Few days ago I did a full system upgrade, and since then been having problems with wifi connection. It would randomly disconnect, sometimes I would be able to connect again, sometimes not.
I managed to narrow the problem down to
linux-firmware-20141201.38e5405-1
. This was the version picked up by the update. After downgrading to
linux-firmware-20141009.0e5f637-1
, the problem disappeared.
I don't know if anybody else had this kind of problem, but just wanted to post in case somebody runs into it. I'm running HP laptop with intel wireless controller. This is the relevant lspci output:
02:00.0 Network controller: Intel Corporation Wireless 7260 (rev 73)

If any more info is needed, please let me know

I have exactly the same problem with a Dell XPS 15. It made my laptop unusable as it would loose the connection or I couldn't reconnect after a suspend until I did a full reboot. Downgrading the firmware worked. Anyone has a better solution?

Same problem here after upgrading the system.
I own the same WiFi card in an HP Elitebook 840G1 laptop.
I was getting very long connection time, random connection losses... very slow data rate : well, the wifi was barely usable
I didn't tried to downgrade the linux-firmware package version but I did something else.
I use TLP as power management tool. I was able to get back the usual behavior after disabling the WIFI power management option in /etc/defaults/tlp
This may not be the best solution from battery duration perspective but the wifi is back
