System Firmware
- Make sure your system kernel is above 5.4. Do not use sudo update to upgrade the Raspberry Pi to the latest version. This will upgrade the kernel version to a version higher than the current firmware and it will not be recognized.
- It is recommended to use the more convenient RNDIS dial.
- Can burn the latest Raspberry Pi Raspbian system and reconfigure NDIS dial-up.
- Or use the image that has been configured with the driver. NDIS dial-up and start automatically. Raspbian system image (with the driver installed).
{{{5}}}
The new driver may not be compatible with some WIN7 systems, you can try with the old driver:
- SIM7600-Driver.7z
- SIM7600X-Driver.7z
- Follow the steps below to install the driver:
1. Download the driver: SIM7600X-Driver.7z.
