Introduction to 802.11b Wireless The IEEE 802.11b standard is the most widely used standard for wireless LANs today. A wireless LAN (WLAN) is a cellular computer network that transmits data using radio signals instead of cables. WLAN technology is commonly used on home, small office and large corporate networks. WLAN devices have a high degree of mobility and flexibility that allow networks to be quickly set up or dismantled and allow them to roam freely throughout the network.
in its broadcast range. WLAN nodes transmit digital data using FM (frequency modulation) radio signals. WLAN devices generate a carrier wave and modulate this signal using various techniques. In this way, digital data can then be superimposed onto the carrier signal. This radio signal carries data to WLAN devices within range of the transmitting device. The antennae of WLAN devices listen for and receive the signal. The signal is demodulated and the transmitted data extracted.
2 Hardware Installation The DSL-G604T functions on three separate networks: a wired Ethernet LAN, a wireless LAN and a wired ADSL WAN. Placement of the Router must take into account the fact that it is connected to these three networks with three types of media. Ethernet cables connect the Router to computers and network devices and the ADSL line connects it to a wall socket. In addition, the device must be near an AC wall outlet for power.
Power on Router CAUTION: The Router must be used with the power adapter included with the device. To power on the Router: 1. Insert the AC Power Adapter cord into the power receptacle located on the rear panel of the Router and plug the adapter into a suitable nearby power source. 2. You should see the Power LED indicator light up and remain lit. The Status LED should light solid green and begin to blink after a few seconds. 3.
Network Connections Network connections are provided through the ADSL port and the four Ethernet ports on the back of the Router. See the Rear Panel diagram above and the illustrations below for examples. Connect ADSL Line Use the ADSL cable included with the Router to connect it to a telephone wall socket or receptacle. Plug one end of the cable into the ADSL port (RJ-11 receptacle) on the rear panel of the Router and insert the other end into the RJ-11 wall socket.
Computer to Router Connection You can connect the Router directly to a 10/100BASE-TX Ethernet adapter card (NIC) installed on a PC using the Ethernet cable provided as shown in this diagram. Power On Router To power on the Router: 1. Insert the AC Power Adapter cord into the power receptacle located on the rear panel of the Router and plug the adapter into a suitable nearby power source. 2. You should see the Power LED indicator light up and remain lit.
3 Basic Router Configuration The first time you setup the Router it is recommended that you configure the WAN connection using a single computer making sure that both the computer and the Router are not connected to the LAN. Once the WAN connection is functioning properly, you may continue to make changes to Router configuration including IP settings and DHCP setup. This chapter is concerned with using your computer to configure the WAN connection.
Configure Windows XP for DHCP Use the following steps to configure a computer running Windows XP to be a DHCP client. 1. From the Start menu on your desktop, go to Settings, then click on Network Connections. 2. In the Network Connections window, right-click on LAN (Local Area Connection), then click Properties.
3. In the General tab of the Local Area Connection Properties menu, highlight Internet Protocol (TCP/IP) under “ This connection uses the following items:” by clicking on it once. Click on the Properties button. 4. Select “ Obtain an IP address automatically” by clicking once in the circle. Click the OK button. Your computer is now ready to use the Router’s DHCP server. Windows 2000 First, check for the IP protocol and, if necessary, install it: 1.
2. Double-click the Network and Dial-up Connections icon. 3. In the Network and Dial-up Connections window, right-click the Local Area Connection icon, and then select Properties. 4. The Local Area Connection Properties dialog box displays with a list of currently installed network components. If the list includes Internet Protocol (TCP/IP), then the protocol has already been enabled, skip ahead to Configure Windows 2000 for DHCP. 5.
Windows 95 and Windows 98 First, check for the IP protocol and, if necessary, install it: 1. In the Windows task bar, click the Start button, point to Settings, and then click Control Panel. Double-click the Network icon. 2. The Network dialog box displays with a list of currently installed network components. If the list includes TCP/IP, and then the protocol has already been enabled, skip to Configure IP Information Windows 95, 98. 3. If TCP/IP does not display as an installed component, click Add.
