  RTL8821AE wireless adapter sporadically stuck (rtl8821ae module)

Status in linux package in Ubuntu:

Bug description:

  this is affecting me from 14.04, and new kernel in 16.04 didn't help,
  so I decided to open this issue.

  I've tried the following options:

  $ cat /etc/modprobe.d/rtl8821ae.conf
  options rtl8821ae ips=0 fwlps=0 swlps=1 debug=5 msi=0

  without any luck.

  I connect to a wireless network, works for a few minutes, then traffic
  completely stop for a few minutes, then everything works again, for
  another random amount of minutes.
