2. Connect to the Router: Now, you need to connect to the router's Wi-Fi network. Look for the default Wi-Fi network name (SSID) and password, usually printed on a label on the router itself. Use your phone, laptop, or any other Wi-Fi-enabled device to connect.
3. Access the Web Interface: Open a web browser on your connected device and enter the router's default IP address in the address bar (e.g., 192.168.1.1 or 192.168.0.1). Again, this information is usually on the router's label. You'll be prompted to enter a username and password (default credentials are often 'admin' for both). If you've changed the password, use your new credentials.
4. Configure the Internet Settings: Once logged in, navigate to the internet or WAN settings. You might need to select the connection type as '4G/3G' or 'LTE'. The router should automatically detect your SIM card and connect to the mobile network. However, you might need to enter the Access Point Name (APN) provided by your mobile carrier. You can usually find this information on your carrier's website or by contacting their customer support. This is a very important step and the router won't work without it.
5. Set Up Wi-Fi Settings: Customize your Wi-Fi settings. Change the Wi-Fi network name (SSID) and password to something secure and easy for you to remember. You can also configure the Wi-Fi security type (WPA2 or WPA3 is recommended for the best security). This will secure your network.
6. Save and Reboot: After making changes, save your settings and reboot the router. It might take a minute or two for the router to restart and reconnect to the internet. Always reboot your router.
7. Test the Connection: Once the router has rebooted, test the internet connection by browsing the web or opening an app that requires an internet connection. If everything is working, you're all set! If not, proceed to the troubleshooting section.
