2. On your wireless client device (e.g., laptop, smartphone), press its WPS button or activate WPS through its settings. This should be done within 2 minutes of pressing the WPS button on the ZyXEL device.

Manual Wireless Connection (No WPS)

If WPS is not available or preferred, you can connect manually using the SSID and wireless key.

1. Locate the device's wireless network name (SSID) and password (wireless key). These are often printed on a sticker on the bottom of the device.
2. On your wireless client device, search for available Wi-Fi networks.
3. Select the device's SSID (e.g., "CenturyLink0001" or "CenturyLink0001_5G").
4. Enter the wireless key (passphrase) when prompted to connect.

Advanced Setup: GPON Interface

The device allows for advanced configuration of GPON WAN interfaces. You can add or remove interfaces as needed. It is recommended to create interfaces in a specific order, for example, creating 'veip0' first, then 'veip1'.

Wall Mounting

The ZyXEL C424G can be mounted on a wall for convenient placement.

1. Attach the mounting bracket to the wall using appropriate screws and anchors. Ensure it is level and secure.
2. Align the device with the mounting bracket.
