25.2 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 30 .

default.

in the same subnet as the ZyXEL Device. See Appendix A on page 175 .
