CORRECTIVE ACTION
Make sure that you have the correct power adaptor connected to the Prestige and an
appropriate power source. Make sure that the power source is turned on. Check all cable
connections.
If the LEDs still do not turn on, you may have a hardware problem. In this case, you
should contact your local vendor.
Check the cable connection from your computer to the Prestige.
Make sure your computer's IP address is in the same subnet as the Prestige's IP address
(see Section 3.1 on page
Make sure your computer's Ethernet adapter is installed and functioning properly.
If the Prestige's IP address has changed, then enter the new one as the URL.
Use Internet Explorer 6.0 and later or Netscape Navigator 7.0 and later with JavaScript
enabled.
Make sure you enter the password correctly (the field is case sensitive).
If you've changed the Prestige's password and forgotten it, use the RESET button. Press
the button in for about 10 seconds (or until the PWR/SYS LED starts to blink), then
release it. It returns the Prestige to the factory defaults (password is 1234, LAN IP
address 192.168.1.1 etc.).
Verify the Internet connection settings in the wizard. Make sure you entered the correct
user name and password if you are using PPPoE or PPPoA.
Check the telephone connections.
You can test the telephone wire by using it to connect a telephone to a regular telephone
outlet and checking for a dial tone.
