Troubleshooting the Web Configuration Interface
If you are unable to access the router’s web Configuration interface from a computer on your local
network, check the following:
• Check the Ethernet connection between the computer and the router as described in the
previous section.
• Make sure your computer’s IP address is on the same subnet as the router. If you are using the
recommended addressing scheme, your computer’s address should be in the range of
192.168.0.2 to 192.168.0.254. Refer to “Verifying TCP/IP Properties” on page C-8 or
“Verifying TCP/IP Properties for Macintosh Computers” on page C-19 to find your
computer’s IP address. Follow the instructions in Appendix C to configure your computer.
Note: If your computer’s IP address is shown as 169.254.x.x: Recent versions of Windows
and MacOS will generate and assign an IP address if the computer cannot reach a DHCP
server. These auto-generated addresses are in the range of 169.254.x.x. If your IP address is in
this range, check the connection from the computer to the router and reboot your computer.
• If your router’s IP address has been changed and you don’t know the current IP address, clear
the router’s configuration to factory defaults. This will set the router’s IP address to
192.168.0.1. This procedure is explained in “Restoring the Default Configuration and
Password” on page 8-7.
• Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet
Explorer, click Refresh to be sure the Java applet is loaded.
• Try quitting the browser and launching it again.
• Make sure you are using the correct login information. The factory default login name is
admin and the password is password. Make sure that CAPS LOCK is off when entering this
information.
If the router does not save changes you have made in the web Configuration Interface, check the
following:
• When entering configuration settings, be sure to click the APPLY button before moving to
another menu or tab, or your changes are lost.
• Click the Refresh or Reload button in the web browser. The changes may have occurred, but
the web browser may be caching the old configuration.
