In short, I recently installed Ubuntu 20.04 to breathe new life into my 2 in 1 acer aspire switch one 10 (SW1-011), and everything seems to work properly (with a few minor exceptions) but the real problem is that the wifi card is not being detected.
The model is RTL8723BS, which includes both bluetooth and wifi, working on a SDIO interface as far as I know. Bluetooth works correctly, but the wifi interface is not even listed anywhere.
iwconfig shows "no wireless extensions"
rfkill list all shows only bluetooth
sudo lshw -C network shows only an ethernet interface
There is no physical switch for wireless nor bluetooth, neither a BIOS option. Secure boot is disabled.
Here I found some old topics about this, and they all referred to the https://github.com/hadess/rtl8723bs repository, but since then the drivers have been merged into the kernel, and fact I can see them in /lib/firmware/rtlwifi/.
This is the output of dmesg | grep -i rtl
