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 communica-tions. 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. •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 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 separationdistance of at least 20 cm must be maintained between the antenna of thisdevice and all persons.2) This transmitter must not be co-located or operating in conjunction withany other antenna or transmitter.

Wireless 3-in-1 Companion User Guide • Simple Configuration. If the default settings are unsuitable, they can be changed quickly and easily. Router Mode Features • DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP address to PCs and other devices upon request. The Wireless 3-in-1 Companion can act as a DHCP Server for PCs using the Access Point. • Shared LAN/WAN Access. All users on the Wireless LAN can share the IP Address on the Wireless 3-in-1 Companion's Ethernet port, providing shared access to the LAN or WAN. This process is called NAT (Network Address Translation). • Fixed or Dynamic IP Address. On the Ethernet (WAN) port connection, the Wireless 3-in-1 Companion supports both Dynamic IP Address (IP Address is allocated on connec-tion) and Fixed IP Address. • PPPoE, PPTP Support. On the Ethernet (WAN) port connection supports PPPoE (PPP over Ethernet) and PPTP (Peer-to-Peer Tunneling Protocol) login methods if required. • 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. • Port Forwarding. 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 Port For-warding on your LAN using a domain name, even if your IP address is not fixed. • DMZ. 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. • VPN Pass through Support. PCs with VPN (Virtual Private Networking) software using PPTP, L2TP and IPSec are transparently supported - no configuration is required. • Network Diagnostics. You can use the Wireless 3-in-1 Companion to perform a Ping or DNS lookup. • 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 3-in-1 Companion incorporates protection against DoS attacks.

Power Connect the supplied power adapter here. 3
Wireless 3-in-1 Companion User Guide Modes Your Wireless 3-in-1 Companion has 4 modes: • Config Mode – used for configuration only. • AP (Access Point) Mode. • AP/Router Mode – both AP and Router. • Client Mode - the Wireless 3-in-1 Companion is connected to your PC's Ethernet port, and converts that port to a Wireless interface. You PC can then use the Wireless 3-in-1 Com-panion to join a Wireless network. The mode is set ONLY by the mode selector switch on the side of the Wireless 3-in-1 Com-panion. (You will need to wait a few seconds after changing modes.) It is important to understand these different modes, and the benefits and limitations of each. Config Mode Use this mode to any perform any required configuration. In Config mode, the following settings are always used. Password The current password is used. The Default password is blank. If the password is set, you must use admin as the login name. IP address 192.168.0.1 (Mask: 255.255.255.0) DHCP Server Enabled (for both Ethernet & Wireless) SSID default Wireless Security Disabled You can connect to the Wireless 3-in-1 Companion using either the Wireless interface or the wired Ethernet connection. Using the Wired connection is recommended. See the later section Initial Configuration for details. 4
Introduction Access Point Mode The Wireless 3-in-1 Companion connects Wireless stations to each other, and to the LAN on the Ethernet port. Because the Wireless 3-in-1 Companion is “transparent” (does not have an IP address) you cannot configure it while in AP mode. Q. When Should I use Access Point (AP) Mode? Ans. Use this mode in any of these situations: • You are the ONLY user (wireless client). • There are multiple wireless clients, and you have explicit permission for all users to con-nect to the LAN or WAN to which the Ethernet port is connected. • You want to create a private Wireless LAN (not using the Ethernet port), using Infrastruc-ture mode instead of Ad-hoc mode. In this case, each PC must "self-assign" an IP address, since there is no DHCP Server available. If using Windows XP, this self-assignment will work correctly; all wireless stations will have compatible IP addresses. Q. When Shouldn't I use Access Point (AP) Mode? Ans. Do NOT use this mode in this situation: • There are multiple users (wireless clients). • You do NOT have permission for all of these users to connect to the LAN or WAN on the Ethernet port. In this situation, you should use AP/Router mode. 5
