  8086:0887 very slow wifi

Status in “linux” package in Ubuntu:

Bug description:
  I had the same problem on Ubuntu 12.04, maybe a problem in the kernel.
  For no reason my wifi connection slowed down. I had less than 1B/s.

  WORKAROUND: sudo rmmod iwlwifi
  sudo modprobe iwlwifi 11n_disable=1

  and to apply this after reboot I created /etc/modprobe.d/iwlwifi.conf and add in it :
  options iwlwifi 11n_disable=1
