Figure 3-1 Hardware Installation of the TL-R402M Cable/DSL Router
Chapter 4. Quick Installation Guide
After connecting the TL-R402M router into your network, you should configure it. This chapter describes how to configure the basic functions of your TL-R402M Cable/DSL Router. These procedures only take you a few minutes. You can access the Internet via the router immediately after it has been successfully configured.

4.1 TCP/IP configuration

The default IP address of the TL-R402M Cable/DSL Router is 192.168.1.1, and the default Subnet Mask is 255.255.255.0. These values can be seen from the LAN, and can be changed as your desire. As an example, we use the default values for description in this guide. Connect the local PCs to the LAN ports on the router. There are then two means to configure the IP address for your PCs. Configure the IP address manually (Recommended) 1) Set up the TCP/IP Protocol for your PC(s). 2) Configure the network parameters. The IP address is 192.168.1.xxx ("xxx" is from 2 to 254), Subnet Mask is 255.255.255.0, and Gateway is 192.168.1.1 (The router's default IP address) Obtain an IP address automatically 1) Set up the TCP/IP Protocol in "Obtain an IP address automatically" mode on your PC(s). 2) Power off the router and PC(s). Then turn on the router, and restart the PC(s). The built-in DHCP server will assign IP addresses for the PC(s). Note: If you need instructions as to how to do this, please refer to Appendix B: "Configuring the PCs." Now, you can run the Ping command in the command prompt to verify the network connection between your PC(s) and the router. The following example is in Windows 2000. Open a command prompt, and type ping 192.168.1.1, and then press Enter.
Figure 4-1 Successful result of Ping command If the result displayed is similar to what is shown in Figure 4-1, the connection between your PC and the router has been established.
Figure 4-2 Failed result of Ping command If the result displayed is similar to what shown in Figure 4-2 it means that your PC has not connected to the router. If so, refer to the following steps for a solution. 1 Is the connection between your PC and the router correct? Note: The Link/Act LEDs of LAN port on the router and LEDs on your PC's adapter should be lit. 2 Is the TCP/IP configuration for your PC correct? Note: If the router's IP address is 192.168.1.1, your PC's IP address must be within the range of 192.168.1.2 ~ 192.168.1.254, the gateway must be 192.168.1.1.

5.4.1 LAN

You can configure the IP parameters of the LAN on this page.
Figure 5-3 LAN MAC Address - The physical address of the router, as seen from the LAN. The value can't be changed IP Address - Enter the IP address of your router in dotted-decimal notation (factory default: 192.168.1.1) Subnet Mask - An address code that determines the size of the network. Normally use 255.255.255.0 as the subnet mask Note: 1. If you change the IP address of the LAN, you must use the new IP address to login to the router. 2. If the new LAN IP Address you set is not in the same subnet, the IP Address pool in the DHCP sever will not take effect, until they are re-configured. 3. If the new LAN IP Address you set is not in the same subnet, the Virtual Server and DMZ Host may change accordingly at the same time, youd better re-configure it as well.

5.4.2 WAN

You can configure the WAN port parameters on this page. First, please choose the WAN Connection Type (Dynamic IP/Static IP/PPPoE/L2TP) to the Internet. The default type is PPPoE. If you arent given any login parameters (fixed IP address, logging ID, etc), please select Dynamic IP. If you are given a fixed IP (static IP), please select Static IP. If you are given a user name and a password, please select PPPoE. If your ISP provides L2TP connection, please select L2TP option. If you are not sure which connection type you use currently, please contact your ISP with the correct information. 1. If you choose Dynamic IP, the router will automatically get IP parameters from your ISP. You can see the page as follows (Figure 5-4):
Figure 5-4 WAN - Dynamic IP This page displays the WAN IP parameters assigned dynamically by your ISP, including IP address, Subnet Mask, Default Gateway, etc. Click the Renew button to renew the IP parameters from your ISP. Click the Release button to release the IP parameters. MTU Size: The normal MTU (Maximum Transmission Unit) value for most Ethernet networks is 1500 Bytes. For some ISPs you need to reduce the MTU. But this is rarely required, and should not be done unless you are sure it is necessary for your ISP connection If your ISP gives you one or two DNS addresses, select Use These DNS Servers and enter the primary and secondary addresses into the correct fields. Otherwise, the DNS servers will be assigned dynamically from ISP Get IP with Unicast DHCP: A few ISPs' DHCP servers do not support the broadcast applications. If you cannot get the IP address normally, you can choose this option. (You generally need not check this option) Note: If you get Address not found errors when you go to a Web site, it is likely that your DNS servers are set up improperly. You should contact your ISP to get DNS server addresses. 2. If you choose Static IP, you should have fixed IP parameters specified by your ISP. The Static IP settings page will appear, shown in Figure 5-5:

