|Most routers use something along the lines of 192.168.x.y|
Where x - is anything from 0 - 254 and y similarly.
Try using 192.168.0.1 or 192.168.1.1; or .22.214.171.124 or 192.168.1.254
Those are the most commonly used ip addresses for router management access.
Another way to discover what the ip address is to open the cm.exe (dos) box and type:
note the space between ipconfig and /all
This will show several ip addresses; one of which will be the default gateway that's address you're looking for.
This is a list of most of the default ip addresses for routers... from which it appears the zyxel default is: 192.168.1.1 - and login/password : admin / 1234
If you still can't get in... possibly reset the router to factory state; and try again with the address as above?
Remember to gain access to wifi settings - after a reset - you must use cat-5/ethernet connection. Likewise if changing the SSID without a reset - still use the cat-5/ethernet connection.
Incidentally this very olde article is interesting; and may be worth a read:
Seems after a firmware update the default ip address changed to 192.168.10.1; but the poster did get in using the 192.168.1.1 address?
The default gateway is the address you use - regardless.
To run the cmd.exe (or simply cmd) go:
Start/run and type "cmd" (no " ") and press enter. A small window will open into which you type:
and press enter.
When you change the SSID - remember to write it down on a sticker on the base of the router; and also make a hard copy somewhere safe; even email it to yourself too and store in a saved messages folder on line (a form of free cloud storage). Similarly any other changes you make...
