Most modern ZTE routers (especially 5G models like MC801A) support automatic or manual OTA updates.
Here is how to handle it properly.
New firmware may have reset QoS (Quality of Service) or MTU settings. Fix: Reboot your modem (ONT) from your ISP. Then, in ZTE router settings, disable QoS and set MTU to 1500 (or 1492 for PPPoE).
Open a web browser and enter the router’s gateway IP address. Common ZTE defaults include 192.168.1.1 or 192.168.0.1 .
