Appendix A: Troubleshooting
Common Problems and Solutions

Wireless-N 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.
