I'm running Ubuntu 22.10 with an Intel Wifi AX210 chip. It's a fresh install and I've been using Wifi all day until suddenly it stopped working and I see a question mark where the Wifi symbol should be. The internet definitely works, something is up with my machine.
Here's outputs from various commands in solutions I've tried

Looks like the problem might be here:
Direct firmware load for iwlwifi-ty-a0-gf-a0-72.ucode failed with error -2
[ 4.052106] iwlwifi 0000:06:00.0: api flags index 2 larger than supported by driver
Looking around I saw suggestions to add the following to /etc/modprobe.d/iwl.conf:
options iwlwifi 11n_disable=1 swcrypto=0 bt_coex_active=0 power_save=0
options iwlmvm power_scheme=1
options iwlwifi d0i3_disable=1
options iwlwifi uapsd_disable=1
options iwlwifi lar_disable=1
In my case that didnt help. Actually I didnt have a iwl.conf, I created it. I did already have a iwlwifi.conf, and I tried adding those params there as well to no avail.
The content of that file were previously:
remove iwlwifi \
(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
&& /sbin/modprobe -r mac 80211
When I tried putting the param in that file I added them before the contents.
When I made changes to either of those configs I restarted of course.
