Appendix A: Troubleshooting

This appendix consists of two parts: “Common Problems and Solutions” and

“Frequently Asked Questions.” Provided are possible solutions to problems

regarding the installation and operation of the Router. If your situation is described

here, the problem should be solved by applying the corresponding solution. If you

can’t find an answer here, check the Linksys website at

1. I need to set a static IP address on a PC.

The Router, by default, assigns an IP address range of 192.168.1.100 to

192.168.1.150 using the DHCP server on the Router. To set a static IP address, you

can only use the ranges 192.168.1.2 to 192.168.1.99 and 192.168.1.151 to

192.168.1.254. Each PC or network device that uses TCP/IP must have a unique

address to identify itself in a network. If the IP address is not unique to a network,

Windows will generate an IP conflict error message.

You can assign a static IP

address to a PC by performing the following steps:

For Windows 95, 98, and Me:

A. Click

Start

,

Settings

, and

Control Panel

. Double-click

Network

.

B. In

The following network components are installed

box, select the

TCP/IP->

associated with your Ethernet adapter. If you only have one Ethernet adapter

installed, you will only see one TCP/IP line with no association to an Ethernet

adapter.

Highlight it and click the

Properties

button.

C.

In the

TCP/IP properties

window, select the

IP address

tab, and select

Specify

an IP address

. Enter a unique

IP address

that is not used by any other com-

puter on the network connected to the Router. You can only use an IPaddress

in the ranges 192.168.1.2 to 192.168.1.99 and 192.168.1.151 to

192.168.1.254.

Make sure that each IP address is unique for each PC or net-

work device.

D.

Click the

Gateway

tab, and in the

New Gateway

prompt, enter

192.168.1.1

,

which is the default IP address of the Router. Click the

Add

button to accept

the entry.

E.

Click the

DNS

tab, and make sure the

DNS Enabled

option is selected. Enter

the

Host

and

Domain

names (e.g., John for Host and home for Domain).

Enter the

DNS entry

provided by your ISP. If your ISP has not provided the

DNS IP address, contact your ISP to get that information or go to its website

for the information.

F.

Click the

OK

button in the

TCP/IP properties

window, and click

Close

or

the

OK

button for the Network window.

G.

Restart the computer when asked.

Common Problems and Solutions

The Router’s

MAC address

is a 12-digit code assigned to a unique piece of

hardware for identification, like a social security number. If your ISP requires

MAC address registration, find your adapter’s MAC address by following the

instructions in “Appendix F: Finding the MAC Address and IP Address for

Your Ethernet Adapter.”

Enter the 12 digits of your adapter’s MAC address in the on-screen fields (see

Figure 9-23). This “clones” your network adapter’s MAC address onto the

Router, so you do NOT have to call your ISP to change the registered MAC

address to the Router’s MAC address.

When finished making your changes on this tab, click the

Apply

button to save

these changes, or click the

Cancel

button to undo your changes.

Note:

This is a

sample

screen.

Please enter the

MAC

Address

for your Network

Card/Adapter

into this field.
