Wifi is not being detected on my HP 15 laptop with ryzen 3 processor. I am currently on kernel 419

I had re installed manjaro a few days back and kernel 5.3 was abandoned. Every thing was working pretty good on 5.3 kernel. Kernel 5.4 was giving pain in the ass for every task. S i swiched to kernel 4.19. But the problem of wifi has not been still solved.I tried chaging the drivers but of not use.

Still not working

You’re using the RTL8723DE wifi card, but you don’t have the driver for it. You need to install lwfinger’s rtw88 driver from github.

Open up terminal.
If you have access to ethernet, plug it in and follow the build instructions on the official github page. Scroll down below the file list.

If you don’t have access to ethernet, go to the github page, click on the green “Code” button at the top, and click “Download ZIP.” Extract that zip file into a folder, and put that folder on an empty flash drive. Boot into Manjaro and copy the folder from the flash drive to your home directory.
Open terminal and run the following commands:
cd rtw88
(replace rtw88 with the name of the folder you just copied)
make
sudo make install
And then reboot.
Everything should work when you boot up.
