An Introduction to LANs and WANs

Simply put, a router is a network device that connects two networks together.

In this instance, the Router connects your Local Area Network (LAN), or the group of PCs in your home or office, to the Wide Area Network (WAN) that is the Internet. The Router processes and regulates the data that travels between these two networks.

Instant WirelessTM Series

Think of the Router as a network device with two sides. The first side is made up of your private Local Area Network (LAN) of PCs. The other, public side is the Internet, or the Wide Area Network (WAN), outside of your home or office.

The Router’s firewall (NAT) protects your network of PCs so users on the public, Internet side cannot “see” your PCs. This is how your LAN, or network, remains private. The Router protects your network by inspecting the first packet coming in from the WAN port before delivery to the final destination on the LAN port. The Router inspects Internet port services like the web server, ftp server, or other Internet applications, and, if allowed, it will forward the packet to the appropriate PC on the LAN side.

IP Addresses

What’s an IP Address?

IP stands for Internet Protocol. Every device on an IP-based network, including PCs, print servers, and routers, requires an IP address to identify its “location,” or address, on the network. This applies to both the WAN and LAN connections.

There are two ways of assigning an IP address to your network devices.

Static IP Addresses

A static IP address is a fixed IP address that you assign manually to a PC or other device on the network. Since a static IP address remains valid until you disable it, static IP addressing insures that the device assigned it will have that same IP address until you change it. Static IP addresses are commonly used with network devices such as server PCs or print servers.

If you use the Router to share your cable or DSL Internet connection, contact your ISP to find out if they have assigned a static IP address to your account. If so, you will need that static IP address when configuring the Router. You can get the information from your ISP.

Note: Since the Router is a device that connects two networks, it needs two IP addresses—one for the LAN side, and one for the WAN side. In this User Guide, you’ll see references to the “WAN IP address” and the “LAN IP address.”

Since the Router has firewall security (NAT), only the Router’s WAN IP address can be seen from the Internet.

However, even the WAN IP address can be blocked, so that the Router and network seem invisible to the Internet—This is shown in the Filters section in “Chapter 5: Using the Routers Web-Based Utility”.

Wireless Access Point Router with 4-Port Switch

Dynamic IP Addresses

A dynamic IP address is automatically assigned to a device on the network, such as PCs and print servers. These IP addresses are called “dynamic” because they are only temporarily assigned to the PC or device. After a certain time period, they expire and may change. If a PC logs on to the network (or the Internet) and its dynamic IP address has expired, the DHCP server will assign it a new dynamic IP address.

For DSL users, many ISPs may require you to log on with a user name and password to gain access to the Internet. This is called “Point to Point Protocol over Ethernet” or PPPoE. PPPoE is similar to a dial-up connection but does not have a phone number to dial into, and PPPoE is a dedicated high-speed connection. PPPoE also will provide the Router with a dynamic IP address to establish a connection to the Internet.

DHCP (Dynamic Host Configuration Protocol) Servers

DHCP frees you from having to assign IP addresses manually every time a new user is added to your network. PCs and other network devices using dynamic IP addressing are assigned a new IP address by a DHCP server. The PC or network device obtaining an IP address is called the DHCP client. The Router’s WAN port is, by default, set as a DHCP client.

DHCP servers can either be a designated PC on the network or another network device, such as the Router. By default, a DHCP server is enabled on your Router’s LAN ports. If you already have a DHCP server running on your network, you must disable one of the two DHCP servers. If you run more than one DHCP server on your network, you will experience network errors, such as conflicting IP addresses. To disable the Router’s DHCP function, see the DHCP section in Chapter 3: Configuring the Router.

Note: Even if you assign a static IP address to a PC, other PCs can still use DHCP’s dynamic IP addressing, as long as the static IP is not within the DHCP range of the LAN IP Address.

If the Router’s DHCP function fails to provide a dynamic IP address for any reason, please refer to Appendix A: Troubleshooting.

The Wireless Access Point Router’s Ports

T h e

Figure 1-2

Router’s rear panel (as shown in Figure 1-2) is where all of its connections are made.

WAN	The WAN (Wide Area Network) Port is where you will con-
	nect your cable or DSL modem with an Ethernet cable. Your
	modem connection will not work from any other port.
Ports 1-4	These four LAN (Local Area Network) ports are where you
	will connect networked devices, such as PCs, print servers,
	and any other Ethernet devices you want to put on your net-
	work. If Port 4 is being used, the Uplink Port will not work.
Uplink	The Uplink Port is where you can expand your network by
	connecting to another switch or hub. Uplinking to another
	switch or a hub is done by simply running a cable from the
	Uplink Port to the other device. The Uplink Port is shared
	with Port 4. If the Uplink port is being used, Port 4 will not
	work.
Power	The Power Port is where you will connect the included AC
	Power adapter.

Antenna Jacks The Antenna Jacks are where the included antennas are connected.

The Reset Button

Pressing the Reset Button and holding it in for a few seconds will clear all of the Router’s data and restore the factory defaults. This should be done only if you are experiencing heavy routing problems, and only after you have exhausted all of the other troubleshooting options. By resetting the Router, you run the risk of creating conflicts between your PCs’ actual IP Addresses and what the Router thinks their IP Addresses should be. You may be forced to reboot each network PC.

