45.3 Device Access Problems
I do not know the IP address of the Zyxel Device.
1 The default IP address is 192.168.1.1
2 If you changed the IP address, you might be able to find the IP address of the Zyxel Device by looking
up the IP address of your computer’s default gateway. To do this in Microsoft Windows, click Start > Run,
enter cmd, and then enter ipconfig. The IP address of the Default Gateway might be the IP address of
the Zyxel Device, depending on your network environment.
3 If this does not work, reset the Zyxel Device to its factory defaults.
I forgot the admin password.
1 See the Zyxel Device label or this document’s cover page for the default admin password.
2 If you changed the password from default and cannot remember the new one, you have to reset the
Zyxel Device to its factory default settings.
I cannot access the Web Configurator login screen.
1 Make sure you are using the correct IP address.
• The default IP address is 192.168.1.1.
• If you changed the IP address (Section 10.2 on page 361), use the new IP address.
• If you changed the IP address and have forgotten the new address, see the troubleshooting
suggestions for I do not know the IP address of the Zyxel Device.
2 Check the hardware connections, and make sure the LEDs are behaving as expected.
3 Make sure your Internet browser does not block pop-up windows and has JavaScript and Java
enabled.
4 If it is possible to log in from another interface, check the service control settings for HTTP and HTTPS
(Maintenance > Remote Management).
