@gronki (and others): Posting comments on bugs marked as fixed is
unlikely to get you anywhere. If the reporter's problem is fixed and
yours is not, then it stands to reason that you're suffering from a
different problem. Wireless bugs in particular can have very similar
symptoms with different root causes.

The best course of action is to file a new bug to focus specifically on
your issue your issue by running 'ubuntu-bug linux' from a terminal.

  iwlwifi Intel 7260 Wifi disconnects

Status in Unity Linux:
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

  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).