Wireless 3-in-1 Companion User Guide AP/Router Mode In AP/Router Mode, the Wireless 3-in-1 Companion acts as an AP and a DHCP Server, allocating IP addresses for Wireless stations (clients). It also acts as a NAT Router, sharing the IP address on the Ethernet (LAN/WAN) port with all Wireless clients. (It has 2 IP addresses, one on the LAN/WAN port and another on the Wireless LAN.) When Should I use AP/Router Mode? Use this mode in any of these situations: • The Ethernet port is connected to a Broadband modem rather than an Ethernet port. • You have permission for ONLY ONE (1) user to connect to the LAN or WAN, but you need to connect multiple users. (In AP/Router mode, the IP address on the Ethernet port is shared by all Wireless clients.) Q. When Shouldn't I use AP/Router Mode? Ans. You can always use AP/Router mode to establish a wireless connection to the LAN or WAN. However, this mode uses a technology called "NAPT" (Network Address Port Translation), and NAPT may cause problems with some complex multi-user communication applications. (There is no problem with common services such as HTTP, FTP, E-mail, etc.) If you have problems, you should try getting permission for all users to connect to the LAN/WAN, so you can use AP mode instead. Note: You can connect to the Wireless 3-in-1 Companion, and change its configuration, while it is AP/Router Mode. The IP address used is the "Wireless LAN" IP address, which can be set on the AP/Router setup screen. The default value is 192.168.0.1 (the same as the Config Mode IP address), but you can change this if you wish. You MUST change the Wireless LAN IP address if the LAN/WAN is using the address range 192.168.0.1 ~ 192.168.0.254. 6
Introduction Client Mode In Client mode, the Wireless 3-in-1 Companion is connected to the Ethernet port of your PC (or other device), and will connect to a Wireless LAN. This has the effect of converting the Ethernet port to a Wireless interface. Note that in client mode, the Wireless 3-in-1 Companion is transparent; it has no IP address. Q. When Should I use Client Mode? Ans. Use this mode in any of these situations: • Your PC does not have a wireless interface. • The wireless interface on your PC does not support the features you need. • You wish to connect to two (2) Wireless networks simultaneously - one via your wireless interface, the other via the Ethernet port and the Wireless 3-in-1 Companion. 7

5 Chapter 5 AP/Router Mode - Advanced Features This Chapter explains when and how to use the Wireless 3-in-1 Companion's "Advanced" Features in AP/Router mode Overview The following advanced features are provided in AP/Router mode. • Advanced Internet • Communication Applications • DMZ • Port Forwarding • Dynamic DNS • Network Diagnostics • Option • PC Database • Security These features are accessed via the Advanced button on the AP/Router Setup screen. 40
PC Configuration Advanced Internet Screen This screen allows configuration of all advanced features relating to Internet access. • Communication Applications • DMZ • MTU (Maximum Transmission Unit) An example screen is shown below. Figure 19: Internet Screen Communication Applications Most applications are supported transparently by the Wireless 3-in-1 Companion. But some-times it is not clear which PC should receive an incoming connection. This problem could arise with the Communication Applications listed on this screen. If this problem arises, you can use this screen to set which PC should receive an incoming connection, as described below. Communication Applications Application This lists applications which may generate incoming connec-tions, where the destination PC (on your local LAN) is unknown. For each application, you can select the PC to which incoming connections may be sent. Send incoming calls .. This lists the PCs on your wireless LAN. • For each application listed above, you can choose a destina-tion PC. • If necessary, you can add PCs manually, using the "PC Database" menu option. • There is no need to "Save" after each change; you can set the destination PC for each application, then "Save". 41
Wireless 3-in-1 Companion User Guide DMZ Enable DMZ… Use this to enable the DMZ feature as required. • 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. DMZ PC If the DMZ feature is enabled, you must select a PC. If the PC uses a fixed IP address, and is not in the list, you can add it using the "PC Database" menu option. MTU MTU size MTU (Maximum Transmission Unit) determines the size of network packets. This 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. 42
PC Configuration Port Forwarding This feature, sometimes called Virtual Servers, 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 "Port Forwarding" feature solves these problems and allows Internet users to connect to your servers, as illustrated below. Figure 20: Port Forwarding 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 Port Forwarding using a URL, instead of an IP Address. 43
