after making all the updates after the first installation and restarting the system, I can no longer activate the wifi or rather I can activate / deactivate it but in the settings screen it always tells me that it is deactivated. I have a Matebook d14 2020 with Ryzen 7, how can I fix? I attach a image of the error/bug
I have the same problem and I found the solution myself.
Apparently the problem is due to the Realtek 8822c video card driver (which is missing the rtw8822c_wow_fw.bin file needed to correctly load the rtw8822c_wow_fw.bin driver)
The solution is to download the latest version of linux-firmware from:
Extract and copy the contents of the rtw88 folder to /lib/firmware/rtw88
Restart the operating system.
When restarting the wifi card will be fully functional!
