How to use

Insert a compatible SIM card for 4G LTE access or connect a WAN line via the RJ‑45 port if required. Power the router and connect devices either via the Gigabit Ethernet LAN ports or wirelessly on the 2.4 GHz band. Access the router’s web management interface using the default IP address to configure network name (SSID), Wi‑Fi password, and security settings.

Recommendations

Place the router in a central, elevated location free from large obstacles to improve 2.4 GHz coverage. For improved security, change default administrator credentials and use a strong WPA2-PSK password. If higher wireless throughput or dual-band operation is required, consider a router that supports 5 GHz and newer Wi‑Fi standards.
