I am a Chinese, and I encountered a problem when using em7430. Please help me to solve it. My English level is limited, and the content is translated through translation software. Now, the 7430 module can be integrated into recognition, but there is no service in reality. If I update the firmware, there will be a driver that cannot be installed and updated normally. What should I do. ---

我可以讲中文吗？ 目前的情况是我有dell的dw5816e模块，通过M.2转usb，在电脑上使用，设备管理器中网络适配器可以识别的em7430，但是一直显示无服务，设备管理器内没有调制解调器，使用的Windows11系统，想通过升级官方固件变成通用版的em7430，但是升级失败，目前em7430可以识别，但是无服务，没有调制解调器，也不能升级，我想是否可以通过升级的方式将dw5816e变成通用的em7430，从而在电脑上正常使用。 ---
