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 Netopia D-Series
2. The Netopia D-Series’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 Netopia D-Series was not successful, verify that the following
conditions are in effect:
The Netopia D-Series is turned on.
An Ethernet cable connects your PC’s Ethernet card or built-in Ethernet port to the Netopia D-Series.
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 D-Series’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 D-Series to the factory default before
reinitiating the configuration process. For further information on resetting your Netopia D-Series to factory
default, see “Factory defaults” on page 9-96.