Wireless 3-in-1 Companion User Guide Port Forwarding Screen The Port Forwarding screen is reached by the Port Forwarding link. An example screen is shown below. Figure 21: Port Forwarding 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 - Port Forwarding Screen Service Service This lists a number of pre-defined Services, plus any Services you have defined. Details of the selected Service are shown in the "Properties" area.. Properties Enable Use this to Enable/Disable Port Forwarding for this Service, as required. PC (Server) Select the PC to be used as the Server for this Service. The PC must be running the appropriate Server software. Protocol Select the protocol (TCP, UDP or TCP/UDP) used by the Service. Internal Ports Enter the range of port numbers which the Server software is configured to use. External Ports Traffic from the Internet using this range of port numbers will be sent to the selected Server. These ports are normally the same as the Internal Port Numbers. If they are different, this device will perform a "mapping" or "translation" function, allowing the server to use a different port range to the clients. Using this feature allows the server to distinguish traffic from the WAN from traffic on the local LAN by using the port number, rather than having to check IP addresses. 44
PC Configuration Buttons Defaults This will delete any Servers you have defined, and set the pre-defined Servers to use their default port numbers. Disable All This will cause the "Enable" setting of all entries to be set OFF. Update Selected Server Update the current entry, using the data shown in the "Properties" area on screen. Add as new Server Add a new entry to the 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 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 entry. For each entry, the PC must be running the appropriate Server software. Defining your own Servers If the type of Server you wish to use is not listed on the Port Forwarding screen, you can define and manage your own Servers: Create a new 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. Modify (Edit) a Server: 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. Delete a Server: 1. Select the entry from the list. 2. Click "Delete". Note: You can only delete Servers you have defined. Pre-defined Server cannot be deleted. From the WAN or Internet, ALL Port Forwarding have the same IP Address - the IP address assigned to the WAN port. 45
Wireless 3-in-1 Companion User Guide Connecting to your Servers Once configured, anyone on the WAN or Internet can connect to your Servers. They must use the WAN (Internet) IP Address: e.g. http://203.70.212.52 ftp://203.70.212.52 It is more convenient if you are using a Fixed IP Address, rather than Dynamic. However, you can use the Dynamic DNS feature, described in the following section, to allow users to connect to your Port Forwarding using a URL, rather than an IP Address. 46
PC Configuration Dynamic DNS (Domain Name Server) This free service is very useful when combined with the Port Forwarding feature. It allows Internet users to connect to your 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 3-in-1 Companion's DDNS screen. 4. The Wireless 3-in-1 Companion 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 servers (or DMZ PC) using your Domain Name. Dynamic DNS Screen Select DDNS to see a screen like the following: Figure 22: DDNS Screen Data - Dynamic DNS Screen DDNS Service DDNS Service • Select the desired DDNS Service Provider from the list. You must register for the service at one of the listed Service Provid-ers. You can reach the Service provider's Web Site by selecting them in the list and clicking the "Web Site" button. • Apply for a Domain Name, and ensure it is allocated to you. • Details of your DDNS account (Name, password, Domain name) must then be entered and saved on this screen. • This device will then automatically ensure that your current IP 47
Wireless 3-in-1 Companion User Guide Address is recorded by the DDNS Service Provider. (You do NOT need to use the "Client" program provided by some DDNS Service providers.) • From the Internet, users will now be able to connect to your Servers (as defined by your Port Forwarding setup) or DMZ PC using your Domain name. Web Site Button Click this button to open another browser window and connect to the Web site of the selected DDNS service provider. DDNS Status • This message is returned by the DDNS Server • Normally, this message should be "Update successful" • If the message is "No host" or some other error message, you need to connect to the DDNS Service provider and correct the problem. DDNS Data User Name Enter your Username for the DDNS Service. Password/Key Enter your current password for the DDNS Service. Domain Name Enter the domain name allocated to you by the DDNS Service.