Figure 5-5 WAN - Static IP You should type the following parameters into the spaces provided: IP Address - Enter the IP address in dotted-decimal notation provided by your ISP Subnet Mask - Enter the subnet Mask in dotted-decimal notation provided by your ISP, usually is 255.255.255.0 Default Gateway: (Optional) Enter the gateway IP address in dotted-decimal notation provided by your ISP MTU Size - The normal MTU (Maximum Transmission Unit) value for most Ethernet networks is 1500 Bytes. For some ISPs you may need to modify the MTU. But this is rarely required, and should not be done unless you are sure it is necessary for your ISP connection Primary DNS - (Optional) Type the DNS address in dotted-decimal notation provided by your ISP Secondary DNS - (Optional) Type another DNS address in dotted-decimal notation provided by your ISP if provided 3. If you choose PPPoE, you should enter the following parameters (Figure 5-6):

If you wish to activate Connect on Demand, click the radio button. If you want your Internet connection to remain active at all times, enter 0 in the Max Idle Time field. Otherwise, enter the number of minutes you want to have elapsed before your Internet connection terminates. Caution: Sometimes the connection cannot be disconnected although you specify a time to Max Idle Time. This is because there may still be active applications in the background, which may cause fee accounted by your ISP. Connect Automatically - Connect automatically after the router is disconnected. To use this option, click the radio button Connect Manually - You can configure the router to make it connect or disconnect manually. After a specified period of inactivity (Max Idle Time), the router will disconnect your Internet connection, and not be able to re-establish your connection automatically as soon as you attempt to access the Internet again. To use this option, click the radio button. If you want your Internet connection to remain active at all times, enter 0 in the Max Idle Time field. Otherwise, enter the number in minutes that you wish to have the Internet connecting last unless a new link is requested Caution: Sometimes the connection cannot be disconnected although you specify a time to Max Idle Time. This is because there may still be active applications in the background, which may cause fee accounted by your ISP. Click the Connect button to connect immediately, Click the Disconnect button to disconnect immediately. Click the Advanced Settings button to set up the advanced option, the page shown in Figure 5-7 will then appear:

5.6 Forwarding

- Forwarding Virtual Servers Port Triggering DMZ UPnP Figure 5-14 the Forwarding menu There are four submenus under the Forwarding menu (shown in Figure 5-14): Virtual Servers, Port Triggering, DMZ and UPnP. Click any of them, and you will be able to configure the corresponding function. The detailed explanations for each submenu are provided below.

