Title:
  Wifi Adapter Fails to come up after restart. after power off works
  fine

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I just installed Ubuntu Gnome 16.04 on my Laptop and I have noticed
  that Wifi somtimes doesn't work. after observing the problem I have
  come to the conclusion that it doesn't work after a reboot. I need to
  power it off and then back on to get the WiFi adapter working. my
  laptop is HP Pavilion and using a Ralink RT3290 Wireless adapter.

  this is the dmesg output when it's working:
