Intel AC 9560 Issue

Hello,

I'm using 5.3.8-arch1-1

uname -r
5.3.8-arch1-1

I'm getting several errors when looking at journalctl or dmesg about iwlwifi.

iwlwifi 0000:00:14.3: BIOS contains WGDS but no WRDS

This at the boot

iwlwifi 0000:00:14.3: Unhandled alg: 0x707

This generally all the time when I check journalctl.

I'm new to Arch and this forum too so I don't know how to post logs properly I apologize.

lspci -k results

Network controller: Intel Corporation Wireless-AC 9560 [Jefferson Peak] (rev 10)
    DeviceName: Onboard - Ethernet
    Subsystem: Intel Corporation Wireless-AC 9560 [Jefferson Peak]
    Kernel driver in use: iwlwifi
    Kernel modules: iwlwifi

Thanks for your respond.

Re: Intel AC 9560 Issue

something started going wrong with the iwlwifi drivers on some adapters, problems for me started about 1-2 months ago and seem to be caused by the way intel handles regulatory domain and incorrectly disables certain frequencies and makes it so only 20mhz channel width can be used on 5ghz ac access points which makes for bad performance.

in addition to the errors are you also having trouble seeing wireless ac access points (your router)?

from what i could gather intel uses 2 terms for the same technology.

LAR = Location Aware Regulatory
DRS = Dynamic Regulatory Solution

this parameter disables LAR and fixes this problem for me, might be worth a try

iwlwifi.lar_disable=1

or as a modprobe.d option line

options iwlwifi lar_disable=1
