Hello @Solla-topee,
Thanks for your assistance, I will try to reply to all your questions.
- I have not modified the settings in the network adapter and when I cheked the option for power management it was as you shown in the picture, so that is not the problem. You can see it in screenshot:

- Thanks for the advice, but I already have different names for each band of the network router. The 2.4 is called "Jack" and the 5GHz is called "Jack.speed" I can share a picture with brand and model number of the router. Of all my devices, including several laptops, this is the only one who has issues connecting to Wifi.

So let me rephrase the problem. Whenever I turn on, reset or wake from sleep my computer the network adapter does not connect automatically to my Wifi signal. Sometimes after a few moments it connects, other times I have to manually select the Wifi and click on "Connect", and it can happen that it says "Can't not connect" so I have to restart the network adapter and try again. This is very annoying and my applications complain since they try to look for updates whenever Windows startup.
Whenever it finally connects to Wifi I have no problem with the internet connection, the problem comes before at the time of stablishing the connection.
I'm not sure what information about the motherboard you need, so I will just share a whole summary of my computer specs:

What else could be the problem? I will wait for your instructions.
