21.2 ZyXEL Device Access and Login
V I forgot the LAN IP address for the ZyXEL Device.
1 The default LAN IP address is 192.168.1.1.
2 Use the console port to log in to the ZyXEL Device.
3 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.
4 If this does not work, you have to reset the device to its factory defaults. See Section 2.3
on page 45.
V I forgot the password.
1 The default password is 1234.
2 If this does not work, you have to reset the device to its factory defaults. See Section 2.3
on page 45.

1 Make sure you are using the correct IP address.
• The default LAN IP address is 192.168.1.1.
• Use the ZyXEL Device’s LAN IP address when configuring from the LAN.
• Use the ZyXEL Device’s WAN IP address when configuring from the WAN.
• If you changed the LAN IP address (Section 5.7 on page 104), use the new IP address.
• If you changed the LAN IP address and have forgotten it, see the troubleshooting
suggestions for I forgot the LAN IP address for the ZyXEL Device.
2 Check the hardware connections, and make sure the LEDs are behaving as expected. See
the Quick Start Guide and Section 1.5.1 on page 39.
3 Make sure your Internet browser does not block pop-up windows and has JavaScripts
and Java enabled. See Appendix A on page 353.
4 Make sure your computer's Ethernet adapter is installed and functioning properly.
5 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.)
