LTE7490-M904

Hi

I am just wondering is the DFOTA module update (LTE Module Version) different to the firmware update? I have LTE Module Version: EG18EAPAR01A08M4G does this need to be updated? If so I how do I update it? I have the latest firmware update of V1.00(ABQY.9)C0 

Thank you

Hi @IanDe,

The DFOTA (Delta Firmware Over-The-Air) module update for the LTE module and the main firmware update for your LTE7490-M904 are distinct. The LTE module firmware (e.g., EG18EAPAR01A08M4G) pertains specifically to the cellular modem component, while the main device firmware (V1.00(ABQY.9)C0) manages the overall router functionalities.

Regarding your LTE Module Version EG18EAPAR01A08M4G, it's generally recommended to avoid LTE (radio) module firmware updates unless absolutely necessary, as they can sometimes reduce device performance or are tailored to specific regions and network settings. If your device is stable, updating the device firmware only is usually sufficient.

If you encounter specific issues that you believe could be resolved by an LTE module update, please provide further details. Updates for the LTE module are typically handled separately and may involve different procedures or files than the main firmware.

To help us investigate further, please provide the following information:

• Current LTE Module Version: EG18EAPAR01A08M4G (You have already provided this).
• Current Firmware Version: V1.00(ABQY.9)C0 (You have already provided this).
• Detailed description of any issues you are experiencing: This will help us determine if a module update is indeed necessary.
• Where was the LTE7490-M904 purchased? (e.g., directly from Zyxel, a telecom company, or an alternative vendor). This is important as updates may be provided through different channels.
• Screenshots of the Cellular WAN Status page from the device's web interface. This can provide valuable diagnostic information.