5.6.1 Virtual Servers

Virtual servers can be used for setting up public services on your LAN, such as DNS, Email and FTP. A virtual server is defined as a service port, and all requests from Internet to this service port will be redirected to the computer specified by the server IP. Any PC that was used for a virtual server must have a static or reserved IP address because its IP address may change when using the DHCP function. You can set up virtual servers on this page, shown in Figure 5-15:
Figure 5-15 Virtual Servers Service Port - The numbers of External Ports. You can type a service port or a range of service ports (the format is XXX YYY, XXX is Start port, YYY is End port) IP Address - The IP address of the PC running the service application Protocol - The protocol used for this application, either TCP, UDP, or All (all protocols supported by the router) Enable - The Enable checkbox to enable the virtual server entry Common Service Port - Some common services already listed in the pull-down list 25
To setup a virtual server entry: 1. Select the service you want to use from the Common Service Port list, select the ID you want to use, and click the Copy to button. If the Common Service Port list does not have the service that you want to use, type the number of the service port or service port range in 2. 3. 4. 5. the Service Port box. Type the IP address of the computer in the Server IP Address box. Select the protocol used for this application, either TCP,UDP, or All. Select the Enable checkbox to enable the virtual server. Click the Save button.
Note: It is possible that you have a computer or server that has more than one type of available service. If so, select another service, and enter the same IP address for that computer or server. To modify a virtual server entry: 1. Select the entry you want to modify 2. 3. Modify the information from the Service Port, the IP Address boxes, and the Protocol pull-down list. Click the Save button.
To delete a service entry: 1. 2. Clear the entry's all information except for the Protocol pull-down list. Click the Save button.
To delete all service entries: 1. 2. 3. Click the Clear All button. Click the Save button. 3.Click the Next button to go to the next page and Click the Previous button to return the previous page.

Note: If you set the virtual server of the service port as 80, you must set the web management port on Security > Remote Management page to be any value except 80 such as 8080. Or else there will be a conflict to disable the virtual server.

5.6.2 Port Triggering

Some applications require multiple connections, like Internet games, video conferencing, Internet calling and so on. These applications cannot work with a pure NAT router. Port Triggering is used for some of these applications that can work with an NAT router. You can set up Port Triggering on this page shown in Figure 5-16:
Figure 5-16 Port Triggering Once configured, operation is as follows: 1. A local host makes an outgoing connection using a destination port number defined in the Trigger Port field. 2. The router records this connection, opens the incoming port or ports associated with this entry in the Port Triggering table, and associates them with the local host. 3. When necessary the external host will be able to connect to the local host using one of the ports defined in the Incoming Ports field. Trigger Port - The port for outgoing traffic. An outgoing connection using this port will "Trigger" this rule Trigger Protocol - The protocol used for Trigger Ports, either TCP,UDP, or All (all protocols supported by the router) Incoming Ports Range - The port or port range used by the remote system when it responds to the outgoing request. A response using one of these ports will be forwarded to the PC that triggered this rule. You can input at most 5 groups of ports (or port section). Every group of ports must be apart with ",". For example, 2000-2038, 2050-2051, 2085, 3010-3030 Incoming Protocol - The protocol used for Incoming Ports Range, either TCP or UDP, or ALL (all protocols supported by the router) Enable - The Enable checkbox enables port forwarding for the application Common Applications - Some popular applications already listed in the pull-down list To add a new rule, enter the following data on the Port Triggering screen 1. Enter a port number used by the application when it generates an outgoing request. 2. 3. 4. 5. 6. Select the protocol used for Trigger Port from the pull-down list, either TCP, UDP, or All. Enter the range of port numbers used by the remote system when it responds to the PC's request. Select the protocol used for Incoming Ports Range from the pull-down list, either TCP, UDP, or All. Select the Enable checkbox to enable. Click the Save button to save the new rule.
There are many popular applications in the Popular Application list. You can select it and the ID, then click the Copy to button, the application will fill in the Trigger Port, incoming Ports Range boxes and select the Enable checkbox. It has the same effect as adding a new rule. Modifying an existing rule: 1. Edit the entry as desired. 2. Click the Save button.

Deleting an existing rule: 1. 2. Clear all the content in the Trigger Port field, the Open Port field and the Enable checkbox. Click the Save button.
To delete all rules: Click the Clear All button. Click the Save button
Note: When the trigger connection is released, the according opening ports will be closed Each rule allowed to be used only by one host on LAN synchronously. The trigger connection of other hosts on LAN will be refused Incoming Port Range cannot overlap each other

5.6.3 DMZ

The DMZ host feature allows one local host to be exposed to the Internet for a special-purpose service such as Internet gaming or videoconferencing. DMZ host forwards all the ports at the same time. Any PC whose port is being forwarded must have its DHCP client function disabled and should have a new static IP address assigned to it because its IP address may change when using the DHCP function. You can set up DMZ host on this page shown in Figure 5-17:
Figure 5-17 DMZ To assign a computer or server to be a DMZ server: 1. 2. 3. Click the Enable radio button Enter the local host IP address in the DMZ Host IP Address field Click the Save button.
Note: After you set the DMZ host, the firewall related to the host will not work.

