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.
