Configuration problems
If you encounter problems during your initial configuration process, review the following suggestions before
calling for technical suppor t. 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, and
4. the ISP’s connection to the Internet.
If the connection from the computer to the router was not successful, check the following:
■
The Netopia R2121 is turned on.
■
An Ethernet cable connects your PC’s Ethernet card or built-in Ethernet por t to the Netopia R2121.
■
The Smar tStar t application is running and able to access the Netopia R2121.
■
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:\windowselnet.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 R2121’s subnet
mask.
■
If you are entering a new IP address via Smar tStar t be sure the correct serial number was entered.
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 R2121 to the factor y default before
reinitiating the configuration process. For fur ther information on resetting your Netopia R2121 to factor y
default, see
“Factor y defaults” on page 15-7 .
