I have worked around the issue by setting my wifi router to the 'up to
54 Mbit/s' mode instead of 300 Mbit/s as it was initially. A proper fix
would still be much appreciated, but this way it at least stopped
constantly disconnecting.

Same problem on Lenovo Carbon X1 gen2 with Intel Wireless 7260 (rev 83).
Using Ubuntu 15.04 with 3.19.0-21 kernel (x86_64).
Bluetooth is soft-blocked with rfkill but this does not solve the problem.
I constantly get disconnects:

I can confirm that 802.11ac mode seems to make the link more unstable -
especially the 5 GHz network.
However, I discovered that with Ubuntu 15.04 and the 3.19.0-21 kernel,
turning off power management improves the stability a lot.
