5. Configuration

5.1. Accessing the Web Management Interface

To configure your router, you need to access its web-based management interface.

1. Connect your computer to the router via Wi-Fi (SSID and password are on the label at the bottom of the router) or an Ethernet cable.
2. Open a web browser (e.g., Chrome, Firefox, Edge).
3. Type the default IP address 192.168.10.1 into the address bar and press Enter.
4. Enter the default login credentials. The default username is admin and the default password is admin (or as printed on the router label).
5. Follow the on-screen instructions for the initial setup wizard, if prompted. It is recommended to change the default login password for security.

5.2. Basic Wi-Fi Settings

Navigate to the "Wireless" or "Wi-Fi Settings" section in the web interface to customize your wireless network.

• SSID (Network Name): Change the default Wi-Fi network name to a unique name.
• Password (Security Key): Set a strong, secure password for your Wi-Fi network. WPA2-PSK AES is recommended.
• Security Mode: Select WPA2-PSK.

5.3. LTE/Internet Settings

The router should automatically detect your SIM card and configure the LTE connection. If not, you may need to manually configure the APN (Access Point Name) settings provided by your mobile operator.

1. Go to the "Network" or "LTE Settings" section.
2. Check the connection status. If "Disconnected" or "Limited," verify APN settings.
3. Select "Manual" APN configuration if automatic fails and enter the correct APN, username, and password from your mobile operator.
4. Save changes and reboot the router if prompted.

5.4. VoLTE Configuration

The Cudy LT300 supports VoLTE functionality. If your SIM card and mobile operator support VoLTE, you may find settings under "Voice" or "VoLTE" in the web interface to enable or configure this feature. Consult your mobile operator for specific VoLTE settings if required.