5.6.4 UPnP

The Universal Plug and Play (UPnP) feature allows the devices, such as Internet computers, to access the local host resources or devices as needed. UPnP devices can be automatically discovered by the UPnP service application on the LAN. You can configure UPnP on this page shown in Figure 5-18:
Figure 5-18 UPnP Settings Enable UPnP - UPnP can be enabled or disabled by clicking the Enable or Disable button. As allowing this may present a risk to security, this feature is disabled by default Current UPnP Settings Table - this table displays the current UPnP information App Description - The description provided by the application in the UPnP request External Port - External port, which the router opened for the application Protocol - Which type of protocol is opened Internal Port - Internal port, which the router opened for local host IP Address - The UPnP device that is currently accessing the router Status - Either Enabled or Disabled, Enabled means that port is still active, otherwise, the port is inactive Click Refresh to update the Current UPnP Settings List.

TP Link Router Basic Setup

Introduction

The TP-Link #TL-R402M Cable/DSL Router is a broadband router. Detailed information is on the vendors web site at http://www.tp-link.com. A router assigns Dynamic Host Configuration Protocol (DHCP). This means the router assigns Internet Protocol (IP) addresses to all connected equipment configured to request on. The two basic rules for DHCP: Only one router can be active in the same group of connected equipment. Each equipment item must have a unique IP address. If two devices get the same IP, erratic behavior will result most often the duplicate IP will fail to communicate.
By default, DHCP is on in this router.

You must own or purchase 1 network cable; the most common is a 6 foot length. While sold under various names, make sure it is Cat5E type, with the RJ-45 connectors.

Installation Planning

Consult the TP-Link Quick Installation Guide for an overview. The TP-Link TL-R402M unit is a broadband router, so it must work with your cable or dsl modem. Your existing Cable or DSL modem must also have one Ethernet port, which is probably connected to your PC.
Double-check that your internet works with the existing Cable or DSL modem before you try to add the router. If you dont have functioning internet before proceeding, contact your Internet Service Provider (ISP). Rev. 1.3 01/07/2009
Home Installation of the TP-Link Router
1. Power down all existing equipment (computer, cable/dsl modem, etc.). 2. Locate a suitable location for the TP-Link router. 3. On your cable or dsl modem, find the Ethernet port and follow the (network) cable from the port of the modem to the network card on the PC. 4. Unplug the PC end of the cable, and plug it into the WAN port on the TP-Link router. [Note: you use the WAN port if you will leave DHCP on and use this device as a router.]

LAN ports

5. Now take the extra Ethernet cable (from page 1), and plug one end into the network port on the PC (where you just removed your modems cable in step 4 above). 6. Plug the other end of the extra cable into any open LAN port on the TP-Link router (see picture in step #4). Tip: It can keep you organized to use port #1, but this isnt strictly necessary. 7. Connect the A/C adapter to the router, and it will power on. 8. Power on the primary PC and the cable/dsl modem. 9. Recheck that your basic internet still works on the PC. 10. Proceed to the Weather Direct gateway installation, if that is your goal (www.weatherdirect.com).
Note: If you have internet service problems at this point, the two most common errors are: a) a mistake in the cabling, so check the connections in steps 1-9 again or b) missing that DHCP is enabled on either the cable/dsl modem or some other routing device. Only one device can serve DHCP, so competing devices need DHCP disabled. If you have any additional needs, you will need to consult the TP-Link Users Guide on the CD that came with the router or our Router Trouble-Shooting handout.
