24.2 ZyXEL Device Access and Login
V I forgot the IP address for the ZyXEL Device.
1 The default 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 1.6
on page 36.
V I forgot the password.
1 The default admin password is 1234, and the default user password is user.
2 If this does not work, you have to reset the device to its factory defaults. See Section 1.6
on page 36.
V 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 6.2 on page 90), 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
the Quick Start Guide.
3 Make sure your Internet browser does not block pop-up windows and has JavaScripts
and Java enabled. See Appendix B on page 341.
4 If you disabled Any IP (Section 6.6.7 on page 102), 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.)
• If there is a DHCP server on your network, make sure your computer is using a
dynamic IP address. See Appendix A on page 319. Your ZyXEL Device is a DHCP
server by default.
• If there is no DHCP server on your network, make sure your computer’s IP address is
in the same subnet as the ZyXEL Device. See Appendix A on page 319.
