Because the ZTE H2640 is primarily an ISP-managed gateway, the method for updating the firmware can vary based on your service provider. The Automated ISP Method (Recommended)
Before 2021, the H2640 had a reputation for spontaneous reboots under moderate load. The culprit? A memory leak in the old 3.10.x Linux kernel and a flawed Wi-Fi driver for the chipset.
ZTE's official stance is consistent with this. Their support website advises that users can visit their support portal to inquire about related information, but the embedded software is typically managed by the provider. This means the update process for the ZTE H2640 is passive from the user's perspective. The ISP is responsible for pushing updates to the devices on their network, often in the form of automatic, over-the-air updates. zte h2640 firmware 2021
