Hello Mathew,
It seems you were correct, and I must have been missing linux-modules or 
linux-modules-extra packages. Running the commands: 
$ sudo apt install linux-image-6.8.0-47-generic linux-modules-6.8.0-47-generic 
linux-modules-extra-6.8.0-47-generic linux-headers-6.8.0-47-generic
$ sudo apt install
$ sudo update-initramfs -c -k 6.8.0-47-generic
$ sudo update-grub
$ sudo reboot

worked, and I am running kernel 6.8.0-47-generic with no apparent
problems. Thank you for the help! What I don’t understand is why this
issue would only have appeared after the update, since I would presume
the same modules, albeit in potentially different versions, would have
had to have been installed for previous versions of the kernel, or the
same issue would have appeared, would it not?

Bug description:
  I am using Ubuntu 24.04.1 LTS.  After the upgrade to kernel 6.8.0-47
  from 6.8.0-45, for the first time, Ubuntu was unable to recognize my
  ethernet, wifi and bluetooth. None of these issues occurred before
  since they were automatically recognized and configured by the
  installer. The only solution I found was to revert to 6.8.0-45.
