Troubleshooting the Web Configuration Interface
If you are unable to access the firewall’s Web Configuration interface from a PC on your local
network, check the following:
•
Check the Ethernet connection between the PC and the firewall as described in the previous
section.
•
Check the PC’s wireless settings and radio settings (if accessing the firewall using the wireless
features). Also check the Network Authentication scheme.
•
Make sure your PC’s IP address is on the same subnet as the firewall. If you are using the
recommended addressing scheme, your PC’s address should be in the range of 192.168.1.2 to
192.168.1.254.
•
If your firewall’s IP address has been changed and you don’t know the current IP address,
clear the firewall’s configuration to factory defaults. This will set the firewall’s IP address to
192.168.1.1. 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 firewall 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.
Note:
If your PC’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
PC to the firewall and reboot your PC.
