Introduction
Thank you for choosing the Instant Wireless™ Wireless Access Point Router. This Router will allow you to set up a network with your PCs and even share your Internet connection.
How does the Router do all of this? By connecting your ADSL modem directly to the Router and using the Router's Ethernet ports to connect your PCs, it's almost as if each PC is connected directly to the Internet. In this way, you can have several PCs utilizing one Internet connection simultaneously. Plus, because it's also an Access Point, the Router can bridge your Ethernet network with your wireless PCs.
But what does all of this mean?
Networks are useful tools for sharing computer resources. You can access one printer from different computers and access data located on another computer's hard drive. Networks are even used for playing multiplayer video games. So, networks are not only useful in homes and offices, they can also be fun.
The PCs you connect to the Router's four LAN ports, when properly configured, create a LAN, or Local Area Network. They are connected with an Ethernet cable plugged into your computer's Ethernet adapter at one end and into one of the Router's LAN ports (numbered from one to four) at the other end. The term "Ethernet" is used to refer to your network accessories, such as cables and adapters, because Ethernet refers to the type of network you are setting up. In your Router's documentation, Ethernet refers to accessories that transfer computer data from 10Mbps to 100Mbps. (10Mbps and 100Mbps refer to the speeds used by network devices. When transferring data at 10Mbps, you are moving the equivalent of over seven floppy disks every second! Network accessories that function at 100Mbps move data ten times faster!)
PCs can also interact with the Router wirelessly. By configuring your wireless PCs with the same wireless settings as the Router, you can bridge these wireless PCs while integrating them into your existing Ethernet network.
Perhaps the most remarkable thing the Router does is to allow you to share your ADSL connection. This is done by connecting your ADSL modem to the Router's WAN port with an Ethernet cable. (WAN refers to a Wide Area Network.) The Internet is a network that, being global, covers the widest area of all! The PCs connected to the Router share this connection.
Use the instructions in this Fast Start to help you connect the Router, configure your PCs, and configure the Router in your network. These instructions should be all you need to get you up and running with a basic network, sharing your Internet access. The Router also comes equipped with more advanced functions, but these functions should not be utilized without a further understanding of routers and networks.
This is What You Will Be Setting Up

The Router's setup is similar to that shown in the figure above for any Windows PC. The Router lets you share your ADSL connection among several computers in your home or business. This is called a Local Area Network or LAN.
This Fast Start guide gives you the “big picture” of what you need to set up a basic home or business network. The next three sections explain how you will set up and configure your equipment to enable shared high-speed access to the Internet.
Step 1: Connect the Router
This walks you through the process of connecting the Router to your ADSL modem. Then, it shows you how your PCs are connected to the Router.
This describes how your PCs are configured to communicate with the Router.
This step walks you through some basic Router settings, making it work with your ADSL modem and your ISP's settings.

Note: This Fast Start Guide will direct you how to set up the Router with Ethernet cables. While the Router can be set up through a wireless connection, details about setting up the Router wirelessly will not be addressed in this Fast Start Guide. Those who wish to set up the Router through their wireless connection should refer to the Linksys website at www.linksys.com.
Step 1: Connect the Router

In Step 1, you will connect the Router to your ADSL modem and to your home or business computers.
First, make sure that all devices you'll be working with are powered down, including your PCs, modem, and the Router.
A. If you haven't already done so, connect your ADSL modem to the phone jack. (Follow the instructions from your ADSL modem's installation guide.)
B. Using an Ethernet cable, connect the LAN or Ethernet port of the ADSL modem to the Router's WAN port.

