Ubuntu – Install Intel AC 8260 wireless drivers offline

14.04driversintel-wirelessiwlwifinetworking

As my laptop does not have Ethernet port, to set up wireless, I need to install drivers offline.

My Ubuntu version is 14.04.3, and kernel version is 3.19.0-25-generic.

Output of the command:
lspci -knn | grep Net -A2:

is:

 01:00.0 Network controller [0280]: Intel Corporation Wireless 8260 [8086:24f3] (rev 3a)
    Subsystem: Intel Corporation Dual Band Wireless-AC 8260 [8086:0010]

Since here:

it is suggested to try following these steps:

Intel wireless 8260 – unclaimed network

I tried, but without any success.

Now I am not sure what to try next. I am not Ubuntu expert, and would appreciate any help.

Thanks a lot in advance.

The problem is that kernel 3.19 does not support firmware version 13 that you can get for Ubuntu 14.04.

The easiest way to do offline is to install Ubuntu 15.10.

The adapter should work without any effort.

You can get it working on Ubuntu 14.04, but you will need to upgrade the kernel and the firmware. I can give you directions.

But you will have to download some packages using another computer and then install them to Ubuntu.

Install to Ubuntu 14.04

Copy the files to your home folder and run in terminal:

sudo dpkg -i linux*.deb

Reboot and test the Wi-Fi.