PC Configuration PC Database The PC Database is used whenever you need to select a PC (e.g. for the "DMZ" PC). It elimi-nates the need to enter IP addresses. Also, you do not need to use fixed IP addresses on your Wireless LAN. PC Database Screen An example PC Database screen is shown below. Figure 25: 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 3-in-1 Companion 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 re-quired. 51
Wireless 3-in-1 Companion User Guide Data - PC Database Screen Known PCs This lists all current entries. Data displayed is name (IP Address) type. The "type" indicates whether the PC is connected to the LAN. 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 Enter the IP Address of the PC. The PC will be sent a "ping" to deter-mine 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 con-nected, 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 situa-tions: • The PC has been removed from your LAN. • The entry is incorrect. Refresh Update the data on screen. Advanced View the Advanced version of the PC database screen, which provides some additional options. See below for details. 52

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". 53
Wireless 3-in-1 Companion User Guide IP Address Select the appropriate option: • Automatic - The PC is set to be a DHCP client (Windows: "Ob-tain an IP address automatically"). The Wireless 3-in-1 Companion 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 3-in-1 Companion 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 3-in-1 Companion's IP ad-dress. • 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.) MAC Address Select the appropriate option • Automatic discovery - Select this to have the Wireless 3-in-1 Companion contact the PC and find its MAC address. This is only possible if the PC is connected to the LAN and powered On. • MAC address is - Enter the MAC address on the PC. The MAC address is also called the "Hardware Address", "Physical Ad-dress", or "Network Adapter Address". The Wireless 3-in-1 Companion 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.

PC Configuration Security This screen allows you to set Firewall and other security-related options. Figure 27: Security Screen Data - Security Screen 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: • 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. Threshold This setting affects the number of "half-open" connections allowed. • A "half-open" connection arises when a remote client contacts the Server with a connection request, but then does not reply to the Server's response. • While the optimum number of "half-open" connections allowed (the "Threshold") depends on many factors, the most important factor is the available bandwidth of your Internet connection. • Select the setting to match the bandwidth of your Internet connec-tion. 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 3-in-1 Companion will respond to ICMP packets received via the WAN port. • If not checked, ICMP packets from the WAN port will be ignored. Disabling this option provides a slight increase in security. 55
Wireless 3-in-1 Companion User Guide Allow IPsec The IPSec protocol is used to establish a secure connection, and is widely used by VPN (Virtual Private Networking) programs. • If checked, IPSec connections from the Wireless LAN are al-lowed. • If not checked, IPSec connections are blocked. Allow PPTP PPTP (Point to Point Tunneling Protocol) is widely used by VPN (Virtual Private Networking) programs. • If checked, PPTP connections from the Wireless LAN are al-lowed. • If not checked, PPTP connections are blocked. Allow L2TP L2TP is a protocol developed by Cisco for VPNs (Virtual Private Networks). • If checked, L2TP connections from the Wireless LAN are al-lowed. • If not checked, L2TP connections are blocked. 56
6 Chapter 6 Setup - Client Mode This Chapter details configuration for Client Mode. Overview You can NOT connect to the Wireless 3-in-1 Companion while it is in Client mode. Configu-ration for Client mode must be performed while in Config Mode. Connecting 1. Use the mode selector switch on the side on the Wireless 3-in-1 Companion to select "Config" mode. 2. Power up and wait for the Wireless LED to turn on. This indicates the Wireless 3-in-1 Companion is ready. 3. Establish a Wired or Wireless connection to the 3-in-1. • Wired - connect a standard LAN cable from your PC's 10/100BaseT Ethernet port to the Ethernet port on the Wireless 3-in-1 Companion. • Wireless - select the wireless network with the SSID default 4. Start your Web browser. 5. In the "Location" or "Address" bar, enter the following: config.ap Note: This will work only while in Config mode. 6. If the admin password has been set (on the System screen), you will be prompted for the username and password. • Enter admin for the user name. • Enter the current password. 7. You will then see the Mode Configuration screen. Click the "Config" button for Client Mode, to view the Client Setup screen. 57
