Downgrading linux-firmware to 1.127.4 didn't solve the problem, today It
had the same problem:

Title:
  iwlwifi problem causes repeated disconnections to wireless network

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  After having iwlwifi problems of constant disconnections every 30 or
  so minutes, I tried going to
  http://wireless.kernel.org/en/users/Drivers/iwlwifi to install the
  latest Intel® Wireless 7260 firmware for my kernel version at
  /lib/firmware, having only the -8 or -7 version in that directory,
  restarting my computer, and reinstalling the linux-firmware 1.127.6
  package.
