This appendix is intended to help you troubleshoot problems you may encounter while setting up and using the Netopia 4553. It also includes information on how to contact Netopia Technical Support.

Configuration problems
If you encounter problems during your initial configuration process, review the following suggestions before calling for technical support. There are four zones to consider when troubleshooting initial configuration:
1.The computer’s connection to the router
2.The router’s connection to the telecommunication line(s)
3.The telecommunication line’s connection to your ISP
4.The ISP’s connection to the Internet
If the connection from the computer to the router was not successful, verify that the following conditions are in effect:
■The Netopia 4553 is turned on.
■An Ethernet cable connects your PC’s Ethernet card or
■Telnet is available on your PC or Macintosh. (On a PC, it must be specified in your system path. You can usually find the application as “c:\windows\telnet.exe”.)
■Your PC or Macintosh is properly configured for TCP/IP.
■Your PC or Macintosh has an IP address.
■Your PC or Macintosh has a subnet mask that matches or is compatible with the Netopia 4553’s subnet mask.
Note: If you are attempting to modify the IP address or subnet mask from a previous, successful configuration attempt, you will need to clear the IP address or reset your Netopia 4553 to the factory default before reinitiating the configuration process. For further information on resetting your Netopia 4553 to factory default, see “How to reset the router to factory defaults” on page
