Ubuntu 18.04 cannot recognize Intel Wireless-AC 9260

Question

I just install Ubuntu 18.04 yesterday, and it seems like Ubuntu cannot detect wifi adapter. The card is working on Windows, so it should not be a problem. I also have the same firmware as the one stated on Intel website (iwlwifi-9260-th-a0-jf-a0-34.ucode). Checking the log, I see iwlwifi failed with error -110.

Any idea how to troubleshoot this issue?

Thanks,

Below is the details log:

Hi! Welcome to AskUbuntu! Can you also include the output of iwconfig? Be careful to redact anything that may be traceable like ESSIDs or MAC addresses with Xs. Thanks! — tudor -Reinstate Monica-, Oct 13 '18 at 11:28
Thanks. I have updated the iwconfig output in the question. It shows no wireless extensions. — hgminh, Oct 13 '18 at 12:21
Hey @hgminh did you manage to get it working? I am currently struggling with a laptop having the 9260 Intel card, and can't get it to work.
What I've tried:

Standard 18.04 ubuntu

Reinstall linux-firmware

Copy Intel ucode drivers to /lib/firmware from here and the referenced newer drivers

Updated to 19.04

Tried the same

Currently I am going to try 16.04 to see if downgrading helps.

If you got it to work, could you please point me in the righ direction? — Matyas, Aug 10 '19 at 14:41
@Matyas Unfortunately, the only way I manage to make it work is to boot into Windows and then restart to Ubuntu. The issue is tracked here. It is not likely to be resolved anytime soon :( — hgminh, Aug 13 '19 at 04:00
Thanks. will post this as an answer below, for visibility, so others come to a conclusion quicker. — Matyas, Aug 13 '19 at 18:03

It is a problem with fast startup mode of Windows. I think because in that mode, Windows keeps the wireless adapter for itself when shut down. hence Linux cannot detect it.

Just go into Settings > Power & Sleep > Choose what power button does > Shut down setting > uncheck the Turn on fast startup > save change and it will work.

Someone explained how to fix it without booting into Windows here, I didn't try it: https://bugzilla.kernel.org/show_bug.cgi?id=201319#c55 – Sam Watkins May 24 '21 at 14:56
It would be worth adding this into the installers, to detect this circumstance and either fix it or warn the user about it... Does this happen for other wifi or only iwlwifi? – Sam Watkins May 24 '21 at 15:38
Sounds like a bad joke, but here's my short story: I made a fresh install of different Linux distributions erasing the whole drive (that initially contained Windows). Wi-Fi didn't work - on installed versions or live USB drives. I thought it's crazy but I installed Windows and decided to turn off that fast startup feature in it (on Windows Wi-Fi worked well). Didn't work. So I turned off Wi-Fi on Windows. And that helped!!! Wi-Fi started working on live USB distributions and it's working also after Linux was installed on an erased (again) drive. Magic. It's hard not to love Windows... – Adrian Bienias Nov 05 '21 at 10:00

The Intel 9260-AC Wireless Chipset doesn't work in newer Linux kernels (ex: Ubuntu 18.04).

Here is the kernel bugreport that can be checked for the status.

In my case this was affecting a freshly bought: Lenovo IdeaPad/Yoga S730.

The solution for me was to install Ubuntu 16.04 with an older kernel, which worked without any issue

Edit 2021-01-18

The wireless adapter in the IdeaPad/Yoga S730 is working fine on ubuntu 20.04

iwlwifi-9260-th-b0-jf-b0-34.ucode is included in the package linux-firmware in Ubuntu Bionic.

Try upgrading or reinstalling the package.

apt-get --reinstall install linux-firmware

Don't try to manually install from an archive provided by Intel. Always try to find a package that provides the driver if possible.

Thanks. But after I reinstall firmware, the issue stays the same. I also tried to update kernel to 4.18 which use newer firmware (iwlwifi-9260-th-b0-jf-b0-38.ucode), but got the same result. – hgminh Oct 13 '18 at 13:20

I just want to reach back in time from up here in THE DISTANT FUTURE, Jan 2020, and say I had the same problem with an Asus Zenith Extreme Alpha motherboard with the Wireless-AC 9260 not being recognized by Ubuntu 18.04.

I tried downgrading to 16.04, to no avail. Also tried updating the firmware; nope.

But the wired Ethernet worked, and a simple dist-upgrade did the trick for me.

I recently had the same issue in Kubuntu 18.04. I don't have any windows installed, so no fast bootup or issues like that. But whenever I shut down, I used to use the buttons from the start menu (Win Key -> Leave -> Shut Down) to shut down. I suspect that might not be shutting down my system well. So I shut down the PC completely using Linux's usual shutdown command:

sudo shutdown -h now

I haven't looked into what command Kubuntu runs to turn off the system, but once I turned off using the above command and turned it back on, the error disappeared, and the wifi started working again.

Had same problem, this solved it for me. My laptop "powered off" after closing the lid and the battery went empty. Sometimes closing the lid does not let my laptop go into sleep mode properly and it eventualy shuts down. Thanks! — devunder, May 22 '22 at 09:06

Yeah, seems like it might be a bug (intel driver). The card itself works but on the Additional Drivers tab it shows up as greyed out.

Windows' fast startup can cause it but not only !

Also Windows Hibernate causes this problem - somehow when Windows is not shut down completely it blocks the Wifi adapter..
