[Resolved] Frequent wifi disconnects with reason code 2

Hello Arch community,

I'm having a rather weird issue with my system - I have periodic wifi disconnects that seem to happen every 10 minutes.

journalctl -u iwd.service

lspci:
29:00.0 Network controller: Intel Corporation Dual Band Wireless-AC 3168NGW [Stone Peak] (rev 10)

kernel:
5.9.1-arch1-1 (latest, up to date)

IWD:
iwd 1.9-1

Already tested:
- removed and re-added the wifi
- changed frequency / SSID of the wifi
- Reviewed 802.11 specification for reason code 2 == previous authentication no longer valid
- tested network manager backend for IWD > same issue (NM is deactivated, using only iwd with dhcp)

Has anyone ever seen something like this or can point me into the right direction?
This is the only affected system in my wireless network.

The router I use is a Fritzbox type 6591, 2,4 / 5 GHz, country specific configuration is applied to the system.
Authentication is WPA2 with CCMP

Any help greatly appreciated as this is really annoying.

Thank you and best regards,
Alex

Re: [Resolved] Frequent wifi disconnects with reason code 2

Appears to be resolved by creating / modifiying the /etc/iwd/main.conf

[General]
ControlPortOverNL80211=False

I had a similar issue but kernel 5.9.2 has a patch that fixes it for me. Have you tried ti with 5.9.2 ?

Had the same problem and can confirm that kernel 5.9.2 solves the problem on its own.
