Ubuntu 18.04: No WiFi adapter found - secure boot disabled

Question

I am using Lenovo T460 running 18.04.2 and kernel Linux 4.15.0-46-generic. The wireless settings shows "No Wi-Fi adapter found". I've disabled secure boot from start. I've tried to enable Wi-Fi again like in this post with no result.

$ lspci -nnk | grep -A2 0280

04:00.0 Network controller [0280]: Intel Corporation Wireless 8260 [8086:24f3] (rev 3a)
    Subsystem: Intel Corporation Wireless 8260 [8086:0130]

$ lsb_release -a

I've done another apt update and a firmware update.

In the end the solution I think should be in some BIOS setting or reinstalling the driver (maybe from here?)

If I restart with the previous kernel, 4.15.0-45, the problem remains, with a different version of the module and a shorter error log.

After renaming last two modules downloaded from Intel site, the kernel loads the previous one, but it fails too:

Even from another distro, Fedora live, I have the same error. So I think or is something about the BIOS or the wifi card was damaged in some way..

Update: Tried also disabling power management as suggested here but it didn't work

sudo gedit /etc/pm/config.d/blacklist
sudo chmod -x /usr/lib/pm-utils/power.d/wireless

SOLVED: I changed the wireless card (with AC 8265)

Solution 1

Lets first check the file system...

• boot to a Ubuntu Live DVD/USB
• open a terminal window
• type sudo fdisk -l
• identify the /dev/XXXX device name for your "Linux Filesystem"
• type sudo fsck -f /dev/XXXX # replacing XXXX with the number you found earlier
• repeat the fsck command if there were errors
• type reboot

Lets remove the incorrect drivers, and try and reinstall the firmware files...

sudo dkms remove rtlwifi-new/0.6 --all # remove incorrect dkms driver

sudo apt-get purge bcmwl-kernel-source # remove incorrect broadcom driver

sudo apt-get update # update the software database

sudo apt-get install --reinstall linux-firmware # reinstall firmware

reboot # reboot the computer

Recheck wireless operation.

Update #1:

Found hugely bloated Intel firmware at /lib/firmware/iwlwifi-8000C-34.ucode and /lib/firmware/iwlwifi-8000C-36.ucode. Removed them and reinstalled linux-firmware, and the code sizes look good now, but it still doesn't work.

Update #2:

Booting Fedora Live results in the same wireless errors that we see with Ubuntu. Suspect a problem with the wi-fi card. It may need re-seating or replacement.

Solution 2

This happened to me one time. It turns out I disabled Intel Platform Trust Technology in BIOS. Making sure that was enabled fixed my issue.

Hi, I'm in office now and I can't use a live Ubuntu, why is a fsck necessary? Anyway I followed the other steps to remove wrong drivers and reinstall firmware, but nothing changed. Which is strange because at least dmesg should have shown less errors

[Boris Hamanov]

@bastaPasta you fsck to make sure there's no file system corruption.

[tuxErrante]

Do you know how to replace it with Intel drivers (iwlwifi-8000C-36.ucode) or with a backport? (askubuntu.com/a/706030/259316). After I copied the Intel 36.ucode in /lib/firmware it has failed loading 34.0.1 again looking at dmsg

[Boris Hamanov]

Try booting to the prior kernel and see if you still have the same problem. Report back.

[tuxErrante]

Tried unsuccessfully. Details in the post

[Boris Hamanov]

Boot to a Ubuntu Live DVD/USB and see if it works. Report back.

[Boris Hamanov]

Edit your question and show me cat /etc/NetworkManager/NetworkManager.conf and cat /etc/netplan/*.yaml

[Boris Hamanov]

@bastaPasta Oh, I think I found the problem. Go to /lib/firmware/ and rename iwlwifi-8000C-34 and -36 to iwlwifi-8000C-34.HOLD and -36.HOLD and reboot. Recheck wireless. If that doesn't work then sudo apt-get install --reinstall linux-firmware again, reboot and retest. Let me know if I need to update my answer.

[tuxErrante]

The renaming didn't work, see original post. I even tried woth a usb Ubuntu 18.10 and there were the same problem. I'm going to try the reinstall

[Boris Hamanov]

@bastaPasta delete the two .HOLD files and reinstall linux-firmware. Then ls -al /lib/firmware/iwlwifi-8000C-*.

[tuxErrante]

I've immediately searched it full of hope, but there is nothing with a similar name. I'm going to search if on my Lenovo there is something equivalent

[Boris Hamanov]

@bastaPasta see intel.com/content/www/us/en/support/articles/000007452/…

[tuxErrante]

How much is dangerous to restore factory keys?

[Boris Hamanov]

@bastaPasta It might break stuff... like Windows?

[tuxErrante]

I have only Ubuntu on this laptop

[Boris Hamanov]

@bastaPasta I'd wait to see chili555's answer to my last comments. Is your TPM enabled in your BIOS?

[tuxErrante]

Updated with some BIOS photo, since I couldn't find that "Intel Platform Trust"

[tuxErrante]

Updated with some BIOS photo, since I couldn't find that "Intel Platform Trust"

[tuxErrante]

I found that option under Security chip selection and it is already on PTT which use Intel platform trusted technology