Securing your wireless network
Using radio waves, a wireless network introduces some security risks which are not present in a wired network; an unauthorized third party can intercept transmitted data, gain access to your wireless network, ... In order to make your wireless network as secure as a wired network you should apply, at least, the following guidelines:
1. Change the SSID
Your wireless network is identified on the basis of an SSID (Service Set Identifier). This parameter, which can be considered as the networkname, is broadcasted periodically through a beacon. Also the SSID is, in most cases, set default to a welknown value. To improve the security you can :
- disable the SSID broadcast. Users who want to connect to your wireless network must know this value to become connected. Also, your wireless network becomes invisible to a third party.
- change the default value of the SSID. The SSID can contain maximal 32 characters and it's best to choose a value which is not too obvious.
2 Activate WEP
To guarantee that your data is transmitted in a private manner, you should activate WEP (Wired Equivalent Privacy). Use of this protocol will result in your data being encrypted while travelling through the air. Choose the largest encryption key possible (in most cases this is 128 bits) and make sure that each PC on your wireless network uses the same key as the access point. You can even improve the security by changing the WEP-key on a regular base.
3 Activate MAC-address control list
By means of the MAC-address list, also known as the Association Control List, you can determine which client adapters can access your wireless network. This is done by introducing the MAC-address of the client adapter in the concerned list of the access point. A MAC address consists of 12 characters (0-9,A-F) and can be found on the back of the client adapter. A client adapter whose MAC address is not included in the list will not be granted access to your wireless network.
4 Change / activate passwords
Configuration of the access point is done through a web browser. Secure this access, and any other access which may exist, by a carefully chosen password. If a default password, set by the manufacturer, is used, you should replace this by your own password.

- I'm having problems connecting to the Internet, what LEDs should be lit on the front of the Router?
- Each Router's LED will light up for any proper connection made on the back of the Router—whether it is an Ethernet cable or power cord.
For example, the following are typical LEDs that light up once a computer and DSL modem are connected:
- When the Router is turned on (the power adapter is plugged into the Router), the Power LED lights up.
- When an Ethernet cable is properly connected between a PC and Port 4 of the Router, the Link/Act, Ful/Col, and 100 LEDs in Column 4 light up.
- ADSL modem connection causes the WAN Link LED to light up.
• My WAN Link LED isn't lit. What should I check?
- Check that the cable you are using between your ADSL modem and the Router is the same cable that came with your modem. Depending on the type of connection your modem uses, you may need either a "straight-through" or "crossover" Ethernet cable (the "straight-through" type is more common).
- Some of the lights on the front of the Router don't light up when I plug in a PC.
- Only the Link/Act LED is required for a connection to work correctly.
- I cannot get onto the Internet, nor can I access the Router's Setup page. What should I check?
A. First check that the ADSL modem and computers are properly connected to the Router. See Question #2 for how to verify that the connections are good.
B. Then, check that you have properly configured your PCs to communicate with the Router. Below you will find instructions for the various versions of Windows.
- Windows 98 SE, or ME
- Click the Start menu, and then click Run. After the Run window appears, enter winipcfg in the Open field, and then click the OK button.
- When the IP Configuration window appears, click the gray box with a black arrow pointing down.
- A list of adapters will appear. Select the adapter that you use to connect to the Internet. These items should not contain "PPP", "VPN", "AOL", or "Dial-Up adapter" as part of the entry.
- The IP Address field should show an IP address of 192.168.1.100 or 192.168.1.xxx, with "xxx" being any number greater than 100. If your IP address is not in that range, hold the reset button on the front of the Router for more than 30 seconds. This will cause your Router to be set to factory default, so you will need to re-configure the Router's Setup page. After re-configuring the Setup page, restart the computer.
- Windows NT, 2000, and XP
- Click the Start menu, and then click Run. After the Run window appears, enter cmd in the Open field, and then click the OK button.
- This will open a command prompt. Enter ipconfig /all and then press the Enter key.
- The IP Address field should show an IP address of 192.168.1.100 or 192.168.1.xxx, with "xxx" being any number greater than 100. If your IP address is not in that range, hold the reset button on the front of the Router for more than 30 seconds. This will cause your Router to be set to factory default, so you will need to re-configure the Router's Setup page. After re-configuring the Setup page, restart the computer.
C. Now you will configure some settings in Windows.
- Go to your desktop and double-click My Computer, and then double-click Control Panel (Windows XP users using the default interface, click Start, and then select Control Panel).

