8086:08b1 (rev 6b) [Dell XPS 13 9333] Issues with Intel 7260 network card

[Removed by request]

My Intel 7260 network card regularly shows very poor performance and/or loses its connection entirely. When this happens I am forced to either disable/enable wifi or reboot my PC. The AP is never more than 5 meters away from my PC. I don't experience this when connected via cable. This also didn't happen on 12.04. I have also tried to install 3.13.0-37-generic #64+iwlltr0001 without any luck.

Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] (rev 6b)
 Subsystem: Intel Corporation Dual Band Wireless-AC 7260 [8086:c470]
