Description Vasiliy Kovalev 2023-07-05 13:48:25 UTC
Hello,

the wi-fi network disconnection always occurs at different times after the system is started - from 1 minute to half an hour, it is not possible to trace the cause.

The error is reproduced on all tested cores: 5.10, 5.15, 6.1, 6.3

Attempts to apply the following kernel parameters are unsuccessful:
pcie_aspm=off
powersave=off
pcie_port_pm=off

Attempts to add options for iwlmvm and iwlwifi modules have also been unsuccessful:
options iwlwifi 11n_disable=1 swcrypto=0 bt_coex_active=0 power_save=0
options iwlmvm power_scheme=1
options iwlwifi d0i3_disable=1
options iwlwifi uapsd_disable=1
options iwlwifi lar_disable=1
options iwlwifi 11n_disable=8 swcrypto=1

options iwlwifi power_save=0
options iwlmvm power_scheme=1
options iwlwifi d0i3_disable=1
options iwlwifi uapsd_disable=1
options iwlwifi lar_disable=1
options iwlwifi 11n_disable=8 swcrypto=1
