[Seth Forshee <seth.forshee+lp@xxxxxxxxxxxxx>]

Daniel: We recently incorporated some fixes into 14.04 to fix some
disconnection issues seen with Intel 7260 wireless. Could you ensure
that your system is fully up to date, reboot (making sure that you boot
into the official trusty 3.13 kernel and not any newer kernel which you
installed for testing), and let me know whether or not you're still
having problems? If you are then we can continue trying to debug your
issue.

Everyone else: Unless you have the exact same machine as Daniel, please
open a new bug for your issue if you haven't already. Feel free to
subscribe me to your bug.

Thanks!

Title:
  8086:08b1 (rev 6b) [Sony VAIO SVP1321M2E] Wifi keeps dropping.

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Using a Sony Vaio Pro 13 with Ubuntu 14.04 the wifi keeps dropping. Sometimes all the time, at times after a bit longer (~10 min). A few packages ago it didn't drop, but was really, really, slow. Now it completely drops. Adding the following to modprobe.conf made no change:
  options iwlwifi 11ac_disable=1
  options iwlwifi 11n_disable=1

  After each new row I ran:
  sudo modprobe -rfv iwlwifi
  sudo modprobe -v iwlwifi

  Tried turning off the power management of wlan0 without any change.

  Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] (rev 6b)
  Subsystem: Intel Corporation Dual Band Wireless-N 7260 [8086:c060]

  WORKAROUND: Within 2 m I have full speed, but still disconnects.
