I am encountering lot of drop outs and instability (constant drop out) with my Wifi on Lenovo x230 with card

Centrino Advanced-N 6205 Taylor Peak
Physical id: 0
bus info: pci@0000:03:00.0
logical name: wlp3s0
version:34
width: 64
clock: 33Mhz

Anything I tried to do, did not seem to resolve the issue. Please anybody has an idea about fixing it - driver update or something similar. I love my Linux, but I am pretty much noob.

Thank you very much in advance. Tomas

sudo apt remove backport-iwlwifi-dkms

resolved this problem caused by the dist-upgrade to 22.04 on ThinkPad T430.

I just found that there is a kernel bug registered about this issue, specifically when bluetooth is enabled.

A possible solution is to put the following line:

options iwlwifi 11n_disable=1

in the file

/etc/modprobe.d/iwlwifi.conf

However, this can affect your internet speed or possibly something else, depending on how your router is configured. But if your issues are caused by this bug, they may be much improved by this configuration.
