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.
