Why does the laptop stop seeing the wifi adapter after restarting the laptop?
A lot of letters, but it's still interesting to know your opinion.
Given:
Laptop HP 15-bw522ur
Two operating systems are installed: Manjaro Linux and Windows 10 Bottom
line:
the wifi network disappears, and the system does not see the wifi adapter at all when you have to restart the PC (by means of the system via start-reboot (windows), or from linux (by means of gui, or through the reboot terminal)
For example - if you go to reboot from Manjaro Linux, and then select Windows 10 in grub, then after loading into it the system does not see the wifi adapter - it is not in network connections, but in device manager In the "network adapters" section, the adapter hangs, but with a triangle, it says "the device cannot be started".
A similar situation if you reboot from Windows to Linux - the kernel does not see the adapter in any way.
The same thing happens if you reboot from Manjaro and boot back into it.
It helps to completely turn off the laptop and restart it, both in Linux and Windows.
Tried reinstalling systems multiple times, both Windows 10 and tested on multiple Linux distributions (Manjaro, OpenSUSE).
wifi adapter - REALTEK RTL8723DE.
On windows, the driver has been updated to the latest version. Under Linux, there is no driver in the standard delivery of the kernel, you have to download the rtlwifi_new driver from here and install it via dkms.
The BIOS has been updated to the latest version.
Question:
Has anyone encountered a similar problem? How did you try to decide? What are some ideas for solving this problem? Or is it easier to just change the wifi adapter to some other one, but I don’t know which one (and whether a third-party built-in adapter will start on HP is also a question, in Google they write that this feature can be locked on the BIOS level)?
If anything, my system configuration is .

I remember there were troubles that when you cut down the adapter in linux or put its "driver" incorrectly, then after rebooting into Windows, the adapter behaves exactly like this.
Helped:
1. do not touch it in linux, it works, so let it work.
2. Do not use the wifi off button on the keyboard while you are in linux.
Most likely, the adapter "remembers" a certain state set by the driver of another system and cannot reset it when initialized by another driver. When the power is turned off on the motherboard, all registers of the controller go to zero, and then, during initialization, they take on a state according to the principle "who first got up - that and slippers."
And when you reboot into the same axis, the problem persists?
