How to configure dynamic DNS on your modem
Dynamic DNS (DDNS) associates the WAN IP address of your router with a hostname, and automatically updates DNS servers upon WAN IP address change. DDNS is a separate service from a third-party provider.
NOTE: Depending on your model, your modem's user interface may appear slightly different from the images below.
1. Connect a device, such as a computer or tablet, to the internet through WiFi or using an Ethernet cable connected to your modem.
2. Open a web browser and type http://192.168.0.1 into the web address field.
3. Log in to the modem's settings interface (Modem GUI) using your Admin Username and Admin Password. Note that these are different from your wireless network name (SSID) and WiFi password (security 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 or lose your modem sticker, which includes your default admin username and password. These preset credentials cannot be retrieved, and your modem could become unusable without them.
The modem sticker shows you TWO important sets of login credentials. How do you use each one?
SSID and key/wireless password: Used to access and connect to your WiFi network
- SSID is the name that will show up on your devices in the list of wireless networks (may have two for dual-band modem/routers)
- Key/Wireless Password is the password you will enter on your devices to connect securely to your network
- These default settings can also be customized in the modem settings or through the app
Admin username and admin password: Used to log in to your modem settings portal
- Access secure settings such as firmware updates, WiFi security, schedules, and more
- When connected to your home network, go to http://192.168.0.1 to access the portal (also called the GUI)
- These default settings can also be customized in the modem settings
4. Select the Advanced Setup icon in the main menu.
5. Select "Dynamic DNS" in the left sidebar. This menu option may appear in the WAN Settings section or in the IP Addressing section, depending on your particular model.
6. Follow the steps to edit the Dynamic DNS settings.
- Step 1: Enable/Disable the dynamic DNS state.
- Step 2: Enter your DNS host username and password (must be set up separately at the third-party site).
- Step 3: Enter the dynamic DNS host name from the third-party provider.
- Step 4: Click "Apply" to save your changes.