Configure Windows 95 and Windows 98 for DHCP 1. Open the Control Panel window, and then click the Network icon. 2. Select the network component labeled TCP/IP, and then click Properties. 3. If you have multiple TCP/IP listings, select the listing associated with your network card or adapter. 4. In the TCP/IP Properties dialog box, click the IP Address tab. 5. Click the Obtain an IP address automatically option. 6. Double-click OK to confirm and save your changes.
Access the Configuration Manager Now that your computer’s IP settings allow it to communicate with the Router, you can access the configuration software. Be sure that the web browser on your computer is not configured to use a proxy server in the Internet settings. In Windows Internet Explorer, you can check if a proxy server is enabled using the following procedure: 1. In Windows, click on the Start button, go to Settings and choose Control Panel. 2.
Use the default user name admin and password admin for first time setup. You should change the web-based manager access user name and password once you have verified that a connection can be established. The user name and password allows any PC within the same subnet as the Modem to access the web-based manger. Note Do not confuse the user name and password used to access the web-based manager with the ADSL account user name and password needed for PPP connections to access the service provider’s network.
Setup Menu The Setup window offers links to menus to configure settings for the LAN (Local Area Network) and for the WAN (Wide Area Network) setup. The first menu you see when clicking the Setup tab or the Go to setup wizard hyperlink is the Setup menu. Now you are ready to configure the settings needed for the WAN connection. All the information you need to make the changes needed for a functioning WAN connection should have been provided to you by your ISP or network service provider. Figure 3-3.
Wireless Settings Click the Enable AP box to allow the router to operate in the wireless environment. SSID: The SSID identifies members of Service Set. Accept the default name or change it to something else. If the default SSID is changed, all other devices on the wireless network must use the same SSID. Channel: What channels are available for use by the access point depends on the local regulatory environment.
Wireless Security The DSL-G604T offers three types of network security: WEP, 802.1X, and WPA. WEP WEP (Wireless Encryption Protocol) encryption can be enabled for security and privacy. WEP encrypts the data portion of each frame transmitted from the wireless adapter using one of the predefined keys. The router offers 64-, 128, or 256-bit encryption with four keys available. To bring up the WEP configuration window, click the WEP radio button. Figure 3-5.
802.1X Some network-security experts now recommend that wireless networks use 802.1X security measures to overcome some weaknesses in standard WEP applications. A RADIUS server is used to authenticate all potential users. Server IP Address: enter the IP address of the Radius server Port: enter a port number, or accept the default Secret: enter a password (1-63 character) Group Key Interval: time (in seconds) after which the Group Key is changed automatically (1-99999).
WPA (Wi-Fi Protected Access) Wi-Fi Protected Access was designed to provide improved data encryption, perceived as weak in WEP, and to provide user authentication, largely nonexistent in WEP. For most small networks, such as in a small business or home-based enterprise, WPA is the easiest way to obtain effective network security. Of the three options in WPA, PSK String is the easiest to implement. Figure 3-7.
Modem Setup The Modem Setup menu is used to change the Modulation Type used for the ADSL connection. This setting should only be changed if your service provider has given explicit instructions to change it. Note Do not change the (ADSL) Modulation type used unless you have been instructed to do so. If this setting is not configured properly, the Router will not work. Figure 3-8.
Figure 3- 9. PPPoA Connection 1 Setup menu To configure the default connection type (PPPoA) for Connection 1, follow the steps listed below. To change the connection type of Connection 1 to an alternative type follow the instructions according to the desired type as described below in Change the Connection Type. 1. Click the Connection 1 button under WAN Setup to view the PPPoA Connection Setup menu pictured in the example above. 2.
Change the Connection Type The default connection protocol used for the Router is Point-to-Point Protocol over ATM (PPPoA). The menu used to configure a PPPoA connection is the first menu to appear when you click on the Connection 1 button in the Setup menu. The alternative connection types supported by the Router are the PPPoE (PPP over Ethernet), CLIP (Classical IP over ATM or IPoA), DHCP (for WAN), Static (IP for WAN), and Bridge connection types.