Wireless 3-in-1 Companion User Guide Client Mode Setup The screen for Client Mode is reached by clicking the "Config" button for Client Mode on the Mode Configuration screen. In client mode, you can create a Profile for each Wireless network you use regularly. • A "Profile" contains all settings for the Wireless network, including the security settings. • Only one (1) Profile can be enabled at any time. • If the Wireless network defined by the currently-enabled profile is not available, then no wireless connection will be made. Client Mode Setup Screen Figure 28: Client Mode Setup Screen Data - Client Mode Setup Screen Wireless Profiles All available profiles are listed. For each profile, the following data is displayed: • * If a * is displayed before the name of the profile, this indicates the profile is the current profile (it is enabled). • Profile Name The current profile name is displayed. • [SSID] The current SSID associated with this profile. • Type The network type - Auto, Ad Hoc, or Infrastructure. • Security The current security system (e.g. WEP ) is displayed. 58
PC Configuration Buttons • Set as Current - Make the selected profile the current profile. The selected profile will be enabled, and all other profiles wil be disabled. • Add - Create a new Profile. This will display the • Edit - Change the settings for the selected profile. • Delete - Delete the selected profile. Wireless Client Profile Screen This screen is displayed when the Add or Edit button on the Client Mode Setup screen is clicked. Figure 29: Wireless Client Profile Data - Wireless Client Profile General Profile Name Enter a suitable name for this profile. Each profile must have a unique name. Network Type Select the desired option: • Auto - this device will attempt to join a Wireless network with the same SSID, regardless of whether the network is using Infra-structure mode or Ad hoc mode. • Ad Hoc - only an Ad Hoc network will be used; Infrastructure networks will be ignored. • Infrastructure - only an Infrastructure network will be used; Ad hoc networks will be ignored. 59
Wireless 3-in-1 Companion User Guide SSID Enter the SSID of the wireless network you wish to join. • If Infrastructure mode, this may be left blank; this device will then join any wireless network it can. This is only possible if the Access Point is broadcasting its SSID, and the security settings for this profile match the security set-tings on the Access Point. • If more than one Access Point is available with this profile, the one with the strongest signal will be used. 802.11 mode Select the desired option: • Auto - This station will auto-select the correct mode to allow communication. • 802.11b - Only a 802.11b connection will be used. • 802.11g - Only a 802.11g connection will be used. Channel No. This field determines which operating frequency will be used. • If the network type is "Auto" or "Infrastructure", only the "Auto" channel selection is available, because this station must use the Channel used by the Wireless network it is joining. • For Ad-hoc mode, you can set the Channel to use. But to join an existing Wireless network, this station must adopt the Channel al-ready in use, so this setting is only meaningful when creating a new Wireless network. Security Security Select the desired option, and then enter the settings for the selected method: • Disabled - No security is used. Data is not encrypted before transmission. • WEP The 802.11b standard. Data is encrypted before transmission. You have 2 options: • WEP 64 Bit - this uses 64 bit encryption. You must enter the WEP key (10 Hex characters). • WEP 128 Bit - this uses 128 bit encryption. You must enter the WEP key (26 Hex characters). • WPA-PSK Like WEP, data is encrypted before transmission. WPA-PSK is a later standard than WEP, and provides better security. If all your Wireless stations support WPA-PSK, you should use this rather than WEP. Note: WPA-PSK is only available in Infrastructure mode. WEP Authentication Normally this can be left at the default value of "Automatic." If that fails, select the appropriate value - "Open System" or "Shared Key." Check your wireless card's documentation to see what method to use. 60
PC Configuration WEP Key • Enter the key value you wish to use. Other stations must have the same key value. • In "Infrastructure" mode, this key must match the "Default Key" value on the Access Point. • Keys must be entered in Hex. Hex characters are the digits ( 0 ~ 9 ) and the letters A ~ F. WEP Key Index This is only useful in Infrastructure mode. It is possible for an Access Point to have more than one (1) key, but only one can be the "default key". This index must be set to match the "default key" index on the Access Point. Normally, this is one (1). Passphrase Use this to generate a Hex key from an ASCII string. Enter a word or group of printable (ASCII) characters in the Passphrase box and click the "Generate" button to generate the WEP Key. WPA - PSK PSK Enter the PSK (Pre-shared Key), sometimes the network key, used on the Access Point. WPA Encryption This must match the Encryption method used on the Access Point. 61
