Wireless-G Router User's Manual

Introduction

Congratulations on purchasing a sophisticated, high-quality networking product. Your Wireless-G router is many devices in one, and was designed and manufactured to the highest standards. Still, like any digital electronic product, it requires proper setup and care. Follow the instructions in this manual carefully to ensure that your Wireless-G router will give you many years of trouble-free service.

Overview of the Router

Not long ago, to get all the functionality provided by your Wireless-G router, you would have had to buy three separate devices: a router (which at the time would have been just a router), a wireless access point (AP), and an Ethernet switching hub (now called an Ethernet switch or simply a switch).

(Why is it called a switch? Because it can switch each transmission to the port the destination machine is connected to. Early Ethernet hubs sent all transmissions out on all ports.)

You would have connected the router, the AP, and your computers together through the switch to form your local-area network (LAN). Then you would have connected the router to your modem for access to the wide-area network (WAN), that is, your ISP's network, and through it, the Internet.

With your Wireless-G router, everything is in one box, and the AP and router are connected internally to the switch. You only have to connect your computers to the

LAN ports and your modem to the WAN port.

For the most part in this manual, we will refer to the combination of router, AP, and switch as a unit. Terms like "the router" and "your router" should be understood to include the built-in AP and switch.

The Parts of the Router: The router has seven light-emitting diode (LED) indicators

on its front panel. These are described briefly below.

• ETHERNET indicators: Each of these corresponds to a LAN port on the back of the router. When a good but idle link is detected on the port, the indicator shines steadily; when there is activity on the link, the indicator blinks off and on.

• WIRELESS indicator: This indicator shines steadily when wireless networking is enabled but the router is not actively transmitting or receiving; blinks off and on

Wireless-G Router User's Manual

when there is wireless activity; and stays off when wireless networking is disabled.

• WAN indicator: This indicator shines steadily when a good but idle link is detected on the WAN port, and blinks off and on when there is activity on the WAN link.

• POWER indicator: This indicator flashes on and off during the router's power-on self-test, and shines steadily when the router is ready for operation.

The router has a button, five Ethernet ports, and a power receptacle on its back panel. These are described briefly below.

• Reset button: Press this button briefly to restart the router. The router will go through its power-on self-test and then resume operation. Press Reset for at least five seconds to restore the router's factory settings.

NOTE: Restoring the factory settings may cause your Internet and/or

wireless links to go down.

• WAN port: This is for the Ethernet connection to your DSL or cable modem.

• LAN ports: These are for Ethernet connections to computers and other devices on the LAN. These connections can be indirect: you can connect a hub or switch to a

LAN port, and then connect machines to the remaining Ethernet ports of the hub

or switch.

• DC12V receptacle: This is for connecting the AC power adapter included with the router.

WARNING: Use only the AC power adapter that came with the

router. Connecting any other power adapter may damage the router and cause a fire hazard.

Major Non-routing Functions: Besides performing the functions of a pure router,

AP, and switch, your Wireless-G router provides many other capabilities, some of which are provided on some networks by special-purpose devices or powerful servers. A few of the important ones are listed below.

• Login: Your ISP (especially if you use ADSL, VDSL, etc.) may have given you software for connecting to and disconnecting from the Internet. Such software is often called a login client. After the router is set up, you will no longer use any login client — the router will automatically log on for you.

Wireless-G Router User's Manual

(The router can connect automatically whenever you access the Internet, or it can stay connected all the time. The choice is yours.)

• DHCP: This stands for Dynamic Host Configuration Protocol. To communicate on the Internet, a machine needs Internet Protocol (IP) settings such as an IP address. The router is set at the factory to be a DHCP server, that is, to give machines on the LAN IP settings if they request them. Most computers are set by default to be DHCP clients, that is, to request IP settings from a DHCP server.

• NAT: This stands for Network Address Translation. The router uses one IP address on the LAN and another on the WAN. When a machine on the LAN sends a request to the Internet, the router changes the source IP address to its own WAN IP address. Any reply, therefore, is addressed to the router. The router changes the reply's destination IP address to that of the local machine originating the exchange, and places it on the LAN so that machine can receive it.

