Chapter 4: Quick Installation Guide

After connecting the MR0-WR541G Router into your network, you should configure it. This chapter describes how to configure the basic functions of your MR0-WR541G Wireless Router. These procedures only take you a few minutes. You can access the Internet via the router immediately after successfully configuring.

4.1 TCP/IP configuration

The default IP address of the MR0-WR541G 54Mbps 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 PC to the LAN ports of the router. There are then two ways to configure the IP address for your PC.

¾Configure the IP address manually

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

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)

¾Obtain an IP address automatically

1)Set up the TCP/IP Protocol in "Obtain an IP address automatically" mode on your PC. If you need instructions as to how to do this, please refer to Appendix B: "Configuring the PC."

2)Power off the router and PC. Then turn on the router and restart the PC. The built-in DHCP server will assign IP address for the PC.

Now, you can run the Ping command in the command prompt to verify the network connection between your PC 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.

If the result displayed is similar to that shown in figure 4-1, the connection between your PC and the router has been established.

- 8 -

MR0-WR541G 54M Wireless Router User Guide

Figure 4-1 Successful 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.

Figure 4-2 Failed result of Ping command

Please check it following these steps:

1.Is the connection between your PC and the router correct?

Note: The 1/2/3/4 LEDs of LAN port which you link to 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 Network

Figure 5-2 the Network menu

There are three submenus under the Network menu (shown in figure 5-2): LAN, WAN and MAC Clone. Click any of them, and you will be able to configure the corresponding function. The detailed explanations for each submenu are provided below.

5.4.1 LAN

You can configure the IP parameters of LAN on this page.

Figure 5-3 LAN

¾MAC Address - The physical address of the router, as seen from the LAN. The value can't be changed.

¾IP Address - Enter the IP address of your router in dotted-decimal notation (factory default: 192.168.1.1).

¾Subnet 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 of the DHCP server 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/BigPond Cable/L2TP/PPTP) for Internet. The default type is Dynamic IP. 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

- 16 -

MR0-WR541G 54M Wireless Router User Guide

Static IP. If you are given a user name and a password, please select the type of your ISP provided(PPPoE/BigPond/L2TP/PPTP). 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):

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 your ISP.

Note: If you get address and find error 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

- 17 -

MR0-WR541G 54M Wireless Router User Guide

this option. (This is rarely required.)

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
