I have been trying to find out if it is possible to activate Wi-Fi in Ubuntu without the need for the "FN + F4" key combination, since in Windows this combination was not necessary for Wi-Fi to be automatically activated.
I visited several specialized forums, but I did not get a satisfactory answer. Below I leave my learning and attempts.
This is the version of my system:
Distributor ID: UbuntuDescription: Ubuntu 22.04.4 LTSRelease: 22.04Codename: jammy
1 - As suggested by forums, I listed the networks using the "RF-KILL" command. I identified that the hardware was blocked, as expected
rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes
2 - I then tried to unblock all of them using the following command. However, without success.
rfkill unblock all
3 - Reload the kernel module of the Wi-Fi card, first trying to find out which module it was.
lspci | grep -i network sudo modprobe -r module_name sudo modprobe module_name
4 - Unblock via ACPI, adding the second line of code. Don't forget to update the document.
sudo nano /etc/default/grub - GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux" sudo update-grub sudo reboot
5 - All the forums I searched before opening this question.
