Hello! In general, my laptop has been working for many years and there are no problems with it. About 6 months ago, there was a problem that the WiFi was turned off, rarely. Now it has become very common. Moreover, this is important (!), wi-fi is turned off only after the laptop comes out of sleep mode (standby mode). At the same time, the touch button on/off wifi does not work; checking the equipment does not help. At the same time, the wifi adapter is marked as not installed in the Device Manager.

After that, the only option is to restart the laptop. After a reboot, I always see this screen:

After that, you have to turn off the laptop and turn it on again, and usually then everything is ok and there is wifi. However, sometimes I see such a screen:

And after such a screen, rebooting does not help. I try to restore the wifi in different ways, for example, through Resetting the network. Sometimes it helps. But sometimes the wi-fi adapter doesn't show up in the Device Manager at all.
In addition, I also tried to install other drivers manually downloaded from the Internet, in the hope that this would help, but it did not help. I removed Kaspersky anti-virus for a few days, but it didn't help either.
It turns out that it seems that the wifi adapter itself works and Windows sees it and the driver, too, but, as I said above, after the laptop comes out of Sleep mode (Standby mode), the wifi adapter is not detected by the system.
What can be done with all this? I'm already exhausted 🙂

P.S. it seems that not all photos are displayed, once again I attached them all here:

And yes, I used these links to perform the procedures, but nothing helped: https://support.hp.com/ru-ru/help/windows-10-support-center-computing#wireless and https://support.hp.com/ru-ru/document/c04756431