5. If you are told to change the VPI or VCI values, type in the values given to you by your service provider. Many users will be able to use the default settings. 6. Leave the default QoS values if you are unsure or the ISP did not provide this information. 7. Do not change the PCR or SCR values unless you are required to do so. If you are told to change these, type in the values given to you by your service provider. 8. Type the Username and Password used to verify the identity of your account.
Configure Connection 1 for Bridge “ Bridge” means a pure bridged connection with no IP address assigned to the Router. This connection method makes the Router act as a bridge, and just passes packets across the DSL port. When the device is used in this manner, it is necessary to install additional connection software on any computer or server used to access the Internet. Figure 3-11. Setup – Configure Connection 1 for Bridge To configure the WAN connection for Bridge, perform the steps listed below.
9. To save the changes made to Connection 1, click the Tools tab and then click on the System Commands button. Click on the Save All button to store the configuration settings. Click on Back button to return to the System Commands menu. 10. Check the WAN connection status. Click the Status tab and then the Connection Status button. Look under WAN to view the State of Connection 1, it should read “ N/A”.
7. The Encapsulation values LLC (SNAP) and VC (MUX) are two different methods of encapsulating the PPP packet. Contact your ISP to make sure which encapsulation is being supported. 8. Based on the information provided by your ISP, enter the IP Address, Subnet Mask, Default Gateway (if provided), and Domain Name Services (DNS) values (if provided). 9. Select the desired Mode, Bridged or Routed. 10. Click the Apply button when you have entered all the information. The web browser will briefly go blank.
Configure Connection 1 for DHCP for WAN Dynamic Host Configuration Protocol (DHCP) allows the gateway to automatically obtain the IP address from a DHCP server on the service provider’s network. The service provider assigns a global IP address from a pool of addresses available to the service provider. Typically the IP address assigned has a long lease time, so it will likely be the same address each time the Router requests an IP address. Figure 3-13.
10. Check the WAN connection status. Click the Status tab and then the Connection Status button. Look under WAN to view the State of Connection 1, it should read Connected. If the WAN connection state does not appear to Connected after a few minutes, go back to the Connection 1 Setup menu, check the settings and make sure they are correct. Configure Connection 1 for CLIP CLIP or IPoA connections function in a similar way to DHCP or Static IP connections. Certain CLIP connections function like P2P networks.
9. Click the Apply button when you have entered all the information. The web browser will briefly go blank. You are now finished changing setting for the primary WAN connection known as Connection 1. It is now necessary to save the changes you just made and restart the Router. 10. To save the changes made to Connection 1, click the Tools tab and then click on the System Commands button. Click on the Save All button to store the configuration settings.
New Connection Example 2 - Create a New Bridge Connection You may create new connections to suit different purposes. For example, let’s create a new Bridge connection used to connect directly to a server acting as a firewall and proxy. 1. Click the New Connection button. 2. Select Bridge from the Type: menu. 3. Configure the remaining settings (including VPI: and VCI:) as necessary. 4. Click the Apply button. Notice that a new menu button, Connection 3, appears under WAN Setup. 5.
DHCP Configuration for LAN The Router supports three DHCP modes for the LAN. By default, DHCP service is provided using an IP pool of 192.168.1.2 – 192.168.1.254 for a total of 253 IP addresses available. The Router can also relay DHCP service from another server through the WAN port. You may prefer to disable DHCP service and DHCP relay and use a different preferred method for IP addressing on your LAN. To disable the embedded DHCP server, select the Server and Relay Off option and click the Apply button.
Enable DHCP Relay Some service providers provide DHCP service for private networks from their own servers. To enable DHCP service form outside your LAN select the DHCP Relay option and type in the server IP address in the Relay IP field. Figure 3- 18. Configure DHCP Relay Service Click the Apply button to change the DHCP Relay settings. Remember to Save All in the Tools/System Commands menu.
