Does anybody know how to configure wifi on Lenovo ThinkPad s440 on Ubuntu 12.04 LTS? I can't configure it even with LAN. But anyway, wifi is the first thing I need. I can't find any driver for linux. As I see it from (official specs link) Ubuntu uses Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller to establish network. Can anybody suggest a solution? A driver, a way to configure wifi or anything?..

could you post the output of lspci? –  bersch Jan 24 at 23:13
Sure! Edited the post. –  boldnik Jan 24 at 23:19
you need to load the iwlwifi kernel module for wifi, just add iwlwifi to /etc/modules . then run modprobe iwlwifi; you'll see your new device with ifconfig -a. Your wifi hardware is Intel 7260. In some cases you need also the firmware, if the module wont load. See also your dmesg output. –  bersch Jan 24 at 23:52
Your ethernet (lan) module seems to be r8169, try to follow like explained before. –  bersch Jan 25 at 0:14
Thanks a lot! Really helpful info. I will try this out because LTS version is prefered over 3-months support. –  boldnik Jan 25 at 0:20

Tried install Ubuntu 13.10. It worked. Not the way I actually wanted to setup the wireless, but it worked. Solution found here

Unfortunately, 13.10 didn't recognize my video card and couldn't load graphics. So, I finally found solution and reposted it here

So, steps (by chili555) are: """ I suggest you download this to your desktop: http://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.11-rc3/backports-3.11-rc3-1.tar.bz2 Right-click it and select 'Extract Here.' Now open a terminal and do:

cd Desktop/backports-3.11-rc3-1/
make defconfig-iwlwifi
sudo make install

Now download the required firmware here: https://dl.dropboxusercontent.com/u/58267392/iwlwifi-7260-7.ucode.zip Please download it to your desktop. Right-click and select 'Extract Here.' Now open a terminal and do:

sudo cp Desktop/iwlwifi-7260-7.ucode /lib/firmware/
sudo modprobe -r iwldvm  <--If it is not loaded, OK, please proceed
sudo modprobe -r iwlwifi <--If it is not loaded, OK, please proceed
sudo modprobe iwlwifi

Your wireless should now be working. """ Thanks!
