable to communicate with each other. Note that some Access Points will broadcast their SSID, allowing Wireless stations to adopt the correct SSID. This makes it easier for the clients to locate the correct AP. If the SSID is not broadcast, the client can still connect to the AP by entering the correct SSID and other data. ESS A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID), form an Extended Service Set (ESS). 95 Wireless Router User Guide 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 capabilities.) Channels The Wireless Channel sets the radio frequency used for communication. • In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent 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 signal 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 Off, 64 Bit, 128 Bit Key For 64 Bit encryption, the Key value must match. For 128 Bit encryption, the Key value must match WEP Authentication Open System or Shared Key. WPA-PSK WPA-PSK is another standard for encrypting data before it is transmitted. This is a later standard than WEP (Wired Equivalent Privacy), and provides greater security for your data. Data is encrypted using a 256Bit key which is automatically generated and changed often. If all your Wireless stations support WPA-PSK, you should use this instead of WEP. If WPA-PSK is used, the Wireless Stations and the Access Point must have the same settings for each of the following: WPA PSK (Pre-shared Key) Enter the same value on every station and the AP. The PSK must be from 8 to 63 characters in length. The 256Bit key used for the actual encryption is derived from this key. Encryption The same encryption method must be used. The most common encryption method is TKIP. Another widely96 Appendix A - Troubleshooting supported method is AES. 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.) Most Wireless stations will set the correct mode automatically. 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. Security The Wireless Stations and the Access Point must use the same settings for Wireless security. (Off, WEP, WPA-PSK). WEP: If WEP is used, the Key size (64Bit, 128Bit), Key value, and Authentication settings must be the same on the Wireless Stations and the Access Point. WPA-PSK: If WPA-PSK is used, all Wireless Stations must be set to use WPA-PSK, and have the same Pre-shared Key and encryption system. For Ad-hoc networks (no Access Point), all Wireless stations must use the same security settings. 97 Appendix C Specifications Multi-Function Wireless Router Model Wireless Router Dimensions 141mm(W) * 100mm(D) * 27mm(H) Operating Temperature 0° C to 40° C Storage Temperature -10° C to 70° C Network Protocol: TCP/IP Network Interface: 5 Ethernet: 4 * 10/100BaseT (RJ45) LAN connection 1 * 10/100BaseT (RJ45) for WAN LEDs 13 Power Adapter 12 V DC External Wireless Interface Standards IEEE802.11a/b/g WLAN, JEIDA 4.2, roaming support Frequency 2.4 to 2.4835GHz (Industrial Scientific Medical Band ) Channels Maximum 14 Channels, 1-11is allowed in USA, 1-13 in Europe Modulation DSSS BPSK/QPSK/CCK, OFDM/CCK Data Rate Up to 54 Mbps Coverage Area Indoors : 15m @54Mbps, 120m @6Mbps or lower Outdoors : 40m @54Mbps, 300m @6Mbps or lower Security WEP (64Bit/128Bit), WPA-PSK (TKIP) Output Power 18dBm (typical) Receiver Sensitivity -80dBm Min. 98 Appendix B - Specifications Regulatory Approvals FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. (Example - use only shielded interface cables when connecting to computer or peripheral devices). FCC Radiation Exposure Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The antennas used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. Channel The Wireless Channel sets the radio frequency used for communication. According to Section 15.247 on channels 1-11 between 2.4-2.4835 GHz must not have any user controls or software to allow the device to operate on channels 12 and 13 which are outside of the allowed USA band 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. 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.) 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. CAUTION: (1) To comply with FCC RF exposure compliance requirements, a separation distance of at least 20 cm must be maintained between the antenna of this device and all persons. (2) This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. (3) Frequency 5150-5250 is only used indoor. 99
