Public bug reported:

Running Ubuntu 14.04 since RC2

Desktop machine with Intel AC7260 + Bluetooth drops AC 5ghz wifi
connection.  No definitive pattern, but seems to drop more often when
running Transmission torrent client and while using ssh to connect to
home server.

2.4ghz N wifi is stable - 68-69/70 connection
5ghz AC wifi unstable - usually 52/70 connection

On Ubuntu 13.10 there was no AC wifi issue with this device.

Tried turning off Power Management in iwconfig, but no change in
connectivity.
