Ubuntu Version:
24.04 LTS, 6.14.0-36-generic #36~24.04.1-Ubuntu SMP PREEMPT_DYNAMIC
Desktop Environment (if applicable):
XFCE
Problem Description:
I am having problems of the kind
“kernel: wlp2s0: HW problem - can not stop rx aggregation for 8c:86:dd:c6:fa:b4 tid 6”
for a Intel Corporation Dual Band Wireless-AC 3168NGW [Stone Peak] (rev 10)
on Ubuntu 24.04 LTS with newest updates.
Wifi is interrupted then.
I already tried options iwlwifi 11n_disable=1 in /etc/modprobe.d/iwlwifi.conf
but this is not a real solution, it only makes Wifi slower.
It does appear when having larger downloads and e.g. with speedtest.net .
Is there some newer iwlwifi version I can try?

wireless-tools 30~pre9-16.1ubuntu2 is there and seems to be the latest version.
For some reasons
linux-modules-iwlwifi-6.14.0-36-generic is not installed according to
synaptic, but there is:
# modinfo iwlwifi
filename: /lib/modules/6.14.0-36-generic/kernel/drivers/net/wireless/intel/iwlwifi/iwlwifi.ko.zst
license: GPL

Do I have to reinstall this after going to the hwe kernel?
