  rtl8821ae WiFI does not work

Status in linux package in Ubuntu:

Bug description:
  rtl8821ae does not work out-of the box on Ubuntu 16.04. It does not
  detect any WIFi networks and laptop starts with Wifi disabled in
  NetworkManager. To make rtl8821ae work I have to do the following:

  echo "blacklist ideapad_laptop" | sudo tee /etc/modprobe.d/idepad.conf

  After that rtl8821ae loses connection occasionally. None of those helped:

  echo rtl8812ae  >>  /etc/modules
  echo "options rtl8821ae ips=0 fwlps=0" | sudo tee 
  sudo modprobe -r rtl8821ae && sudo modprobe rtl8821ae
  options rtl8821ae ips=0 swenc=1 debug=5 msi=0
  sudo iw dev wlp2s0 set power_save off

  Installing new driver from here did not help.
