23.2  ZyXEL Device Access and Login
I forgot the IP address for the ZyXEL Device.
1
The default IP address is 192.168.1.1.

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.

If this does not work, you have to reset the device to its factory defaults. See

I forgot the password.
