Troubleshooting A-1

This appendix is intended to help you troubleshoot problems you may encounter while setting up and using the

Netopia 4541/4542. It also includes information on how to contact Netopia Technical Support.

Important information on these problems can be found in the event histories kept by the Netopia 4541/4542.

These event histories can be accessed in the Statistics & Logs screen.

This section covers the following topics:

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 4541/4542 is turned on.

■ An Ethernet cable connects your PC’s Ethernet card or built-in Ethernet port to the Netopia 4541/4542.

■ 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 4541/4542’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 4541/4542 to the factory default before

reinitiating the conﬁguration process. For further information on resetting your Netopia 4541/4542 to factory

default, see “How to reset the router to factory defaults” on page A-3.
