Chapter 4: Quick Installation Guide

After connecting the TL-WR642G Router into your network, you should configure it. This chapter describes how to configure the basic functions of your TL-WR642G Wireless Router. These procedures only take you a few minutes. You can access the Internet via the router immediately after successfully configured.

4.1 TCP/IP configuration

The default IP address of the TL-WR642G 108Mbps Wireless Router is 192.168.1.1, and the default Subnet Mask is 255.255.255.0. These values can be seen from the LAN. They can be changed as you 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

1)Set up the TCP/IP Protocol for your PC(s). If you need instructions as to how to do this, please refer to Appendix B: "Configuring the PCs."

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). If you need instructions as to how to do this, please refer to Appendix B: "Configuring the PCs."

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).

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 OS.

Open a command prompt, and type ping 192.168.1.1, then press Enter.

Figure 4-1: Successful result of Ping command

- 8 -

TL-WR642G 108M Wireless Router User Guide

If the result displayed is similar to that 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 that shown in figure 4-2, it means that your PC has not connected to the router. Please check it following these steps:

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

4.2 Quick Installation Guide

With a Web-based (Internet Explorer or Netscape® Navigator) utility, the TL-WR541G 54Mbps Wireless Router is easy to configure and manage. The Web-based utility can be used on any Windows, Macintosh or UNIX OS with a web browser.

Connect to the router by typing http://192.168.1.1 in the address field of web browser.

Figure 4-3 Login to the router

After a moment, a login window will appear similar to that shown in Figure 4-4. Enter admin for the User Name and Password, both in lower case letters. Then click the OK button or press the Enter key.

Mode - Indicates the current mode (108Mbps (Dynamic), 108Mbps (Static), 54Mbps (802.11g), 11Mbps (802.11b)). If you select 108Mbps (Dynamic), it is compatible with 54Mbps (802.11g) and 11Mbps (802.11b). If you select 54Mbps (802.11g), it is compatible with 11Mbps (802.11b).

These settings are only for basic wireless parameters, for advanced settings, please refer to Section 5.5: "Wireless."

Note: The change of wireless settings won't take effect until the router reboots! You can reboot it manually. If you need instructions as to how to do this, please refer to Section 5.11.4: "Rebooting the Router"

Click the Next button, you will then see the Finish page:

TL-WR642G 108M Wireless Router User Guide

5.4.1 LAN

You can configure the IP parameters of 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:

a.If you change the IP Address of LAN, you must use the new IP Address to login the router.

b.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.

c.If the new LAN IP Address you set is not in the same subnet, the Virtual Server and DMZ Host will change accordingly at the same time.

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/802.1x + Dynamic IP/802.1x + Static IP) to the Internet. The default type is PPPoE. If you aren’t 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 you are not sure which connection type you use currently, please contact your ISP to obtain 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):

- 15 -

TL-WR642G 108M Wireless Router User Guide

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.

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.

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).

If you are also given a user name and a password for 802.1x authentication, you should select 802.1x + Dynamic IP for WAN Connection Type, and a user name and a password will then appear, shown in figure 5-4a:

- 16 -

TL-WR642G 108M Wireless Router User Guide