• Firewall: NAT helps protect your computers by hiding their IP addresses from the WAN. The router also has a firewall that performs "stateful packet inspection," monitoring each connection for abnormal activity. By default, the router blocks common denial-of-service (DoS) attacks. In fact, it blocks all attempts to connect from the Internet, but you can set it to accept connection types that you need.

The above list is far from complete. The router's other functions will be explained in the chapters on setup.

Care of the Router: Observe the following precautions to ensure that the router has a

long service life:

• Never block the air vents on the bottom and sides of the router.

• Use only the 12-volt, 0.5-ampere AC power adapter that came with the router.

• Keep the router away from liquids and moisture. Clean it only with a slightly damp cloth.

• Never open the router. For reasons of electrical safety, the router may only be opened by an authorized service technician.

About this Manual

A large part of this manual explains the router's setup utility — the user interface that the router displays to let you change router settings. In this section we explain the terminology we use to describe the setup utility. This will also help you understand the setup utility's organization and manner of operation.

The setup utility is coded, and served to your computer, in exactly the same way as a World Wide Web site, and you will view it with your Web browser, so some of our terminology comes from the language of the World Wide Web.

Wireless-G Router User's Manual

Many Web sites have links at the top of each page for displaying other pages on the site. Similarly, at the top of the setup utility are seven buttons that we call page buttons. Each takes you to a different page of the setup utility.

Most pages are made up of several panels. Panels contain the controls for setting the router. To change panels, you click panel tabs on the left.

Shown above is the Setup page's Basic Setup panel. It has two sections, named

Internet Setup and Network Setup, and the Internet Setup section has two

subsections, named Internet Connection Type and Optional Settings (required by

some ISPs). The first control in the Optional Settings (required by some ISPs)

subsection is the Router Name control, and its default (factory) setting is myrouter. This is the terminology we will use in this manual.

Important Concepts

If you are new to networking, you may encounter many unfamiliar terms when setting up the router. Those that appear most frequently and are most basic for understanding router settings are explained below.

IP Address: We have already touched on IP addresses without explaining them. A

thorough explanation would require a separate chapter, and is quite beyond the scope of this manual. A short explanation of IP addressing as it applies to your router, however, is necessary.

"IP" stands for "Internet Protocol," and IP addresses are the means by which networks and individual machines are identified on the Internet (and now on most LANs as well). An IP address is usually written in "dotted quad" notation — four numbers separated by "dots" (periods). Your Wireless-G router's default LAN-side IP address, for example, is 192.168.1.1. (It has no default WAN-side IP address; its "WAN IP" must be set manually or sent to the router by your ISP.)

Wireless-G Router User's Manual

Each number in an IP address takes up an octet — eight bits — of computer storage space, so its range is 0–255. Certain numbers, however, have special significance in certain positions. No machine's IP address can end in 0 or 255, for example.

Subnet Mask: Each machine on an IP network must have an IP address that is unique

on that network. All the machines, however, must share a set of values called a subnet mask. The router's default LAN-side subnet mask is 255.255.255.0. Combined with

the router's default LAN-side IP address of 192.168.1.1, this tells us (and all machines getting their IP settings from the router) —

• The first three numbers of the IP address — 192.168.1 — are the network portion of the address, shared by all machines on the LAN, and the fourth number is the host portion, unique to each machine.

• The machines on the LAN (including the router) can have.IP addresses from

192.168.1.1 to 192.168.1.254. Machines with addresses in this range are local, and can be reached directly.

• Machines with IP addresses outside this range can only be reached through a gateway such as the router.

DNS: We prefer names to IP addresses. The name www.bigcompany.com is likely to

identify a Web server in the domain of servers run by bigcompany, which is part of the domain of commercial enterprises on the Internet. To reach this server, we need its IP address. Our Internet software gets the address by contacting a Domain Name System (DNS) server, also called a name server. If one DNS server doesn't have a particular IP address in its tables, it can get it from a DNS server that does.

