Plug & Play 4G Connectivity

The MB115-4G is designed for immediate use. Simply insert a nano SIM card compatible with FDD-LTE and TDD-LTE networks, and the router automatically creates a Wi-Fi hotspot.

With support for up to 32 simultaneous connections, it handles multiple laptops, tablets, and smartphones without performance drops. The inclusion of WPS push-button setup simplifies connecting new devices securely.

Enhanced Coverage with External Antennas

Four external antennas provide stable, efficient signal distribution throughout your space. This design helps overcome obstacles and extend coverage to areas where internal antennas might struggle. Whether you’re in a rural location or a building with thick walls, the MB115-4G converts strong 4G signals into reliable whole-home Wi-Fi.

Wired Networking Options

Beyond wireless connectivity, the router features four Fast Ethernet (10/100 Mbps) LAN ports for connecting wired devices like desktop PCs, smart TVs, or network storage.
