I have installed Ubuntu 12.04 LTS on my Lenovo T440s, but I can't get the wireless to work. The adapter is a Intel Wireless 7260, as shown here: http://www.ubuntu.com/certification/hardware/201308-14073/components/

I installed while having a network cable plugged in, so all updates were also downloaded/installed during installation.

When I press on the network-"half circle" in the top, right corner it just says "not enabled" at the wireless. What is wrong here, it seems like 12.04 should support it from this.

I have the T440s and Ubuntu 12.04 is running wonderfully. But to get it running smoothly and also the wireless adapter, you will need to have the newer Linux kernel installed.

So make sure you are connected to the internet (by using Ethernet or a phone tethering). Then run the following command in terminal;

sudo apt-get update
sudo apt-get install linux-generic-lts-saucy

This will install the latest 3.11 kernel. Once it's done (only when it's done), restart your laptop.

Also, I just noticed that the 12.04.4 version was released very recently. With that version the above is no longer needed and everything should work out of the box. So to all new people installing Ubuntu 12.04 on a T440s, please make sure to have the latest version.

You may get it from here: Download Ubuntu

Please search for hardware-drivers or Drivers in menu open that up and keep your cabled network connected, you will see your wireless card disabled there than enable it and everything will work just fine.

  1. Click on Ubuntu Icon
  2. Search for Drivers or hardware-drivers
  3. Open that up and enbale your wireless driver from there

Some t440 models do not come with a wireless card. Might be worth checking your devise manager.

We have ordered 50 and had manually install the card in everyone.