Management IP The IP address of the Router can be changed to suit the requirements of your LAN. Remember, if you are using DHCP from the Router, the IP address must be consistent with the DHCP IP settings. Figure 3- 19. Configure Management IP Change IP settings as desired and click the Apply button to change the DHCP Relay settings. You may also provide a Host name and Domain name if necessary for your LAN. Remember to Save All in the Tools/System Commands menu.
Save Configuration Changes Any changes made to the Router’s configuration must be saved to non-volitile memory or they will be lost if the Router is restarted or powered off. When you are finished making changes to the Router settings, follow the instructions here to save the new settings. Figure 3- 20.

4 Advanced Router Management Click the Advanced tab to access menus used to configure UPnP, Port Forwarding, Access Control, Advanced Security (including NAT, Firewall and DMZ setup), LAN Clients, Bridge Filters, Multicast passthrough, Static Routing and Dynamic Routing (RIP setup) and Wireless Management and Wireless Performance. Figure 4-1.
UPnP UPnP supports zero-configuration networking and automatic discovery for many types of networked devices. When enabled, it allows other devices that support UPnP to dynamically join a network, obtain an IP address, convey its capabilities, and learn about the presence and capabilities of other devices. DHCP and DNS service can also be used if available on the network.
LAN Clients The LAN Clients menu is used when establishing Port Forwarding, Access Control and Advanced Security rules for IP addresses on the LAN. This menu can be accessed directly by clicking on the LAN Clients button or hyperlink in the Advanced setup menu. You can also click on the New IP button located in the Port Forwarding, Access Control and Advanced Security menus to access this menu. In order to use these advanced features it is necessary to have IP addresses available for configuration.
Port Forwarding Port Forwarding allows specific functions to bypass NAT protection that would otherwise not allow them to function. To use Port Forwarding, you must have specific client IP addresses available for configuration. Use the LAN Clients menu to establish client IP addresses available for port forwarding. Note In order to use Port Forwarding, Firewall support must be enabled. See Enable/Disable NAT and Firewall in the Advanced Security menu. Figure 4-4.
You may also create customized rules to manage TCP/UDP ports. The pre-configured rules include those listed in the table here: Category Available Rules Games: Alien vs. Predator, Asheron’s Call, Dark Rein, Delta Force, Doom, Dune, DirectX Games, EliteForce, EverQuest, Fighter Ace II, Half Life, Heretic II, Hexen II, Kali, Motorhead, MSN Gaming Zone, Myth: The Fallen Lords, Need for Speed Porsche, Need for Speed 3, Outlaws, Rainbow 6, Starcraft, Tiberian Sun, Ultima, Unreal Tournament.
The User category for port forwarding is used to set up customized port forwarding rules. Figure 4- 5. Set up Custom Port Forwarding Rules To set up custom TCP or UDP port forwarding rules, follow these steps: 1. Select the User category and click the Add button located below the Available Rules list. This will change the menu to look like the example below. Figure 4- 6.

Type a number for the Port Map in the space provided. 6. Click the Apply button to create the new rule.
Access Control Access Control settings are used to block various services and protocols for specific client IP addresses. The configuration process is similar setting up port forwarding, except access control will deny specific functions to client IP addresses. There are pre-configured rules for specific functions that may be blocked or you can block specific UDP or TCP ports. Access control operates for specific IP addresses across all WAN connections.
Access Control pre-configured rules are the same as for port forwarding: Category Available Rules Games: Alien vs. Predator, Asheron’s Call, Dark Rein, Delta Force, Doom, Dune, DirectX Games, EliteForce, EverQuest, Fighter Ace II, Half Life, Heretic II, Hexen II, Kali, Motorhead, MSN Gaming Zone, Myth: The Fallen Lords, Need for Speed Porsche, Need for Speed 3, Outlaws, Rainbow 6, Starcraft, Tiberian Sun, Ultima, Unreal Tournament.
