Public bug reported:
RTL8723DE wifi+bluetooth adapter works only with one of the two
components enabled. This is a common bug encountered in all distros
after installing dkms module from lwfinger/rtlwifi_new repo. Ubuntu
20.04 fixed this in previous kernel releases (only distribution to do
so) and gave support for rtl8723de out of the box. Unfortunately, Bug
shows up again after doing sudo apt dist-upgrade. I presume this is a
kernel issue, as a new version was released recently. Since then,
bluetooth is able to scan for devices but cannot connect if wifi is
enabled first and vice versa.