- Click the Apply button to save the settings.
- Continue doing this until you find the channel that provides the best range.
Configuring Wireless Security

Note: WEP encryption is an additional data security measure and not essential for router operation.
An acronym for Wired Equivalent Privacy, WEP is an encryption method used to protect your wireless data communications. WEP uses a combination of 64-bit or 128-bit keys to provide access control to your network and encryption security for every data transmission. To decode a data transmission, each point in a network must use an identical 64-bit or 128-bit key. Higher encryption levels mean higher levels of security, but due to the complexity of the encryption, they may mean decreased network performance.
You may also have heard the term “40-bit” used in conjunction with WEP encryption. This is simply another term for 64-bit WEP encryption. This level of WEP encryption has been called 40-bit because it uses a 40-bit secret key along with a 24-bit Initialization Vector (40 + 24 = 64) . Wireless vendors may use either name. Linksys uses the term “64-bit” when referring to this level of encryption.
Make sure your wireless network is functioning before attempting to configure WEP encryption.
A 128-bit WEP encrypted wireless network will NOT communicate with a 64-bit WEP encrypted wireless network. Therefore, make sure that all of your wireless devices are using the same encryption level. All wireless devices complying with the 802.11b standard will support 64-bit WEP.
In addition to enabling WEP, Linksys also recommends the following security implementations:
- Changing the SSID from the default “linksys”
- Changing the WEP key regularly

Note: In order for WEP Encryption to be enabled, wireless functions must first be enabled. Select Enable on the Router's Wireless tab before proceeding.
The following steps will show you how to utilize WEP encryption
- From the Web-based Utility's Setup tab, select Mandatory under the WEP section.
- Press the WEP Key Setting button to set the WEP Encryption type and level.
- The screen displayed in Figure C-1 may appear, verifying that you are enabling WEP Encryption. Press the OK button to continue.
- This will display the screen shown in Figure C-2. From this screen, you will choose your WEP Encryption settings.

Figure C-1

Figure C-2
- WEP (64Bit or 128B) Select the level of encryption from the drop-down box. 128-bit WEP encryption is unique to Linksys and may conflict with other vendors' WEP encryption.

Note: In order to utilize WEP encryption, all points in your wireless network must have WEP enabled and be set to the same Key Setting.
The WEP Encryption key is generated in one of two ways:
- You may create an encryption key by using a Passphrase.
a. Enter a Passphrase, a user-defined password, into the Passphrase field. The Passphrase can be a maximum of 31 letters, symbols, and numbers. No spaces can be used.
b. Click the Generate button to create a key. The key will be 10 digits if you chose 64-bit encryption, or 26 digits if you chose 128-bit encryption. This key will be used to encrypt and decrypt the data being sent between the Router and your network's wireless PCs.
The Key field may not display all digits. Using the mouse, click anywhere within the Key field. Move the cursor to the right to view the rest of the Key. Make sure your write down the entire Key EXACTLY the way it is displayed.
- You may enter the encryption key manually.
Make a note of the Passphrase or Manual Key. You will need it for the other wireless devices on the network, as the same WEP encryption key must be entered in all wireless devices on the network.
Once you have chosen your key encryption method and entered either the Passphrase or manual key, click the Apply button, and the encryption portion of the setup is complete.

Note: In Windows XP, a 128-bit Key generated by the Router will be called a "104 bits (26 digits)" key, and a 64-bit Key generated by the Router will be called a "40 bits (10 digits)" key.
Configuring Wireless Security in Windows XP
As Windows XP does not allow for the use of the Linksys Passphrase feature with the wireless PC adapters, you will need to manually enter the key generated in the previous section.
The following steps will help you enable WEP and enter the encryption key manually for your wireless PC cards, in order to enable your Windows XP system to communicate with the Router wirelessly.
These steps assume that your CD-ROM drive is letter D and that you are running Windows XP in the default mode.
Be sure you have the WEP Key generated by the Router.
