This appendix is intended to help you troubleshoot problems you may encounter while setting up and using the
Netopia 4752. 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 4752. These
event histories can be accessed in the Statistics & Logs screen.
This section covers the following topics:
■ “Configuration Problems” on page A-1
■ “How to Reset the Netopia 4752 to Factory Defaults” on page A-3
■ “Power Outages” on page A-3
■ “Technical Support” on page A-4
Configuration Problems
If you encounter problems during your initial configuration process, review the following suggestions before
calling for technical support. There are five zones to consider when troubleshooting initial configuration:
1. The computer’s connection to the Netopia 4752
2. The Netopia 4752’s connection to the telecommunication line(s)
3. The telecommunication line’s connection to your ISP
4. The ISP’s connection to the Internet
5. The Netopia 4752’s connection to the voice provider
If the connection from the computer to the Netopia 4752 was not successful, verify that the following
conditions are in effect:
■ The Netopia 4752 is turned on.
■ An Ethernet cable connects your PC’s Ethernet card or built-in Ethernet port to the Netopia 4752.
■ 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 4752’s subnet
mask.
