• Change WiFi Channel: Use the HiLink interface (192.168.8.1) to avoid interference.
• Enable IP Passthrough (Bridge Mode): Some drivers allow the E5372s to act as a pure modem, letting your router handle WAN duties. Use the command AT^NDISDUP=1,1,"internet" to bridge.

2. The Role of "Drivers" in a Wi-Fi Modem

A common point of confusion for users is whether the E5372s actually requires a driver.

• Wi-Fi Mode: If you connect to the device via Wi-Fi (using the SSID and password printed on the sticker under the battery), you do not need a driver. It functions just like any other Wi-Fi router.
• USB Tethering Mode: If you plug the device into a PC via USB to charge it and use it as a wired network connection, the computer needs to recognize it as a network adapter. This is where the "driver" comes in.

When connected via USB, the E5372s usually presents itself to the computer as a HiLink device. It mounts a virtual CD drive containing the driver software, which automatically installs on most Windows systems.

Where to Safely Download the Huawei E5372s Driver

Warning: Many third-party websites promise "free driver downloads" but bundle malware, adware, or outdated firmware. Do not use driver updater software that you find via pop-up ads.

Here are the only safe sources:

1. Official Huawei Support (Archived): Huawei removed its consumer download portal, but the enterprise archive still holds files. Look for "Huawei Firmware Finder" or official carrier repositories (e.g., Vodafone, T-Mobile, 3UK) that released the E5372s.
2. The Huawei Mobile Partner Suite (Version 23.009.05.03.00): This is the gold standard. It includes the complete driver set for all Huawei E3xx, E5xx, and E537x modems. The specific driver for the E5372s is baked inside the Drivers folder of this suite.
3. The "AutoRun" CD-ROM: When you first plug the E5372s into a Windows PC with no drivers, it typically mounts a virtual CD-ROM drive. Inside is an Autorun.exe or Setup.exe file. This contains the official Microsoft-certified driver for that specific device. This is the safest method.

Critical Version Note: Ensure you are downloading drivers for the E5372s, not the E5372, E5373, or E5377. While they share similar chipsets (HiSilicon Balong), the USB PID (Product ID) codes differ. Using the wrong driver may cause a Code 10 error (Device cannot start).
