43.2 Zyxel Device Access and Login
I forgot the IP address for the Zyxel Device.
1 The default LAN IP address is 192.168.1.1.
2 If you changed the IP address and have forgotten it, you might get the IP address of the Zyxel Device by
looking up the IP address of the default gateway for your computer. To do this in most Windows
computers, 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 (it depends on the network), so enter this IP address in your
Internet browser.
3 If this does not work, you have to reset the device to its factory defaults. See Section 1.4.5 on page 53.
I forgot the password.
1 See the cover page for the default login names and associated passwords.
2 If those do not work, you have to reset the device to its factory defaults. See Section 1.4.5 on page 53.
I cannot see or access the Login screen in the web configurator.
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 8.2 on page 177), use the new IP address.
• If you changed the IP address and have forgotten it, see the troubleshooting suggestions for I
forgot the IP address for the Zyxel Device.
2 Check the hardware connections, and make sure the LEDs are behaving as expected. See Section
Figure 19 on page 30.
3 Make sure your Internet browser does not block pop-up windows and has JavaScripts 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 MGMT).
5 Reset the device to its factory defaults, and try to access the Zyxel Device with the default IP address.
See Section 1.4.5 on page 53.
