Dear _nero_,

Another way to disable the aforementioned HP module is using the following command in terminal:

sudo rmmod hp-wmi

Please let me know if this solves your problem.

not working ,.

It says use hardware button but hardware button does not working , is there any other way?

is there any other way by editing  kernal or source code .

Dear _nero_,

I am sorry your wifi is still not working, I would like to let you run the following command:

sudo rmmod hp-wmi

sudo nmcli networking on

This is a combination between an aforementioned command which toggles a unix conflicting HP module off and  then force switches airplane mode on from the command line.

As for the editing of the kernal or source code I am unsure.

Let me know if the commands worked.

hi L.J. de Boer

After reinstalling wifi drivers its started working normally , and i have also updated the bios, may be bios might caused this .

thanks for your support.
