Assigning static Internet information to your PCs

If you are a typical user, you will not need to assign static Internet information to your

LAN PCs because your ISP automatically assigns this information for you.

In some cases however, you may want to assign Internet information to some or all of

your PCs directly (often called “statically”), rather than allowing the device

to assign it.

This option may be desirable (but not required) if:

You have obtained one or more public IP addresses that you want to always

associate with specific computers (for example, if you are using a computer as

a public web server).

You maintain different subnets on your LAN (subnets are described in

Appendix B).

Before you begin, you must have the following information available:

The IP address and subnet mask of each PC

The IP address of the default gateway for your LAN. In most cases, this is the

address assigned to the LAN port on the device. By default, the LAN port is

assigned the IP address 192.168.1.1. (You can change this number or another

number can be assigned by your ISP.)

The IP address of your ISP’s Domain Name System (DNS) server.

On each PC to which you want to assign static information, follow the instructions

relating only to checking for and/or installing the IP protocol. Once it is installed,

continue to follow the instructions for displaying each of the Internet Protocol (TCP/IP)

properties. Instead of enabling dynamic assignment of the IP addresses for the

computer, DNS server and default gateway, click the radio buttons that enable you to

enter the information manually.

Note

Your PCs must have IP addresses that place them in the same

subnet as the

device

’s LAN port.

Configuring Wireless PCs

You need to configure the operating system installed on your Wireless PCs using the

same procedure described for Configuring Ethernet PCs section.

Positioning the wireless PCs

The wireless network cards used determine the maximum distance between your

wireless PCs and your device. Guidelines on positioning the hardware components of

your wireless network should be provided by your network card provider.

Wireless PC cards and drivers

Each PC on your wireless LAN must be fitted with a wireless access card. You must

also install the corresponding driver files for your particular wireless card on your PC.

You should receive driver files and instructions on how to install them together with

your wireless card.

Configuring PC access to your Wireless device

Before you start configuring your Wireless PC, you must ensure that you have:

A Wireless access card for each of the PCs

Corresponding wireless access card driver software files

The configuration steps below will vary depending on both the operating system and

wireless card installed on the PC. These steps provide a basic outline, however you

should refer to the documentation provided with your wireless access card for specific

instructions.

To configure Wireless PCs:

Install the wireless access card.

Install the wireless driver software files.

Configure the following wireless parameters on each of the wireless PCs:

•

Set the adapter to use infrastructure mode. This configures the PCs to access each

other and the Internet via the device.

Configure the SSID and channel to match the SSID and channel previously

configured on the device.

Your wireless network can now communicate with the Internet via the device.

LEDs

Power LED does not illuminate

after product is turned on.

Verify that you are using the power cable

provided with the device and that it is securely

connected to the

device and a wall

socket/power strip.

LINK LAN LED does not

illuminate after Ethernet cable is

attached.

Verify that the Ethernet cable is securely

connected to your LAN hub or PC and to the

device. Make sure the PC and/or hub is turned

on.

Verify that your cable is sufficient for your

network requirements. A 100 Mbit/sec network

(10BaseTx) should use cables labeled CAT 5.

A 10Mbit/sec network may tolerate lower

quality cables.

Internet Access

My PC cannot access the Internet

Run a health check on your device. Use the

ping utility (discussed in the following section)

to check whether your PC can communicate

with the device’s LAN IP address (by default

192.168.2.1). If it cannot, check the Ethernet

cabling.

If you statically assigned a private IP address

to the computer, (not a registered public

address), verify the following:



Check that the gateway IP address on the

computer is your public IP address (see

Current Status on page 1 for instructions

on viewing the IP information.) If it is not,

correct the address or configure the PC to

receive IP information automatically.



Verify with your ISP that the DNS server

specified for the PC is valid. Correct the

address or configure the PC to receive

this information automatically.

My LAN PCs cannot display

web pages on the Internet.

Verify that the DNS server IP address specified

on the PCs is correct for your ISP, as

discussed in the item above. If you specified

that the DNS server be assigned dynamically

from a server, then verify with your ISP that the

address configured on the device is correct,

and then you can use the ping utility, discussed

on page 73, to test connectivity with your ISP’s

DNS server.

Use the ping utility, discussed in the following

section, to check whether the PC can

communicate with the device’s LAN IP address

(by default 192.168.2.1). If it cannot, check the

Ethernet cabling.

Verify that you are using Internet Explorer or

Netscape Navigator v4.0 or later.

Verify that the PC’s IP address is defined as

being on the same subnet as the IP address

assigned to the LAN port on the device

.

Diagnosing Problem using IP Utilities

Ping

Ping is a command you can use to check whether your PC can recognize other

computers on your network and the Internet. A ping command sends a message to

the computer you specify. If the computer receives the message, it sends messages

in reply. To use it, you must know the IP address of the computer with which you are

trying to communicate.

On Windows-based computers, you can execute a ping command from the Start

menu. Click the Start button, and then click Run. In the Open text box, type a

statement such as the following:

ping 192.168.1.1

Click OK. You can substitute any private IP address on your LAN or a public IP

address for an Internet site, if known.

If the target computer receives the message, a Command Prompt window is

displayed:

If the target computer cannot be located, you will receive the message Request timed

out.

Using the ping command, you can test whether the path to the device is working

(using the preconfigured default LAN IP address 192.168.1.1) or another address you

assigned.

You can also test whether access to the Internet is working by typing an external

address, such as that for www.yahoo.com (216.115.108.243). If you do not know the

IP address of a particular Internet location, you can use the nslookup command, as

explained in the following section.

From most other IP-enabled operating systems, you can execute the same command

at a command prompt or through a system administration utility.

Nslookup

You can use the nslookup command to determine the IP address associated with an

Internet site name. You specify the common name, and the nslookup command looks

up the name in on your DNS server (usually located with your ISP). If that name is not

an entry in your ISP’s DNS table, the request is then referred to another higher-level

server, and so on, until the entry is found. The server then returns the associated IP

address.

On Windows-based computers, you can execute the nslookup command from the

Start menu. Click the Start button, and then click Run. In the Open text box, type the

following:

Nslookup

Click OK. A Command Prompt window displays with a bracket prompt (>). At the

prompt, type the name of the Internet address that you are interested in, such as

www.microsoft.com

.

The window will display the associate IP address, if known, as shown below:

There may be several addresses associated with an Internet name. This is common

for web sites that receive heavy traffic; they use multiple, redundant servers to carry

the same information.

To exit from the nslookup utility, type

exit

and press

[Enter]

at the command prompt.