If the Router locks up, simply press the reset button or power it down for three to five seconds by removing the power cable from the Router’s Power Port. Leaving the power off for too long could result in the loss of network connections.

Chapter 2: Connecting the Router

Before You Start

Before plugging everything together, it’s always a good idea to have everything you’ll need to get the Router up and running. Depending upon how you configure the Router in Chapter 4: Configuring the Router, you may need some of the following values from your ISP:

When connecting through a Static IP connection, be sure to have 1) Your broadband-configured PC’s fixed Internet IP Address, 2) Your broadbandconfigured PC’s Computer Name and Workgroup Name, 3) Your Subnet Mask, 4) Your Default Gateway, and 5) Your Primary DNS IP address.

When connecting through a PPPoE connection, be sure to have 1) Your PPPoE User Name and 2) Your PPPoE Password.

The installation technician from your ISP should have left this information with you after installing your broadband connection. If not, you can call your ISP to request the data.

Once you have the above values, you can begin the Router’s installation and setup.

Connecting Your Hardware Together and Booting Up

Once you are sure that you have the above values on hand, you can begin the Installation and Setup of the Router.

1.Power everything down, including your PCs, your cable or DSL modem and the Router.

2.Connect an Ethernet cable from one of

your PC’s Ethernet ports to one of the Router’s LAN ports (as shown in Figure 2- 1). Do the same with all the PCs you wish to connect to the Router. (LAN Port 4 will become inactive if you use the Uplink port.)

In addition to accessing the Router through

Figure 2-1

Instant WirelessTM Series

an Ethernet connection, a wireless connection can be used to access the Router. See the “For Wireless Connections” section that follows these connection instructions.

3.Connect another Ethernet cable from your cable or DSL modem to the Router’s WAN port (as shown in Figure 2-2).

4. Connect the Power Adapter (included) to

the Router’s Power port (as shown in Figure	Figure 2-2
the Router’s Power port (as shown in Figure
2-3) and plug the other end into a power
outlet.
• The Power LED will illuminate green
as soon as the power adapter is con-
nected.
• The Diag LED will illuminate red for a
few seconds while the Router goes
through its internal diagnostic test. The
LED will turn off when the self-test is
complete.	Figure 2-3
	Figure 2-3

5.Power on the cable or DSL modem. Verify that the power is on by checking the Link LED in the WAN column on the front of the Router. The Link LED will be illuminated if the power is on and the modem is ready.

6.Press the Reset button on the back of the Router. Hold the button in for three seconds, or until the Diag LED illuminates red. This restores the Router’s default settings.

7.Power on your PC.

The Router is now connected. Continue to the next chapter to configure your PCs.

Wireless Access Point Router with 4-Port Switch

For Wireless Connections: In addition to accessing the Router through an Ethernet connection, a wireless connection can be used to access the Router. After powering on the Router and connecting it to your modem, enter the Router’s IP Address in the Address field of your wireless PC’s web-browser as follows: http://192.168.1.1 and press Enter.

Important: The Wireless Access Point Router with 4-Port Switch is configured by default to work out of the box with all Linksys Wireless Adapters. If you have changed the defaults on your Linksys Wireless Adapters, or are using other wireless adapters, you must temporarily change your wireless adapter settings to: (SSID = linksys) in order to initially access the Router wirelessly. After you have accessed the Router with the default settings, you can change the router settings to coincide with your Network settings and reset your adapters.

Important: Some ISPs—most notably some cable providers—config- ure their networks so that you do not have to enter a full Internet address into your web browser or e-mail application to reach your home page or receive your e-mail. If your Internet home page address is something very simple, such as “www”, rather than “www.linksys.com”, or your e-mail server’s address is something similar to “e-mail” or “pop3”, rather than “pop.mail.linksys.com”, you won’t be able to properly configure the Router until you determine the actual Internet addresses of your Web and e-mail connections.

You must obtain this information prior to connecting the Router to your network. You can obtain this information by contacting your ISP.

PPPoE

Some DSL-based ISPs use PPPoE ( Po i n t - t o - Po i n t Protocol over Ethernet) to establish communications with an enduser. If you are using a DSL line, check with your ISP to see if they use PPPoE. If they do use PPPoE, select this from the drop-down menu (as shown in Figure 5-5).

Figure 5-5

If you do enable PPPoE, remember to remove any existing PPPoE applications already on any of your PCs.

DHCP

A DHCP (Dynamic Host Configuration Protocol) Server a u t o m a t i c a l l y assigns IP addresses to each computer on its network. Unless you already have one, you should set the Router up as a DHCP server. This is done on the DHCP tab, shown in Figure 5-9.

Figure 5-9

•DHCP Server Click the Enable option to enable the Router’s DHCP server function If you already have a DHCP server on your network, set the Router’s DHCP option to Disable.

•Starting IP Address Enter a numerical value for the DHCP server to start with when issuing IP addresses.

•Number of DHCP users Enter the maximum number of PCs that will require IP addresses assigned by the Router. No more than 253 computers can be used. In order to determine the DHCP IP Address range, add the starting IP address (e.g., 100) to the number of DHCP users. By default, as shown in Figure 5-9, if you add 50 users, the range or IP Addresses will be 192.168.1.100 to 192.168.1.149.

•Client Lease Time The Client Lease Time is the amount of time a network user will be allowed connection to the Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased” this dynamic IP address.