7 Chapter 7 Operation and Usage This Chapter details the operation of the Wireless 3-in-1 Companion and the status screens. Overview The mode can be changed ONLY by using the Mode switch on the side of the Wireless 3-in-1 Companion. This switch has 4 positions: 1. AP Mode 2. AP/Router Mode 3. Config Mode 4. Reserved Set Chapter 1 for details about each mode, and some tips on which mode to use in different environments. Changing Modes While you can change modes at any time, please pay attention to the following points: • Whenever the mode is changed, the Wireless 3-in-1 Companion will restart. You need to wait for the restart to be completed, which will take a few seconds. When the restart is completed, the Wireless LED will be ON. • After changing modes, any Wireless connections will be lost. On your PC, you need to select the SSID (Wireless LAN) for the new mode in order to re-establish a Wireless con-nection to the Wireless 3-in-1 Companion. Using AP Mode 1. Use a standard LAN cable to connect the Ethernet port on the Wireless 3-in-1 Companion to the desired LAN. 2. Use the mode selector switch on the side on the Wireless 3-in-1 Companion to select "AP" mode. 3. Wait for the restart to be completed, and the Wireless LED to come On. 4. On your PC, select the wireless LAN matching the SSID of the Wireless 3-in-1 Compan-ion in AP mode. The default SSID for AP mode is default_AP 5. If necessary, configure your PC's wireless interface to match the settings of the Wireless 3-in-1 Companion's AP mode. 6. You should then be able to connect to the LAN via the Wireless 3-in-1 Companion. • You can check the status of your PC's wireless interface to see that your PC has ob-tained an IP address. • This IP address must come from a server on the LAN; the Wireless 3-in-1 Companion itself is transparent. 62
Advanced Administration If the Ethernet port is not connected to a functional LAN, then your PC will "self-assign" an IP address. Using AP/Router Mode 1. Use a standard LAN cable to connect the Ethernet port to the desired LAN or WAN. Note: To avoid potential problems, you should NOT change the LAN/WAN connection from the Wireless 3-in-1 Companion to your PC, or vice versa. Doing so may cause the connection to fail. 2. Use the mode selector switch on the side on the Wireless 3-in-1 Companion to select "AP/Router" mode. 3. Wait for the restart to be completed, and the Wireless LED to turn On. 4. On your PC, select the wireless LAN matching the SSID of the Wireless 3-in-1 Compan-ion in AP/Router mode. • The default SSID for AP/Router mode is default_Router • If necessary, configure your PC's wireless interface to match the settings of the Wire-less 3-in-1 Companion's AP/Router mode. • You can check the status of your PC's wireless interface to see that your PC has ob-tained an IP address. If it has, then the Wireless connection to the Wireless 3-in-1 Companion is working correctly. 5. You should now be able to access the LAN or WAN. If you can't, you can connect to the Wireless 3-in-1 Companion (while still in AP/Router mode) to check its status and configuration. Connecting in AP/Router Mode 1. Start your Web browser 2. In the "Location" or "Address", enter "HTTP://" and the current IP address for the Wire-less LAN, as set on the AP/Router screen. The default value is 192.168.0.1: HTTP://192.168.0.1 3. If the password has been set (by default, it is blank), you will be prompted for the user-name and password. • Enter admin for the user name. • Enter the current password. 4. You will then see the Mode Configuration screen. Click the "Configure" button for AP/Router Mode. You will see a screen like the following. 63
Wireless 3-in-1 Companion User Guide Figure 30: AP/Router Setup (Annotated) 5. Check the Ethernet (WAN) port status and settings. • If the Wireless 3-in-1 Companion has not obtained a valid IP address, click the "Con-figure" button and change the settings as required. Check with the LAN administrator if necessary, to determine the correct settings. • If the LAN/WAN is using the same IP address range as the Wireless LAN, you need to change the Wireless LAN AP/Router IP address to use a different address range. • If the connection is working, but some applications do not function correctly, you may need to change some "Advanced" settings. See Chapter 5 for details of the "Ad-vanced" settings. 64
