BruceWouaigne, as per http://www.asus.com/us/Notebooks_Ultrabooks/UX303LN/HelpDesk_Download/ an update to your BIOS is available (204). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?  If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, then please mark this report Status Confirmed.

Thank you for your understanding.

Title:
  [Inter 7260] Very slow and unstable WIFI

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Using an Asus Zenbook UX303L, with the last kernel, wifi is almost
  unusable. The connection is VERY slow and keeps dropping.

  There was absolutely no problem with the linux-image-3.13.0-40-generic
  kernel.

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

  lspci -knn | grep Net -A2

  02:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] (rev 6b)
      Subsystem: Intel Corporation Dual Band Wireless-N 7260 [8086:c160]
      Kernel driver in use: iwlwifi

  Here is the speedtest output with the last kernel:
