The E8372 builds upon the E3372's foundation by adding integrated Wi-Fi capability—functioning as both a USB dongle and a mobile Wi-Fi hotspot. This versatility makes it an excellent choice for users who need to connect multiple devices simultaneously. The E8372 supports up to 16 Wi-Fi users at once, transforming a single 4G connection into a shared wireless network. huawei modem terminal
AT^U2DIAG=0 : Sets the device to "Modem Only" mode (disables virtual CD-ROM/Card Reader).
High-end Huawei CPEs feature advanced antenna designs, including 4x4 or 8x8 MIMO (Multiple-Input Multiple-Output) configurations. This is a significant competitive advantage, allowing higher throughput and stability in fringe coverage areas.
Reposition the router near a window. Consider purchasing an external 4G/5G antenna. See RSRP, RSSI, and SINR values for perfect
Start small. Run AT to say hello. Then AT^HCSQ? to see your true signal. Gradually explore band locking. And always keep a backup of your original configuration.

The process involves using AT commands through a serial interface. For many Huawei modems, the command AT^U2DIAG=0 or AT^SETPORT="FF; 1" accomplishes this transition. Tools like Huawei Modem Terminal software can facilitate this process for technically inclined users. AT^U2DIAG=0 : Sets the device to "Modem Only"
