wifi won't connect (Dell Latitude, Intel 9560, iwlwifi)

Hey,

I recently bought a Dell Latitude 5491 (wifi module: Intel 9560, iwlwifi), it shipped with ubuntu, the wifi worked properly, however I didn't check the drivers/settings before deleting it.

I installed Arch, networking with ethernet and Android tethering works fine, available wifi networks are listed properly, but when I try to connect to one in NetworkManager connecting won't succeed. I'm not sure how to debug it, `dmesg -w` logs this during "connecting":

[   32.721969] audit: type=1131 audit(1544874254.186:39): pid=1 uid=0 auid=4294967295 ses=4294967295 msg='unit=systemd-hostnamed comm="systemd" exe="/usr/lib/systemd/systemd" hostname=? addr=? terminal=? res=success'

I tried to disable 802.11n according to the wiki: https://wiki.archlinux.org/index.php/Wi … on#iwlwifi , as far as I can tell it just added a bunch of 

[   57.309663] iwlwifi 0000:00:14.3: Unhandled alg: 0x707

to the log

full `dmesg -w` output: https://pastebin.com/PVw9E2fm (with disabled  802.11n)

Maybe I'm overlooking something obvious, but I don't know much about wifi drivers, therefore I'd be thankful for any kind of help