Advanced Security Use the Advanced Security features of the Router to globally enable or disable NAT and Firewall protection for any WAN connection, enable or disable DMZ IP addresses, enable or disable remote Telnet or web management from specified IP addresses, and enable/disable ICMP ping packets from the WAN. Figure 4-8. Advanced Security menu Follow the instructions below to set up the Advanced Security features.
Setup Remote Management Telnet and web management through the WAN port can be enabled for specified IP addresses. To enable remote management, click to check the selection box for Remote Telnet or Remote Web and type in an IP address and net mask of a trusted host. Bridge Filters Bridge filters are used to block or allow various types of packets through the WAN interface. This may be done for security or to improve network efficiency. The rules are configured for individual devices based on MAC address.
Multicast Pass-through Multicast pass-through can be enabled or disabled for any WAN connection. When enabled it allows IGMP packets to pass through the WAN interface. IGMP packets are used to control multicasts and discontinue multicasts to individual IP addresses when they are no longer needed. Figure 4-10. Multicast pass-through menu To enable Multicast pass through for any WAN connection, select the connection and click the Enable IGMP Multicast box to select the option, then click the Apply button.
Static Routing Use Static Routing to specify a route used for data traffic within your Ethernet LAN or to route data on the WAN. This is used to specify that all packets destined for a particular network or subnet use a predetermined gateway. Figure 4-11. Static Routing menu To add a static route, choose a connection from the pull-down menu and then enter a New Destination IP address, subnet Mask, Gateway IP address and Metric value. Click Apply to enter the new static route in the table below.
Dynamic Routing The Router supports RIP v1 and RIP v2 used to share routing tables with other Layer 3 routing devices. It also supports use of password protection which requires password verification for RIP requests. Use the Dynamic Routing menu to enable RIP and if desired to configure password protection. Figure 4-12. Dynamic Routing (RIP) menu To enable RIP v1, check Enable RIP, select RIP v1 Protocol, select the Direction (In, Out, or Both), and click Apply.
Wireless Management For added security you can opt to use Access Control based on the MAC address. This feature lets you create a list of MAC addresses that are allowed or denied association with the Router through the wireless interface. When it is enabled, the access point is instructed to forward packets only from wireless devices only if the MAC address of the device is granted association.
The remaining connection types (Bridge, Static, DHCP and CLIP) connect upon saving the settings and restarting the Router. These connections can be disconnected only if the connection set is deleted. To delete any WAN connection set, click on the Delete button in the menu for the connection.

B IP Address Setup The DSL-G604T is designed to provide network administrators maximum flexibility for IP addressing on the Ethernet LAN. The easiest IP setup choice in most cases is to let the Router do it using DHCP, which is enabled by default. This appendix briefly describes various options including DHCP, used for IP setup on a LAN. If you are new to IP networking, the next appendix provides some background information on basic IP concepts.
Router). Notice that the subnet mask is the same for all machines and the default gateway address is the LAN IP address of the Router. It is a good idea to make a note of each device’s IP address for reference during troubleshooting or when adding new stations or devices. Using DHCP The second way to use the default settings is to allow the Router to automatically assign IP settings for workstation using DHCP. To do this, simply make sure your computers’ IP addresses are set to 0.0.0.
C IP Concepts This appendix describes some basic IP concepts, the TCP/IP addressing scheme and shows how to assign IP Addresses. When setting up the Router, you must make sure it has a valid IP address. Even if you will not use the WAN port (ADSL port), you should, at the very least, make sure the Ethernet LAN port is assigned a valid IP address.

D Microfilters and Splitters Most ADSL clients will be required to install a simple device that prevents the ADSL line from interfering with regular telephone services. These devices are commonly referred to as microfilters or sometimes called (inaccurately) line splitters. They are easy to install and use standard telephone connectors and cable.
Line Splitter If you are instructed to use a “ line splitter”, you must install the device between the Modem and the phone jack. Use standard telephone cable with standard RJ-11 connectors. The splitter has three RJ-11 ports used to connect to the wall jack, the Modem and if desired, a telephone or telephone device. The connection ports are typically labeled as follows: Line - This port connects to the wall jack. ADSL – This port connects to the Modem.
