With both done, I see things like that:
[  690.597221] iwlwifi 0000:06:00.0: L1 Enabled; Disabling L0S
[  690.601979] iwlwifi 0000:06:00.0: Radio type=0x1-0x2-0x0
[  690.644716] iwlwifi 0000:06:00.0: U iwl_power_sleep_cam_cmd Sleep command for CAM
[  690.644721] iwlwifi 0000:06:00.0: U iwl_set_power Sending power/sleep command
[  690.644724] iwlwifi 0000:06:00.0: U iwl_set_power Flags value = 0x00000000
[  690.644726] iwlwifi 0000:06:00.0: U iwl_set_power Tx timeout = 0
[  690.644728] iwlwifi 0000:06:00.0: U iwl_set_power Rx timeout = 0
[  690.644731] iwlwifi 0000:06:00.0: U iwl_set_power Sleep interval vector = { 0 , 0 , 0 , 0 , 0 }
[  690.645649] iwlwifi 0000:06:00.0: U iwl_power_sleep_cam_cmd Sleep command for CAM

Does this help you, or do you need more?

Best wishes

Norbert

SNITTER (n.)
One of the rather unfunny newspaper clippings pinned to an office
wall, the humour of which is supposed to derive from the fact that the
headline contains a name similar to that of one of the occupants to
the office.
