I have just installed Ubuntu 14.04 on my new T470 and I cannot connect to the internet, can't see the wifi networks and wired Ethernet. I couldn't solve the problem with the suggestions on the internet.

$ ifconfig
lo    Link encap:Local Loopback
      inet addr:127.0.0.1  Mask:255.0.0.0
      inet6 addr: ::1/128 Scope:Host

$ lspci -knn | grep Net -A2

Install Ubuntu 16.04.2 LTS and your wireless adapter will immediately work.

Your hardware Intel Corporation Device [8086:24fd] (rev 78) is not supported by the 14.04 Ubuntu release.

  • Will the LTS kernel backported from Xenial to Trusty (14.04.5) work too? Apr 24, 2018 at 18:16
  • @DavidFoerster No, it won't. Trusty won't go beyond the 4.4.
