Attached are the logs found under dmesg which show when the problem occurs. Found a way to avoid the problem to occurs but it leads to have an almost unusable WiFi as the transfer rate is limited to 15~16Mbits/sec ... by adding options iwlwifi 11n_disable=1 to /etc/modprobe.d/iwlwifi.conf there is no crash anymore but it renders the laptop very laggy on some situations... I have a double boot with Windows 11 on this laptop and can confirm that I have no problem even with heavy speed usage under Windows, never had annny crash related to WiFi under Windows, but sorry Windows is not a solution for me :) Others tests I've done : - tried with different Live USB : Fedora / Ubuntu / Mint : all failed so the problem could be related to a common issue with wilwifi drivers under Linux ? - tried to change some settings at the access point's side : Mercusys HALO H80X which is 3 nodes Wifi 6 AX3000 Mesh but didn't find any setting which permit to solve the problem. I do not have access to another Access Point to test if this could be the culprit ... - some more configurations under /etc/modprobe.d/iwlwifi.conf ( I will output them below in a separate attachment). Available and at your disposal to give some more informations and/or debug more if you need some more tests.
