No networking after automatic updates

Question

I ran the Software Updater on my server rig, and now the networking doesn't work, even locally. There's no wifi and no ethernet.

I ran this:

$ cat /etc/netplan/01-network-manager-all.yaml

And got this:

# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager

Is there a way to see what updates I recently installed to see where this might have stemmed from? Or a way to fix this entirely?

EDIT 1: Ran:

sudo dpkg -s linux-modules-extra-$(uname -r) | grep Status

And received:

dpkg-query: package 'linux-modules-extra-5.15.0-70-generic' is not installed and no information is available

EDIT 2: Ran: ip a and received:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever

Also ran iwconfig and received lo no wireless extensions.

EDIT 3: I also did the steps in the following post. It did not work. Ubuntu doesnt detect wifi or ethernet. *-network UNCLAIMED in Windows / Ubuntu dual boot

EDIT 4: sudo dpkg -s linux-modules-extra-$(uname -r) | grep Status returns Status: install ok installed

And sudo lshw -C network shows that my network adapters are unclaimed.

EDIT 5: Input sudo modprobe ath9k and got modprobe: ERROR: could not insert 'ath9k': Operation not permitted

Then input ps aux | grep Network and got:
