Hi, everyone, I'm running Linux 5.10-rc7 with this firmware/hardware: [ 1.431878] iwlwifi 0000:02:00.0: loaded firmware version 29.198743027.0 7265D-29.ucode op_mode iwlmvm [ 1.431899] iwlwifi 0000:02:00.0: Detected Intel(R) Dual Band Wireless AC 3165, REV=0x210 Most of the time, after disabling/enabling Wi-Fi (or, say, rebooting the router), the card dies and only comes back after reboot.

Any ideas about what could be causing it? Thanks, Rui
