Appendix C: Installing the

TCP/IP Protocol

Follow these instructions to install the TCP/IP protocol on one of your PCs

only

after a network card has been successfully installed inside the PC. These

instructions are for Windows 95, Windows 98, and Windows Me. For TCP/IP

setup under Windows NT, 2000, and XP, see your Windows manual.

1. Click the

Start

button. Choose

Settings

and then

Control Panel

2. Double-click on the

Network

icon to bring up your Network window.

Select the

Configuration

tab.

3. Click the

fields.

In the "Network key" field, enter the exact Key (all 10 or 26 digits, depend-

ing on the level of encryption) generated by the Gateway.

Verify that the “Key format” field displays “Hexadecimal digits” and that

the “Key length” field displays either “40 bits (10 digits)” or “104 bits (26

digits)”. If this is not displayed, you have entered the key incorrectly.

Click the

button to save the settings.

Click on

buttons until you

get back to the “Wireless Network Connection Status” window.

Close any

open windows to get back to the Windows XP desktop.

Close any applications and reboot your PC.

After reboot, WEP configuration

is complete and you should be able to connect wirelessly to the Gateway.

6. Find and double-click

TCP/IP

in the list to the right (see Figure C-2).

After a few seconds, the main Network window will appear.

The TCP/IP

Protocol should now be listed.

8. Click the

button. Windows may ask for original Windows installation

files. Supply them as needed, e.g., c:\windows\options\cabs, D:\win98,

D:\win95.

Windows will ask you to restart the PC. Click the

Yes

button.

The TCP/IP installation is now complete.

Appendix D: Finding the MAC

Address and IP Address for Your

Ethernet Adapter

This section describes how to find the MAC address for your Ethernet adapter

to do either MAC Filtering for the Gateway and ISP.

You can also find the IP

address of your computer’s Ethernet adapter.

The IP address is used for filter-

ing.

Follow the steps in this appendix to find the MAC address or IP address

for your adapter in Windows 95, 98, Me, NT, 2000, and XP.

For Windows 95, 98, and Me:

1. Click on

Start

and

Run

. In the Open field, enter

winipcfg

. Then press the

Enter

key or the

button.

2. When the IP Configuration window appears, select the Ethernet adapter

you are using to connect to the Gateway via a CAT 5 Ethernet cable.

In the command prompt, enter

ipconfig /all

. Then press the

Enter

key.

Write down the Physical Address as shown on your computer screen; it is

the MAC address for your Ethernet adapter.

This will appear as a series of

letters and numbers.

The MAC address/Physical Address is what you will use for MAC

Filtering.

The example in Figure D-5 shows the IP address of your Ethernet adapter

as 192.168.1.100. Your computer may show something different.

Figure D-5

Note

: The MAC address is also called the Physical

Address.

Write down the Adapter Address as shown on your computer screen (see

Figure D-3).

This is the MAC address for your Ethernet adapter and will

be shown as a series of numbers and letters.

The MAC address/Adapter Address is what you will use for MAC

Filtering.

The example in Figure D-3 shows the IP address of your Ethernet adapter

as 192.168.1.100. Your computer may show something different.

For Windows NT, 2000, and XP:

The following steps show an alternative way of obtaining the MAC address and

IP address for your Ethernet adapter.

1. Click on

Start

and

Run

. In the Open field, enter

cmd

. Press the

Enter

key

or click the

button.

Note

: The MAC address is also called the Adapter

Address.

Appendix E: Glossary

10BaseT

- An Ethernet standard that uses twisted wire pairs.

100BaseTX

- IEEE physical layer specification for 100 Mbps over two pairs of

Category 5 UTP or STP wire.

802.11b

- One of the IEEE standards for wireless networking hardware.

Products that adhere to a specific IEEE standard will work with each other,

even if they are manufactured by different companies. The 802.11b standard

specifies a maximum data transfer rate of 11Mbps, an operating frequency of

2.4GHz, and WEP encryption for security. 802.11b networks are also referred

to as Wi-Fi networks.

Adapter

- Printed circuit board that plugs into a PC to add to capabilities or

connectivity to a PC. In a networked environment, a network interface card

(NIC) is the typical adapter that allows the PC or server to connect to the

intranet and/or Internet.

Auto-negotiate

- To automatically determine the correct settings. The term is

often used with communications and networking. For example, Ethernet

10/100 cards, hubs and switches can determine the highest speed of the node

they are connected to and adjust their transmission rate accordingly.

Beacon Interval

A beacon is a packet broadcast by the Access Point to keep

the network synchronized. A beacon includes the wireless LAN service area,

the AP address, the Broadcast destination addresses, a time stamp, Delivery

Traffic Indicator Maps, and the Traffic Indicator Message (TIM).

Bit

- A binary digit. The value - 0 or 1-used in the binary numbering system.

Also, the smallest form of data.

Boot

- To cause the computer to start executing instructions. Personal comput-

ers contain built-in instructions in a ROM chip that are automatically executed

on startup. These instructions search for the operating system, load it and pass

control to it.

When entering the information using the Router’s web-based utility, you will

type the

12-digit MAC address

in this format, XXXXXXXXXXXX

without

the hyphens

for MAC Filtering.
