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.

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
