My Intel 7265 used to work flawlessly, but for the past week or two it has seemed to be very unreliable. It's also throwing errors. I see problems on firmware versions 16 and 21, although I haven't gotten the warning and backtrace on firmware 16 yet. I have: iwlwifi 0000:3a:00.0: enabling device (0000 -> 0002) iwlwifi 0000:3a:00.0: Unsupported splx structure iwlwifi 0000:3a:00.0: loaded firmware version 21.302800.0 op_mode iwlmvm iwlwifi 0000:3a:00.0: Detected Intel(R) Dual Band Wireless AC 7265, REV=0x210 iwlwifi 0000:3a:00.0: L1 Enabled - LTR Disabled iwlwifi 0000:3a:00.0: L1 Enabled - LTR Disabled I just got this error on 4.7.0: [324188.495734] wlp58s0: associated [324281.259579] iwlwifi 0000:3a:00.0: Queue 16 stuck for 10000 ms.
