I've just got a Lenovo X1 Carbon (5th generation). When I installed Ubuntu 16.04 LTS off an USB the Wifi was working from the point go.

However at some point during the setup process the Wifi card stopped working. The card is identified as a Intel WiGig 18265AC+BT 2x2 vPro in the specsheet.

The network dropdown on the system bar reads:

Wi-Fi Networks 
device not ready 
Mobile Broadband 
not enabled

Bluetooth is not accessible either. I've had a look around via Google but haven't found any solution that works.

What is the best approach to get this up and running?

I had a simiar problem, except that wifi never worked for me, even using the USB drive. What worked for me was changing kernel to the most recent one that I found available using 

apt-cache search linux-image-extra

I changed kernel using the following commands:

sudo apt-get install linux-image-4.11.0-14-generic linux-headers-4.11.0-14-generic linux-image-extra-4.11.0-14-generic

(But using the commands suggested in another comment here

sudo apt-get autoremove
sudo service network-manager restart

did fix my bluetooth, so thanks!)

When I upgraded to Ubuntu 17.04 all of the network functions worked:

  • Ethernet
  • Wifi
  • Mobile Broadband
  • Bluetooth

In the end the following commands got me up and running:

sudo apt-get autoremove
sudo service network-manager restart

At a guess there were conflicting unused drivers.
