Common Problems and Solutions

Wireless-G Broadband Router

Appendix A: Troubleshooting

This appendix consists of two parts: “Common Problems and Solutions” and “Frequently Asked Questions.”
Provided are possible solutions to problems that may occur during the installation and operation of the Router.
Read the descriptions below to help you solve your problems. If you can’t find an answer here, check the Linksys
website at www.linksys.com.

Common Problems and Solutions

1. I’m trying to access the Router’s Web-based Utility, but I do not see the login screen. Instead, I see a

screen saying, “404 Forbidden.”

If you are using Windows Explorer, perform the following steps until you see the Web-based Utility’s login
screen (Netscape Navigator will require similar steps):

1. Click

File

. Make sure

Work Offline

is NOT checked.

2. Press

CTRL + F5

. This is a hard refresh, which will force Windows Explorer to load new webpages,

not cached ones.

3. Click

Tools

. Click

Internet Options

. Click the

Security

tab. Click the

Default level

button. Make sure

the security level is Medium or lower. Then click the

OK

button.

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

You can assign a static IP address to a PC by performing the following steps:
•

For Windows 98SE and Me:

1. Click

Start

,

Settings

, and

Control Panel

. Double-click

Network

.

2. 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.

3. 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 computer on the network connected to the Router.
Make sure that each IP address is unique for each PC or network device.

4. 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.

5. 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.

6. Click the

OK

button in the TCP/IP properties window, and click

Close

or the

OK

button for the Network

window.

7. Restart the computer when asked.