Advanced Administration Using Client Mode In client mode, the Wireless 3-in-1 Companion's Ethernet port must be connected to your PC's Ethernet port. Before using client mode, ensure that the Client Mode configuration is correct. • Configuration must be performed in Config mode. Admin connections are not possible while in Client mode. • See Chapter 6 for details of Client mode setup. If the configuration is correct, the procedure for using client mode is as follows: 1. Use a standard LAN cable to connect the Ethernet port on the Wireless 3-in-1 Companion to your PC. 2. Use the mode selector switch on the side on the Wireless 3-in-1 Companion to select "Client" mode. 3. Wait for the restart to be completed, and the Wireless LED to come On. 4. The Wireless 3-in-1 Companion will then connect, if possible, to the Wireless LAN specified by the current Client Profile. • You cannot connect to the Wireless 3-in-1 Companion while in Client Mode. You must specify the desired Wireless LAN using Config mode. • In Client Mode, the Wireless 3-in-1 Companion is transparent; it does not have an IP address. 5. You can check the "Properties" of your PC's Ethernet connection to see if it has obtained a valid IP address: • If using Infrastructure mode (connecting to an Access Point), the IP address must be a valid IP address on the LAN to which the Access Point is connected. • If using Ad-hoc mode, the IP address should be self-assigned ("Auto-configuration"). If other PCs in the Ad-hoc Wireless LAN behave the same way, everyone will have compatible IP addresses. 65
A 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 3-in-1 Companion and some possible solutions to them. If you follow the suggested steps and the Wireless 3-in-1 Companion still does not function properly, contact your dealer for further advice. General Problems Problem 1: Can't connect to the Wireless 3-in-1 Companion to configure it. Solution 1: Try using the wired Ethernet connection and the Wireless 3-in-1 Compan-ion's IP address. 1. Connect a LAN cable from the Wireless 3-in-1 Companion to the Ethernet port on your PC. 2. Set the Wireless 3-in-1 Companion to "Config" mode. 3. Restart the Wireless 3-in-1 Companion. 4. Restart your PC. (Or, if you know how to do so, you could perform a "Release" and "Renew" of the IP address on the Ethernet port.) 5. Start your Web browser. 6. Enter the Address as: HTTP://192.168.0.1 Wireless Access - AP or AP/Router Mode Problem 1: My PC can't locate the Wireless Access Point. Solution 1: • Check the "Broadcast SSID" setting. Has it been disabled? If it has, the AP will not be listed in "Available Wireless Networks", and you will have to configure your PC manually. If using manual configuration, en-sure the mode is Infrastructure and not Ad-hoc. • To see if radio interference is causing a problem, see if connection is possible when close to the Wireless 3-in-1 Companion. Remember that the connection range can be as little as 50 feet in poor environments. Problem 2: On my PC, I can locate the Wireless 3-in-1 Companion, but I can't establish a connection. Solution 2: • The SSID on your PC and the Wireless Access Point must be the same. Remember that the SSID is case-sensitive. So, for example "Work-group" does NOT match "workgroup". • Both your PC and the Wireless 3-in-1 Companion must have the same settings for Wireless security. The default setting for the Wireless 3-in-66
Appendix A - Troubleshooting 1 Companion is disabled, so your wireless station should also have Wireless security disabled. If Wireless security is enabled on the Wireless 3-in-1 Companion, Wireless stations must use the same settings as the Wireless 3-in-1 Companion. • If the Wireless 3-in-1 Companion is set to Allow Trusted Stations only, then each of your Wireless stations must be in the Trusted Wireless Sta-tions list, or access will be blocked. Problem 3: Wireless connection speed is very slow. Solution 3: The wireless system will connect at the highest possible speed, depending on the distance and the environment. To obtain the highest possible connec-tion speed, you can experiment with the following: • Wireless 3-in-1 Companion location. Try adjusting the location and orientation of the Wireless 3-in-1 Com-panion. • 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 3-in-1 Companion. 67
Wireless 3-in-1 Companion User Guide Router Mode 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. • 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 3-in-1 Companion. Ensure that it is connected and ON. Con-nect to it and check its settings. (If you can't connect to it, check the LAN and power connections.) • If the Wireless 3-in-1 Companion is configured correctly, check your Internet connection (DSL/Cable modem etc) to see that it is working correctly. Problem 2: Some applications do not run properly when using the Wireless 3-in-1 Companion. Solution 2: The Wireless 3-in-1 Companion 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. 68
B 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 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.) 69
Wireless 3-in-1 Companion User Guide 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 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. 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.) 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. WEP 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"). 70
