Thank you for the response. I have updated the firmware to version 1.3.0; however, the modem continues to display several errors in the log. I stressed the modem by downloading large files from Steam, and the result is as follows:

The fan is not functioning! ...

I have already left a negative review on Amazon; a product at this price point should be of good quality, yet I find myself with a modem that has a firmware full of bugs and lacking precision. Based on what I read on the forum, I am not the only one who has reported these issues. Regarding the connection, it fluctuates between a maximum of 6.4 Mb/s and 200Kb/s, only to rise again. The CPU and memory load is within limits, around 50% for memory and 20% for CPU. I sincerely hope that you can resolve this issue promptly.

I have a question, this modem have a fan on internal case? When have a fan who control fan? It's hardware via thermal sensor or software when reach a High temperature? The temperature to start fan Is?. I do not want use a home made solution for this problem, i spent more money for good product, i want a solution. Tanks for reply and Sorry for orribile english. I'm electronic and automation technician, hvac qualified, this modem Is used for a supervisor sensor and control smart office via Cloud, for more week this modem Is out of connection and i have reach location for reset modem more and more again. 😔😔😔
