Kai-Heng Feng, I don't believe I've tried that, from the article you attached I'm not sure what going to a previous version would do to help as I have had this issue on several kernels since December 2018. I think the device team needs to modify the Intel driver for AMD B450 integrated WiFi compatibility, whether as an extended pci-e device or something a part of the chipset.
