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:

   description: Network controller
   product: Wireless 8260
   vendor: Intel Corporation

   configuration: latency=0

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.

  • What is the Ubuntu version, kernel version? You need to install firmware. – Pilot6 Feb 02 '16 at 19:05
  • If you mean apt-get install linux-firmware-nonfree I just did that, but I still don't have a driver showing up configured under lshw -c network, or a wireless network – Al Christopher Feb 02 '16 at 22:38
  • Please answer the first question. It is nit about linux-firmware-nonfree, but about linux-firmware. You will need to update it depending on which verion is installed. – Pilot6 Feb 03 '16 at 04:42

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.

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.

    It depends on which Ubuntu version is installed. But OP does not tell us. I suspect OP has a non-ubuntu distro. – Pilot6 Feb 03 '16 at 08:44
  • As you're a reputation 1 user: if this answers your question, don't forget to click the grey ☑ under the "0" at the left of this text to accept it, which means "yes, this answer is valid"! – David Foerster Feb 03 '16 at 08:59
  • This won't work e.g. on 14.04. – Pilot6 Feb 03 '16 at 17:13
  • @Pilot6: I ran the command on 14.04.3. According to http://packages.ubuntu.com/search?searchon=contents&keywords=iwlwifi-8000C&mode=filename&suite=trusty-updates&arch=any the file is included in trusty-updates. I'll make a note in my question about that. – David Foerster Feb 03 '16 at 18:41
  • Firstly OP does not have any internet connection. And 3.19 kernel will not load firmware 13 – Pilot6 Feb 03 '16 at 18:45
  • @Pilot6: According to the question, the kernel is looking for, amongst others, iwlwifi-8000C-13.ucode, but I'm not intimate with the firmware loading process. I would like to keep the question until OP reveals more information about their system. In the mean time I'll refer to instructions on how to install packages without internet connection. – David Foerster Feb 03 '16 at 18:57
  • I see the point. This means that it is not an Ubuntu 3.19 kernel. It knows only 12 version of firmware. – Pilot6 Feb 03 '16 at 18:59
  • For wily and xenial there is no need to install anything. They have the correct module and firmware. – Pilot6 Feb 03 '16 at 19:00
