I have Intel Corporation Wireless card, wireless 8265 on HP notebook. The problem is that automaticaly disconnects randomly. It’s nighrmare. And when the notebook connects to my rooter , all other wifi devices are disconected.
I have tried the wicd network manager, also have tried downloading the intel drivers and replacing them. Also stoped the bluethoot and updagraded the linux kernel to the last version 4.15… . Nothing helps.
The problem is only when using battery
Here are some errors that I get using “dmesg -w”
failed to remove key (1, ff:ff:ff:ff:ff:ff) from hardware (-22)
disassociated from …:…:…:…:…:…:…:…: (Reason: 14=MIC_FAILURE)
May be it has something similar to that bug, but I don’t know how to tell the kernel to load particular version of the firmware if it is possible. But also this bug seems quite different because I don’t have this problem only on shutdown, I have it through the session.
So my question is how to solve this. I’ve tried like 5 hours to solve this and I’m tired.
The installation is one day old and is the last stable Manjaro installation with KDE. I wrote this from another computer. That is why I don’t provide all the logs.

also did try to turn off power management using this link, but with off and 1 insted of 0 , https://wiki.archlinux.org/index.php/Power_management#Network_interfaces.
The solution for me was to disable IPv6
Also I did try other things like making my router to work with Mixed mode, but without n, also I have selected chanel 11, and changed the WPA Encryption Algorithm to AES.