The IP address of at least one DNS server is a required setting for any machine that will access the Internet. On most types of Internet connections, the router can get at least one DNS server's IP address from your ISP, and it passes the address(es) to machines on the LAN that get their IP settings from the router.

MAC Address: Ethernet was developed separately from the Internet and has a very

different system of addressing. In Ethernet, each device is identified by its medium (or media) access control (MAC) address. This is a value that is assigned at the factory

and usually cannot be changed. The Institute of Electrical and Electronics Engineers (IEEE) administers a system that ensures that no two Ethernet devices in the world have the same MAC address.

A device's MAC address is usually printed on a sticker placed on the back or bottom of the device. Various formats are used, but the address is always in hexadecimal (base 16) notation and always consists of twelve hexadecimal digits. Two common formats are 12:34:56:78:9A:BC and 123456:789ABC .

Wireless-G Router User's Manual

Chapter 1: Required Setup

The router always requires some setup. There are several reasons:

• It works with six different kinds of Internet connection. Even if the default setting is the kind of connection you have, some setup may be required to get it working.

• Wireless networking is enabled by default. If you don't change some settings, your network will be open to possibly malevolent intruders.

• The router's setup utility is password-protected, but the default password is easy to find out. Unless you change the router password, anyone with access to your network can change router settings (and cut you off from your own network!).

Information You Need

Internet Connection Type: You will need information from your ISP, starting with

the type of Internet connection you have. That will be one of the following:

• Automatic Configuration – DHCP (the Dynamic Host Configuration Protocol)

• Static IP (fixed IP settings)

• PPPoE (the Point-to-point Protocol over Ethernet)

• PPTP (the Point-to-point Tunneling Protocol)

• L2TP (the Layer 2 Tunneling Protocol)

• Telstra Cable (BigPond broadband cable service)

Depending on which of these you use, other information may be required. It must be obtained from your ISP.

Wireless Environment: It is important to know in advance what kinds of wireless

stations will access the router: Wireless-G (802.11g), Wireless-B (802.11b), or both. If you are adding the router to an existing wireless network, you will need to know how that network is set up. You should also find out if other wireless equipment is operating nearby, so you can pick a channel that minimizes interference.

Preparation for Setup

Making Connections: It is assumed here that you have a computer connected to your

modem through an Ethernet cable, and that the computer has a Javascript-enabled Web browser installed. It is best to use this computer to set up the router.

(If your Internet connection type is Static IP or PPTP, this computer might have fixed IP settings. The computer that you use to set up the router must be set to obtain IP settings automatically. For information on checking and changing the setting, look up "automatic addressing" or "DHCP" with the operating system's Help function.)

Wireless-G Router User's Manual

Make connections for setup as follows:

1. Power down the modem.

Some modems are designed to stop working if they detect a change in the MAC address of the device connected to them.

2. Disconnect the Ethernet cable from the modem.

3. Plug the Ethernet cable into any one of the router's four LAN ports.

The Ethernet cable that led from the computer to the modem should now lead from the computer to the router.

4. Plug in and connect the router's AC power adapter.

The router will be ready for setup shortly after its POWER indicator stops flashing and starts shining steadily.

If you need to restore the router's factory defaults, press its Reset button for at least five seconds and wait until it is again ready.

You can connect the router's WAN port to the modem with an Ethernet cable and turn the modem on now, if you wish. From the point of view of security, however, it is better to do this after setup is complete.

Accessing the Setup Utility: If all has gone well, the computer will now have IP

settings (received from the router) that let you conveniently browse to the router's setup utility. Access the setup utility as follows:

1. Start up the Web browser.

If it tries to go to a start page on the Internet, click its Stop button or press Esc.

2. Type http://192.168.1.1/ into the browser's address bar and then press Enter.

You will be prompted for a user name and password.

3. Leave the User Name box blank, type admin into the Password box, and press

Enter (or click OK).

