WiFi disappears after boot

Post by helpmeaccount »

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.

Turn power management off:

Code: Select all

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
Reboot

Also, be sure secure boot is still disabled.

Can you reinsert the card? Sometimes that will wake it up if it isn't totally dead.

Yes, it seems like that wifi card might be dead.
