Title:
  Lenovo miix 510 wifi adapter cannot be turned on

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  This problem appears when you first install ubuntu 18.04, 18.10, and
  19.10 on a Lenovo Miix 501 laptop. I have not tried previous versions
  of ubuntu.  After installation or update to a newer versio of ubuntu
  the network adaptor is set to off and cannot be turned on. I believe
  this is because of a non-existent or faulty driver for the intel 8260
  wifi adapter. It also could be that the driver is waiting for physical
  or keyboard switch to turn on the adapter. However, no such switch
  exists in this laptop model.

  The problem can be resolved by adding "blacklist ideapad_laptop" to
  the configuration file

  /etc/modprobe.d/blacklist.conf

  (this is for ubuntu 19.04. The filename and location are different for 18.04 and 18.10)
