How to change WiFi settings on the Zyxel C3510XZ modem

The WiFi network settings for the Zyxel C3510XZ gateway must be accessed through the Zyxel modem settings interface. This article will show you how to log in on a computer or other connected device and view or change your WiFi password and/or your network name (SSID). This allows you to set a custom name and password to make your network more secure and easier to recognize and access.

How to change WiFi settings through the user interface

1.  On a computer or tablet that is connected to your network, open a web browser and type http://192.168.0.1 into the web address field.

Entering the URL for the modem settings interface

2.  Log in to the Zyxel settings using your Admin Username and Password. These are printed on the sticker found on the side of your modem. Note that these are different from your wireless network name (SSID) and password (key).

You can find the Admin Username and Password printed on the sticker attached to the side, back or bottom of the modem.

CAUTION! Do not remove your modem sticker. It includes your default admin username and password, which cannot be retrieved if lost. Your modem could become unusable without them. 

3.  On the home screen, locate the WiFi Settings block. Here you will see a summary of your WiFi network information, including whether the 2.4 GHz and 5 GHz frequency bands are enabled or disabled, plus the network name (SSID) and password for each band. To edit these settings, click on the arrow in the lower corner of the box.
