In "HiLink" mode, the device presents itself to the host as a USB Ethernet adapter (using the CDC-ECM or RNDIS protocol). The modem operates as a self-contained router: Users often want to switch between HiLink and Stick modes
Let’s break it down.
The Huawei E3372 is one of the most ubiquitous 4G/LTE USB modems released to date. Known alternatively in various markets as the E3372h or E3372s, the device gained a reputation not only for its reliability as a consumer connectivity tool but also as a highly sought-after piece of hardware for networking enthusiasts, embedded systems developers, and IoT integrators. Its popularity stems from its robust Hilink architecture, high compatibility with mobile networks globally, and the ability to modify the firmware to suit advanced networking applications (such as use with OpenWrt routers). The E3372’s compact design and driver-less setup (on
is a "stick" modem that draws power directly from a USB port, making it a favorite for long-term deployments where downtime is not an option. Technical Specifications and Performance Huawei E3372
The is a widely recognized 4G LTE USB dongle valued for its reliability, speed, and versatility in both consumer and industrial applications. Unlike many modern mobile hotspots that rely on internal batteries, the
: It supports dual-stack routing (IPv4/IPv6), which is critical for maintaining compatibility with modern European and global network operators.
There are two primary hardware revisions of this device, which are critical to distinguish for technical users:
