Intel wireless 8260 - unclaimed network

Question

I have a thinkpad yoga 14, and I installed Ubuntu 15.10 on it.

Wireless isn't working.

sudo lshw -c network has (for the relevant device):

zck@my-computer:~/Downloads$ sudo lshw -c network
  *-network UNCLAIMED     
       description: Network controller
       product: Wireless 8260
       vendor: Intel Corporation

       capabilities: pm msi pciexpress cap_list
       configuration: latency=0
       resources: memory:d2a00000-d2a01fff

I downloaded the Intel Wireless WiFi Link 8260 AC Adapter, and untarred it, so now I have iwlwifi-8000C-15.ucode, and I put it in /lib/firmware as it says, but I'm not sure how to hook that up to iwlwifi, or even if that's the correct thing to do.

additional requested commands:

Solution 1

Your device, Intel Corporation Wireless 8260 [8086:24f3] (rev 3a), Subsystem: Intel Corporation Device [8086:1130] is not yet covered by the driver iwlwifi. Several variations are covered, but not the exact pci.id and subsystem combination that you have. Let's try to add it.

Please download this file to your desktop: https://www.kernel.org/pub/linux/kernel/projects/backports/2015/09/23/backports-20150923.tar.gz Right-click it and select 'Extract Here.' Drill down to drivers > net > wireless > iwlwifi > pcie. Open the file drv.c with any text editor, like gedit, nano or kate. Scroll down to line 428. Please notice that your pci.id ending in 24F3 hasn't a corresponding subsystem of 1130. 24F4 has an 1130, but not your 24F3. Let's just change it. Change line 428 from:

{IWL_PCI_DEVICE(0x24F4, 0x1130, iwl8260_2ac_cfg)},

To read instead:

{IWL_PCI_DEVICE(0x24F3, 0x1130, iwl8260_2ac_cfg)},

Spacing, punctuation, brackets, etc. are crucial and must be perfect. Proofread carefully, save and close the text editor. Now:

cd ~/Desktop/backports-20150923
make clean
make defconfig-iwlwifi
make
sudo make install

Reboot. Any improvement?

You have compiled the driver for your currently installed kernel version only. When Update Manager installs a later linux-image, after the required reboot, please recompile:

cd ~/Desktop/backports-20150923
make clean
make defconfig-iwlwifi
make
sudo make install

Please retain the files and these instructions for that time.

Solution 2

To get this wireless adapter work in Ubuntu 15.10 you need to install firmware by running

wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.156_all.deb
sudo dpkg -i linux-firmware_1.156_all.deb

For Ubuntu 14.04 you need also to upgrade the kernel by

sudo apt-get install linux-generic-lts-wily

Solution 3

chili555's answer was certainly correct, but I haven't tested that. I'd just like to add that support is included in updated kernels for Ubuntu 15.10. When you're installing Ubuntu, wifi won't work to get you connected, but simply use a cable to get updates. Your wifi will work after a reboot. After updates, this worked out of the box on a Thinkpad P50.

So there's no need to download, edit and compile anything any more.

Please edit your question to add the result of these terminal commands: lspci -nn | grep 0280 and also: sudo modprobe iwlwifi (this may produce nothing) and finally: dmesg | grep iwl I am only looking for any messages related to firmware. Welcome to askubuntu.

[Admin]

@chili555 Thanks. I've updated the post with those three commands, and (since I got a hardwired connection), the verbatim output of lshw.

[Admin]

Please pardon my mis-step; I actually needed: lspci -nnk | grep 0280 -A2 . Sorry.

[Admin]

No worries. I updated the question with the new lcpci results. Also interesting is that dmesg | grep iwl now has results, which I've also put into the post.

[Admin]

I am writing an answer; it will take a few minutes. Please be patient.

[zck]

This did it. Thanks so much for your help. That sucks that there are different subsystems; I figured that the 8260 number was what I needed to check on.

[chili555]

Please see my edit above.

[zck]

Ah, that's interesting. Any idea when the driver will support this pci.id and subsystem combination? Any way I can help make that happen?

[Pilot6]

@zck After you create a bug report, please ping me. I will send a patch upstream. Someone needs to do it. This way it will get to Ubuntu kernels sometime.

[zck]

Interesting. Does that mean everything will work in a new kernel release? Or should I still report a bug as mentioned above?

[fariza]

This modification was done by hand, and I didn't see any bug report for it, so you should report it. The wireless driver modification is one thing, and other is the ideapad_laptop, both are related but belong to a two different bug reports

[chili555]

@Marplesoft Perhaps,but I'd have no idea how.

[Pilot6]

It is fixed in the wily kernel.

[chili555]

It is fixed in 4.2.0-17 and perhaps others in Wily's 4.2 series.

[xhudik]

@chili555 wonderful, this worked also on my Debian Jessie - thanks a lot!!!

[xhudik]

small additional comment: chili555 answer won't work unless you have done this: download firmware (intel.com/content/www/us/en/support/network-and-i-o/…) copy iwlwifi-8000C-13.ucode into /lib/firmware.

[pesho hristov]

I'm using BunsenLabs linux on Lenovo T560 and had the same problem. First tried to copy all the ucode files from here - github.com/OpenELEC/iwlwifi-firmware/tree/master/firmware - to /lib/firmware, but no success. Then did the steps in this answer and all is fine now. Thank you :)
