WiFi disappears after boot
Tried : i have tried everything to do with bios like disabling secure boot, disabling ethernet , enabling network boot and also i have the working driver installed in it as it works it just happens after a reboot
it is not the first time happening it is happening for a month now i have changed my os 4 times from ubuntu to linux mint mate to linux mint cinnamon, right now i have linux mint mate with dual boot of ubuntu , the wifi was working for the past 15 days as i was not turning it off only but today the battery died and when i booted it the wifi and bluetooth was gone(wifi and bluetooth always goes out together)
conditions : If the wifi is working and then if you reboot the system wifi will be gone
it used to come back after i do something new in bios like last time i disabled the ethernet then booting brought back the wifi but now i just don't know what to do cause nothing is working i have tried enabling and disabling everything in BIOS setup but nothing work's
I have not updated the system after boot and any new install of whole system does not works as i have tried it ,it will just start randomly working
OS: Linux Mint 20.3 x86_64
Host: HP 250 G7 Notebook PC.

Re: WiFi disappears after boot
Install the 5.15 kernel in Update Manager, View, Linux Kernels. Reboot & test wifi.

Re: WiFi disappears after boot
didn't work
Re: WiFi disappears after boot
Turn power management off:
Reboot
Also, be sure secure boot is still disabled.
Code: Select all
sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
Also, be sure secure boot is still disabled.

Re: WiFi disappears after boot
the card is not even showing in devices and the code you pasted has nothing as output
Re: WiFi disappears after boot
Can you reinsert the card? Sometimes that will wake it up if it isn't totally dead.
Re: WiFi disappears after boot
Do you also have Windows installed on that machine?
