no wifi on hp pavilion X360 no wirelless list on rfkill

[rsmpereira89]

Hi all
I installed recently 14.04 on a HP pavilion. I have tried other solutions without success, and I never seen such error in any other forum/post.

The wireless LAN is NOT listed with rfkill



~$ rfkill list all

0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no


~$ iwconfig
lo no wireless extensions.

eno1 no wireless extensions.



~$ ifconfig

[wildmanne39]

Sure you can take it out and paste the file in its place.
Thanks

[rsmpereira89]

Ok, any way

no wifi wet, does anyone knows if this was also a issue on ubuntu 15, I can simply downgrade my pc

[jeremy31]

For that chip you need to have Secure Boot disabled in BIOS, then

sudo apt-get install bcmwl-kernel-source

Reboot

How do I disable it, plus I have done the referent code before

[jeremy31]

Restart and the manual says to press the ESC and then F10 to get into BIOS, then search through the pages for Secure Boot settings, it may be in security or the boot page.

On my 16.04 computer I was able to enable secure boot with
sudo update-secureboot-policy --enable
So it may be possible to disable using terminal with
sudo update-secureboot-policy --disable
But since you have 14.04 it may not be possible

Good morning

Sorry It did not worked

Failed to request new MokSB state

[rsmpereira89]

Apparently I cannot disable security boot, no matter how many times I say yes. Any ideas?

[jeremy31]

You might be able to use mokutil to bypass the module verification
