Title:
  iwlwifi Intel 7260 Wifi disconnects

Status in Unity Linux:
  New
Status in “linux-firmware” package in Ubuntu:
  Fix Released

Bug description:
  I experience frequent disconnects and auth issues, never more than 30
  minutes without a disconnect. Sometimes dozens of disconnects in a few
  minutes.

  This happens with the default 7260-8 firmware.
  Tried replacing the -8 with -9 ucode. Failed to load due to API version. This loaded the -7 driver which seems to be more stable.

  Tested against 2.4ghz APs (Apple, Netgear, Linksys).
