Intel Corporation Wireless 8260 [8086:24f3] (rev 3a) [duplicate]

I installed Ubuntu on the new Lenovo miix 700 and haven't been able to get the wireless working. I used to have to remove and blacklist the ideapad_laptop wireless driver/controller with sudo modprobe -r ideapad_laptop and /etc/.d/blacklist-ideapad.conf to on the previous Lenovo miix model but didn't have luck doing that with this problem.

Kernel Version 3.19.0-25-generic

lshw -C network:

When I run ifconfig I don't get a wireless link

The problem was a lot like what was found in this post so I followed these steps.

Solution 1:

If you are using Ubuntu 14.04, you need to connect to internet by wire or a USB adapter and run in terminal:

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

and reboot.

This will install kernel 4.2 that supports this adapter and will update the firmware.

Solution 2:

Your system cannot find the firmware for your wireless adapter. apt-file search -x 'iwlwifi-8000C-.*\.ucode' returns:

linux-firmware: /lib/firmware/iwlwifi-8000C-13.ucode

The most likely solution to your issue seems to be to install that package, if you can find another method to connect your computer to the internet:

sudo apt-get install linux-firmware

Otherwise you can perform an offline installation.

Then you need to reload the wireless driver module or reboot the computer.

Edit: This only works on Trusty (with the trusty-updates repository enabled).

For Wily and the upcoming Xenial the adapter will work out-of the-box.
