3.4. Initial Configuration (Web Management Page)
- Connect your computer or mobile device to the router's Wi-Fi network. The default Wi-Fi SSID and password can be found on a label on the router, typically on the bottom or rear.

Figure 3.3: Example of Wi-Fi password label. Default Wi-Fi Key: Wa39ca97ae. Default Device IP: 192.168.1.1. Default User: admin. Default Password: A3a116e3.
- Open a web browser and enter the default IP address (e.g., 192.168.1.1) into the address bar.
- Log in using the default username and password (usually "admin" for both, or as specified on the label).
- The router should automatically detect your SIM card and attempt to connect to the 4G network. If it doesn't connect, you may need to manually configure the APN (Access Point Name) settings. Refer to your SIM card provider for the correct APN details.
- It is highly recommended to change the default Wi-Fi SSID and password, and the router's login password, for security purposes.
