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
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 Router is turned on.
■ An Ethernet cable connects your PC’s Ethernet card or built-in Ethernet por t to the Router.
■ 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 Router’s subnet mask.
