The most common method is OTA. The router can automatically check for and apply updates. Users can also trigger a manual check from the router's web interface, typically found under Settings > Device > Online Update .
Ensure your SIM card is active, as some updates are pushed based on the carrier network.
By following this guide, you are well-equipped to manage, update, and troubleshoot the firmware on your Huawei 5G CPE Pro 2 (H122-373), ensuring reliable and high-performance connectivity for years to come.
Running outdated firmware on your H122-373 can lead to slower speeds, dropped connections, and potential security vulnerabilities.
Using unofficial firmware can overheat the 5G radio, brick the device, or violate your ISP’s terms of service. huawei h122-373 firmware
: Huawei clearly designed this firmware for ISPs, not end users. The missing features aren’t bugs—they’re strategic omissions to push you toward expensive business 5G routers. If you can find an open-market unit (no carrier logo on the box), flash the generic firmware, and don’t need IPv6 LAN, it’s one of the best 5G CPEs out there. Otherwise, look at ZTE MC801A or even a 5G modem + OpenWrt router.
Before diving into firmware specifics, it's important to understand why this router is so popular. The H122-373 is a 5G router that supports Wi-Fi 6, offering theoretical peak speeds of up to [0†L25-L26]. Powered by Huawei's Balong 5000 chipset, it supports advanced features like 4x4 MIMO and carrier aggregation to maximize network performance [0†L29-L31].

If your power goes out during an update, the router may get stuck with a solid red light or constantly restart. You can try a hard factory reset: The most common method is OTA
Firmware is the built-in software that controls how your router's hardware operates. Running outdated firmware can limit your device's capabilities. Updating your H122-373 firmware provides three main benefits:
This document explains how to find, verify, and install firmware for the Huawei H122-373 (fiber ONT / residential gateway). It covers locating official firmware, preparing for the update, backing up settings, performing the upgrade via web UI and TR-069/ACS where applicable, and troubleshooting common issues.
If an OTA update fails or a user wants to try a specific version, a manual update can be performed by uploading a firmware file locally. This is done via the router's web interface by directing it to a previously downloaded .bin or .zip file.
I can:
By understanding the firmware ecosystem for the H122-373, you can make informed decisions that balance stability, features, and security. The router is capable of delivering exceptional 5G performance for years to come — as long as you treat its software with the respect it deserves.
If this fails, you may need to use advanced multilateral tools like to push the firmware via an Ethernet cable. De-branding and Custom Firmware (Modems/Flashing)
If you cannot manually select your 4G/5G bands, your current carrier-customized firmware has likely locked these settings.
Firmware may have changed modem NVRAM settings or band preferences. Fix: Navigate to Device Settings > Mobile Network > Search Networks manually. Re-enter APN information. If still broken, roll back to previous firmware. Ensure your SIM card is active, as some