The Basic Setup panel of the setup utility's Setup page will appear.

Later, after the router and your LAN are fully set up and in operation, you will still be able to access the router's setup utility in this way: start up a browser on any computer networked to the router, type http:// plus the router's IP address into the address bar, press Enter, and supply the correct password when prompted (that password will be something other than admin if you follow our recommendations during initial setup).

Wireless-G Router User's Manual

Setup Utility Basics: Note the following characteristics of the setup utility:

• Each settings panel has a Save Settings button. After changing settings, you must click Save Settings to have the changes applied on the router.

• Switching panels cancels unsaved changes. Finish up in one panel before going to another.

• Many controls appear only when certain settings are selected. If you don't see a certain control at first, you will see it when you select a setting that makes it necessary.

• Although you log on to the setup utility by supplying a password, there is no procedure for logging off. After you save all your settings, you can simply close your browser or browse to other pages.

Setup for Internet Access

Internet Connection Type: To begin setup for Internet access, open the Internet Connection Type list and select your connection type.

• For almost all connection types, User Name and Password boxes will appear. If they do, be sure to click in these boxes and type in the strings required by your ISP.

NOTE: Your ISP may refer to the user name as a user ID, account

name, or "login."

• For almost all connection types, you can select either Connect on Demand or

Keep Alive. Click the option you want and set the time period you want; this is

not decided by your ISP.

Connect on Demand means automatically connecting to your ISP when Internet

access is needed, and then disconnecting when there has been no activity for a given number of minutes (the Max Idle Time setting).

Keep Alive means never breaking the connection, and automatically trying to

restore it if it goes down for a given number of seconds (the Redial Period setting).

Find your connection type below and follow the additional instructions given. When finished, go to "Optional Settings (required by some ISPs)," below.

• Automatic Configuration – DHCP: This is the most common connection type

for cable ISPs. The router will receive its WAN-side IP settings from a DHCP server on your ISP's network. Your ISP may require that you connect from a registered MAC address; in that case you must either (a) register the router's WAN-side MAC address with your ISP (this address is shown in the Status

Wireless-G Router User's Manual

page's Router panel), or (b) use the MAC Address Clone panel to change the router's WAN-port MAC address.

• Static IP: Use this setting if you have purchased a fixed IP address from your ISP and you are not using PPTP. All IP settings must be input manually: Internet IP

Address, Subnet Mask, Gateway, and at least one Static DNS server address.

All values must be obtained from your ISP.

• PPPoE: This is the most common connection type for DSL ISPs. You must input the User Name and Password settings required by your ISP. WAN-side IP settings will be received over the wire from your ISP when the router connects.

• PPTP: This is used by a minority of ISPs. You must input the User Name and

Password settings required by your ISP. If you have received fixed IP settings

from your ISP, you must input them in the Internet IP Address, Subnet Mask, and Gateway boxes. If these settings are assigned dynamically (over the wire), leave the Internet IP address set to 0.0.0.0.

• L2TP: This is used by a minority of ISPs. You must input the User Name,

Password, and L2TP Server IP address settings required by your ISP. WAN-

side IP settings will be received over the wire when the router connects.

• Telstra Cable: This is used on Telstra BigPond broadband cable connections in Australia. You must input the User Name and Password settings required by BigPond. Input the name of a heartbeat server if Telstra BigPond indicates that this is necessary on your connection; otherwise leave the Heart Beat Server box blank.

Optional Settings (required by some ISPs): Some of the settings in this group are

required on some Internet accounts. Your ISP can tell you which ones you need to set, if any.

• Router Name: This is not required by any ISP. It is for your reference, and does not affect operation. You can set this to any string you like, as long as it does not contain spaces and is no more than 39 characters long.

• Host Name and Domain Name: One or (more often) both of these may be required. Enter the strings your ISP has instructed you to use. Usually, a host name has no dots (www is a common host name), while a domain name has at least one dot (bigcompany.com, for example).

