After installing 3.8.11 on my laptop hp 15-db0020nf , wifi isn't work out the box . To installing rlt 8723de i follows the page GitHub - smlinux/rtl8723de: Realtek RTL8723DE module for Linux . It works now. Happy!
@Thanatermesis maybe this driver should be included?
@Norady welcome to the forum and thanks for the tip
This is strange as this RTL8723de module should be built into kernel 5.3 and up.
What kernel were you using there, the default 5.4 or the older 4.19 ?
Anyway, glad it works.
