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?


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! – tu-Reinstate Monica-dor duh 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: 1. Standard 18.04 ubuntu 1. Reinstall linux-firmware 1. Copy Intel ucode drivers to /lib/firmware from here and the referenced newer drivers 1. Updated to 19.04 1. Tried the same 1. 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 4:00
  • 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.

  • hmm, could be it, let me try later today. – hgminh Oct 23 '19 at 8:32

  • Man win fastboot is causing me so many problems with Ubuntu - thanks for pointing out how to disable it! – Tejaswi Yerukalapudi Apr 1 '20 at 3:37

    Great. Worked with Arch Linux too. Windows causing problems even when it's not running. – Joshua Detwiler May 6 '20 at 15:58

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

    Thanks, it is also reported at bugzilla. – hgminh Oct 14 '18 at 8:39

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


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.


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.
