After inserting the SIM card, connect the router to a stable power source using the provided adapter. Most 4G LTE CPE routers feature status indicator lights that display network connection progress. A solid signal light typically indicates successful registration with the cellular network. For initial configuration, connect a computer to the router either via Ethernet cable or through the default Wi-Fi network (usually identified on a label attached to the router). Access the administration interface by entering the default IP address (commonly 192.168.1.1 or 192.168.0.1) into a web browser. The setup wizard will guide you through basic configuration, including administrator password creation and time zone settings.

Wi-Fi Network Customization and Security

Establishing secure wireless connectivity represents a crucial step in configuring your 4G LTE router with SIM card slot. Within the administration interface, navigate to the wireless settings section to customize your network name (SSID) and password. For optimal security, select WPA2 or WPA3 encryption rather than older, vulnerable protocols like WEP. If your router supports dual-band operation, configure both 2.4GHz and 5GHz networks—the former offers better range while the latter provides faster speeds with less interference. Consider enabling features like hidden SSID for additional security if you're in a high-density living environment common in Hong Kong's apartment buildings. Finally, apply your settings and reconnect all your devices using the new credentials.