• MTU and Size: Information is sent over a network in chunks called packets. Packet size is measured in octets (also called bytes) of eight bits (1s and 0s) each. MTU stands for Maximum Transmission Unit. MTU size is the greatest allowable packet size on a given connection.

With the MTU control set to Auto, the router adjusts MTU size according to connection type (1500 for Ethernet, 1492 for PPPoE, 1436 for PPTP, and so on).

Wireless-G Router User's Manual

In very rare cases, an ISP may require an unusual MTU size. Where this is the case, set MTU to Manual and enter the value in the Size box.

This completes adjustment of settings in the Basic Setup panel's Internet Setup section. Some controls in the Network Setup section, however, are related to the Internet. Below are a few things you can do before you click Save Settings.

• If (1) you will use the router as a DHCP server for machines on the LAN, and (2) your ISP has given you the IP addresses of any DNS servers, you can enter those addresses in the Static DNS 1, 2, and 3 boxes. (For a connection type of Static IP, however, these addresses are entered not here but in the Internet Setup section.)

WINS stands for Windows Internet Name Service. If the router will be a DHCP server and you have been given the IP address of a WINS server, you can enter that address in the WINS boxes.

• You can select your time zone from the Time Zone list, and if Daylight Saving Time is not used in your area, you can uncheck Automatically adjust clock for

daylight saving changes.

The router will set its clock by obtaining Universal Coordinated Time readings from servers on the Internet and adding or subtracting the number of hours required for your time zone. This makes it possible for you to specify

when

particular machines can and cannot access the Internet.

Unless you are very knowledgeable about networking, we recommend not changing any other settings in the Network Setup section at this time.

Finishing Up: Click Save Settings to save and apply your settings on the router.

After a short wait, a success message and a Continue button will appear. Click

Continue to return to the Basic Setup panel.

Testing the Connection: If you wish to test the connection, we recommend making

the test brief for security reasons. Setup for Internet access may be complete, but required setup is not.

You will need a second Ethernet cable. Test the connection as follows:

1. Power up the modem.

2. Connect the router's WAN port to the modem with an Ethernet cable.

3. Point the browser directly at an Internet Web site.

Simply choose a site from your bookmarks or favorites. Do not run any program your ISP gave you for connecting and disconnecting. The router will do that for you from now on.

Wireless-G Router User's Manual

4. Return to the setup utility and turn the modem off.

If your settings are correct and you still cannot connect, the most likely cause is that your ISP requires the machine connected to the modem to have a particular MAC address. One solution is to register the MAC address of the router's WAN port with your ISP. You can find this MAC address by clicking the Status button.

Another solution is to use the MAC Address Clone function.

MAC Address Clone: If you can find out the MAC address that your ISP requires, or

it is the MAC address of the computer you are using to set up the router, you can "clone" the address to the router's WAN port. Do this as follows:

1. On the setup utility's Setup page, click the MAC Address Clone tab.

2. Click Enable.

3. Do one of the following:

If the address is not that of the computer being used to set up the router, enter the address in the User Defined Entry boxes.

If the address is that of the computer being used to set up the router, click Clone

Your PC's MAC.

4. Click Save Settings.

Setup for Wireless Networking

The router acts as a wireless access point (AP, also called a base station). Wireless clients (computers with wireless interfaces, also called wireless stations) connect to

the wired network, the Internet, and each other through the AP portion of the router.

• If you will not use wireless networking, click the Wireless page button, open the

Wireless Network Mode list, click Disabled, and click Save Settings. Then go

to "Setup for Router Security," below.

If you have a wireless client, we suggest starting up the client's wireless connection software and clicking Site Survey while the router is on.

The router will be detected (its default SSID, or wireless network name, is mySSID), and you will be able to join the network (this is usually done by double-clicking the displayed SSID). Anyone else in the vicinity with a wireless client can do this also. Setup is required to make the wireless network secure against intrusion.

While the Site Survey results are displayed, take note of the wireless channels used by any other APs or wireless networks operating in the vicinity.
