• Typical use: Mobile broadband access and local wireless networking

How to use

Install a compatible SIM card according to the device instructions, power on the router, and follow the on‑screen or web‑based setup procedure to establish the 4G LTE connection and configure wireless SSIDs and passwords. Choose whether to operate primarily on the 2.4 GHz band for wider coverage or the 5 GHz band for higher performance, or enable both simultaneously to let client devices select the best connection. Use the router’s management interface to adjust security settings, parental controls, or guest network options as required.

Usage recommendations

Place the router in a central, elevated location to improve Wi‑Fi coverage; position the device where it receives the best 4G signal (near a window or higher floor) for reliable mobile WAN performance. Regularly update the router firmware through the manufacturer’s interface to maintain security and compatibility. For optimal performance, connect high‑bandwidth devices to the 5 GHz band and legacy or long‑range devices to the 2.4 GHz band.
