Currently using Ubuntu 18.04, and my wireless driver is not being detected.

I've included a wireless diagnosis log.

$ dmesg | grep iwl

sudo modprobe iwlwifi returns no output.

  • I expect that it wants but is missing firmware. Let's try to find out which. Please edit your question to add the result of two terminal commands: sudo modprobe iwlwifi and also: dmesg | grep iwl Welcome to Ask Ubuntu. – chili555 May 23 '18 at 20:13
  • @chili555: OP added the requested info and it looks like the driver found a firmware and loaded it happily. – David Foerster May 29 '18 at 1:09

I noticed this morning that Update Manager installed a later version of the package linux-firmware. I suggest that you obtain a temporary internet connection by ethernet, tethered or whatever means possible and open a terminal and do:

sudo apt update
sudo apt upgrade

I suspect that linux-firmware will be upgraded. After the upgrade, my firmware files include:

iwlwifi-9000-pu-b0-jf-b0-33.ucode
iwlwifi-9000-pu-b0-jf-b0-34.ucode
iwlwifi-9000-pu-b0-jf-b0-38.ucode

Reboot so that -38 loads instead of -34 as before. Check the log:

dmesg | grep iwl

Is the alarming message gone?

iwlwifi 0000:00:14.3: Failed to start INIT ucode: -110

Your wireless should be working now.

  • gave that a go same error messages - Im suspecting it could be a hardware problem - tried using the wifi module on windows as well and seems like its failing as well – Hyun Kim May 30 '18 at 12:21
  • I'm having this issue in Ubuntu live environment, but for me, it works fine in Windows, I have a connection, but installer/live environment cannot connect to internet 9560. I'm hesitant to install if I can't get wi fi working, any ideas? – edencorbin Jul 10 '18 at 22:31
  • @edencorbin Please start your own new question. I'll be happy to help. – chili555 Jul 11 '18 at 1:18

Someone I know had her Intel AC Wireless 9560 stop working randomly during the day (Ubuntu 18.04.2). After investigating the dmesg output, checking out the NetworkManager service, reinstalling linux-firmware, rebooting, etc., we tried loading up Windows 10 on the second partition. Even Windows 10 could not find the wireless.

I've seen a few forums mentioning this particular Intel wireless card model. While this may be unhelpful, it's possible your card is broken; you may want to invest in a usb wifi or use ethernet and see if the card can be replaced (or do it yourself) [with another model].

She updated the BIOS and it started working again.

  1. You should be sure then your HW support this stuff. It requires the newest HW.
  2. Despite this stuff officially is supported since kernel 4.14+, by the fact you will avoid a lot of issues by using 4.16+ and the newest firmware.
