You have been subscribed to a public bug:

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:
