Chapter 23 Troubleshooting

23.2 ZyXEL Device Access and Login

I forgot the IP address for the ZyXEL Device.

1The default IP address is 192.168.1.1.

2If 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.

3If this does not work, you have to reset the ZyXEL Device to its factory defaults. See Section 23.1 on page 281.

I forgot the password.

1The default admin password is 1234, and the default user password is user.

2If this does not work, you have to reset the ZyXEL Device to its factory defaults. See Section 23.1 on page 281.

I cannot see or access the Login screen in the web configurator.

1Make sure you are using the correct IP address.

The default IP address is 192.168.1.1.

If you changed the IP address (Section 23.1 on page 281), 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.

2Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick Start Guide and Section 23.1 on page 281.

3Make sure your Internet browser does not block pop-up windows and has JavaScripts and Java enabled. See Section 23.1 on page 281.

4If you disabled Any IP (Section 23.1 on page 281), make sure your computer is in the same subnet as the ZyXEL Device. (If you know that there are routers between your computer and the ZyXEL Device, skip this step.)

5Reset the ZyXEL Device to its factory defaults, and try to access the ZyXEL Device with the default IP address. See Section 23.1 on page 281.

6If the problem continues, contact the network administrator or vendor, or try one of the advanced suggestions.
