I'm having the same problem. Have a Dell XPS 15 with Network controller: Intel Corporation Wireless 7260 (rev 6b). Wifi link constanlty drops. Disabling power management and 11n_disable stablizes the connection a bit so I no longer get dropped off but wifi link is still very slow (it varies from minute to minute but over all still very slow). Running Ubuntu 14.04 LTS
