[1.] One line summary of the problem:
Intel 7265 wireless performance unstable on Linux >= 3.19
[2.] Full description of the problem/report:
When in kernel >= 3.19, using iwlwifi and the 7265D firmwares
(iwlwifi-7265D-12.ucode 25.15.12.0, or iwlwifi-7265D-10.ucode 23.15.10.0), I am
experiencing the following issues:
* On 5GHz 802.11ac, I'll get DEAUTH_LEAVING almost exactly every minute,
followed by an immediate reconnect (consistently reproducible).
* On both 2.4GHz and 5GHz, all network activity will cease after 10-20
minutes. A manual reconnect will temporarily fix network activity (not
consistently reproducible).
Due to the co-dependencies of the 3.19 iwlwifi modules and the new 7265D
firmwares, I believe I am not able to do a kernel bisect in this situation.
Linux 3.18 and older with the old 7265 (non-D, level 9) firmware worked
correctly.
Client is a Lenovo Thinkpad X250, latest firmware (1.07). AP is an ASUS
RT-AC87R (retail version of the RT-AC87U, same hardware), latest firmware
(3.0.0.4.378_4608-g7e6c1e5), in WAP-only mode.
