Appendix A: Troubleshooting

Wireless-G Broadband Router with 2 Phone Ports

This appendix provides solutions to problems that may occur during the installation and operation of the Router. Read the description below to solve your problems. If you can't find an answer here, check the Internet phone service provider website or the Linksys website at www.linksys.com.

Common Problems and Solutions

1.I don’t hear a dial tone, and the PHONE1 (or PHONE2) LED is not lit. Go through this checklist until your problem is solved:

•Make sure the telephone is plugged into the appropriate port, Phone 1 or Phone 2.

•Disconnect and re-connect the RJ-11 telephone cable between the Router and telephone.

•Make sure your telephone is set to its tone setting (not pulse).

•Make sure your network has an active Internet connection. Try to access the Internet, and check to see if the Router’s Internet LED is lit. If you do not have a connection, power off your network devices, including the Router and cable/DSL modem. Wait 30 seconds, and power on the cable/DSL modem first. Then power on the Router and other network devices.

•Verify your account information and confirm that the phone line is registered with your Internet phone service provider.

2.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): A. Click File. Make sure Work Offline is NOT checked.
